JSJ 269 Reusable React and JavaScript Components with Cory House

JSJ 269 Reusable React and JavaScript Components with Cory House

On today’s episode of JavaScript Jabber, we have panelists Joe Eames, Aimee Knight, Charles Max Wood, and playing the part of both host and guest, Cory House. Encourage your team to investigate reusable components, whether that’d be React, Angular, Vue, or Ember. Tune in!

[00:01:35] – Overview

We can finally write reusable components that it is really lightweight. It doesn’t take much framework-specific code to get things done.

Around 3 years ago, the idea of web component standard was all front-end developers could share our components with each other whether someone is in Angular or React. Web components continue to be an interesting standard but people continue to reach for JavaScript libraries instead – React, Angular, Vue. 

[00:04:50] – Browser support issue

The story in JavaScript libraries is easier. You have more power, more flexibility, more choices, and get superior performance, in certain cases, by choosing a JavaScript library over the standard right now. If you try to use the web components standard, you have to Polyfill-in some features so you can run things across browser. You also won’t get JavaScript features like intelligently splitting bundles and lazy load different components.

Whether you’re in Angular or React, you have this model of putting your data in your curly braces. That setup is non-existent in standardized web components. You have to play the game of putting and pulling data into and out the DOM using DOM selectors. You actually take a step backward in developer ergonomics when you choose to leverage the platform instead.

[00:07:50] – Polymer

The reason that Polymer is useful is it adds some goodness on top of web components. One of those things is that it makes it easier to bind in data and not having to do things like writing a DOM query to be able to get your hands on this div and put this text inside of it. With Polymer, you can do something that feels more like Angular, where you can put in your curly braces and just bind in some data into that place. Polymer ends up adding some nice syntactic sugar on top of the web components standard just to make it easier to create web components. Polymer is also used to bundle in Polyfill for the features across browser.   

[00:14:20] – Standards are dead

No. The standard itself has been embraced at different levels by different libraries. What you can see for the near future is popular libraries leveraging pieces of the web components platform to do things in a standard-spaced way. Effectively, Angular, Vue, Aurelia, are going to be abstractions over the web components standard. Arguably the most popular way to do components today is React. But React completely ignores the web components standard. When you look at React, you can’t see what piece of the web components standard would fundamentally make React a better component library.

Cory can’t seem to run to anybody that is actually using the standard in production to build real applications. People continue to reach for the popular JavaScript libraries that we so often hear about.

[00:17:05] – Libraries making reusable components

There is a risk that it would have been a waste for people writing components on Angular, for React, for Vue. But it’s not necessarily safer writing on the web component standard when you have so few people leveraging that standard. There’s always the risk that that standard may shift as well.

As an example, Cory’s team created approximately 100 reusable components in React. If they end up moving to a hot new library, the components are really just functions that take parameters and contain HTML. There is little there

[00:21:20] – Why opt for reusable components

Reusable components are inherently useful in a situation where you’re going to be doing something more than once. If you think about any work that you do as a software developer, we’d like to think that we’re coming in and creating new things but often it is groundhogs day. There are all sorts of opportunities for reuse.

As a company, we want to encapsulate our forms in reusable components so it’s literally impossible for our software developers to do something that goes against our standard. That’s the power of reusable components.  

[00:31:20] – Rigid component vs. flexible component

As component developers, if we try to create a reusable component in a vacuum, bad things happen. If you’re going to do a reusable component, start by solving a specific problem on a given application. If we think that a component’s going to be useful in multiple places, we put it in a folder called reusable right there in our application source folder.

We try to follow that rule of three as well. If we’ve taken that component and used it in 3 places, that’s a good sign that we should extract it out, put it in our NPM package, that way, everybody has this centralized component to utilize. At that point, it has been tested. It’s been through the fire. People have used it in the real world in a few places so we can be confident that the API is truly flexible enough.

Be as rigid as you can upfront. Once you add features, it’s really hard to take features away. But it’s quite easy to add features later. If you start with something rigid, it’s easier to understand. It’s easier to maintain and you can always add a few more switches later.

[00:36:00] – Reusable components

The reason that we can’t reuse code is every time a new project comes up, people are spending up their own ideas rather than leveraging standards that should have been put in place previously.

We’ve had the technical ability to do this for a long time. We just haven’t been around long enough for consolidation to happen, for standardization to happen. You look at how quickly things are changing in our industry. For instance, a couple of years ago, everybody had pretty much decided that two-way binding was the way to build web applications. And then, React came along and shook that up. So today, you have different ways of thinking about that issue.

[00:42:45] – Component development on teams

Aimee’s team has component development and they’re using Angular 1.6. All of our base components are sitting in a seed application. We just go in when we want to create a new property and we just extend all of those components with specific functionalities that we need.

[00:47:45] – Mobile to web crossover

Cory’s team is creating React components but it’s not leveraged on a mobile application. But people use React Native components on the web. And in fact, if you use create-react-app today, you can do that right now. It’s wired up to work in React Native components. In that way, you can literally have these same components running on your Native mobile apps as you do on your web application.

[00:50:00] – Challenge

Cory’s challenge for everybody listening is sit down with your team and have a quick conversation about whether you think components make sense. Look back at the last few months of development and say, "if we have a reusable component library, what would be in it? How often have we found ourselves copying and pasting code between different projects? How much benefit would we get out of this story?"

Once you’ve realized the benefits of the component model, both in the way that makes you think about your application, in a way that it helps you move faster and faster over time, I really think you won’t go back to the old model. I’d encourage people to investigate reusable components, whether that’d be React, Angular, Vue or Ember.

JSJ 271: SharePoint Extensions in JavaScript with Mike Ammerlaan and Vesa Juvonen

JSJ 271: SharePoint Extensions in JavaScript with Mike Ammerlaan and Vesa Juvonen

This episode is a live episode from Microsoft Build where AJ O'Neal and Charles Max Wood interview Mike Ammerlaan and Vesa Juvonent about building extensions for SharePoint with JavaScript.

[00:01:28] Mike Ammerlaan introduction
Mike has worked at Microsoft for a long time on multiple Microsoft products and projects. He's currently on the Office Ecosystem Marketing Team.

[00:01:52] Vesa Juvonen introduction
Ves a is Senior Program Manager for the SharePoint Splat team. He's been with Microsoft for about 11 years and manages the community and documentation for the SharePoint framework.

[00:02:18] What is the SharePoint Framework?
This is how you write SharePoint extensions with JavaScript. SharePoint has changed. It now works with common modern development tools and web development techniques. SharePoint consolodates the extension effort

[00:03:32] What is SharePoint?
File sharing, team sites, communication points for teams. Part of Office 365. You use Web Parts to add functionality to SharePoint. Web Parts provide functionality like widgets and are scoped to a team, group, or set of users. It's usually hosted on premises, but you can also use it with Office 365 as a hosted solution.

[00:05:56] What extensions can you build for SharePoint?
You can build widgets for your front page or intranet. You can also add user management or data management or document management.

Examples:

  • Dashboards
  • Mini Applications
  • Scheduling and Time Tracking
  • Document Storage
  • Source code repositories

[00:07:39] What is WebDAV and how does it relate?
WebDAV is a protocol for accessing documents and SharePoint supports it among other protocols for managing documents.

[00:08:36] Do I have to build front-end and back-end components to get full functionality?
You can build the front-end UI with Angular and other frameworks. And then build a service in Azure on the backend. The backend systems can then access Line of Business systems or other data systems.

It really does take multiple skill sets to build extensions for SharePoint.

[00:11:10] SharePoint on Mobile
There is a mobile web app and the Web Parts work through the mobile application. You can also use any browser to connect to the application.

[00:12:08] Building extensions with standard Angular or React component libraries
There are standard Yeoman templates. You can also pull in the components through React or Angular just like what Microsoft does.

Newer Angular versions are designed for Single Page Apps and SharePoint isn't necessarily set up to work that way. The Web Parts are isolated from each other and Angular requires some workarounds.

[00:14:30] Getting around sandboxing
Google and Microsoft are talking to each other to see how to work around this when there are multiple sandboxed applications that can't talk to each other in very simple ways.

[00:15:39] Application library or naming collisions if my UI uses different versions or clobber page wide settings
There are guides for a lot of this. React does a bunch of the isolation work.

Addons are iframed in and an API token is given to grant access to the data and APIs.

Microsoft also reviews and approves plugins.

[00:18:30] How do you get started and make money at this?
Look at the SharePoint store. You can build things through websites and pages and offer the plugins through the store.

You can request a SharePoint tenant installation from the Microsoft Dev Tools for free. Then you can build into the tenant site. The rest of the tools are available on npm.

SharePoint Developer Tools

[00:22:13] Automated testing for SharePoint extensions
Unit testing is built in for JavaScript. Testing the UI's require you to sign into Office 365. There are people doing it, though.

[00:22:54] Building internal-only extensions
SharePoint is an enterprise tool, so a lot of enterprises may not want to install extensions from the store. You can definitely build and install private plugins for SharePoint setups. They also have their own backend systems that will require custom development.

[00:25:50] Office 365, SharePoint, and OneDrive
Office 365 is used by people across many different sized organizations and SharePoint is much more enterprise. Office 365 tools store files and information in SharePoint.

What about OneDrive versus Sharepoint? OneDrive is focused for one person. SharePoint is focused around a team. But they have the same APIs and use the same technology stack.

[00:29:05] The history and future of SharePoint
It started out on premises and has moved to the cloud. The SharePoint team is working to keep it available and useful in the modern cloud based era.

[00:30:25] What does the API footprint look like?
It spans modifying lists, data objects, attributes, items in a list, put Web Parts on a page, modify the experience, and manage and modify access, users, and documents. SharePoint is a way of building a way of conveying information.

SharePoint is layers of data and scopes.

[00:35:26] Tutorials and Open Source
dev.office.com
The Sharepoint framework is not open source yet, but they're working on that. They also need to open source the Yeoman templates.
Open source samples are available at github.com/sharepoint.

JSJ 275: Zones in Node with Austin McDaniel

JSJ 275: Zones in Node with Austin McDaniel

The panel for this week on JavaScript Jabber is Cory House, Aimee Knight, and Charles Max Wood. They speak with special guest Austin McDaniel about Zones in Node. Tune in to learn more about this topic!

[00:01:11] Introduction to Austin

Austin has worked in JavaScript for the past ten years. He currently works in Angular development and is a panelist on Angular Air. He has spent most of his career doing work in front-end development but has recently begun working with back-end development. With his move to back-end work he has incorporated front-end ideas with Angular into a back-end concept.

[00:02:00] The Way it Works

NodeJS is an event loop. There is no way to scope the context of a call stack. So for example, Austin makes a Node request to a server and wants to track the life cycle of that Node request. Once deep in the scope, or deep in the code, it is not easy to get the unique id. Maybe he wants to get the user from Passport JS. Other languages – Python, Java – have a concept called thread local storage. They can associate context with the thread and throughout the life cycle of that request, he can retrieve that context.

There is a TC39 proposal for zones. A zone allows you to do what was just described. They can create new zones and associate data with them. Zones can also associate unique ids for requests and can associate the user so they can see who requested later in the stack. Zones also allow to scope and create a context. And then it allows scoping requests and capturing contacts all the way down.

[00:05:40] Zone Uses

One way Zone is being used is to capture stack traces, and associating unique ids with the requests. If there is an error, then Zone can capture a stack request and associate that back to the request that happened. Otherwise, the error would be vague.

Zones are a TC39 proposal. Because it is still a proposal people are unsure how they can use it. Zones are not a new concept. Austin first saw Zones being used back when Angular 2 was first conceived. If an event happened and they wanted to isolate a component and create a scope for it, they used Zones to do so. Not a huge fan of how it worked out (quirky). He used the same library that Angular uses in his backend. It is a specific implementation for Node. Monkey patches all of the functions and creates a scope and passes it down to your functions, which does a good job capturing the information.

[00:08:40] Is installing the library all you need to get this started?

Yes, go to npminstallzone.js and install the library. There is a middler function for kla. To fork the zone, typing zone.current. This takes the Zone you are in and creates a new isolated Zone for that fork. A name can then be created for the Zone so it can be associated back with a call stack and assigned properties. Later, any properties can be retrieved no matter what level you are at.

[00:09:50] So did you create the Zone library or did Google?

The Google team created the Zone library. It was introduced in 2014 with Angular 2. It is currently used in front-end development.

[00:10:12] Is the TC39 proposal based on the Zone library?

While Austin has a feeling that the TC39 proposal came out of the Zone library, he cannot say for sure.

[00:10:39] What stage is the proposal in right now?

Zone is in Stage Zero right now. Zone JS is the most popular version because of its forced adoption to Angular. He recommends people use the Angular version because it is the most tested as it has a high number of people using it for front-end development.

[00:11:50] Is there an easy way to copy the information from one thread to another?

Yes. The best way would probably be to manually copy the information. Forking it may also work.

[00:14:18] Is Stage Zero where someone is still looking to put it in or is it imminent?

Austin believes that since it is actually in a stage, it means it is going to happen eventually but could be wrong. He assumes that it is going to be similar to the version that is out now. Aimee read that Stage Zero is the implementation stage where developers are gathering input about the product. Austin says that this basically means, “Implementation may vary. Enter at your own risk.”

[00:16:21] If I’m using New Relic, is it using Zone JS under the hood?

Austin is unsure but there something like that has to be done if profiling is being used. There has to be a way that you insert yourself in between calls. Zone is doing that while providing context, but probably not using Zone JS. There is a similar implementation to tracing and inserting logging in between all calls and timeouts.

[00:17:22] What are the nuances? Why isn’t everybody doing this?

Zone is still new in the JavaScript world, meaning everyone has a ton of ideas about what should be done. It can be frustrating to work with Zone in front-end development because it has to be manually learned. But in terms of implementation, only trying to create a context. Austin recommends Zone if people want to create direct contacts. The exception would be 100 lines of Zone traces because they can get difficult.

Another issue Austin has is Node’s native basic weight. Weight hooks are still up in the air. The team is currently waiting on the Node JS community to provide additional information so that they can finish. Context can get lost sometimes if the wrong language is used. He is using Typescript and doesn’t have that problem because it is straightforward.

[00:21:44:] Does this affect your ability to test your software at all?

No, there have not been any issues with testing. One thing to accommodate for is if you are expecting certain contexts to be present you have to mock for those in the tests. After that happens, the tests should have no problems.

JSJ 338: It’s Supposed To Hurt, Get Outside of Your Comfort Zone to Master Your Craft with Christopher Buecheler

Panel:

Special Guests: Christopher Buecheler

In this episode, the panel talks with Christopher Buecheler who is an author, blogger, web developer, and founder of CloseBrace. The panel and Christopher talk about stepping outside of your comfort zone. With a technological world that is ever changing, it is important to always be learning within your field. Check out today’s episode to learn more!

Show Topics:

0:00 – Advertisement: KENDO UI

1:08 – Aimee: Our guest is Christopher Buecheler – tell us about yourself and what you do.

1:22 – Guest: I run a site and help mid-career developers. I put out a weekly newsletter, too.

2:01 – Aimee: It says that you are a fan of “getting comfortable being uncomfortable”?

2:15 – Guest: I am a self-taught developer, so that means I am scrambling to learn new things all the time. You are often faced with learning new things. When I learned React I was dumped into it. The pain and the difficulty are necessary in order to improve. If you aren’t having that experience then you aren’t learning as much as you could be.

3:26 – Aimee: I borrow lessons that I learned from ice-skating to programming.

3:49 – Guest: I started running a few years ago for better health. It was exhausting and miserable at the start and wondered why I was doing it. Now I run 5 times a week, and there is always a level of being uncomfortable, but now it’s apart of the run. It’s an interesting comparison to coding. It’s this idea of pushing through.

5:01 – Aimee: If you are comfortable you probably aren’t growing that much. In our industry you always have to be learning because things change so much!

5:25 – Guest: Yes, exactly. If you are not careful you can miss opportunities.

6:33 – Panel: You have some ideas about frameworks and libraries – one thing that I am always anxious about is being able to make sense of “what are some new trends that I should pay attention to?” I remember interviewing with someone saying: this mobile thing is just a fad. I remember thinking that she is going to miss this opportunity. I am worried that I am going to be THAT guy. How do you figure out what sort of things you should / shouldn’t pay attention to?

7:47 – Guest: It is a super exhausting thing to keep up with – I agree. For me, a lot of what I pay attention to is the technology that has the backing of a multi-million dollar company then that shows that technology isn’t going anywhere, anytime soon. The other thing I would look at is how ACTIVE is the community around it?

9:15 – Panel: Is there a strategic way to approach this? There is so many different directions that you can grow and push yourself within your career? Do you have any kinds of thoughts/tips on how you want your career to evolve?

10:00 – Guest: I am trying to always communicate better to my newsletter audience. Also, a good approach, too, is what are people hiring for? 

11:06 – Aimee: Again, I would say: focus on learning.

11:30 – Panel: And I agree with Aimee – “learn it and learn it well!”

12:01 – Panel: I want to ask Chris – what is CloseBrace?

12:17 – Guest: I founded it in November 2016, and started work on it back in 2013.

14:20 – Panel: It was filled with a bunch of buzz worthy words/title.

14:32 – Guest continues his thoughts/comments on CloseBrace.

16:54 – Panel: How is the growth going?

17:00 – Guest: It is growing very well. I put out a massive, massive tutorial course – I wouldn’t necessarily advice that people do this b/c it can be overwhelming. However, growth this year I have focused on marketing. I haven’t shared numbers or anything but it’s increased 500%, and I am happy about it.

18:05 – Panel: Are you keeping in-house?

18:13 – Guest: I think it would be cool to expand, but now it is in-house. I don’t want to borrow Egg Head’s setup. I would love to cover MORE topics, though.

19:05 – Panel: You are only one person.

19:08 – Guest: If I can get the site creating more revenue than I can hire someone to do video editing, etc.

19:35 – Panel: I think you are overthinking it.

19:45 – Guest.

19:47 – Advertisement – Sentry.io

20:47 – Guest.

21:30 – Aimee: There are SO many resources out there right now. Where do you think you fit into this landscape?

21:44 – The landscape is cluttered, but I feel that I am different b/c of my thoroughness. I don’t always explain line by line, but I do say how and why things work. I think also is my VOICE. Not my radio voice, but the tone and the approach you take with it.

23:25 – Panel: I was trying to copy folks in the beginning of my career. And at some point I realized that I needed to find my own style. It always came down to the reasons WHY I am different rather than the similarities. Like, Chris, you have these quick hits on CloseBrace, but some people might feel like they don’t have the time to get through ALL of your content, because it’s a lot. For me, that’s what I love about your content.

24:46 – Christopher: Yeah, it was intentional.

25:36 – Panel: Good for you.

25:49 – Guest: I am super device agnostic: Android, Mac, PC, etc. I have a lot of people from India that are more Microsoft-base.

26:28 – Aimee: I think Egghead is pretty good about this...do you cover testing at all with these things that you are doing? It’s good to do a “Hello World” but most of these sites don’t get into MORE complex pieces. I think that’s where you can get into trouble. It’s nice to have some boiler point testing, too.

27:18 – Guest answers Aimee’s question.

28:43 – Aimee: We work with a consultancy and I asked them to write tests for the things that we work with. That’s the value of the testing. It’s the code that comes out.

29:10 – Panel: Can you explain this to me. Why do I need to write tests? It’s always working (my code) so why do I have to write a test?

29:39 – Guest: When working with AWS I was writing...

31:01 – Aimee: My biggest thing is that I have seen enough that the people don’t value testing are in a very bad place, and the people that value testing are in a good place. It even comes back to the customers, because the code gets so hard that you end up repeatedly releasing bugs. Customers will stop paying their bills if this happens too often for them.

33:00 – Panel: Aimee / Chris do you have a preferred tool? I have done testing before, but not as much as I should be doing.

33:25 – Aimee: I like JEST and PUPPETEER.

33:58 – Guest: I like JEST, too.

0:38 – Chuck: Aimee, Chris, Joe, and myself – we are today’s panel. My show the DevRev is available online to check it out.

1:30 – Guest: Plain ice cream would be frozen milk and that would be terrible. So I am lemon and candy JavaScript!

2:13 – Chuck: We are talking today about...?

2:22 – Chris: He’s talking about “inclusive components” today!

2:41 – Guest: Traveling is very stressful and I wanted something to do on the plane. I’ve done this book, “Inclusive Design Patterns.”

If you don’t want to buy the book you can go to the blog. I have been talking with Smashing Magazine.

5:40 – Panel.

5:47 – Guest: I approached Smashing Magazine initially. They didn’t think there was a market for this content at the time. They were very supportive but we will do it as an eBook so our costs our down. At the time, the editor came back and said that: “it was quite good!” We skimmed it but came back to it now and now the content was more relevant in their eyes. I didn’t want to do the same book but I wanted to do it around “patterns.” Rewriting components is what I do all the time. I use Vanilla JavaScript. Backbone.js is the trendy one.

9:52 – Panel: The hard book did it get published?

10:02 – Guest: We are in the works and it’s all in the final stages right now. It has to go through a different process for the print version.

11:54 – Panel.

11:58 – (Guest continues about the editorial process.)

12:09 – Panel: They probably switched to TFS – it’s Microsoft’s.

12:23 – Guest: There was this argument on Twitter about the different processors.

13:35 – Chris: What are the ways that people are breaking accessibility with their code through JavaScript? 

13:59 – Guest: The whole premise is that there aren’t a ton of different components that we use. Generally, speaking. Most things we do through JavaScript – it’s just different ways of doing this/that, and hiding things. I am discounting things with Node or other stuff. Most of what we are doing, with interactive design, is showing and hiding.

18:37 – Chris: I have some specialty friends where they tell me where I’ve screwed up my code. For example Eric Bailey and Scott O’Hara but, of course, in very kind ways. What are some things that I can make sure that my code is going to work for many different people.

19:18 – Guest: You have accessibility and inclusive design. People think of accessibility as a check-list and that’s okay but there could be problems with this.

26:00 – Panel: That’s a great guideline.

26:05 – Chris: You talked about ARIA roles and it can be confusing. One side is: I don’t know when to use these and the other side is: I don’t know when NOT to use these so I’m going to use them for EVERYTHING! I guess both can be detrimental. What’s your advice on this topic?

27:00 – Guest: Scott is great and I would trust him to the end of the Earth about what he says.

Guest mentions Léonie Watson and her talks about this topic.

29:26 – (Guest continues.)

29:36 – Advertisement – Sentry.io

30:31 – Chris.

30:40 – Guest: There is a lot of pressure, though, right? People wouldn’t blog about this if it wasn’t worthwhile. It doesn’t matter what the style is or what the syntax is.

The guest talks about not throwing ARIA onto everything.

36:34 – Aimee: Is this something that was mentioned in the book: people with disabilities and accessibility.

37:28 – Guest: Yes, of course. I think it’s important to make your interfaces flexible and robust to think and include people with disabilities.

39:00 – Guest mentions larger buttons.

40:52 – Panelists and Guest talk back-and-forth.

42:22 – Chris: It’s an accessibility and inclusivity element. I saw a dropdown menu and worked great on certain devices but not others. I could beat this horse all day long but the whole: what happens of the JavaScript file doesn’t load or just accordion options?

43:50 – Guest: It’s the progressive enhancement element.

44:05 – Guest: I think it’s worth noting. I think these things dovetail really nicely.

46:29 – Chris: Did you do a video interview, Aimee, talking about CSS? Is CSS better than JavaScript in some ways I don’t know if this is related or not?

47:03 – Aimee: When I talk about JavaScript vs. CSS...the browser optimizes those.

47:27 – Aimee: But as someone who loves JavaScript...and then some very talented people taught me that you have to find the right tool for the job.

47:29 – Guest: I am the other way around – interesting.

JSJ 409: Swagger and Open API with Josh Ponelat

Today the panel discusses the difference between Swagger and Open API with Josh Ponelat. Josh details the difference between the two. Swagger is a set of protocols around describing restful APIs. Swagger was taken over by a company called SmartBear, who donated the donated the specification to the Open Linux Foundation, and that became the Open API. Swagger is the tooling surrounding these specifications. Open API is a standardized way to describe a restful API in a YAML file. Once you’ve got a YAML file to describe your API, you can use tooling like Swagger to leverage that and take it to the next level. Using the Open API process is useful for situations where you already have an API in place, but want to codify and document it so that it’s controlled. Then going forward, you won’t introduce contradictions and it remains consistent because it’s documented in a YAML file. The process leaves room for enhancement in the future as well. 

Josh talks about some of the benefits of standardizing your API and some of the use cases besides tooling. A standardized API can help show developers how to use your API, SDKs, and service stubs by knowing your API is consistent in style. This makes it easier to find breaking changes and more. Josh talks more about Swagger, a finite set of tooling around Open API, most of which are open source. He talks about other tools that test APIs and do linting on YAML files. Some of the companies that use Open API include Google, Amazon, and Microsoft. Josh talks about how Amazon implements Open API.

Josh talks about the book he’s writing, Designing APIs with Swagger and Open API. The book goes over describing APIs today, how to design APIs without writing code first, and how to get the most out of the system. The show concludes with Josh talking about the power of consistency and writing things down on paper. He discusses where implications that the standardization of APIs has on the text industry.
