Published packages set exports["."].bun to ./src but ship only dist/ — breaks all Bun consumers

[amondnet]

Summary

Every published service package sets exports["."].bun to a ./src/* entry, but the npm tarballs ship only dist/ ("files": ["dist"]). Because Bun resolves the "bun" export condition first, any Bun consumer that installs these packages from npm fails with Cannot find module. The ./dist/index.js file exists in the tarball but is unreachable, since the exports map declares no subpath for it either.

This affects the whole registry surface, not a single package.

Affected packages (all 0.1.0)

All of the following declare "bun": "./src/index.ts" (or ./src/api.ts) while publishing only dist/:

• @pleaseai/emulate (bun: ./src/api.ts)
• @pleaseai/emulate-asana
• @pleaseai/emulate-autumn
• @pleaseai/emulate-firebase
• @pleaseai/emulate-gitlab
• @pleaseai/emulate-kakao
• @pleaseai/emulate-linear
• @pleaseai/emulate-naver
• @pleaseai/emulate-posthog
• @pleaseai/emulate-spotify
• @pleaseai/emulate-supabase
• @pleaseai/emulate-toss-payments
• @pleaseai/emulate-workos
• @pleaseai/emulate-x

Reproduction

mkdir /tmp/repro && cd /tmp/repro && bun init -y
bun add @pleaseai/emulate-asana @emulators/core
echo "import { asanaPlugin } from '@pleaseai/emulate-asana'; console.log(typeof asanaPlugin)" > run.ts
bun run.ts

Actual:

error: Cannot find module '@pleaseai/emulate-asana' from '/tmp/repro/run.ts'

A deep import (@pleaseai/emulate-asana/dist/index.js) also fails, because the exports map exposes no ./dist/* subpath.

Root cause

packages/*/package.json:

{
  "exports": {
    ".": {
      "bun": "./src/index.ts",   // <- not in the published tarball
      "types": "./dist/index.d.ts",
      "import": "./dist/index.js"
    }
  },
  "files": ["dist"]              // <- src/ is never packed
}

Verified against a published tarball — no src/ is present:

$ npm pack @pleaseai/emulate-linear@0.1.0 && tar -tzf pleaseai-emulate-linear-0.1.0.tgz
package/dist/index.d.ts
package/dist/index.js
package/package.json

The "bun" condition is meant to let in-repo development resolve TypeScript source directly, but that path leaks into the published package, where src/ does not exist.

Suggested fixes (any one resolves it)

1. Point bun at the built output in the published package — e.g. drop the "bun" condition entirely so Bun falls through to "import": "./dist/index.js", or set "bun": "./dist/index.js". Simplest and matches what other conditions already resolve to.
2. Use publishConfig.exports to override the exports map at publish time (keep ./src for local dev, publish ./dist). This preserves the source-resolution DX in-repo while shipping a correct map.
3. Ship src/ too — add "src" to files. Works, but bloats the tarball and publishes TS source unnecessarily; options 1/2 are preferable.

Workaround for consumers (until fixed)

Patch the installed exports.bun to the shipped dist. With Bun:

bun patch @pleaseai/emulate-asana@0.1.0
# edit node_modules/@pleaseai/emulate-asana/package.json:
#   "bun": "./src/index.ts"  ->  "bun": "./dist/index.js"
bun patch --commit node_modules/@pleaseai/emulate-asana

Environment

• Bun 1.3.14
• @pleaseai/emulate-*@0.1.0, @emulators/core@0.6.1
