ReactJS Roadmap – A Beginners Guide

Reactjs roadmap 2023: In this day and age, the world cannot function without mobile and web applications. Everything has gone digital, from taxi bookings to meal orders to bank transactions. Thanks to well-designed frameworks that ensure a smooth user experience. React is one such powerful frontend library. This ‘what is React’ tutorial will walk you through the basics of the library and show you how to use it with a simple demo.

What Is React?

React is a UI development library based on JavaScript. It is run by Facebook and an open-source developer community. Despite the fact that React is more of a library than a language, it is frequently utilized in web development. The library debuted in May 2013 and has since grown to become one of the most widely used frontend libraries for web development.

React offers various extensions for entire application architectural support, such as Flux and React Native, beyond mere UI.

Now, let’s go through the RoadMap step by step and find out how you can learn the essential skills to become a React Developer in 2022:

Skills You Need To Become React Developer

Roadmap To Become A React Developer in 2022. With the basic knowledge of what react is and what will be your responsibilities as a react developer, let’s move ahead and let you know the essential skills to become a react developer.

1. Basic Skills

Regardless of the library or framework, you want to learn for web development, it is crucial to understand the basics of the web, that is, HTML, CSS and JavaScript.

  • HTML: HTML is the standard for designing documents that will be displayed on the browser. Simply put, it is a language for web pages and helps in creating a website. And to become a react developer, you need to learn the basics, semantic, DOM structuring and section division of pages properly.
  • CSS: CSS is a styling language used for describing the web page presentation. It offers a simple process to add style like colours, spacing, formatting and fonts design to your document. For react development, you need to learn basics, grid, flexbox, media queries and responsive web designs of CSS.
  • JavaScript: JS is a lightweight programming language used for creating network-centric applications.JavaScript corresponds to ECMAScript specification. JS basics you need to learn includes syntax, basic operations, DOM manipulation, hoisting, prototyping, event bubbling, AJAX, and ECMAScript.

2. Common Development Skills

To become a developer, there are a certain number of common skills that you will have to learn, including:

  • GIT (Version Control System)
  • HTTP/HTTPS Protocol
  • Terminal Usage
  • Data Structures & Algorithm
  • Design Patterns
  • Learn GIT

You must absolutely know Git in 2022. Try creating a few repositories on GitHub, share your code with other people, and learn how to download code from Github on your favorite IDE. If you want to learn, then Git Complete: The definitive, step-by-step guide to Git is a great course.

If you need more choices and don’t mind learning from free resources, then you can also explore my list of free courses to learn Git.

  • Know HTTP(S) protocol

If you want to become a web developer, then it’s an absolute must to know HTTP and know it well. I am not asking you to read the specification, but you should at least be familiar with standard HTTP request methods like the GET, POST, PUT, PATCH, DELETE, OPTIONS, and how HTTP/HTTPS works in general.

  • Learn the terminal

Though a frontend developer doesn’t need to learn Linux or terminal, I strongly suggest you get familiar with the terminal, configure your shell (bash, zsh, csh), etc.  If you want to learn terminal and bash, then I suggest you take a look at this Shell Scripting course on Udemy.

If you need more choices, you can also explore my list of free Linux courses for developers.

  • Algorithms and Data Structure

Well, this is again one of the general programming skills which is not necessarily needed for becoming a React developer but absolutely required to become a programmer in the first place.

  • Learn Design Patterns and Software Architecture

Understanding design patterns, like learning algorithms and data structures, isn’t required to become a React Developer, but it will benefit you much. Design patterns are tried-and-true solutions to problems that arise in software development on a regular basis.

Knowing them will help you to find a solution that can withstand the test of time. You can read a few books about design patterns to learn them or join a comprehensive course like Web Application & Software Architecture 101 on Educative, one of the interactive learning websites. 

3. React

You cannot become a react developer without learning to react. So learning the basics as well as every other feature of React thoroughly is critical for anyone who wants to become a React developer. Also, keep in mind to learn to react from the main website of React or any other authorized source with vital information.

4. Build Tools

Build tools are software or programs that automate the creation of executable applications from source code. It converts code into an executable format by linking, compiling, and packaging it. Webpack, package, and Rollup are examples of build tools.

Build tools include package manager and task runners software as well that are listed below:

Package Manager

Task Runner

5. Styling

Learning more about styling will benefit a react developer who will be responsible for the front end of the online application. That’s why you should know how CSS works, its frameworks, and architecture, as well as how to apply it in JavaScript.

A few of the things you should know about CSS for styling are:

CSS Preprocessor

CSS Frameworks

CSS Architecture

CSS in JS

6. State Management

A system’s state is its representation at a specific point in time. It refers to the data in the program that is stored as an array, objects, or strings. As a result, state management is a means of governing a state. The following are the primary components of state management that you should be aware of:

Helpers

i. rematch

ii. reselect

Async Actions

i. Redux Thunk

ii. Redux Better Promise

iii. Redux-Saga

iv. Redux Observable

Data Persistence

i. Redux Persist

ii. Redux Phoenix

7. Type Checkers

The type checker is the process of verifying and enforcing the constraints of types that take place either at compile time or runtime. It ensures that the program is type-safe, i.e, free of any type errors. Some of the basics you should learn to work with type checkers are:

8. Routing

Routing is the method of selecting a path for traffic across networks. For routing in react you need to learn the basics as mentioned below:

9. Form Helpers

The form helper file includes functions that help a developer to work with the forms. A few tools that you should use in react as a form helper are:

10API Clients

API clients provide an interface for different applications to communicate with each other when a request is made, these are:

REST

GraphQL

11Utility Libraries

Utility libraries are a collection of functions used to solve a common set of tasks and make the developer’s work easier. A few utility libraries that will be good to know about are:

12. Testing

Every programming language requires testing skills to analyze the errors or bugs in the lines of code before delivering it. Testing entails the following methods:

E2E Testing

  1. Selenium
  2. Cypress
  3. Cucumber.js
  4. Puppeteer
  5. Nightwatch.js

Integration Testing

  1. Karma

13Localizing App (i18n)

Localization or i18n is a simple translation module that has dynamic JSON storage. It is the process of designing and developing apps to be used in different locales around the globe. As a react developer, you will be using either of the two localization libraries:

14Server-Side Rendering

Server-side rendering or SSR is a technique for rendering a client-side single-page application on the server and then conveying a fully retrieved page to the client. A few frameworks for server-side rendering you must know are:

15Static Site Generator

A static site generator is a tool used for generating a fully static website on HTML through raw data and templates. One of the roles you can use as a static site generator is Gatsby, a tool for creating static websites with react.

16Integration of Backend Frameworks

Integrating backend frameworks with frontend so that they can work simultaneously is essential to learn about. For integration purposes, you can use React on Rails as suggested in the roadmap that makes it efficient to pass data to components.

17Mobile/Desktop/Virtual Reality App Development

Once you have learned the basics of React and its required tools, it is time to acknowledge some frameworks that will help you with app development for different platforms.

Bonus and Guidance

Step 1. Commit to 4-5 hours of coding per weekday

The most important factor in deciding how soon you will be able to learn React is time, and how you use it.

You must maintain a consistent coding routine throughout the week. It will be nearly impossible to meet your coding deadlines without this. The truth is that most individuals will never excel at React because they lack the time and effort required to code.

If you plan on coding every day from nine to five once you’re on the job, you need to have a similar schedule for yourself while learning. Ideally, you should spend around four to five hours of focused coding every weekday.

Step 2. Spend your time doing focused coding

What exactly do I mean when I say “targeted coding”? Coding without distraction is referred to as focused coding. In a separate quiet space, where you can sit upright at your computer, and focus entirely on the process of coding.

During this time, much of what you’re doing will not be 100% coding. As you code, you’ll be reading documentation, reading an article, taking notes, and so on.

If you’re focused on your work, four to five hours should be all that you need. The idea of coding 12 hours a day is not realistic, especially if you are getting started.

If you can spend more time and you do feel focused, go ahead. But it’s very hard to code and consume new information while you’re already tired.

Step 3. Use the Pomodoro technique for optimal time management

There is a special technique that will help you make the most out of that four to five hours. It’s called the Pomodoro technique. It’s an approach that’s made for optimal productivity and it consists of working in 25 minute periods at a time.

You start your timer and after each period, or pomodoro, you take a five minute break. During this break, get up from your chair. Have something to drink. Adjust your focus away from your computer or your phone. In short, take a real mental and physical break from what you’re doing.

Taking breaks with purpose and giving your brain and body a rest will help you make the most of your time. Instead of trying to work for hours on end. And after every fourth 25 minute period or pomodoro, you take a longer 15 minute break.

You will have a highly productive day if you accomplish 8-10 pomodoros of solid work. This is the best strategy for ensuring consistent outcomes day in and day out, and I use it every day I code. The only thing that will make the difference between learning React in months versus a year or more is consistent outcomes.

There are many free pomodoro timers that you can find online. I’ll link to a couple of them below:

Step 4. Read through ReactJS.org from front to back

We’ve talked about how to work and the amount of time to spend working, but how do you approach learning the skills needed to be a React developer?

Many developers would recommend diving right into whatever you can find. To look through various websites, articles, YouTube videos, and ebooks. In fact, there’s one best place to go to first to start working with and learning React. And that is reactjs.org.

How do you run the React code you find? Instead of trying to create a React application on your own computer, create a React app in the browser.

To create a new React app in two seconds, go to react.new. It will create a brand new React app in your browser that you can start working with.

Then start experimenting with examples from the React.js documentation. On your own, type in the code from the guides, run it, and see what works and what doesn’t.

Instead of reading a book and being told what code does, run the code yourself. See what happens when you try different things. To test the boundaries of React and what it can do is the best thing possible to understand how it works.

Step 5. Start small. Build small apps and learn to add features as you go

Once you have gone through the documentation at reactjs.org, start building small things. Try to build a todo application from scratch. If not a todo application, a basic CRUD application, a note-taking application, and so on. Make a complete app that consists of simple, clearly divisible parts.

Step 7. Actively coding is your key to success

This approach we’ve been talking about is very different than reading a book or article.

Reading or consuming information alone is called passive learning and is much slower. Actively coding yourself is active learning.

Step 8. Build apps similar to the ones you use daily (and know well)

After building your todo app, ask yourself can I make a small version of Twitter? Can I build a small version of Facebook or some other social network? Can I build a small version of Instagram?

Make something based on other apps you’ve used and are familiar with. As time goes on, you’ll notice that these applications all have similar features. It will take you from a mediocre to an exceptional, self-directed developer if you can spot common features in apps and implement them yourself.

Step 9. Deploy your best work and put it on your resume for employers

And finally, after building larger and larger applications, make sure to put all these projects on your resume. To do that, you’ll need to deploy them to the web first.

Deploying React apps is very simple. You need only learn how to use basic hosting services like Netlify or Heroku which are free and as simple as can be.

Include links to each project on your resume as well as a description of the app and the technologies you used to build it. Doing so will immediately show the value that you can bring to potential employers.

If you’re interested in becoming an independent app developer, try turning one of these projects into an actual business. You’d be surprised how many people are able to do that. They learn React, start building projects, and turn one of them into an app or service which they sell for a profit.
