![]() ![]() 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. This configuration will definitely help you get started understanding the framework and squashing those pesky scripting bugs.The world seems to be moving towards using TypeScript with Node.js. This debug configuration may be obvious to a seasoned node developer, but if you’re a language transplant like me, you may need help getting started with debugging serverless using WebStorm. If you launch the Configuration as debug, the WebStorm debugger will automatically be hooked into the node process. Be sure to add any additional parameters you might need such as ‘-s local’.If you do not know where sls is installed you can find it by typing which sls in the terminal JavaScript file: this should point to the serverless binary: Typically /usr/local/bin/sls.Be sure it points to the directory with your serverless.js file Working directory: This will default to the root of your project.Create a new node configuration by click + and then Node.js from the dropdown Create a new node configuration: In the toolbar click Run –> Edit Configurations…Ģ.Some locations may vary depending on your OS. For the purpose of this tutorial, we will be using macOS Mojave. There are a ton of tutorials on how to install node, serverless, WebStorm, so I’ve assumed you’ve already taken care of that. The following will get you started debugging node serverless using JetBrains WebStorm. When I went looking how to debug serverless, I struggled to find a solution that detailed debugging serverless in JetBrains WebStorm. Recently I was working on a Node serverless project and had no idea what fields existed on the serverless lambda objects (event, context, callback). I find the ability to profile data structures to be extremely useful when working with scripting languages such as Python and Node. The debugger allows a developer to not only step through code and track down bugs, but it is useful as a way to profile data structures. One of the most useful tools in a developer’s quiver is the debugger. ![]()
