Laravel structure for a scalable monolith

Most apps I build are monoliths, and they hold up fine. The trick is not microservices, it is keeping one Laravel app organized: thin controllers, one class per job, slow work in queues, and an eye on the database.

How I use string enums in Laravel

A typo between 'complete' and 'completed' lived in production for two weeks. Since then every status is a string enum: cast on the model, validated with Rule::enum, with its labels, colors and rules inside it.

Rate limiting in Laravel: we built it ourselves, then Laravel shipped it

We needed limits per minute, per hour and per day, so we wrote a middleware with three cache counters. It had a race, wrong headers and a day that reset at 3:47 PM. Laravel's RateLimiter does all of it in three lines.

I wrote a rate limiter Laravel already had

A 190-line class with three windows, tests and hand-built headers, for an app on Laravel 8.83. Limit::perHour and perDay had been in vendor/ since 2020, and a named limiter can return all three at once.

Count only the responses you choose in a rate limit

Limit::after() decides after the response which requests count: only 404s for someone guessing ids, and never 422s, so a user fixing a form does not spend their own limit.

Lock the rebuild, not the read

Wrap the expensive rebuild in Cache::lock() so one request fills the key while the others wait a moment and read the result.

One details() match instead of label(), color() and hint()

Put everything the UI needs about a case in one array per case, and read label() and meta() from it; adding a case means one new arm, and match still throws when it is missing.

Give every enum the same ten lines

A small trait adds values(), names() and options() to every backed enum, so whereIn clauses, validation lists and select inputs read the cases instead of a copied array.
