@g1suite/api-cli

CLI for scaffolding API Node servers and Cloudflare Worker apps, plus generating routes with paths and per-method handlers.

Quickstart

• Create an API project:

nx run api-cli:build
node dist/cli.js create --name my-api --template api --dir apps/my-api

• Create a Cloudflare Worker project:

node dist/cli.js create --name my-worker --template cloudflare-worker --dir apps/my-worker

Generate Routes

• API route with dynamic params and methods:

node dist/cli.js generate route --name user --path "/users/:id" --methods "GET,DELETE" --dir apps/my-api
# Produces: apps/my-api/src/routes/v1/users/[id].ts (version auto-detected)
# Exports named methods: GET, DELETE

• Override target API version and use dry-run:

# Explicitly write under v2
node dist/cli.js generate route --name hello --dir apps/my-api --api-version v2
# Preview planned files without writing
node dist/cli.js generate route --name hello --dir apps/my-api --dry-run

• Scaffold a new API version module:

node dist/cli.js generate version --api-version v2 --dir apps/my-api
# Produces: apps/my-api/src/routes/v2/index.ts

• Create an aggregated routes index and optionally patch app.ts:

node dist/cli.js generate aggregated --dir apps/my-api --patch-app
# Writes: apps/my-api/src/routes/index.ts that imports all detected versions
# If --patch-app is set, adds import and calls registerAllVersions(app) in src/app.ts

• Worker route with dynamic params and method map:

node dist/cli.js generate route --name user --path "/users/:id" --methods "GET,DELETE" --dir apps/my-worker
# Registers in src/routes/index.ts as a method map for "/users/:id"

Path Conventions

• API routes are versioned under src/routes/<version>/... (e.g., src/routes/v1).
• Detection order for target version:
  • .g1api.json defaultApiVersion (if present)
  • src/app.ts import/mount patterns (e.g., from './routes/<ver>/index' or app.route('/<ver>', vApp))
  • Filesystem: existing src/routes/<ver>/index.ts
  • Fallback: v1
• You can override detection using --api-version <ver> on generate route.
• Aggregated index lives at src/routes/index.ts and mounts each version under its prefix.
• API filenames use bracket params: src/routes/v1/users/[id].ts maps to /users/:id at runtime.
• Worker paths accept either /users/:id or /users/[id] in the registry; both are supported by the template router.

Method Handling

• API: Named exports (e.g., export async function GET) are registered per method by the framework loader. If only a default export exists, it is treated as GET.
• Worker: A single function is treated as GET-only. Method maps dispatch strictly per-method and return 405 for unsupported methods.

Start Commands

• API dev server:

node dist/cli.js start --dir apps/my-api
# Runs: bunx tsx scripts/prepare-docs-assets.ts && bunx tsx watch src/server.ts

• Worker dev server:

node dist/cli.js start --dir apps/my-worker
# Prints: wrangler dev

Nx Start Target

• Run via Nx (dry-run to preview):

nx run api-cli:start -- --dry-run --dir templates/project/api
# Outputs: Start command: bunx tsx watch src/server.ts

• Start an API project:

nx run api-cli:start -- --dir apps/my-api

• Start a Worker project:

nx run api-cli:start -- --dir apps/my-worker

• Notes:
• --dir is resolved relative to packages/api-cli when run via Nx.
• Use paths like templates/project/api or absolute paths for fixtures.
• The CLI auto-detects template type by presence of src/server.ts (API) or wrangler.toml (Worker).

Dev Alias and Workspace Root

• Use the dev alias:

nx run api-cli:dev -- --dry-run --dir templates/project/cloudflare-worker

• Resolve --dir from workspace root:

nx run api-cli:start -- --dry-run --root --dir packages/api-cli/templates/project/api
nx run api-cli:dev   -- --dry-run --root --dir packages/api-cli/templates/project/cloudflare-worker

Install & Usage

• Use the latest published CLI without local build:

npx @g1suite/api-cli@latest create --name my-api --template api --dir apps/my-api
npx @g1suite/api-cli@latest update --dir apps/my-api
npx @g1suite/api-cli@latest doctor --dir apps/my-api
npx @g1suite/api-cli@latest migrate --dir apps/my-api --dry-run

• Or via bunx if installed:

bunx @g1suite/api-cli create --name my-worker --template cloudflare-worker --dir apps/my-worker

Notes:

• --root resolves --dir relative to the Nx workspace root.
• Without --root, --dir resolves relative to the current working directory.

Template Metadata

• Projects created with create include a g1-template.json file at the project root:

{
  "template": "api",
  "templateVersion": "2.0.0",
  "files": {
    "src/server.ts": "<sha256>",
    "src/routes/index.ts": "<sha256>"
  }
}

• This metadata helps the CLI detect divergence and plan upgrades.

Update & Doctor

• Analyze project divergence and dependency versions without changing files:

node dist/cli.js update --dir apps/my-api
# or
npx @g1suite/api-cli@latest update --dir apps/my-api

• Print a quick health report (CLI version, template version, file status):

node dist/cli.js doctor --dir apps/my-api
# or
npx @g1suite/api-cli@latest doctor --dir apps/my-api

Migrate (Stub)

• Show a conceptual migration plan between template versions (no changes applied):

node dist/cli.js migrate --dir apps/my-api --dry-run
# or
npx @g1suite/api-cli@latest migrate --dir apps/my-api --dry-run

• Planned steps include:
• Update runtime dependencies (bun update / npm update).
• Apply codemods for template changes (coming soon).
• Re-run doctor to verify project health.

Version Migration

• Scaffold and mount a new API version alongside the current one:

node dist/cli.js migrate-version --to v2 --dir apps/my-api
# Creates: src/routes/v2/index.ts, mounts at /v2 in src/app.ts, updates .g1api.json

Notes:

• Valid versions: v<number> (e.g., v2) or vYYYY-MM (e.g., v2025-11).
• .g1api.json is updated with defaultApiVersion and multipleVersions: true when migrating.

API Configuration

• Projects include .g1api.json to track API versioning defaults:

{
  "defaultApiVersion": "v1",
  "multipleVersions": false
}

• Route generation respects defaultApiVersion unless overridden by --api-version.

Migrate Apply

• Align dependency ranges to match the template recommendations and bump template metadata:

npx @g1suite/api-cli@latest migrate --dir apps/my-api --apply

• What happens:
• Compares dependencies and devDependencies with the chosen template.
• Updates out-of-sync ranges and adds missing recommended deps.
• If g1-template.json exists, updates templateVersion to the CLI’s version.

Doctor Enhancements

• Doctor reports more detail about project health:
• Prints CLI version, detected template, and metadata status.
• Lists unchanged/changed/missing files against g1-template.json.
• Reports dependency alignment: out-of-sync and missing template recommendations.

Plugin System

• The CLI supports lightweight plugins to extend behavior for doctor and migrate.

• Plugins are discovered via either:

• api-cli.config.json at project root with { "plugins": ["<name>", "<name>"] }.

• package.json fields g1ApiCli.plugins or names starting with @g1suite/api-cli-plugin-.

• Plugin interface (TypeScript):

export type ApiCliPluginContext = {
  root: string;
  template: string | null;
  cliVersion: string;
  metadata: any;
  log: (msg: string) => void;
};

export type ApiCliPlugin = {
  name?: string;
  doctor?: (ctx: ApiCliPluginContext) => Promise<void> | void;
  migratePlan?: (ctx: ApiCliPluginContext) => Promise<void> | void;
  migrateApply?: (ctx: ApiCliPluginContext) => Promise<void> | void;
};

• Example plugin module:

// my-plugins/api-health-check.js
export default {
  name: "api-health-check",
  async doctor(ctx) {
    ctx.log("Plugin: running extra health checks...");
    // custom checks here
  },
  async migratePlan(ctx) {
    ctx.log("Plugin: suggesting additional steps for migration plan...");
  },
  async migrateApply(ctx) {
    ctx.log("Plugin: applying additional adjustments...");
  }
};

• Configure discovery via api-cli.config.json:

{
  "plugins": [
    "./my-plugins/api-health-check.js",
    "@g1suite/api-cli-plugin-example"
  ]
}

• Behavior notes:
• Plugin import failures are isolated and do not break the CLI.
• Each hook runs at the end of the related command, after core diagnostics.
• Use ctx.log for consistent output.
