Heroku Cheatsheet

m2-heroku-cheatsheet.md

Heroku commands

• Authenticate

  • heroku login

• Open the app in the browser (from terminal)

  • heroku open

• See logs

  • heroku logs
  • heroku logs -n 200
  • heroku logs --tail (display logs real-time)

• Open a command line terminal in our Heroku server

  • heroku run bash
  • Note: this can be helpful, for example, if we want to run our seed file (once you're there, you can execute the seed file on the heroku server, ex: node bin/seed.js)

Deploy

• Option 1: manual deploy

  • Setup: we need to install heroku CLI + configure heroku as a remote repository (details here)
  • To deploy on production (push our code to the remote repository on heroku): git push heroku main

• Option 2: automatic deploys from GitHub

  • Setup: configure automatic deploys (details here)
  • To deploy on production: push your code to github (ex. git push origin main)

Extra: Setup to work in pairs (so that all members can push to Heroku)

Student 1 = the one that deployed the project on heroku
Student 2 = any other student/s in a team

Steps:

• Student 1: share with your team mate the name of the heroku app
• Student 2: shares with your team mate the email address that you used to create the account on heroku (if you don't remember which email address you used, check screenshot)
• Student 1: heroku > Access > Add collaborator > Add email address of collaborator/s
• Student 2:
  • in the command line, go to the root directory of m2-project
  • heroku login (browser will open)
  • add remote repository: heroku git:remote -a nameOfOurProject
  • now you should be able to push to heroku, see logs, etc
