Version 0.6.1 has broken build - missing browser.js and cli.js files

[hcentelles]

Bug Description

Version 0.6.1 published to npm has an incomplete build and cannot be executed. Critical source files are missing from the published package.

Error

Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/Users/username/.npm/_npx/.../node_modules/chrome-devtools-mcp/build/src/browser.js' imported from /Users/username/.npm/_npx/.../node_modules/chrome-devtools-mcp/build/src/main.js

Steps to Reproduce

npx -y chrome-devtools-mcp@latest

Root Cause

The published package is missing the following files that are imported by main.js:

• build/src/browser.js (imported at main.js:13)
• build/src/cli.js (imported at main.js:14)

Checking the published package structure:

ls ~/.npm/_npx/.../node_modules/chrome-devtools-mcp/build/src/

Shows these files are not present, while main.js attempts to import them:

import { ensureBrowserConnected, ensureBrowserLaunched } from './browser.js';
import { parseArguments } from './cli.js';

Impact

• Users cannot run version 0.6.1 via npx
• The package is completely non-functional

Workaround

Use version 0.6.0 which works correctly:

npx -y chrome-devtools-mcp@0.6.0

Likely Cause

The build script runs:

tsc && node --experimental-strip-types --no-warnings=ExperimentalWarning scripts/post-build.ts

The post-build.ts script likely failed or didn't complete properly during the npm publish process, resulting in an incomplete build/src directory.

Environment

• Node.js: v22.19.0
• Platform: macOS
• Tested versions:
  • 0.6.1: ❌ Broken
  • 0.6.0: ✅ Works
  • 0.5.1: ✅ Works

Hello,

I am unable the reproduce the issue locally. I also see that the files exits when searching on npm - https://www.npmjs.com/package/chrome-devtools-mcp?activeTab=code
Could you can try to clear the cache for npx by finding the folder for npm caches by running npm config get cache
and deleting the _npx folder under it, that will force npx to redownload the packages next time it's ran.

If the issue persist please leave a comment.
