ai JSJ 329: Promises, Promise.finally(), and Async/await with Valeri Karpov By devchat.tv Published On :: Tue, 04 Sep 2018 06:00:00 -0400 Panel: Charles Max Wood AJ O’Neal Aimee Knight Special Guests: Valeri Karpov In this episode, the panel talks with programmer, Valerie Karpov from Miami, Florida. He is quite knowledgeable with many different programs, but today’s episode they talk specifically about Async/Await and Promise Generators. Val is constantly busy through his different endeavors and recently finished his e-book, “Mastering Async/Await.” Check-out Val’s social media profiles through LinkedIn, GitHub, Twitter, and more. Show Topics: 1:20 – Val has been on previous episodes back in 2013 & 2016. 1:37 – Val’s background. He is very involved with multiple companies. Go checkout his new book! 2:39 – Promises generators. Understand Promises and how things sync with Promises. Val suggests that listeners have an integrated understanding of issues like error handling. 3:57 – Chuck asks a question. 6:25 – Aimee’s asks a question: “Can you speak to why someone would want to use Async/Await?” 8:53 – AJ makes comments. 10:09 – “What makes an Async/Await not functional?” – Val 10:59 – “What’s wrong with Promises or Async/Await that people don’t like it?” - AJ 11:25 – Val states that he doesn’t think there really is anything wrong with these programs it just depends on what you need it for. He thinks that having both gives the user great power. 12:21 – AJ’s background is with Node and the Python among other programs. 12:55 – Implementing Complex Business Logic. 15:50 – Val discusses his new e-book. 17:08 – Question from Aimee. 17:16 – AJ answers question. Promises should have been primitive when it was designed or somewhat event handling. 17:46 – The panel agrees that anything is better than Call Backs. 18:18 – Aimee makes comments about Async/Await. 20:08 – “What are the core principles of your new e-book?” – Chuck 20:17 – There are 4 chapters and Val discusses, in detail, what’s in each chapter. 22:40 – There could be some confusion from JavaScript for someone where this is their first language. Does Async/Await have any affect on the way you program or does anything make it less or more confusing in the background changes? 24:30 – Val answers the before-mentioned question. Async/Await does not have anyway to help with this (data changes in the background). 25:36 – “My procedural code, I know that things won’t change on me because it is procedural code. Is it hard to adjust to that?” – AJ 26:01 – Val answers the question. 26:32 – Building a webserver with Python. 27:31 – Aimee asks a question: “Do you think that there are cases in code base, where I would want to use Promises? Not from a user’s perspective, but what our preferences are, but actual performance. Is there a reason why I would want to use both or be consistent across the board?” 28:17 – Val asks for some clarification to Aimee’s question. 29:14 – Aimee: “My own personal preference is consistency. Would I want to use Promises in ‘x’ scenario and/or use Async/Await in another situation?” 32:28 – Val and AJ are discussing and problem solving different situations that these programs 33:05 – “When would you not want to use Async/Await?” – AJ 33:25 – Val goes through the different situations when he would not use Async/Await. 33:44 – Chuck is curious about other features of Async/Await and asks Val. 36:40 – Facebook’s Regenerator 37:11 – AJ: “Back in the day, people would be really concerned with JavaScript’s performance even with Chrome.” He continues his thoughts on this topic. 38:11 – Val answers the AJ’s question. 39:10 – Duck JS probably won’t include generators. 41:18 – Val: “Have anyone used Engine Script before?” The rest of the panel had never heard of this before. 42:09 – Windows Scripting Host 42:56 – Val used Rhino in the past. 43:40 – Val: “Going back to the web performance question...” 47:08 – “Where do you see using Async/Await the most?” – Chuck 47:55 – Val uses Async/Await for everything on the backend because it has made everything so easy for him. 48:23 – “So this is why you really haven’t used Web Pack?” – AJ 49:20 – Let’s go to Aimee’s Picks! 50:18 – AJ’s story, first, before we get to Promises. 54:44 – Let’s transition to Promises Finally. 54:53 – Val talks about Promises Finally. 59:20 – Picks Links: JavaScript Valeri Karpov’s GitHub Valeri Karpov’s Twitter Valeri Karpov’s LinkedIn New E-Book: Mastering Async/Await Node Python Windows Scripting Host Facebook’s Regenerator Rhino Sponsors: Kendo UI Sentry Digital Ocean Picks: Charles YouTube Video “IKEA” by Coulton Conference Amazon Prime Day Aimee Blog Post Article AJ IKEA https://ppl.family Val https://www.npmjs.com/package/serve http://bit.ly/ultimate-skiing http://asyncawait.net/jsjabber New E-Book: Mastering Async/Await Full Article
ai JSJ 331: “An Overview of JavaScript Testing in 2018” with Vitali Zaidman By devchat.tv Published On :: Tue, 18 Sep 2018 06:00:00 -0400 Panel: AJ O’Neal Aimee Knight Joe Eames Charles Max Wood Special Guests: Vitali Zaidman In this episode, the panel talks with programmer, Vitali Zaidman, who is working with Software Solutions Company. He researches technologies and starts new projects all the time, and looks at these new technologies within the market. The panel talks about testing JavaScript in 2018 and Jest. Show Topics: 1:32 – Chuck: Let’s talk about testing JavaScript in 2018. 1:53 – Vitali talks about solving problems in JavaScript. 2:46 – Chuck asks Vitali a question. 3:03 – Vitali’s answer. 3:30 – Why Jest? Why not Mocha or these other programs? 3:49 – Jest is the best interruption of what testing should look like and the best practice nowadays. There are different options, they can be better, but Jest has this great support from their community. There are great new features. 4:31 – Chuck to Joe: What are you using for testing nowadays? 4:43 – Joe: I use Angular, primarily. 6:01 – Like life, it’s sometimes easier to use things that make things very valuable. 7:55 – Aimee: I have heard great things about Cypress, but at work we are using another program. 8:22 – Vitali: Check out my article. 8:51 – Aimee: There are too many problems with the program that we use at work. 9:39 – Panelist to Vitali: I read your article, and I am a fan. Why do you pick Test Café over Cypress, and how familiar are you with Cypress? What about Selenium and other programs? 10:12 – Vitali: “Test Café and Cypress are competing head-to-head.” Listen to Vitali’s suggestions and comments per the panelists’ question at this timestamp. 11:25 – Chuck: I see that you use sign-on... 12:29 – Aimee: Can you talk about Puppeteer? It seems promising. 12:45 – Vitali: Yes, Puppeteer is promising. It’s developed by Google and by Chrome. You don’t want to use all of your tests in Puppeteer, because it will be really hard to do in other browsers. 13:26: Panelist: “...5, 6, 7, years ago it was important of any kind of JavaScript testing you had no idea if it worked in one browser and it not necessarily works in another browser. That was 10 years ago. Is multiple browsers testing as important then as it is now? 14:51: Vitali answers the above question. 15:30 – Aimee: If it is more JavaScript heavy then it could possibly cause more problems. 15:56 – Panelist: I agree with this. 16:02 – Vitali continues this conversation with additional comments. 16:17 – Aimee: “I see that Safari is the new Internet Explorer.” 16:23: Chuck: “Yes, you have to know your audience. Are they using older browsers? What is the compatibility?” 17:01 – Vitali: There are issues with the security. Firefox has a feature of tracking protection; something like that. 17:33 – Question to Vitali by Panelist. 17:55 – Vitali answers the question. 18:30 – Panelist makes additional comments. 18:43 – If you use Safari, you reap what you sow. 18:49 – Chuck: I use Chrome on my iPhone. (Aimee does, too.) Sometimes I wind up in Safari by accident. 19:38 – Panelist makes comments. 19:52 – Vitali tells a funny story that relates to this topic. 20:45 – There are too many standards out there. 21:05 – Aimee makes comments. 21:08 – Brutalist Web Design. Some guy has this site – Brutalist Web Design – where he says use basic stuff and stop being so custom. Stop using the web as some crazy platform, and if your site is a website that can be scrolled through, that’s great. It needs to be just enough for people to see your content. 22:16 – Aimee makes additional comments about this topic of Brutalist Web Design. 22:35 – Panelist: I like it when people go out and say things like that. 22:45 – Here is the point, though. There is a difference between a website and a web application. Really the purpose is to read an article. 23:37 – Vitali chimes in. 24:01 – Back to the topic of content on websites. 25:17 – Panelist: Medium is very minimal. Medium doesn’t feel like an application. 26:10 – Is the website easy enough for the user to scroll through and get the content like they want to? 26:19 – Advertisement. 27:22 – See how far off the topic we got? 27:31 – These are my favorite conversations to have. 27:39 – Vitali: Let’s talk about how my article got so popular. It’s an interesting thing, I started researching “testing” for my company. We wanted to implement one of the testing tools. Instead of creating a presentation, I would write first about it in Medium to get feedback from the community as well. It was a great decision, because I got a lot of comments back. I enjoyed the experience, too. Just write about your problem in Medium to see what people say. 28:48 – Panelist: You put a ton of time and energy in this article. There are tons of links. Did you really go through all of those articles? 29:10 – Yes, what are the most permanent tools? I was just reading through a lot of comments and feedback from people. I tested the tools myself, too! 29:37 – Panelist: You broke down the article, and it’s a 22-minute read. 30:09 – Vitali: I wrote the article for my company, and they ad to read it. 30:24 – Panelist: Spending so much time – you probably felt like it was apart of your job. 30:39 – Vitali: I really like creating and writing. It was rally amazing for me and a great experience. I feel like I am talented in this area because I write well and fast. I wanted to express myself. 31:17 – Did you edit and review? 31:23 – Vitali: I wrote it by myself and some friends read it. There were serious mistakes, and that’s okay I am not afraid of mistakes. This way you get feedback. 32:10 – Chuck: “Some people see testing in JavaScript, and people look at this and say there are so much here. Is there a place where people can start, so that way they don’t’ get too overwhelmed? Is there a way to ease into this and take a bite-size at a time?” 32:52 – Vitali: “Find something that works for them. Read the article and start writing code.” He continues this conversation from here on out. 34:03 – Chuck continues to ask questions and add other comments. 34:16 – Vitali chimes-in. 34:38 – Chuck. 34:46 – Vitali piggybacks off of Chuck’s comments. 36:14 – Panelist: Let’s go back to Jest. There is a very common occurrence where we see lots of turn and we see ideas like this has become the dominant or the standard, a lot of people talk about stuff within this community. Then we get this idea that ‘this is the only thing that is happening.’ Transition to jQuery to React to... With that context do you feel like Jest will be a dominant program? Are we going to see Jest used just as common as Mocha and other popular programs? 38:15 – Vitali comments on the panelist’s question. 38:50 – Panelist: New features. Are the features in Jest (over Jasmine, Mocha, etc.) so important that it will drive people to it by itself? 40:30 – Vitali comments on this great question. 40:58 – Panelist asks questions about features about Jest. 41:29 – Vitali talks about this topic. 42:14 – Let’s go to picks! 42:14 – Advertisement.

ai JSJ 398: Node 12 with Paige Niedringhaus By devchat.tv Published On :: Tue, 08 Oct 2019 06:00:00 -0400 Guest Paige Niedringhaus has been a developer full time for 3 years, and today she is here to talk about Node 12. One of the things she is most excited about is the ES6 support that is now available, so things that used to require React, Angular, or Vue can now be done in Node. The require function will not have to be used in Node 12. AJ is worried about some of these changes and expresses his concerns. Paige assures him that in the beginning you won’t have to switch things to imports. You may have to change file extensions/types so Node can pick up what it’s supposed to be using. They are also trying to make it compatible with CommonJS. Node 12 also boasts an improved startup time. The panel discusses what specifically this means. They talk about the code cache and how Node caches the built in libraries that it comes prepackaged with. The V8 engine is also getting many performance enhancements. Paige talks about the shift from promises to async. In Node 12, async functions will actually be faster than promises. They discuss some of the difficulties they’ve had in the past with Async08, and especially callbacks. Another feature of Node 12 is better security. The transcripted security layer (TLS), which is how Node handles encrypted strains of communication, is upgrading to 1.3. The protocol is simpler to implement, quicker to negotiate sessions between the applications, provides increased end user privacy, and reduces request time. Overall, this means less latency for everybody. 1.3 also gets rid of the edge cases that caused TLS to be way far slower than it needed to be. The conversation turns to properly configuring default heap limits to prevent an ‘out of memory’ error. Configuring heap limits is something necessary when constructing an incredibly large object or array of objects. Node 12 also offers formatted diagnostic summaries, which can include information on total memory, used memory, memory limits, and environment lags. It can report on uncaught exceptions and fatal errors. Overall, Node 12 is trying to help with the debugging process. They talk about the different parsers available and how issues with key pairing in Node have been solved. Paige talks about using worker threads in Node 12. Worker threads are really beneficial for CPU intensive JavaScript operations. Worker threads are there for those things that eat up all of your memory, they can alleviate the load and keep your program running efficiently while doing their own operations on the sideline, and returning to the main thread once they’ve finished their job. None of the panelists have really used worker threads, so they discuss why that is and how they might use Worker Threads in Node 12. In addition, Node 12 is making Native module creation and support easier, as well as all the different binaries a node developer would want to support. Paige makes it a point to mention the new compiler and minimum platform standards. They are as follows: GCC minimum 6 GLIVC minimum 2.17 on platforms other than Mac and Windows (Linux) Mac users need at least 8 and Mac OS 10.10 If you’ve been running node 11 builds in Windows, you’re up to speed Linux binaries supported are Enterprise Linux 7, Debian 8, and Ubuntu 14.04 If you have different requirements, go to the Node website Panelists J.C.

ai JSJ 399: Debugging with Async/Await with Valeri Karpov By devchat.tv Published On :: Thu, 10 Oct 2019 06:00:00 -0400 Valeri Karpov is a maintainer on Mongoose, has started a few companies, and works for a company called Booster Fuels. Today’s topic debugging with Async/Await. The panel talks about some of the challenges of debugging with Async. AJ, however, has never encountered the same problems, so he shares his debugging method. Valeri differentiates between .catch vs try...catch, and talks about why he prefers .catch. There are two ways to handle all errors in an async function without leading to an unhandled promise rejection. The first is to wrap the entire body of the async function in a try...catch, has some limitations. Calling an async function always returns a promise, so the other approach is calling .catch on the promise to handle any errors that occur in that function body. One of the key differences is if you return a promise within an async function, and that return promise is wrapped in a try...catch, the catch block won’t get called if that promise is rejected, whereas if you call .catch on the promise that the function returns, you’ll actually catch that error. There are rare instances where this can get tricky and unintuitive, such as where you have to call new promise and have resolve and reject, and you can get unexpected behavior. The panel discusses Valeri’s current favorite JS interview question, which is, “Given a stream, implement a function called ‘stream to promise’ that, given a stream, returns a promise that resolves to the concatenation of all the data chunks emitted by the stream, or rejects if the stream emits an error event.” It’s really simple to get this qustion right, and really simple to get it wrong, and the difference can be catastrophic. AJ cautions listeners to never use the data event except in the cases Val was talking about, only use the readable event. The conversation turns to the function of a readable event. Since data always pushes data, when you get a readable event, it’s up to you to call read inside the function handler, and then you get back a chunk of data, call read again and again until the read returns null. When you use readable, you are in control and you avoid piling functions into RAM. In addition, the right function will return true or false to let you know if the buffer is full or not. This is a way to mix imperative style into a stream. The next discussion topics are the differences between imperative style and reactive style and how a waits and promises work in a normal four loop. A wait suspends the execution of a function until the promise is resolved. Does a wait actually stop the loop or is it just transpiling like a promise and it doesn’t stop the loop. AJ wrote a module called Batch Async to be not as greedy as promise.all but not as limited as other options. The JavaScript panelists talk about different async iterators they’ve used, such as Babel. They discuss the merits of Babel, especially since baseline Android phones (which a significant portion of the population of the world uses) run UC Browser that doesn’t support Babel, and so a significant chunk of the population of the world. On the other hand, if you want to target a large audience, you need to use Babel. Since frameworks in general don’t handle async very well, the panel discusses ways to mitigate this. They talk about different frameworks like Vue, React, and Express and how they support async functions. They discuss why there is no way for you to actually cancel an async option in an actual case, how complex canceling is, and what you are really trying to solve for in the cancellation process. Canceling something is a complex problem. Valeri talks about his one case where he had a specific bug that required non-generic engineering to solve, and cancelling actually solved something. When AJ has come across cancellation issues, it’s very specific to that use case. The rest of the panelists talk about their experiences with having to cancel something. Finally, they talk about their experience with async generator functions. A generator is a function that lets you enter into the function later. This makes sense for very large or long running data sets, but when you have a bounded items, don’t complicate your code this way. When an async generator function yields, you explicitly need to call next in order for it to pick up again. If you don’t call ‘next’, it’s essentially cancelled. Remember that object.keys and object.values are your friends.

ai JSJ 401: Hasura with Tanmai Gopal By devchat.tv Published On :: Thu, 17 Oct 2019 06:00:00 -0400 Tanmai is one of the founders at Hasura. Hasura gives you instant graphQL APIs on top of a Postgres database. The eventual idea is to make data access secure and easy. Tanmai explains the challenges of doing this in the cloud. He talks about some of the difficulties with the tooling around using GraphQL and its bias towards working well with a monolith. Since GraphQL is basically a shared type system that describes your API, that means all your types need to be in the same code base. This is at odds with the folks who want to do microservices and serverless functions, because since their API is split across multiple services they have different types, and forcing these types to work together defeats the purpose of using microservices. Also, storing state across requests doesn’t work well with serverless and cloud native stuff. In short, learning to live without state is one of the general challenges with going serverless. This is where Hasura comes into play, and Tanmai explains how it works. Hasura is metadata driven, and each instance of the server can leverage multiple calls and exhibit a high amount of concurrency. It’s designed to be a little more CPU bound than memory bound, which means that configuring auto scaling on it is very easy and allows you to utilize the elasticity of cloud native applications. Tanmai clarifies his usage of the word ‘cloud native’, by which he means microservices. He explains that when you have a metadata based engine, this metadata has a language that allows you to bring to bring in types from multiple upstream microservices, and create a coherent graphQL API on top of that. Hasura is a middle man between the microservices and the consumer that converts multiple types into a single coherent graphQL API. Next, Tanmai explains how Hasura handles data fetching and a high volume of requests. They also invented PostgresQL, RLS-like semantics within Hasura. He explains the process for merging your microservices into a single graphQL interface. Back on data fetching, Tanmai explains that when the product is an app, preventing an overabundance of queries becomes easier because during one of the staging processes that they have, they extract all of the queries that the app is actually making, and in the production version it only allows the queries that it has seen before. Hasura is focused on both the public interface and private use cases, though private is slightly better supported. Tanmai talks about the customizations available with Hasura. Hasura supports two layers. One is an aliasing layer that lets you rename tables, columns, etc as exposed by PostgresQL. The other is a computer column, so that you can add computer columns so you can extend the type that you get from a data model, and then you can point that to something that you derive. The panelist discusses the common conception of why it is a bad idea to expose the data models to the frontend folks directly. They discuss the trend of ‘dumbing down’ available tooling to appeal to junior developers, at the cost of making the backend more complicated. They talk about some of the issues that come from this, and the importance of tooling to solve this concern. Finally, Tanmai talks about the reasons to use Hasura over other products. There are 2 technologies that help with integrating arbitrary data sources. First is authorization grammar, their version of RLS that can extend to any system of types and relationships, The second is the data wrapper, part of the compiler that compiles from the graphQL metadata AST to the actual SQL AST. That is a generic interface, so anyone can come in and plug in a Haskell module that has that interface and implement a backend compiler for a native query language. This allows us to plug in other sources and stitch microservices together. The show concludes with Tanmai talking about their choice to use Haskell to make Hasura.

ai JSJ 402: SEO for Developers with Vitali Zaidman By devchat.tv Published On :: Tue, 22 Oct 2019 06:00:00 -0400 Vitali Zaidman is a full stack developer who works for WellDone Software Solutions and is currently working on a SEO project. Today’s show is about SEO for developers. SEO stands for search engine optimization, which helps your website appear higher on search engines. SEO has changed a lot in the past 10 years. It has become much more regulated, and the “dirty tricks” of the past will actually penalize you, so it is important to do it properly. Today the best way to promote yourself on Google besides making good content is for developers to optimize the content, make it small, operational, secure, accessible, and operate on mobile. Much of it goes back to using semantic HTML since Google looks at it before looking at the structure of your website, how valuable it is, and how users interact with it. Having good semantics helps Google determine how valuable it is, so semantic HTML should be a top priority. Semantic HTML can also make your site more accessible to users, which will in turn give you a larger audience. The panel talks about some of the challenges of SEO faced by companies. While bigger companies have the privilege of dedicated SEO teams, small companies often lack these specialists. Thankfully, Google has made their guidelines for SEO very accessible and gives you a lot of tools to track your optimization. The panel talks about different methods of SEO, such as including FAQ at the bottom of the web page, optimizing page speed, and image optimization. Structured data like questions and answers enriches the data that is shown for users on the search results page. To score your website’s SEO, Google released the tool PageSpeed Insights, which will assign your website a performance score. Google uses two main tools to track a website’s SEO. First, they use real field data. If you opt in to ‘help improve Chrome’s features and performance’ when you install Chrome, it tracks how fast websites load on your Chrome, and they collect this information to understand how webpages load. It is required that your website has a certain amount of visitors to be tracked and added to the database. Second, Google has their own devices that will check your website. Currently, they are using a Moto G4 to test for mobile access, and a slow internet connection. Because of this, it is pretty easy to get a good score on desktop, but difficult to get a good score on mobile. The technology that drives all this is called Lighthouse. Overall, performance is the main thing users look for, so aim for good performance and fast websites. The panel discusses the correlation between performance and SEO. For example, Fox News and CNN are two of the top search results for ‘news’, but they have a dismal Google PSI score. They conclude that performance shouldn’t be ignored, but be careful about directly correlating performance and SEO. They also caution against getting obsessed over certain aspects of SEO by themselves.

ai JSJ 418: Security Scary Stories and How to Avoid Them with Kevin A McGrail By devchat.tv Published On :: Tue, 28 Jan 2020 06:00:00 -0500 In this episode of JavaScript Jabber the panel interviews security expert, Kevin A. McGrail. He starts by explaining what security frameworks and what they do. The panel wonders how to know if your developers are capable of self-auditing your security or if you need help. Kevin shares recommendations for companies to look at to answer that question. Aimee Knight explains the hell she has been in making changes to be compliant with CCPA. The panel considers how policies like this complicate security, are nearly impossible to be compliant with and how they can be weaponized. They discuss the need for technical people to be involved in writing these laws. Kevin explains how you can know how secure your systems actually are. He shares the culture of security first he tries to instill in the companies he trains. He also trains them on how to think like a bad guy and explains how this helps developers become security first developers. The panel discusses how scams have evolved and how the same scams are still being run. They consider the importance of automated training and teaching developers to do it right the first time. Finally, they consider the different ways of authentication, passwords, passphrases, sim card, biometrics. Kevin warns against oversharing or announcing vacations. The panel discusses real-world tactics bad guys use. Kevin explains what he trains people to do and look out for to increase security with both social engineering and technical expertise.
