How to upgrade a React project built with create-react-app to the next create-react-app version?

Question

I have a React project built with create-react-app 1.5. I would like to get the features of create-react-app 2.0 for my React project.

Specifically I would like to use this: https://github.com/facebook/create-react-app/pull/3909

Answer 1

Basically, to upgrade a create-react-app project, all you need to do is update the react-scripts module to the latest version and update your app to be compatible with any breaking changes in react-scripts .

Run yarn upgrade --latest react-scripts , rebuild your app, and everything should more-or-less work, barring any breaking changes.

Create React App is divided into two packages:

create-react-app is a global command-line utility that you use to create new projects. react-scripts is a development dependency in the generated projects (including this one). When you run npx create-react-app my-app it automatically installs the latest version of Create React App.

If you've previously installed create-react-app globally via npm install -g create-react-app , please visit Getting Started to learn about current installation steps.
