However, for most debugging scenarios, creating a launch configuration file is beneficial because it allows you to configure and save debugging setup details. To run or debug a simple app in VS Code, select Run and Debug on the Debug start view or press F5 and VS Code will try to run your currently active file. The top-level Run menu has the most common run and debug commands: If running and debugging is not yet configured (no launch.json has been created), VS Code shows the Run start view. The Run and Debug view displays all information related to running and debugging and has a top bar with debugging commands and configuration settings. You can also use the keyboard shortcut ⇧⌘D (Windows, Linux Ctrl+Shift+D). To bring up the Run and Debug view, select the Run and Debug icon in the Activity Bar on the side of VS Code. Once you have a simple application set up, this page will take you through VS Code debugging features. You can follow the Node.js walkthrough to install Node.js and create a simple 'Hello World' JavaScript application ( app.js). It is helpful to first create a sample Node.js application before reading about debugging. The following documentation is based on the built-in Node.js debugger, but most of the concepts and features are applicable to other debuggers as well.

Underneath ts-node this file got transpiled into JavaScript with tsc hello.ts, the TypeScript compiler and executed. It’s JavaScript disguised as TypeScript for now. $ npm install -g typescript ts-nodeĬreate a file called hello.ts. TypeScript comes with an execution and REPL for node.js called ts-node. I use nvm, whatever recent version of node and npm. Attempting a basic “hello world” in TypeScript turned out to be completely non-trivial, so this should help you. But I’ve never actually started anything in TypeScript. I’ve done a fair amount of JavaScript, here and there, and have written some TypeScript, too.
