30秒学会 JavaScript 片段 – Debugging Node.js using Chrome Developer Tools

Node.js can be debugged using Chrome Developer Tools since v6.3.0. Here’s a quick guide on how to do this:

1. Download and install Node.js v6.3.0 or newer, if you don’t already have it installed on your machine.
2. Run node with the --inspect-brk flag (e.g. node --inspect-brk index.js).
3. Open about:inspect in a new tab in Chrome. You should see something like the screenshot below.
4. Click Open dedicated DevTools for Node to open a new window connected to your Node.js instance.
5. Use the Developer Tools to debug your Node.js application!
