Summary

AI summary

Fixed vurb deployment module resolution bugs and added a CLI token command.

Full changelog

Fixed

  • vurb deploy — Cannot find module 'vurb' (Bug #151) — Three cascading bugs:

    1. require.resolve('vurb') — package is @vurb/core
    2. require.resolve('@vurb/core') — exports map is ESM-only, CJS resolution fails
    3. esbuild alias — prefix matching turns fs/promises into edge-stub.js/promises

    Fix: esbuild plugin (onResolve + onLoad) with CJS Proxy catch-all.
    Uses builtinModules from node:module (dynamic, future-proof).
    Known exports (EventEmitter, Buffer, etc.) resolve normally.
    Unknown names (readFile, createServer, etc.) return CRASH function.

  • token.ts exactOptionalPropertyTypes compliance

  • Dead dirname import in deploy.ts

Added

  • CLI token command — vurb token, vurb token --clear, vurb token

Test Suite

  • 19 regression tests in deployEdgeStub-bug151.test.ts including:
    • 2 real esbuild integration tests (17 node:* imports including subpaths)
    • Regex coverage for ALL builtinModules
    • Source analysis and compiled output verification
