Bits and bytes of code

If you use TypeScript, you've more than likely seen keyof typeof obj at one point or another to get a union type representing the keys of the given object. But what if we want to get a subset of the object keys, based on the values in the object?

Earlier last year, I created a tool called Flashlight which is a Rust-powered JavaScript code search tool. I recently added support for searching for JSX tags and I'd like to highlight the features of Flashlight briefly.

I recently published a new library that is an extremely minimal dependency injection library: TiDI. It has an intentionally small feature set and is designed specifically for class-based dependency injection

Taking screenshots is a common task when working on an engineering team. Sharing in-progress work, showing bugs or needed changes, or finding design inspiration from another web app. While often you just want to send a message with the screenshot, sometimes it's helpful to save them to disk for later use.

In a previous Byte, I showed the useStrictParams hook as a way to better manage React router params with better type safety and ease of use. Since then, I've made some improvements and published it to npm!

If you've ever created custom link styles to show on hover to replace the rather dull underline that is the default behavior for links, you may very well have encountered issues when links begin to wrap across multiple lines. Thankfully, CSS has a solution to this with a fairly obscure property: box-decoration-break.

ffmpeg is a fantastic tool for converting videos between various formats. I recently needed to create a GIF from a screen recording, which you can do with ffmpeg, but the command isn't the easiest to remember.

The useParams and useSearchParams hooks from React Router are critical when working with dynamic routes, however they have some sharp edges when used with TypeScript. With a small amount of additional code, we can make it much easier to work with params.

I came across the document.designMode property recently, and at first I did not understand why you would ever need it, but today I actually used it and wanted to share my learnings with you!

Old Git branches that are already merged can very quickly clutter your local repository. This can make it more difficult to find active branches you are working on. With a simple shell script we can clean up these old branches.
