FAQ

Should I commit my .env file?

No. The .env file should not be version controlled. Your .env will differ depending on deployment point, e.g. development will have different API endpoints compared to production. However, you can commit an example file which allows easy modification for e.g. CI builds.

Should I have multiple .env files?

No. Your .env should vary between deploys and you should not be sharing values between environments.
