Chrome Cdp

Lightweight Chrome DevTools Protocol CLI. Connects directly via WebSocket — no Puppeteer, works with 100+ tabs, instant connection. ## Prerequisites - Chrome (or Chromium, Brave, Edge, Vivaldi) with remote debugging enabled: open `chrome://inspect/#remote-debugging` and toggle the switch - Node.js 22+ (uses built-in WebSocket) - If your browser's `DevToolsActivePort` is in a non-standard location, set `CDP_PORT_FILE` to its full path ## Commands All commands use `scripts/cdp.mjs`. The `` is a **unique** targetId prefix from `list`; copy the full prefix shown in the `list` output (for example `6BE827FA`). The CLI rejects ambiguous prefixes. ### List open pages ```bash scripts/cdp.mjs list ``` ### Take a screenshot ```bash scripts/cdp.mjs shot [file] # default: screenshot-.png in runtime dir ``` Captures the **viewport only**. Scroll first with `eval` if you need content below the fold. Output includes the page's DPR and coordinate conversion hint (see **Coordinates** below). ### Accessibility tree snapshot ```bash scripts/cdp.mjs snap ``` ### Evaluate JavaScript ```bash scripts/cdp.mjs eval ``` > **Watch out:** avoid index-based selection (`querySelectorAll(...)[i]`) across multiple `eval` calls when the DOM can change between them (e.g. after clicking Ignore, card indices shift). Collect all data in one `eval` or use stable selectors. ### Other commands ```bash scripts/cdp.mjs html [selector] # full page or element HTML scripts/cdp.mjs nav # navigate and wait for load scripts/cdp.mjs net # resource timing entries scripts/cdp.mjs click # click element by CSS selector
