To set environment variables from within package.json, we can put the keys and values of the environment variables before the command we run.
For instance, we write
...
"scripts": {
"start": "node app.js",
"test": "NODE_ENV=test mocha --reporter spec"
},
...
to add the test script that sets the NODE_ENV environment variable to test.
And then we run the mocha command with the environment variable set.
