Task-focused recipes for every Base subsystem. Find the job, follow the steps.

How Base Works

What decorators record, when your application is assembled, and what runs on each event.

Routes, parameters, validation, headers, middleware, and CORS.

Entities, relations, migrations, queries, and writes on Drizzle-backed databases.

The default way to call a Base worker, typed end to end, from the web and between workers.

Injectable services, lifetimes and scopes, typed keys, and providers.

The per-request view of everything, for reading request state, writing response state, and deferring work.

Typed object and input classes, resolvers, and the schema workflow.

One validation pipeline for HTTP, GraphQL, and RPC, covering rules, errors, and custom decorators.

Typed wire shapes: serializable classes, field options, and transformers.

Unit tests with plain jest, integration tests against a live worker, and module test suites.

Package features as reusable modules: settings, dependencies, registration modifiers, and composition.

KV, R2 object storage, Durable Objects, and containers.

Produce and process Cloudflare Queue messages with typed envelopes.

Cron-driven executables, local testing, and Durable Object alarms.

The in-process event bus, with decoupled listeners and immediate or deferred emission.

Socket delegates, authorized upgrades, and Durable Object-backed connections.

Session-based access control and encrypted tokens.

The base command line, from fundamentals to the development loop and the full command reference.

Environments, configuration layering, deploy gates, continuous deployment, and platform targets.

Breakpoints against the local runtime, live logs from production.

Level-gated logging with thresholds, categories, and the request log.
