ievj
Interpolation or replacement of environment variables in a JSON.
Why
Because this is just what I needed and I could not find a library that did just this - as opposed using a library that does 1192820282 other things and brings other transitive dependencies.
I decided to publish it in case someone else finds it useful.
How
npm add @agseco/ievj
or
yarn add @agseco/ievj
And then something like this:
const interpolateEnvVars = require('@agseco/ievj');
const myObject = {
path: '${env.BASE_PATH}/shared/path'
};
process.env.BASE_PATH = '/dev/path';
const interpolated = interpolateEnvVars(myObject);
console.log(interpolated);
Result:
{ path: '/dev/path/shared/path' }
See unit tests for more examples.
How I use it
In case this is what you are looking for. I'm combining it with:
-
dotenv - to automatically populate
process.env - node-config - to replace some environment variables in my configuration files
