Problem: wanted to pass environment variables to an app created with create-react-app ( in development )
This is how I did it ( not exactly sure which version of react-scripts I’m using, since I ejected the config ):
- create a .env.development file, in your app’s root folder and add your variables there:
API_URL=http://api.local- open config/envs.js and add your variable to the object in getClientEnvironment function:
{
// Useful for determining whether we’re running in production mode.
// Most importantly, it switches React into the correct mode.
NODE_ENV: process.env.NODE_ENV || 'development',
// Useful for resolving the correct path to static assets in `public`.
// For example, <img src={process.env.PUBLIC_URL + '/img/logo.png'} />.
// This should only be used as an escape hatch. Normally you would put
// images into the `src` and `import` them in code to get their paths.
PUBLIC_URL: publicUrl,
API_URL: process.env.API_URL,
}
