Mocking axios in Jest tests with Typescript
Recently I wanted to write a test for a React component that uses axios to retrieve information from an API. To do this I had to mock jest, but I ran into some issues with the types as I was using typescript. This article explains how I managed to get it to work.
Using GitHub Dependabot with a Monorepo
GitHub offers a dependabot service that can let you know of any potential security issues with your dependencies and automatically create a Pull Request for you. This works great without any configuration if you have a repo that contains npm, composer or gem dependencies, but you may need additional configuration if your lock files aren’t in the root directory, or in separate directories in the case of a monorepo.
What should I test?
You might often hear developers say that you should write tests. Great, let’s go! But what should you test and where do you start? I don’t know all the answers, but here are some tips for getting started.
Creating multi-worksheet Excel files with Simple Excel
Recently I had to create a large data export for a project. I like using Spatie’s Simple Excel package to do this as it is very simple to use and works well when exporting large amounts of data to a CSV or Excel file with the ability to stream a download to the browser. This particular project had an additional requirement though, exporting multiple worksheet’s of data at once. Luckily, this package allows you to do this too.
The PHP foreach loop
An alternative to the for loop, the foreach loop is used to iterate or loop over an array. The foreach loop allows you to loop through the items in the array without setting a limit for it to stop like you do in a for loop.
The PHP for loop

Testing window.open() in JavaScript with Jest
I recently had to write a test for a React component that opened a new browser window. To open the new window I made use of window.open() in my code. This made the component easy to write, but I had to think a bit differently about how to write the test for this.
Why did I become a writer?
There has been a lot of discussion on Threads recently about becoming a writer, but don’t give up your day job. I have seen a lot of arguments from all sides, some people saying they became a successful full time writer, others saying they would never give up their job, then there are others who became writers full time then went back to another job. Writing has always been a hobby for me, but this discussion has made me think more about why I write.
