I have an express API which I am hosting on Heroku. I created two projects: one project points at my Master Branch (Prod) and the other at my Development branch (Dev).
I have two scripts in my package JSON:
"scripts": {
"devStart": "export NODE_ENV=development && nodemon server.js",
"start": "export NODE_ENV=production && node server.js"
}
How can I make it so, that the development branch runs "DevStart" and Master runs "start". Currently Prod is working fine as node start is the default script.
I understand I can put commands in my procfile, however since both Dev and Prod use the same codebase, I would need to change this with each commit. Is there a dynamic way to do this?
Ok, This might not be the correct way but here is how I did it.
I seen you can set the NODE_ENV variable for the Heroku app using terminal:
heroku config:set NODE_ENV=development --app {app-name}
My package JSON though was overwriting this when the app deployed.
"scripts": {
"devStart": "export NODE_ENV=development && nodemon server.js",
"start": "export NODE_ENV=production && node server.js"
},
I changed it to:
"scripts": {
"localStart": "export NODE_ENV=development && nodemon server.js",
"start": "node server.js"
},
This now resolves the problem. No need for the Procfile or to setup environment variables within Heroku.
On Heroku I have two apps, one for production which I don't change the NODE_ENV variable as it defaults to production, and another for Development, which I do change the NODE_ENV variable to 'Development'.
Each app is hooked up to a different branch within the same code base ( Development(Development) & Master(Production) ). Any deploys to either branch will cause a rebuild using the correct NODE_ENV variable for each respective branch.
