To share upcoming changes with our partners in the React ecosystem, we’re establishing official prerelease channels. We hope this process will help us make changes to React with confidence, and give developers the opportunity to try out experimental features.

This post will be most relevant to developers who work on frameworks, libraries, or developer tooling. Developers who use React primarily to build user-facing applications should not need to worry about our prerelease channels.

React relies on a thriving open source community to file bug reports, open pull requests, and submit RFCs. To encourage feedback, we sometimes share special builds of React that include unreleased features.

Because the source of truth for React is our public GitHub repository, it’s always been possible to build a copy of React that includes the latest changes. However it’s much easier for developers to install React from npm, so we occasionally publish prerelease builds to the npm registry. A recent example is the 16.7 alpha, which included an early version of the Hooks API.

We would like to make it even easier for developers to test prerelease builds of React, so we’re formalizing our process with three separate release channels.

Release Channels

The information in this post is also available on our Release Channels page. We will update that document whenever there are changes to our release process.

Each of React’s release channels is designed for a distinct use case:

• Latest is for stable, semver React releases. It’s what you get when you install React from npm. This is the channel you’re already using today. Use this for all user-facing React applications.
• Next tracks the master branch of the React source code repository. Think of these as release candidates for the next minor semver release. Use this for integration testing between React and third party projects.
• Experimental includes experimental APIs and features that aren’t available in the stable releases. These also track the master branch, but with additional feature flags turned on. Use this to try out upcoming features before they are released.

All releases are published to npm, but only Latest uses semantic versioning. Prereleases (those in the Next and Experimental channels) have versions generated from a hash of their contents, e.g. 0.0.0-1022ee0ec for Next and 0.0.0-experimental-1022ee0ec for Experimental.

The only officially supported release channel for user-facing applications is Latest. Next and Experimental releases are provided for testing purposes only, and we provide no guarantees that behavior won’t change between releases. They do not follow the semver protocol that we use for releases from Latest.

By publishing prereleases to the same registry that we use for stable releases, we are able to take advantage of the many tools that support the npm workflow, like unpkg and CodeSandbox.

Latest Channel

Latest is the channel used for stable React releases. It corresponds to the latest tag on npm. It is the recommended channel for all React apps that are shipped to real users.

If you’re not sure which channel you should use, it’s Latest. If you’re a React developer, this is what you’re already using.

You can expect updates to Latest to be extremely stable. Versions follow the semantic versioning scheme. Learn more about our commitment to stability and incremental migration in our versioning policy.

Next Channel

The Next channel is a prerelease channel that tracks the master branch of the React repository. We use prereleases in the Next channel as release candidates for the Latest channel. You can think of Next as a superset of Latest that is updated more frequently.

The degree of change between the most recent Next release and the most recent Latest release is approximately the same as you would find between two minor semver releases. However, the Next channel does not conform to semantic versioning. You should expect occasional breaking changes between successive releases in the Next channel.

Do not use prereleases in user-facing applications.

Releases in Next are published with the next tag on npm. Versions are generated from a hash of the build’s contents, e.g. 0.0.0-1022ee0ec.

Using the Next Channel for Integration Testing

The Next channel is designed to support integration testing between React and other projects.

All changes to React go through extensive internal testing before they are released to the public. However, there are myriad environments and configurations used throughout the React ecosystem, and it’s not possible for us to test against every single one.

If you’re the author of a third party React framework, library, developer tool, or similar infrastructure-type project, you can help us keep React stable for your users and the entire React community by periodically running your test suite against the most recent changes. If you’re interested, follow these steps:

• Set up a cron job using your preferred continuous integration platform. Cron jobs are supported by both CircleCI and Travis CI.

• In the cron job, update your React packages to the most recent React release in the Next channel, using next tag on npm. Using the npm cli:

  npm update react@next react-dom@next

  Or yarn:

  yarn upgrade react@next react-dom@next

• Run your test suite against the updated packages.
• If everything passes, great! You can expect that your project will work with the next minor React release.
• If something breaks unexpectedly, please let us know by filing an issue.

A project that uses this workflow is Next.js. (No pun intended! Seriously!) You can refer to their CircleCI configuration as an example.

Experimental Channel

Like Next, the Experimental channel is a prerelease channel that tracks the master branch of the React repository. Unlike Next, Experimental releases include additional features and APIs that are not ready for wider release.

Usually, an update to Next is accompanied by a corresponding update to Experimental. They are based on the same source revision, but are built using a different set of feature flags.

Experimental releases may be significantly different than releases to Next and Latest. Do not use Experimental releases in user-facing applications. You should expect frequent breaking changes between releases in the Experimental channel.

Releases in Experimental are published with the experimental tag on npm. Versions are generated from a hash of the build’s contents, e.g. 0.0.0-experimental-1022ee0ec.

What Goes Into an Experimental Release?

Experimental features are ones that are not ready to be released to the wider public, and may change drastically before they are finalized. Some experiments may never be finalized — the reason we have experiments is to test the viability of proposed changes.

For example, if the Experimental channel had existed when we announced Hooks, we would have released Hooks to the Experimental channel weeks before they were available in Latest.

You may find it valuable to run integration tests against Experimental. This is up to you. However, be advised that Experimental is even less stable than Next. We do not guarantee any stability between Experimental releases.

How Can I Learn More About Experimental Features?

Experimental features may or may not be documented. Usually, experiments aren’t documented until they are close to shipping in Next or Stable.

If a feature is not documented, they may be accompanied by an RFC.

We will post to the React blog when we’re ready to announce new experiments, but that doesn’t mean we will publicize every experiment.

You can always refer to our public GitHub repository’s history for a comprehensive list of changes.

Representational picture

In India, gaming is considered as a hobby and was less than inclined towards gaming from the get- go. But the scenario is slowling changing. Looking at the growth of the industry over the years, we have finally come to a point where families have started being supportive of this career choice. Rather than opting for a 9-to-5 job, more and more gamers have started taking their careers seriously and are transitioning into professional esports athletes and streamers.

So what is gaming? Gaming is a form of entertainment which is consumed via interaction, participation and viewership. It encompasses PC gaming, mobile gaming and console gaming and is multi-billion dollar industry globally. This industry comprises of gamers who can be a casual or an enthusiast, an amateur or a professional, a player or a viewer. Gaming can be as simple as picking up your mobile and launching some birds at hostile pigs in a castle, or as complex as dedicating years to learning and mastering a game and competing against other similarly dedicated players globally with millions of dollars at stake.

The term 'esports' seem new but the concept isn't. Esports is the part of gaming that’s competitive, where various genres of games are played competitively against other players, on different platforms. From fighting against your friend at the local arcade with a barrage of virtual punches and kicks to being seated together and connected to 100s of other gamers and being the last person alive in a perilous deserted island. Esports is as old as gaming is. The only difference we see nowadays, is the higher stakes and the dedication gamers put in to reach the top. With prize pools running in the millions and a loyal audience who travel halfway across the globe to watch their teams play, esports has become a global phenomenon with major brands investing heavily in the industry and corporations building stadiums larger than conventional sports stadiums.

Professional athletes train their body and mind, regularly to stay at the best of conditions and are supported with the state-of-the-art facilities and a salary for playing their game. Another term people might be unfamiliar with is "video game live streaming”. Streaming is a form of online video broadcast on specialised platforms where you play games and entertain your viewers. A viewer might be engrossed by your playstyle or your witty humour. There can be thousands of players watching you at a point of time and cheering for you. Streaming has become a full-time job for a lot of people with them earning a comfortable six-figure income monthly by just regularly entertaining their viewers. Brands sponsor these streamers to advertise and endorse their products on their stream.

The global gaming industry is still growing at a rapid pace with a valuation of $108.9 billion and a YoY growth of 7.8% in 2017. The Asia Pacific region contributes to 47% of this with India ranked 17 th globally valued at $818 million with an 11.14% CAGR. Gaming in India is still nascent with a lot of scope for growth and recognition. Esports plays a huge part in gaming with $696 million market and whopping 385.5 million viewers watching their favourite teams and players fight for glory. That’s thrice as many subscribers Netflix has.

So how far has India come? India is slowly catching up with the rest of the world. We have 253.2 million gamers in India with 81% of them in the age group of 16 – 30. We have professional teams in India who compete globally against other teams. We have people who have taken up streaming as their jobs. Rather than pursuing a regular career like your average John and Jane, we have emerging brave souls who want to stand out and make their dreams come true. And the space is filled with brands who want to work hand in hand with these people, empowering and enabling such a career into reality.

Insight of target audience by COBX games

Gaming in India has been given a boost in the recent years with the advent of 4G and FTTH. Prices have grown more competitive which has helped not only companies but also gamers across India. We have seen a spike in mobile gaming with 4G being introduced in India and will play a major role in the industry. FTTH, which is already being deployed in tier-1 cities, provides high-speed internet connection over optical fibre directly to your home from the ISP which has increased the quality of service. In tier-2 cities, gaming cafés and colleges act as hotspots for gamers and most tournaments are hosted in these colleges, due to the presence of stable infrastructure which, in turn, promotes the growth of gaming.

Esports is on the rise in India with multiple tournaments being announced with unprecedented prize pools. Esports is dynamically changing the industry with numerous brands joining in and helping the space flourish. Monthly tournaments provide a scope for professional gamers to sustain a living and also provides growth to multiple domains attached to esports like cosplayers, shoutcasters, and analysts and so on. From small tournaments in cafés and college labs to huge events filled with gamers, esports has come a long way in India. 2018 saw numerous companies invest heavily in esports by announcing multiple tournaments with prize pools of over Rs 1 crore.

Mujahid Rupani, Co-founder & C.E.O of COBX Gaming says, "We are also expecting an increase in VR and AR gaming in India. VR gears are being readily accessible to people and families are opting in for the virtual reality experience. Mobile phones are growing powerful every day and proving to be effective AR devices. New games are being launched every day which take advantage of augmented reality and taking use experience to a whole new level. Mobile gaming is also on the rise in India due to the ease of entry and affordable and stable internet connection. With the amount of time people invest on mobiles, a lot of developers are shifting their focus to mobile games and catering to a big chunk of gamers who prefer mobiles over expensive PCs and consoles as their gaming gear. With the number of game development studies in our country, the next big title might be from India."

With the ecosystem growing and evolving every year, the future for gaming in India is bright. Gaming in India is an incipient industry and has a long way to go. We hope to see more professional players, more streamers and more parents supporting their kid’s dream. There was a time when you would idolise a sportsperson, the day is here when kids idolise their favourite professional gamer or streamer. We have a generation of parents who are gamers too and encourage their kids and help them balance gaming along with other life priorities. We hope to see more companies and brands invest their time and resource in the gaming industry and maybe one day, a kid who wants to grow up and be a professional gamer.
