Using Environment Variables In ReactJS
So I've been setting up a new project and could not find any up-to-date explainations on how to do this, most people recommend to use
dotenv but apparently
dotenv is now included in
react-scripts, how can I make use of this? where would I declare environment variables and how would I tell it to use production/environment ones when running my project? I know it seems like a "go read the documentation" question but I couldn't find any, and it's a pretty straight-forward question. TIA.
You can add properties in
.env file in a key-value fashion
and reference them in your code with
You can inject these properties based on the environment you are having. So when you are in production, you simply overwrite these variables. Otherwise just read from
I personally don't use that file, but use in development a
node command which has all the variables. In production they are managed by Azure DevOps for example.
