Why you should use create-react-app to Scaffold your Next React App?
Update: This article is written in 2018 where
create-react-appdidn’t have many alternatives. In 2021 and beyond, I recommend and use vite, for scaffolding React application, it offers almost all functionalities of
create-react-appwith faster startup time.
In this article, I am going to share why we should stop building custom webpack config and instead use create-react-app to scaffold our react application.
React is great. Out of the box, it is just a view library. The ecosystem around React is really great and it’s huge.
We have to basically pick the react compatible parts like router, state management library for building our application. This is a really tiring task.
Setting up a modern react app from scratch is not easy and it makes us lost in the process due to a lot of overwhelming choices.
React is evolving really fast. And so the tooling around it.
If you are trying to set up everything from scratch, you need to hassle with lot more things like
babel which is a different world altogether.
create-react-apphelps in avoiding those hassles and enables us to focus on the application rather than the configuration.
create-react-app was available to developers since 2016, I have seen many people still searching for boilerplate and trying to set up the project from scratch even in 2018. This motivated me to write about this topic.
Over the period of 2 years, the create-react-app has matured a lot and provides a lot of cool features out of the box and drop in support for some features.
Scaffolding a React project with
create-react-app is super easy. No global installations of CLIs needed. If you use the recent versions on
npm, then run
npm init react-app
If you are on the
yarn team, then run
yarn create react-app
This will create a folder, with the project structure that is specified in documentation. It has some built-in scripts to develop with ease using features like auto reload, linting, error messages and building minified production ready bundle.
Before looking into the pros and cons of using
create-react-app, let’s see some of the features that are provided along with it, which can work without any configuration. I will give a small subset of features and the links for the docs.
Lot of the developers use SASS. There is a drop in support for SASS as well. Just install
node-sassto your project and you are good to go. All the files with
.sassextension will be taken by the SASS preprocessor. Learn more about it on the docs.
The CSS files in the bundle will be minified and vendor prefixed using autoprefixer. Based on your target audience, you can enable polyfills for new CSS features using
package.json. Learn more about it on the docs.
Support for custom environment variables using
.envfiles. Learn more about it on the docs.
Opt-in support for PWAs. You will get
manifest.jsonand Service Worker files out of the box. You just need to customize
manifest.jsonaccording to your needs and enable service worker. Learn more about it on the docs.
As you see,
create-react-app provides a lot of great features to build. In addition to that, there are a lot of advantages and some disadvantages of using
create-react-app to scaffold your application.
You don’t need to break yourself in configuration. You can just focus yourself on building the app.
Saves a lot of time and energy as it provides a lot of common things out of the box.
Training a newcomer about your project is easy. You just need to train them about the project and point them to the
create-react-appdocumentation for setup and configuration.
As it is maintained by Facebook, support for new features of React will be available immediately.
Updating to a new version is super easy. Just replace the version of
npm install. That’s it.
Speaking of updating, as
create-react-apptakes care of handling under the hood things, updating things like
babelwill be taken care by them. We don’t need to hassle with it again.
It provides an opinionated option for building a react app. Not everyone will like that.
It helps only if you are starting a project from scratch. It won’t help on the case of your existing application where you need to partially migrate to react.
The choices provided by create-react-app is not enough? You can easily opt-out by running
npm run eject
This will copy all the configuration files like
eslint into your project and gives you choice to customize it.
As you see, using
create-react-app provides you with a lot of advantages over building custom webpack config.
Hope I have given an overview of the features of
create-react-app and convinced you to choose it for your next React project.
Starting a new React project? Which path are you gonna choose?
create-react-app or custom config from scratch?
Are you using
create-react-app on your existing app? Are you facing any issue with it?
