Debug Node.js Typescript app using VS Code (Mac,Linux)

#typescript #linux #node #javascript

Using the following configuration I managed to debug flawlessly Node.js applications written in Typescript using the Visual Studio Code IDE. I have tested it on Mac OS and almost every Linux distro like Debian, Ubuntu, Arch.

Configure tsconfig.json

First of all, enable source maps "sourceMap": true and declarations "declarationMap": true, "declaration": true.

Don't forget to specify the destination folder using the outDir parameter.

Configure VSCODE

Paste the following snippet and change __MYAPP__ to the typescript file you want to debug and __MYDIST_FOLDER__ to the dist folder of your project.

Don't forget to whitelist (OUTPUT) port 9229 locally on your iptables.

Examples:
__MYAPP__ = src/app.ts
__MYDIST_FOLDER__ = dist
