Now let's make sure we have something to debug, so let's create an error in our print. However, in this post, we will be doing it from scratch. For that, you will need an IDE of your choice (considering WebStorm here, which already incorporates Node.js Express app generator). The first step is to create the new project and the project directory structure. Be sure to check them out so you can configure them to your needs.įor this guide, let's use the inline-source-map option, which is good for illustrative purposes (though not for production): Step 1: Creating Project Directory Structure.
There are a lot of different options available when it comes to source maps. If an error originates from b.js, the source map will tell you exactly that.

If you've been following the guides, you should have a solid understanding of some of the webpack basics. We mainly code in NodeJS and Angular and this was a perfect fit for. This guide extends on code examples found in the Output Management guide. We use IntelliJ Webstorm as the primary development editor for our development purposes.
