Firebase cannot find databaseURL when separate databases are created with process.env

I wanted to have separate databases; one for testing and one for development and production. So using the process.env variables and a little library called node-env-file, I set the firebase config variables to the process.env variables. But I am getting this error:

> Uncaught Error: FIREBASE FATAL ERROR: Can't determine Firebase
> Database URL.  Be sure to include databaseURL option when calling
> firebase.intializeApp().

In the webpack.config file:

        var envFile = require('node-env-file');

        process.env.NODE_ENV = process.env.NODE_ENV || 'development';

        try {
          envFile(path.join(__dirname, 'config/' + process.env.NODE_ENV + '.env'));
        } catch (e) {

        } 

    // (...)

     plugins: [
        new webpack.DefinePlugin({
          'process.env': {
            NODE_ENV: JSON.stringify(process.env.NODE_ENV),
            API_KEY: JSON.stringify(process.env.API_KEY),
            AUTH_DOMAIN: JSON.stringify(process.env.AUTH_DOMAIN),
            DATABASE_URL: JSON.stringify(process.env.DATABASE_URL),
            STORAGE_BUCKET: JSON.stringify(process.env.STORAGE_BUCKET),
            MESSAGING_SENDER_ID: JSON.stringify(process.env.MESSAGING_SENDER_ID)

          }
        })
      ],

// (...)

In config/test.env

and in config/development.env

(these 2 files are similar, but of course the data is different):

API_KEY=myapikeyhere
AUTH_DOMAIN=myauthdomainhere
DATABASE_URL=mydatabaseurlhere
STORAGE_BUCKET=mystoragebuckethere
MESSAGING_SENDER_ID=memessagingsenderidhere

In firebase/index.js

:

import firebase from 'firebase';

try {
  var config = {
    apiKey: process.env.API_KEY,
    authDomain: process.env.AUTH_DOMAIN,
    databaseURL: process.env.DATABASE_URL,
    storageBucket: process.env.STORAGE_BUCKET,
    messagingSenderId: process.env.MESSAGING_SENDER_ID
  };

  firebase.initializeApp(config);
} catch (e) {

}

export var firebaseRef = firebase.database().ref();
export default firebase;

I have updated firebase and node-env file libraries.

In firebase / index.js file try

console.log("NODE_ENV",process.env.NODE_ENV) 
console.log("API_KEY",process.env.APP_KEY)

If API_KEY is undefined,



  • Make sure the config / folder is in the correct location.
  • Remove all spaces in .env files

If console.log shows API_KEY, it should work.

In webpack.config.js file replace .env file with the following

envFile(path.join(__dirname, 'config/' + process.env.NODE_ENV.trim() + '.env'));

So, you will get a truncated string.



I had the same problem and when I typed the error in the try / catch block I saw that envFile was trying to find a .env file like 'config / test. env. The spaces after the period were breaking the code. It came from a space here I think (between "test" and "& &") → "NODE_ENV = test && karma start".

A real hard case.
