Go Load Up Laravel Package

Getting Started

• composer require astrogoat/go-load-up and pin the constraint deliberately — a caret on a 0-star, thin-notes package means you absorb minors unreviewed.
• Look first at the package's own src/: the loader contract/interface, the registrar (the thing that collects loaders), and the service provider's register/boot. Those three files tell you more than the README, because the day-to-day API is "register a loader, run it in order" and everything else is sugar.
• Publish and read the config (php artisan vendor:publish), if one ships, before writing any loaders. The execution-order config is the whole point of the package; you want to see its shape before you build against it.
• Identify the smallest real bootstrapping task you already do in a service provider — registering a view composer, binding a singleton, setting a model observer, warming a settings cache. Move that one thing into a loader and confirm it still runs. Don't migrate your whole provider in the first pass.
• Verify the observable effect (cache populated, binding resolves, observer fires on a model save), not that the loader was "called." A loader that silently short-circuits due to order or condition is the failure mode you're checking for.

Implementation Patterns

• One loader per concern, named by intent. RegisterObserversLoader, WarmSettingsCacheLoader, BindReportGeneratorsLoader — not SetupLoader. When order matters (and it will), the name is what future-you reads in the config.
• Treat the execution order as configuration, not code. Register loaders and let the package's ordering mechanism decide sequence. If you find yourself reordering register() calls to force precedence, you've defeated the package's purpose — encode the dependency in the order config instead.
• Lean on conditional loading for environment splits. Local-only seeders, staging-only mail transport, production-only warmers — express these as loader conditions rather than if (app()->environment(...)) branches inside providers. That keeps prod boot paths and local boot paths visible in one place.
• Group with a provider per domain, register loaders inside it. A ReportingServiceProvider that registers three reporting loaders reads better than one god-provider registering thirty. The package is meant to clean up providers, not consolidate everything into a single mega-registration.
• Test loaders as units. A loader is (or should be) a small class with a load()-ish entry point; call it directly in a test, assert the side effect, and you never need to spin up the whole boot sequence to test one piece of setup. This is the main reason the pattern pays off in a small codebase.
• Call the runner explicitly from your own boot sequence if the package exposes it, rather than relying on magic auto-run. An explicit call in AppServiceProvider::boot() (or wherever) makes the ordering contract obvious to the next reader and easy to move when you need to slot loaders between existing steps.
• Wrap anything touching IO in a loader that can be skipped. Cache warmers, remote fetches, filesystem scans belong in loaders precisely because conditionals and ordering are first-class here. In a request cycle that's still a latency tax — combine with scheduling (see gotchas).

Gotchas and Tips

• Boot order is the bug you'll actually hit. Loaders that assume a binding, config value, or model table exists will fail with nulls or missing-relation errors — not at compile time, at request time, and only in the environment where the ordering differs. Test the full sequence in at least two environments (or with config cached) before shipping.
• config:cache changes everything. If your loader conditions or ordering read from config, run php artisan config:clear && php artisan config:cache and exercise the app again. Stale or freshly-cached config is the #1 cause of "the loader ran in local but not staging."
• Watch for double execution. If the package auto-runs loaders and you also call the runner from your provider, your warmers and observers register twice. Model observers in particular will fire twice and are painful to notice. Pick one invocation point and remove the other.
• Idempotency. Loaders that mutate state (registering observers, appending to a registry, pushing onto a collection) must tolerate being run more than once — this bites you in long-running workers (queue:work, Octane) or when a test boots the app repeatedly.
• Debug at the loader boundary. Log loader name + duration in a dev-only wrapper rather than dd()-ing inside vendor code. A Log::debug('loader:start', ...) pair around each loader shows you the real execution order in one request, which is the fastest way to diagnose ordering issues.
• Keep loaders cheap at boot. Anything a loader does runs on every request that boots the app. Move warmers into a scheduled command or a deploy step and have the loader trigger the job, not the work. The package makes the sequencing easy — don't mistake that for making the work free.
• Check the loader contract before extending. If loaders are classes implementing an interface, your own loaders should follow it exactly; if the package's registrar is macroable or event-dispatched, prefer binding/overriding over forking — upgrades on a low-signal package are safer when your integration surface is small.
• Pin the version and batch upgrades. With thin release notes, every bump is a diff read. composer.lock committed, upgrade on a branch, diff the lock, then merge — don't let ^ float you into a minor that quietly changes a default ordering or condition.
