## Evidence gaps

> Signals were refreshed at a different commit; written guidance still describes the analyzed commit.
> The repository license was not verified.
> Local setup commands, tests and compatibility with your checkout have not been verified by this context.
> Public and runtime candidates are based on file names; their exports and execution paths still need checking in source.
> The file list was refreshed after the written analysis. Subsystem descriptions and suggested changes may describe an older revision.
> Could not capture pnpm-lock.yaml: source unavailable or larger than the capture limit. Open its source link to check setup.
> The intended package manager and version are not established by captured evidence.
> Runtime versions and other prerequisites were not captured.
> Root development commands were not established. Check the root manifest and contributor guide.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.

1

Add integration tests for config parsing and validation layers

The config package has many specialized modules (auth/, config-diff.ts, config-edit.ts, functions-manifest.ts) with corresponding unit tests, but the repository structure suggests missing integration tests that validate how these config layers interact together. The packages/api/src shows lifecycle integration tests (bun-lifecycle.integration.test.ts, node-lifecycle.integration.test.ts), indicating this pattern is established. Adding similar integration tests for config layer composition would catch bugs in real-world config workflows.

Checklist

  • ◦Create packages/config/src/config-integration.test.ts
  • ◦Test loading and merging multiple config sections (auth + functions + db)
  • ◦Test config-diff.ts against realistic config transitions
  • ◦Test config-edit.ts modifications persist correctly across layer composition
  • ◦Verify auth/ submodule validation integrates with parent config validation
2

Add comprehensive unit tests for packages/config/src/lib/resolve.ts

The file packages/config/src/lib/resolve.ts exists and is likely critical for environment variable and config resolution, but there is a corresponding resolve.unit.test.ts. However, given the presence of env.unit.test.ts and schema.ts, the resolve module likely handles complex path/reference resolution logic. This is a high-risk area for edge cases (circular references, missing env vars, type coercion) that needs extensive coverage for a CLI tool managing infrastructure.

Checklist

  • ◦Audit packages/config/src/lib/resolve.ts for branching logic and edge cases
  • ◦Add tests for circular dependency detection in config references
  • ◦Add tests for missing environment variable fallback behavior
  • ◦Add tests for type coercion and validation during resolution
  • ◦Add tests for resolution with nested/inherited config structures
3

Add client integration tests for packages/api/src/internal/ client implementations

The packages/api/src/internal/ directory contains three client implementations (client.ts, effect-client.ts, promise-client.ts) with unit tests for client.ts and promise-client.ts, but effect-client.ts lacks a corresponding test file. For an API package that must support multiple runtime models (Effect, Promise, direct), ensuring all three implementations handle the same contract correctly is critical. The generated/effect-client.ts and generated-contract-sync.unit.test.ts suggest this is actively used.

Checklist

  • ◦Create packages/api/src/internal/effect-client.unit.test.ts
  • ◦Mirror test cases from promise-client.unit.test.ts to ensure parity
  • ◦Test Effect error handling and recovery paths
  • ◦Test integration with generated/effect-client.ts contract
  • ◦Verify effect-client.ts handles async lifecycle events correctly

Concepts to learn

7

Non-obvious concepts named or implemented in this codebase. Click any link to read the canonical explanation.

Effect-based functional programming (async/error composition)

The codebase uses the Effect library (packages/api/src/effect.ts) as its primary abstraction for managing side effects, errors, and async operations; understanding Effect.gen(), Effect.all(), and dependency injection is essential for reading or modifying API layer code

effect.website

Schema-as-code / Configuration as structured types

packages/config/src/ defines database, auth, functions, and compute configurations as TypeScript schemas (not YAML/JSON files); this enables type-safe config diffing, validation, and code generation

zod.dev

OpenAPI contract generation and synchronization

The CLI generates TypeScript contracts from an OpenAPI schema (generated/openapi.json → generated/contracts.ts); understanding how schema changes trigger contract regeneration prevents manual sync errors (see generated-contract-sync.unit.test.ts)

www.openapis.org

Monorepo with Turbo task orchestration

The project uses pnpm workspaces + Turbo to coordinate builds, tests, and type generation across packages (api, config, cli-test-helpers, e2e); CI/CD and local dev depend on correct task dependency graphs

turbo.build

Database migration diffing (schema introspection and comparison)

packages/config/src/config-diff.ts and db.ts handle detecting changes between local Postgres state and remote/desired state; this is the engine behind `supabase db diff` and `supabase db push`

www.postgresql.org

Edge function manifest and deployment bundling

packages/config/src/functions-manifest.ts parses and validates edge function definitions (deno/ts edge functions); understanding manifest structure is needed for the `supabase functions new` and deploy workflows

deno.land

Local Docker Compose orchestration (multi-service coordination)

The CLI starts Postgres, Auth, Realtime, Storage, and Edge Functions via Docker Compose; this is implicit in the CLI's architecture; understanding container lifecycle and networking is needed for debugging local stack issues
