# How to debug a SubQuery project?
# Video guida
In order to debug SubQuery projects such as stepping through code, setting breakpoints, and inspecting variables, you will have to use a Node.js inspector in conjunction with Chrome developer tools.
# Node inspector
Run the following command in a terminal screen.
node --inspect-brk <path to subql-node> -f <path to subQuery project>
node --inspect-brk /usr/local/bin/subql-node -f ~/Code/subQuery/projects/subql-helloworld/ Debugger listening on ws://127.0.0.1:9229/56156753-c07d-4bbe-af2d-2c7ff4bcc5ad Per aiuto, vedere: https://nodejs.org/en/docs/inspector Debugger allegato.
# Chrome devtools
Open up Chrome DevTools and navigate to the Sources tab. Note that clicking on the green icon will open up a new window.
Navigate to Filesystem and add your project folder to the workspace. Then open the dist > mappings folder and select the code you wish to debug. Then step through the code as with any standard debugging tool.
