Setting environment variables in Meteor yields errors in console

Trying to set something as simple as the MAIL_URL variable yields the following error in my terminal after running meteor.

server/main.ts (14,5): Cannot find name 'process'.

With line 14 being: process.env.MAIL_URL = 'smtp://account:password@smtp.server.com:465'

This is held inside my Meteor.startup(() => { }); method.

Am I missing an import? What am I doing wrong?

Solution

Cannot find name 'process'

process is a global available in nodejs : https://nodejs.org/api/process.html

To use this global add the type definitions for nodejs npm install @types/node --save-dev.
