There is no possibility to run build for specyfic env

I have to build my app for enviroment diffrent then production. After looking into react-app-rewired/scripts/build.js i see that there is no such option.

You have misunderstood what the node env (NODE_ENV) is used for. The NODE_ENV variable defines the type of build to be done, NOT where the build is to be deployed. (i.e. How, not Where).

There are 3 valid env's:

• 'test': a node test environment for running tests.
• 'development': an environment which has not had code stripped, and runs interactively in the Webpack Dev Server to enable easy debugging/reload on save/etc.
• 'production': a fully pre-built website with code minification, stripping out unused code, etc, for deployment as a website on a server somewhere.

If env wasn't supplied, it's assumed to be 'development'.

There can be multiple 'production' environments for where the site is deployed/hosted. You do not change the node env value for them - you build them with separate environment settings in the .env file.

i.e. if you have a 'staging' and a 'production' deployment, you'd build both sites with 'env' set to production (so that you get the fully pre-built website), but would have different environment variables in your .env files when building the two sites. You can have a separate custom .env file for different sites - e.g. .env.staging, .env.qa, etc.

See CRA's documentation on environment variables and on building for multiple environments with custom .env files.

Yep. I attempt to build staging env without env-cmd installed. I assumed that react-app-rewired can do it by itself. My bead.
