What are the steps to troubleshoot server-side TypeScript code in NextJS with WebStorm?

I am struggling to debug the NextJS API in WebStorm while using TypeScript and navigating through the app route. It is proving to be quite challenging to efficiently debug the API without relying heavily on console.log().

Answer №1

If you want to set up debugging for Next.js in WebStorm, follow these steps:

  1. To begin, go to the Run > Edit Configurations... dialog within WebStorm.
  2. Next, click on the + button to create a new configuration and choose Node.js.
  3. Provide a descriptive name for your configuration, like “Debug Next.js with Yarn”.
  4. In the Working directory section, select the main directory of your Next.js project.
  5. Instead of linking directly to a file in the JavaScript file field, you will use the Yarn command. Configure the Node interpreter to point to the Node.js binary path, and enter the Yarn binary path (usually /usr/bin/yarn or just yarn if it's in your system’s PATH) in the Node parameters field.
  6. Type dev in the Application parameters field to run Next.js in development mode.
  7. Finally, confirm the setup by clicking OK.
