npm 12 + Puppeteer: Chrome Missing After Install

adityahalder — Thu, 27 Aug 2026 07:39:57 +0000

npm 12 can skip Puppeteer’s browser download while npm install stays green. Reproduce it, approve one pinned package, rebuild, and verify

Originally published at CodeReport Global — read the full guide with code, screenshots and benchmarks at https://codereportglobal.indevs.in/articles/npm12-puppeteer-chrome-missing.

Why this matters

npm install can finish successfully under npm 12 while Puppeteer still has no browser to launch. That is the failure boundary this article covers—not npm 12 in general, and not a generic Puppeteer tutorial. In a disposable fixture using Node 22.22.2, npm 12.0.2, Puppeteer 25.9.0, and an isolated Puppeteer cache,…

TypeScript 7 ESLint: Safe TS6/TS7 Setup

adityahalder — Wed, 26 Aug 2026 06:40:46 +0000

Keep ESLint stable while adding TypeScript 7: use the side-by-side npm aliases, CI checks, failure diagnosis, verification, and rollback

Originally published at CodeReport Global — read the full guide with code, screenshots and benchmarks at https://codereportglobal.indevs.in/articles/typescript-7-eslint.

Why this matters

TypeScript 7 is a compelling compiler upgrade, but it is not a drop in replacement for every tool in a TypeScript repository. TypeScript 7.0 does not ship with a programmatic API, while typed ESLint and other ecosystem tools still need compiler APIs. The production safe pattern is to keep TypeScript 6 under the…

How to Sandbox Claude Code Without Breaking Git and MCP

adityahalder — Tue, 25 Aug 2026 04:56:30 +0000

Learn which Claude Code sandbox protects Bash, MCP, hooks, Git, and credentials, with Docker and VM trade-offs and safe verification steps.

Originally published at CodeReport Global — read the full guide with code, screenshots and benchmarks at https://codereportglobal.indevs.in/articles/claude-code-sandbox.

Why this matters

If I want Claude Code to work with fewer permission prompts, I should not treat every sandbox option as the same control. Anthropic’s built in Bash sandbox limits Bash commands and their child processes, but its built in file tools, MCP servers, and hooks still run on the host. A stronger choice—Anthropic’s sandbox…

Why AI-Built Websites Break During Deployment: 15 Fixes

adityahalder — Mon, 24 Aug 2026 04:54:38 +0000

Fix AI-built websites that fail deployment, show 404s, lose assets, or break in production with 15 proof-driven checks for Vercel, Netlify,

Originally published at CodeReport Global — read the full guide with code, screenshots and benchmarks at https://codereportglobal.indevs.in/articles/ai-deployment-fixes.

Why this matters

An AI built website usually breaks during deployment because the generated code assumes local conditions that do not exist in production: the host may use a different Node.js or package manager version, build from the wrong directory, publish the wrong output folder, omit a scoped environment variable, reject a…

What should you check before changing generated code?
How do you prove the failure locally before touching the host?
Why can a successful build still produce a blank page or 404?

AI Code Passes Tests but Fails in Production

Why this matters

A green test suite does not prove that AI generated code is production safe. It proves only that the tested inputs produced the expected results under the tested environment and assumptions.

How to Install Rust Glancer in VS Code

adityahalder — Sun, 23 Aug 2026 09:53:03 +0000

Install Rust Glancer in VS Code with rust-src, configure its server path, verify indexing, and understand its memory and rust-analyzer trade

Originally published at CodeReport Global — read the full guide with code, screenshots and benchmarks at https://codereportglobal.indevs.in/articles/rust-glancer-vscode-setup.

Why this matters

Rust Glancer can be installed in Visual Studio Code by adding the mandatory rust src component, installing the Rust Glancer extension, and making sure the rust glancer server is available on PATH or configured with an absolute path. It is an experimental, low memory Rust Language Server Protocol implementation—not a…

npm 12 Install Scripts Not Running: Fix better-sqlite3

adityahalder — Sun, 23 Aug 2026 08:52:27 +0000

Fix npm 12 install scripts blocked for better-sqlite3 and node-gyp. Review allowScripts, rebuild safely, and verify the native binding.

Originally published at CodeReport Global — read the full guide at https://codereportglobal.indevs.in/articles/npm12-install-scripts.

On August 23, 2026, I reproduced the npm 12 failure mode that is easy to miss: npm install can exit with code 0 while blocking a dependency’s lifecycle script. If that script builds a native addon, downloads a platform binary, or generates a required file, the application can fail later even though the installation looked successful. npm 12 blocks dependency preinstall, install, and postinstall scripts by default through the root project’s allowScripts policy, and it treats an implicit node-gyp rebuild as an install script. The safe repair is not to disable script protection globally. In the p…
