Hello everyone,
For a school assignment, I need to deploy a Laravel project on Heroku with a login system. I'm using a Laravel Breeze package for this. Now I'm having a problem with installing this package on Heroku. I used the "heroku run composer require laravel/breeze --dev" but it doesn't seem to work.
Is there someone in this forum with some knowledge about Heroku and Laravel? (Maybe this is the wrong forum)
Kind regards, Jan
@freazling You shouldn’t be running Composer commands on your Heroku app. The app is served by “dynos” which means it doesn’t have a persistent disk. Any changes you make to an app in a dyno won’t be saved.
You should be running Composer commands in your local Laravel project, committing the changes with Git, and then pushing the app to Heroku.
Thank you for your reply. I will look into this!
Also from their help:
But the technique @martinbean stated is the best for Heroku.
For some host I ssh in with putty, but that's not for Heroku.
Thank you for your reply. I will look into this aswell!
Install it locally and once you deploy it from your repo to your heroku app, you'll then need to save the config variables. However you must log in to bash and run php artisan migrate, for this you must be signed in to your Heroku account from the Terminal or CMD line via heroku login. After youu've migrated the tables it should work. But mind the config variables first, use the same ones you see on your .env now, in order to run a database system you'll need PGSQL which is a free add-on that comes with heroku.
This is somehow how the flow of it goes. Hope it helps.
Thank you for the reply. I have already set up my heroku (Might had to say that earlier). The problem is that the log in form doesn't have any CSS and it doesn't work (I have a screenshot, but I can't upload it yet)

@freazling Then you either need to build your assets locally with Mix and include it in your repository before pushing, or add the Node.js build pack and build your assets on push.
The former is easier, but the drawback is every time you change your styles you need to remember to commit the generated stylesheets.
Well, i know that's an 8 months old question but wth A step by step guide here. https://dev.to/moose_said/deploy-laravel-projects-with-database-for-free-5778
