Implement server that listens on process.env.PORT

In almost all the laboratory exercises of the JSNSD course it is required to implement a server that listens on the port present in process.env. To do this, just add the following code in app.js?
const {PORT} = process.env
module.exports = async function (fastify, opts) {
fastify.listen(PORT)
......
}
thanks

const port = process.env.PORT || 3000;
works fine.Your solution, too!
The mentionedconst {PORT} = process.env
works as well due to the JS destructing assignment (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment)Happy coding and good luck on your exam!

In a generated fastify project (
npm init fastify
) it uses fastify-cli.The fastify-cli tool will use the
PORT
env var automatically, you don't need to do anything in that case, it's doing that under the hood for you.0 -
@davidmarkclements, this is where that happens, correct? I've been trying to unwind the magic of
npm init fastify
