@livon/cli

npm Package Size Security Scorecard CI

Purpose​

CLI for syncing schema AST from a running server and generating/updating client outputs.

Best for​

Use this package when you want generated client APIs to stay in sync during local development and CI.

Install​

pnpm add -D @livon/cli

Recommended command (sync + app)​

livon \
  --endpoint ws://127.0.0.1:3002/ws \
  --out src/generated/api.ts \
  --poll 2000 \
  -- pnpm dev

Generated output mode​

livon always runs in rslib mode after sync.

  • default output: esm + cjs + d.ts
  • use --esm or --cjs to build only the selected format
  • use --js when you only need esm + cjs and want to skip declaration files

With --out src/generated/api.ts, compiled files are written to src/generated/dist. livon also writes src/generated/package.json with conditional exports, so import { api } from './generated' resolves to the matching build output.

Linked process lifecycle​

If the linked command exits, livon exits too.
If livon exits, it terminates the linked command.

If your linked command starts with flags, use -- before it:

livon --endpoint ws://127.0.0.1:3002/ws --out src/generated/api.ts -- --some-command --flag

Parameters​

  • --endpoint <ws-url> (string): websocket endpoint used to fetch schema explain data (required unless --port is used).
  • --port <number> (number): overrides endpoint port when endpoint host/path stay unchanged.
  • --out <file> (string): output file path for generated API module.
  • --poll <ms> (number): polling interval for repeated sync runs.
  • --timeout <ms> (number): request timeout per sync call.
  • --event <name> (string): schema explain event name (default: $explain).
  • --method <GET|POST> (string): request method for explain fetch.
  • --header key:value (string, repeatable): additional request header.
  • --payload <json> (string): raw JSON payload body for explain request.
  • --esm (boolean): build only ESM output (dist/index.js).
  • --cjs (boolean): build only CJS output (dist/index.cjs).
  • --js (boolean): builds only esm + cjs (skips .d.ts output).
  • --no-event (boolean): disables event wrapping behavior for transports expecting plain request mode.
  • -- (delimiter): separates livon flags from linked command arguments.

Typical workflow​

  1. Start server with schemaModule(..., { explain: true }).
  2. Run CLI in watch/poll mode during client development.
  3. Use generated API module in the client runtime.
