Start to build real projects. Stay curious! Move forth and back between JavaScript and React while you learn React. However, modern JavaScript is capable of dealing with all the things itself. Hence my recommendation: As alternative, try to migrate the code from jQuery to React instead as a learning opportunity.

Instead I focused on the journey ahead with Angular which then became React. Why do you want to learn React in the first place? They may only know that they are in huge demand by companies and jobs.

Frequently asked questions

However, sometimes it makes sense to backpedal to the question: Why do I need this? What problem does it solve for me? Too often people throw libraries on top of their tech stack without experiencing the problem in the first place.

It demonstrates you which problem the new library is solving for you. The same technique can be applied when deciding whether you want to learn React or another solution such as Vue or Angular. Build a basic application with the solutions of your choice and compare your the development experience. Which of the solutions felt just right for you?

I strongly believe the best start is going through the official React documentation. The documentation keeps up with the recent changes, is not biased, teaches you everything the React way, and is put together by the React core team and the React community in your interest.

Being referred to the documentation of a library as a beginner in web development can be intimidating. On your career path to becoming a developer, you will get used to learn new things with the documentation of the new thing, so why not get used to it now?

It comes with certain benefits to learn documentation driven:. From there, I can always check for other learning material, but my starting point will always be the official documentation of the new thing I intend to learn.

After you went through the React beginner tutorial from the React documentation and learned the basics of React from scratch, continue learning by building a project yourself before learning any other tech.

For instance, there are also people who want to learn React by building games.

I guess you will find plenty of React Tic Tac Toe implementations out there. Implement the game in React yourself and compare your solution to the other solutions. You will learn from your mistakes and learn to evaluate your source code against the implementation by others.

Learn React by doing is one of the most common recommendations you will get to hear from other developers, it applies to almost everything in life, because every task will present you with a new challenge to grow as a React developer. Also it is too easy to passively consume video courses, books, and tutorials. Get your hands dirty and implement something yourself.

Get stuck with a problem, become desperate, ponder over the problem by taking time off the screen, solve the problem eventually, and reap the fruits of it. Confront yourself to stick to coding every day. You can participate in the Days of Code challenge, write about it on Twitter or on your website. Make it a daily habit. Only when sticking to it for a while, by having the persistence and by coding every day, you will eventually become a React developer. The best way to learn something new is to learn it in public.

Confront yourself with the feedback from other React developers by showing off your achievements. If you have reached a milestone with your React project, show it to others and ask for their feedback.

These are a couple of commonly known platforms to share ideas around React:. You will not only get feedback from people there, but also dive more into React by joining discussions. Be part of the community. Another great way to learn something new yourself is to explain it to someone else.

Maybe you are one step ahead of a fellow React beginner and can help them out. Checkout the React Beginner Thread in the React Subreddit where you can help fellow React developers to solve their problems. React has only a slim API surface area, so try to get proficient with it. Learn and understand React. Learn React in depth by applying your learned skills in your project and not by consuming endless of content. How to get started with actual coding a React project?

Play around with React and checkout whether you like it.

However, if you want to learn how to develop React applications on your local machine, checkout these MacOS and Windows Setup Guides to make it work on your machine:. These are a few essential of them that will not go away that quickly:. Being equipped with these advanced React techniques, you should be comfortable to dive into larger React applications where you will find these concepts and techniques more often.

Due to React Hooks, the other Higher-Order Components and Render Prop Components may be less used in the future, but you should still see them fairly often throughout the next year.

Note that I mention this very late in this guide, because often React beginners are stuck in a never ending story of just consuming content to learn React. The thing I want to point out: Start to produce by developing React applications yourself or by writing about your learnings.

Learning by doing is the key here. Every problem along the way can be looked up online. And then if you want to learn more about React, checkout all the other resources to learn React online.

My recommendation is to not only consume one kind of learning material, but to diversify your learning resources:. However, not every kind of learning material may suit you. The same applies to the teaching styles of the people behind the larning material. Everyone has a different way to produce content and to offer it to their students, so checkout which teaching style is best for you.

However, I found myself getting quite lost after just a few videos. The teacher in that highly rated series kept it easy at first but then blindsides you with hard to grasp concepts and code and failed to inform well what was going on. If you are into reading, checkout online tutorials and React books. Print books are a good resources to learn React offline as well.

To achieve the goals stated in the first paragraph, we have to consider the critical file size budget for JavaScript. Opinions vary on what that budget should be and it heavily depends on the nature of your project , but a budget of KB JavaScript gzipped already would take up to 1s to parse and compile on an average phone.

On a middle-class mobile device, that accounts for seconds for Time-To-Interactive. We could also go beyond the bundle size budget though. Tools such as Calibre , SpeedCurve and Bundlesize can help you keep your budgets in check, and can be integrated into your build process.

Performance budgets should adapt depending on the network conditions for an average mobile device. Stick to your environment for building, be it Grunt, Gulp, Webpack, Parcel, or a combination of tools. Among the build tools, Webpack seems to be the most established one, with literally hundreds of plugins available to optimize the size of your builds.

Getting started with Webpack can be tough though.

Both of them are great introductions for diving into Webpack. Webpack Fundamentals is a very comprehensive 4h course with Sean Larkin, released by FrontendMasters. Webpack examples has hundreds of ready-to-use Webpack configurations, categorized by topic and purpose. Bonus: there is also a Webpack config configurator that generates a basic configuration file. Use progressive enhancement as a default. Keeping progressive enhancement as the guiding principle of your front-end architecture and deployment is a safe bet.

Design and build the core experience first, and then enhance the experience with advanced features for capable browsers, creating resilient experiences. If your website runs fast on a slow machine with a poor screen in a poor browser on a sub-optimal network, then it will only run faster on a fast machine with a good browser on a decent network.

Choose a strong performance baseline. With the performance bottlenecks moving away from the server to the client , as developers, we have to consider all of these unknowns in much more detail. The first render tends to warm up a bunch of lazily compiled code, which a larger tree can benefit from when it scales. The second render is basically an emulation of how code reuse on a page affects the performance characteristics as the page grows in complexity.

Evaluate each framework and each dependency. Now, not every project needs a framework and not every page of a single-page-application needs to load a framework. It might sound obvious but worth stating: some projects can also benefit benefit from removing an existing framework altogether. Inian Parameshwaran has measured performance footprint of top 50 frameworks against First Contentful Paint — the time from navigation to the time when the browser renders the first bit of content from the DOM.

You could examine your framework candidates and the proposed architecture, and study how most solutions out there perform, e. Baseline performance cost matters. According to a study by Ankur Sethi , "your React application will never load faster than about 1.

Your Angular app will always take at least 2. The users of your Vue app will need to wait at least 1 second before they can start using it. In exchange, your team gains maintainability and developer efficiency, of course. But this consideration needs to be deliberate. A good starting point is to choose a good default stack for your application. When building a web app, look into the PRPL pattern and application shell architecture. The idea is quite straightforward: Push the minimal code needed to get interactive for the initial route to render quickly, then use service worker for caching and pre-caching resources and then lazy-load routes that you need, asynchronously.

PRPL stands for Pushing critical resource, Rendering initial route, Pre-caching remaining routes and Lazy-loading remaining routes on demand. Have you optimized the performance of your APIs? APIs are communication channels for an application to expose data to internal and third-party applications via so-called endpoints.

When designing and building an API , we need a reasonable protocol to enable the communication between the server and third-party requests. Representational State Transfer REST is a well-established, logical choice: it defines a set of constraints that developers follow to make content accessible in a performant, reliable and scalable fashion. As with good ol' HTTP requests, when data is retrieved from an API, any delay in server response will propagate to the end user, hence delaying rendering.

When a resource wants to retrieve some data from an API, it will need to request the data from the corresponding endpoint. A component that renders data from several resources, such as an article with comments and author photos in each comment, may need several roundtrips to the server to fetch all the data before it can be rendered.

Furthermore, the amount of data returned through REST is often more than what is needed to render that component.

GraphQL provides a performant solution to these issues. Per se, GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data.

In addition, because GraphQL is using schema metadata that tells how the data is structured , it can already organize data into the preferred structure, so, for example, with GraphQL, we could remove JavaScript code used for dealing with state management , producing a cleaner application code that runs faster on the client.

You can achieve good performance without them, but AMP does provide a solid performance framework with a free content delivery network CDN , while Instant Articles will boost your visibility and performance on Facebook. For content-heavy websites that are dealing with a lot of third-party content, these options could potentially help speed up render times dramatically.

Unless they don't. AMP is not what makes the biggest difference from a performance perspective. Obviously, a presence in a walled garden places developers in a position to produce and maintain a separate version of their content, and in case of Instant Articles and Apple News without actual URLs thanks Addy, Jeremy! Choose your CDN wisely.

Depending on how much dynamic data you have, you might be able to "outsource" some part of the content to a static site generator , pushing it to a CDN and serving a static version from it, thus avoiding database requests.

You could even choose a static-hosting platform based on a CDN, enriching your pages with interactive components as enhancements JAMStack. In fact, some of those generators like Gatsby on top of React are actually website compilers with many automated optimizations provided out of the box.

As compilers add optimizations over time, the compiled output gets smaller and faster over time. Notice that CDNs can serve and offload dynamic content as well. So, restricting your CDN to static assets is not necessary.

Double-check whether your CDN performs compression and conversion e. Assets Optimizations Use Brotli or Zopfli for plain text compression. In , Google introduced Brotli , a new open-source lossless data format, which is now supported in all modern browsers. In practice, Brotli appears to be much more effective than Gzip and Deflate. It might be very slow to compress, depending on the settings, but slower compression will ultimately lead to higher compression rates.

Still, it decompresses fast. You can also estimate Brotli compression savings for your site. At the highest level of compression, Brotli is so slow that any potential gains in file size could be nullified by the amount of time it takes for the server to begin sending the response as it waits to dynamically compress the asset.

With static compression, however, higher compression settings are preferred. The catch is that files will take around 80 times longer to compress.

The strategy? Make sure that the server handles content negotiation for Brotli or gzip properly. Use responsive images and WebP. Ire Aderinokun has a very detailed tutorial on converting images to WebP , too.A sample output by imaging-heap , a command line tool that measure the efficiency across viewport sizes and device pixel ratios.

Instead I focused on the journey ahead with Angular which then became React. Create Calculator. In comparison to other frontend solutions, React makes heavily use of JavaScript. Modules are very cool, because they let you encapsulate all sorts of functionality, and expose this functionality to other JavaScript files, as libraries. In , Google introduced Brotli , a new open-source lossless data format, which is now supported in all modern browsers.
