How to specify environment variables in loopback 4?

Question

I found documentation for the previous version https://loopback.io/doc/en/lb3/Environment-specific-configuration.html but I can't find a documentation for the version 4

There's something I'm missing or v4 doesn't yet support environment specific configuration?

Even I couldn't find how to specify configuration in loopback 4. I was trying to configure a common base path for all the APIs. – Archoplasm

hey dude, I put my dotenv configuration in index.js (next to the package.json) and it worked !!! If you want similar solution try... – Torrie

After breaking my head looking for documentation - these are the steps I used to handle environment configuration:

1. Step 1: Install dotenv package

   npm install --s dotenv

2. Add a .env file to the root of your project (server/.env). Sample format in this file given below:

   SampleKey=testValue

3. Require this file from the index.js file (I placed this on line 2)

   // Addition of dotenv for access to process.env (environment variables) const dotenv = require('dotenv').config();

4. You should be able to access keys from your file now as follows:

   console.log(process.env.SampleKey);

Loopback 4 doesn't support environment specific configurations yet. Check this post https://mcmap.net/q/1015981/-loopback-4-test-configurations-are-not-picked-up

You can follow this github issue for the same. https://github.com/strongloop/loopback-next/issues/1464
