href="#debugger_v8_inspector_integration_for_node_js">V8 Inspector</a> and built-in debugging client. To use it, start Node.js with the <code>inspect</code> argument followed by the path to the script to debug; a prompt will be displayed indicating successful launch of the debugger:</p> <pre><code class="language-txt">$ node inspect myscript.js < Debugger listening on ws://127.0.0.1:9229/80e7a814-7cd3-49fb-921a-2e02228cd5ba < For help, see: https://nodejs.org/en/docs/inspector < Debugger attached.

It uses the <a href="https://chromedevtools.github.io/devtools-protocol/">Chrome DevTools Protocol</a>.</p> <p>V8 Inspector can be enabled by passing the <code>--inspect</code> flag when starting a Node.js application. It is also possible to supply a custom port with that flag, e.g. <code>--inspect=9222</code> will accept DevTools connections on port 9222.</p> <p>To break on the first line of the application code, pass the <code>--inspect-brk</code> flag instead of <code>--inspect</code>.</p> <pre><code class="language-txt">$ node --inspect index.js Debugger listening on 127.0.0.1:9229.
