Node has a wonderful debugger. As a front-end developer I’m mainly using Chrome’s tools but sometimes I run things in Node environment and this native feature comes handy. In this article we’ll see how to debug in the terminal using Node’s debugger.
I'm working on a small library that has a logger. I'm bundling the app to a single file and I want to disable the logger for the production version. In this blog post we will see how I removed the
logger.log calls from my bundle using AST (abstract syntax tree).
These days I had an interesting problem to solve. At work, on our staging environment, we have basic authorization. It works really well but for some older versions of Chrome we experienced a weird issue. The browser did not pass the authorization header. The app runs fine but as soon as it does a fetch request to a local endpoint the request fails with 401 not-authorized error. In the modern browsers that's not happening because the browser kinda knows that we came here with basic auth and automatically includes
authorization: basic ... header.
