5 Mistakes I Made When Starting My First React Project

You know what it’s like to pick up a new language or framework. Sometimes there’s great documentation to help you find your way through it. But even the best documentation doesn’t cover absolutely everything. And when you work with something that’s new, you’re bound to find a problem that doesn’t have a written solution.

That’s how it was for me the first time I created a React project — and React is one of those frameworks with remarkable documentation, especially now with the beta docs. But I still struggled my way through. It’s been quite a while since that project, but the lessons I gained from it are still fresh in my mind. And even though there are a lot of React “how-to” tutorials in out there, I thought I’d share what I wish I knew when I first used it.

So, that’s what this article is — a list of the early mistakes I made. I hope they help make learning React a lot smoother for you.

Using create-react-app to start a project

TL;DR Use Vite or Parcel.

Create React App (CRA) is a tool that helps you set up a new React project. It creates a development environment with the best configuration options for most React projects. This means you don’t have to spend time configuring anything yourself.

As a beginner, this seemed like a great way to start my work! No configuration! Just start coding!

CRA uses two popular packages to achieve this, webpack and Babel. webpack is a web bundler that optimizes all of the assets in your project, such as JavaScript, CSS, and images. Babel is a tool that allows you to use newer JavaScript features, even if some browsers don’t support them.

Both are good, but there are newer tools that can do the job better, specifically Vite and Speedy Web Compiler (SWC).

These new and improved alternatives are faster and easier to configure than webpack and Babel. This makes it easier to adjust the configuration which is difficult to do in create-react-app without ejecting.

To use them both when setting up a new React project you have to make sure you have Node version 12 or higher installed, then run the following command.

npm create vite

You’ll be asked to pick a name for your project. Once you do that, select React from the list of frameworks. After that, you can select either Javascript + SWC or Typescript + SWC

Then you’ll have to change directory cd into your project and run the following command;

npm i && npm run dev

This should run a development server for your site with the URL localhost:5173
