SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

CLI tooling that translates complex Next.js and React internals into accessible, structured shell output, enabling quick exploration of component trees, props, hooks, errors, and network activity without a GUI.

Core Features & Use Cases

  • Exposes a comprehensive command set (open, goto, perf, renders, tree, network, errors, logs, ppr, ssr lock) to inspect app state from the terminal.
  • Enables debugging, performance profiling, and regression checks by capturing hydration, re-renders, and server rendered shell data.
  • Useful for CI and local development to quickly audit architecture, diagnose rendering issues, and verify route boundaries.

Quick Start

Install next-browser globally, then run next-browser open http://localhost:3000 to inspect a page.

FAQPage Schema
How do I inspect a React component tree from the command line?

Inspecting a React component tree from the CLI involves running shell commands that expose component trees, props, and hooks as structured terminal output. This tool translates Next.js and React internals into accessible shell data without requiring a GUI.

Can I profile Next.js app performance in a CI pipeline without a browser GUI?

Yes, profiling Next.js performance in CI pipelines without a GUI is possible by running shell commands that capture hydration, re-renders, and server-rendered data. It uses Playwright-based browser automation to output structured performance metrics to the terminal.

What is the best way to debug Next.js hydration errors via terminal?

Debugging Next.js hydration errors via the terminal is best done using a CLI tool that captures errors, network activity, and logs as structured shell output. It enables rapid diagnosis of rendering issues and verification of route boundaries during local development.

Does this React debugging CLI require Playwright or Node-based tooling?

Yes, this React debugging CLI relies on Node-based tooling and Playwright-based browser automation to function. It requires a YAML frontmatter in SKILL.md and uses these dependencies to inspect app state and expose it as structured shell output.

How do I view network activity and logs for a Next.js app in the shell?

Viewing network activity and logs for a Next.js app in the shell is done by executing specific CLI commands like 'network' and 'logs'. These commands inspect app state and return structured terminal output for rapid debugging and profiling.

When should I not use a CLI tool for React component debugging?

Using a CLI tool for React component debugging is not suitable if you require visual GUI interactions or lack a Node-based environment. This tool is designed for terminal-based structured output, CI pipelines, and automated checks rather than visual exploration.
