# 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 `<target>` 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 <target> [file] # default: screenshot-<target>.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 <target> ``` ### Evaluate JavaScript ```bash scripts/cdp.mjs eval <target> <expr> ``` > **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 <target> [selector] # full page or element HTML scripts/cdp.mjs nav <target> <url> # navigate and wait for load scripts/cdp.mjs net <target> # resource timing entries scripts/cdp.mjs click <target> <selector> # click element by CSS selector scripts/cdp.mjs clickxy <target> <x> <y> # click at CSS pixel coords scripts/cdp.mjs type <target> <text> # Input.insertText at current focus; works in cross-origin iframes unlike eval scripts/cdp.mjs loadall <target> <selector> [ms] # click "load more" until gone (default 1500ms between clicks) scripts/cdp.mjs evalraw <target> <method> [json] # raw CDP command passthrough scripts/cdp.mjs open [url] # open new tab (each triggers Allow prompt) scripts/cdp.mjs stop [target] # stop daemon(s) ``` ## Coordinates `shot` saves an image at native resolution: image pixels = CSS pixels × DPR. CDP Input events (`clickxy` etc.) take **CSS pixels**. ``` CSS px = screenshot image px / DPR ``` `shot` prints the DPR for the current page. Typical Retina (DPR=2): divide screenshot coords by 2. ## Tips - Prefer `snap --compact` over `html` for page structure. - Use `type` (not eval) to enter text in cross-origin iframes — `click`/`clickxy` to focus first, then `type`. - Chrome shows an "Allow debugging" modal once per tab on first access. A background daemon keeps the session alive so subsequent commands need no further approval. Daemons auto-exit after 20 minutes of inactivity.
