# Deploy express on ts-node env to Heroku server

1. Set up Heroku environment

Heroku account is needed. Please sign one up for this application.

2. Install [heroku CLI](https://devcenter.heroku.com/articles/heroku-cli)

brew tap heroku/brew && brew install heroku

3. Log into Heroku account and create a new project

heroku login
heroku create <project name>

4. Make sure the heroku remote exists

git remote -v

5. Create Procfile

To make sure Heroku take use of ts-node, we will need to set up the following content in Procfile

    web:ts-node/src/index.ts

6. Make sure the following three npm packages are in "dependency" instead of "devDependency" because Heroku will use it as env commands.

    "ts-node": "^9.1.1",
    "typescript": "^4.0.2",
    "@types/node": "17.0.21"

7. Push code to heroku server to deploy

    git add .
    git commit -m"Init project"
    git push heroku master
