I have worked on Laravel projects that started clean and slowly turned into a mess. It is not always the developer's fault. Sometimes you are moving fast, deadlines are tight, and you just want things to work. But a few small habits — if you build them early — save you enormous pain later.
Here is what I actually use on real projects.
Keep your controllers thin
This is the one I see broken most often. Controllers should do one thing: take a request, call something, return a response. That is it. When I see a controller method that is 80 lines long with database queries, email sending, and file uploads all mixed together — that is a sign the project will be hard to maintain.
Move your business logic into service classes. A UserRegistrationService or OrderProcessor class is much easier to test and reuse than a fat controller.
Validate with Form Requests, not inline
You can validate inside a controller method. It works. But when you have 10 fields and complex rules, your controller becomes unreadable. Form Request classes keep validation in one place and your controller stays clean.
Another benefit — you can reuse the same Form Request in multiple places.
The N+1 problem will kill your app
This one is sneaky. You load a list of posts, then in your Blade template you access $post->author->name for each one. Looks fine. But Laravel is running a separate database query for every single post. If you have 100 posts, that is 101 queries.
Fix it with eager loading:
$posts = Post::with('author', 'tags')->paginate(20);Install Laravel Debugbar in development. It shows you exactly how many queries each page is running. You will be surprised.
Push slow things to queues
Sending an email, resizing an image, calling an external API — none of these should happen inside a web request. The user is waiting. Push them to a queue and let a background worker handle it.
Laravel's queue system is excellent. Once you start using it, you will wonder how you lived without it.
Cache aggressively, but carefully
Database queries that run on every page load and return the same data are a waste. Cache them. But be careful — stale cache is worse than slow cache. Always think about when to invalidate.
Redis is the right choice for production caching. The file driver is fine for development.
Never hardcode secrets
I still see API keys in source code. Please do not do this. Use .env files. Use config() helpers to access them. Never commit .env to version control.
Write at least some tests
I know, I know. Tests take time. But a feature test that covers your main user flows will save you hours of manual testing every time you make a change. Start small. Test the things that would hurt most if they broke.
Use migrations for everything
Every database change should be a migration. No exceptions. If you make a manual change to a production database and forget to write a migration, the next developer who sets up the project will have a different database than production. That causes bugs that are very hard to track down.
Run the production optimizations
Before you deploy, run these:
php artisan config:cache
php artisan route:cache
php artisan view:cache
composer install --optimize-autoloader --no-devThese commands make your app noticeably faster. They take 10 seconds to run and should be part of every deployment.
Use Telescope in development
Laravel Telescope shows you every request, query, job, and exception in a clean UI. It is the fastest way to spot problems before they reach production. Install it in your development environment and leave it running.
These are not revolutionary ideas. They are just habits. Build them early and your projects will be much easier to work with as they grow.
