# CLAUDE.md
|
|
|
|
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
|
|
|
## Project Overview
|
|
|
|
Core API is the REST framework for the Lethean ecosystem, providing both a **Go HTTP engine** (Gin-based, with OpenAPI generation, WebSocket/SSE, ToolBridge) and a **PHP Laravel package** (rate limiting, webhooks, API key management, OpenAPI documentation). Both halves serve the same purpose in their respective stacks.
|
|
|
|
Module: `forge.lthn.ai/core/api` | Package: `lthn/api` | Licence: EUPL-1.2
|
|
|
|
## Build and Test Commands
|
|
|
|
### Go
|
|
|
|
```bash
|
|
core build # Build binary (if cmd/ has main)
|
|
go build ./... # Build library
|
|
|
|
core go test # Run all Go tests
|
|
core go test --run TestName # Run a single test
|
|
core go cov # Coverage report
|
|
core go cov --open # Open HTML coverage in browser
|
|
core go qa # Format + vet + lint + test
|
|
core go qa full # Also race detector, vuln scan, security audit
|
|
core go fmt # gofmt
|
|
core go lint # golangci-lint
|
|
core go vet # go vet
|
|
```
|
|
|
|
### PHP (from repo root)
|
|
|
|
```bash
|
|
composer test # Run all PHP tests (Pest)
|
|
composer test -- --filter=ApiKey # Single test
|
|
composer lint # Laravel Pint (PSR-12)
|
|
./vendor/bin/pint --dirty # Format changed files
|
|
```
|
|
|
|
Tests live in `src/php/src/Api/Tests/Feature/` (in-source) and `src/php/tests/` (standalone).
|
|
|
|
## Architecture
|
|
|
|
### Go Engine (root-level .go files)
|
|
|
|
`Engine` is the central type, configured via functional `Option` functions passed to `New()`:
|
|
|
|
```go
|
|
engine, _ := api.New(api.WithAddr(":8080"), api.WithCORS("*"), api.WithSwagger(...))
|
|
engine.Register(myRouteGroup)
|
|
engine.Serve(ctx)
|
|
```
|
|
|
|
**Extension interfaces** (`group.go`):
|
|
- `RouteGroup` — minimum: `Name()`, `BasePath()`, `RegisterRoutes(*gin.RouterGroup)`
|
|
- `StreamGroup` — optional: `Channels() []string` for WebSocket
|
|
- `DescribableGroup` — extends RouteGroup with `Describe() []RouteDescription` for OpenAPI
|
|
|
|
**ToolBridge** (`bridge.go`): Converts `ToolDescriptor` structs into `POST /{tool_name}` REST endpoints with auto-generated OpenAPI paths.
|
|
|
|
**Authentication** (`authentik.go`): Authentik OIDC integration + static bearer token. Permissive middleware with `RequireAuth()` / `RequireGroup()` guards.
|
|
|
|
**OpenAPI** (`openapi.go`, `export.go`, `codegen.go`): `SpecBuilder.Build()` generates OpenAPI 3.1 JSON. `SDKGenerator` wraps openapi-generator-cli for 11 languages.
|
|
|
|
**CLI** (`cmd/api/`): Registers `core api spec` and `core api sdk` commands.
|
|
|
|
### PHP Package (`src/php/`)
|
|
|
|
Three namespace roots:
|
|
|
|
| Namespace | Path | Role |
|
|
|-----------|------|------|
|
|
| `Core\Front\Api` | `src/php/src/Front/Api/` | API frontage — middleware, versioning, auto-discovered provider |
|
|
| `Core\Api` | `src/php/src/Api/` | Backend — auth, scopes, models, webhooks, OpenAPI docs |
|
|
| `Core\Website\Api` | `src/php/src/Website/Api/` | Documentation UI — controllers, Blade views, web routes |
|
|
|
|
Boot chain: `Front\Api\Boot` (auto-discovered) fires `ApiRoutesRegistering` -> `Api\Boot` registers middleware and routes.
|
|
|
|
Key services: `WebhookService`, `RateLimitService`, `IpRestrictionService`, `OpenApiBuilder`, `ApiKeyService`.
|
|
|
|
## Conventions
|
|
|
|
- **UK English** in all user-facing strings and docs (colour, organisation, unauthorised)
|
|
- **SPDX headers** in Go files: `// SPDX-License-Identifier: EUPL-1.2`
|
|
- **`declare(strict_types=1);`** in every PHP file
|
|
- **Full type hints** on all PHP parameters and return types
|
|
- **Pest syntax** for PHP tests (not PHPUnit)
|
|
- **Flux Pro** components in Livewire views; **Font Awesome** icons
|
|
- **Conventional commits**: `type(scope): description`
|
|
- **Co-Author**: `Co-Authored-By: Virgil <virgil@lethean.io>`
|
|
- Go test names use `_Good` / `_Bad` / `_Ugly` suffixes
|
|
|
