App blank when deploying to heroku

[vlance11]

The app is beautiful, and it runs flawlessly on local. When deploying to Heroku it just returns a blank page. DB was seeded successfully. Error in the console is "Uncaught SyntaxError: Unexpected token <"

@vlance11 I haven't deployed this app to Heroku, I will try myself and get back to you soon.

@tuandm Thank you, as a heads up the 2 mysql db options do not work on heroku, must use postgres.

As ClearDB mysql is version 5.5 which has the 787 error and the JawsDB fails to connect for seed. Should the app be built as PHP or Nodejs?

[tuandm]

@vlance11 The app is actually a Laravel instance with VueJS as frontend. The app should work without NodeJS, just run npm run production from local then copy public/js/*, public/css/* files to Heroku.

I believe the problems you've got are related to Laravel.
Mysql 5.5 would get 767, I'm not sure about the 787 one, maybe typo? :)

Have you tried to install fresh Laravel on your Hekuro instance? (with proper mysql connection)

@tuandm -- I was able to solve by adding "heroku-postbuild": "npm run build" to the package.json file

Now the page displays correctly, but when logging in we see
Request failed with status code 404 -- the console has https://site/api/auth/login as a 404

We have added MIX_BASE_API and BASE_API to the hosted environment variables as well

[tuandm]

@vlance11 Thanks for updating. MIX_BASE_API/BASE_API are for frontend calling to /api/auth/login correctly, and they worked as https://site/api/auth/login is called.

404 means the route doesn't exist. And npm run build is not in package.json - you should try npm run dev or npm run production.

Already resolved thanks for the order
here is the working app on Heroku
https://laravel-coder.herokuapp.com

Solution :
when you push to heroku it will not push node_modules and public/js folder
please remove node_modules and public folder from .gitignore and then push again and it will work like a charm

Cheers
