If your project doesn't have the file yet tsconfig. To get debug in TypeScript we need to enable source maps at compile time, this setting tells the compiler to generate a map file, which allows reverse engineering for the debugger to identify the exact line of code in TypeScript. Use a launch config to start your program, or attach to a process launched outside of VS Code. Use the JavaScript debug terminal, similar to using the integrated terminal. The debugger doesn't work automatically, so we need some settings to make it work. There are a few ways you can debug your Node.js programs in VS Code: Use auto attach to debug processes you run in VS Code's integrated terminal. In this tutorial we will learn how to debug typescript running directly on the machine, click here if you are looking for how to debug typescript with docker. Visual Studio Code supports the TypeScript debugger through its native JavaScript debugger. When we're in the development process, we spend a lot of our time 'debugging' the code and trying to figure out why it doesn't work or worse, why it works… The debug step is very important and can be very time consuming, so if we optimize this bug hunting, we optimize delivery time as well as quality.
