![]() Copy this port number from the Debugger listening on. In this field, specify the port passed to -inspect, -inspect-brk, or -debug when starting the Node.js process to connect to. Either use the Open button on the Welcome Screen or choose Open from the File menu.In this field, specify the host where the application is running. Open your local TypeScript repo in WebStorm. Remember this is the compiler, so if the hello.js file was generated successfully then all is well and everything is working as it should. Don’t expect to see the output of the code. The output of the above command should be a hello.js file. I’m assuming your hello.ts file is in the examples directory and just one level up. Once that step is done - we can test out the compiler by running what’s below. npm install -g gulp npm installįinally to build the compiler - run gulp local Once you’ve changed into the TypeScript directory, install Gulp.js if you don’t already have it. Instructions to build the TypeScript compiler are included in the README.md but here’s what you mainly need to do. You preferably want this in another directory and not in the same directory you created in the previous step. interface Person Clone and Setup the TypeScript repoĬlone the TypeScript repo from and follow instructions to set it up. mkdir examples & cd examplesĬreate a new file called “hello.ts” and paste in the below code. It does not matter what the folder is called so feel free to change “examples” into whatever suits you best. ![]() The typescript compiler needs to be transpiling something to hit breakpoints and do its thing.Ĭreate a folder and change into it. If you already have typescript code you want to work with, there is no need to set up a hello world project. Optional: Setup HelloWorld Typescript project. Getting breakpoints to work within TypeScript compiler source code If everything was done correctly, you should now be able to set breakpoints in your TypeScript code and hit them via the debugger. Add the generated index.js or main.js file in the output folder in the javascript file field. Add the output directory as working directory in the modal that pops up. In the Run > Edit Configuration window, click the + sign and choose Node.Js option. The output directory is where the generated js files are located. The tsconfig.json file should mention an outfile or output folder. Add "sourceMap":true in the compilerOptions section of your tsconfig.json file. General steps to set up debugging for server-side TypeScript Applications To debug TypeScript using Visual Studio Code: In case you’re looking to debug client-side applications written using TypeScript, check out: I’ll have to do a future blog post detailing problem-solving and debugging a standard TypeScript node js project. Those two are not exactly the same but for some reason, I was tempted to spend time stepping through the TypeScript project to checkout TypeScript internals. The instructions in this post should work if you’re looking to debug the TypeScript compiler itself or your node js project that uses TypeScript. This blog post shows you how to go about setting up the debugger in WebStorm for server-side TypeScript projects. Another way of looking at it, if you can pretend the “Any” type does not exist, TypeScript almost feels like a strongly typed language. TypeScript a typed superset of Javascript. The world seems to be moving towards using TypeScript with Node.js.
