How to switch npm registries
August 10, 2020
What is a registry? I like to think of a registry like a brick-and-mortar library. When you go to the library, you can check out books that you’d like to take home. Some libraries are public while others are private. If you’d like to check out a book from a private library, you need special…
A short explanation of semantic versioning
August 10, 2020
Semantic versioning is a way for library authors to communicate to consumers that you’ve released a new version and information about the kind of version you’ve published.

July 26, 2020
Early on in my career, I found myself at a total loss about the command to start a new project’s development server. At my first job, we used the script to run the app. I tried to run on this new project, but it just wouldn’t work. I felt embarrassed that I couldn’t figure out how to run the app…

4 tools to help you version your component library
July 07, 2020
As I've been wandering around the internet during quarantine, I've noticed a lot of people asking about how to version a component library. It seems like devs who are starting to work on component libraries understand that they should version their libraries, but they're not sure where to start.
Are you struggling to make sense of whether you should version your components as a unified system, like Babel or to version them separately, like Gatsby? Well, you’re certainly not alone. It can seem like there really is no right answer, and you might even start wondering why you need to version…

Reduce Friction with Automated Package Generation
April 05, 2020
When you’re working on a component library for your organization, you want your teammates to contribute. If your teammates aren’t contributing to your efforts, it could mean a couple of different things. They don’t believe in the initiative or don’t understand the value of component libraries It’s…

Design tokens are an approach to storing style attributes like color, typography, and spacing in a pre-determined structure. They are an alternative to directly hard-coding style data that allow designers and developers to build consistent, pleasing layouts, quickly accomplish redesigns, and add a theming layer to their applications.

Use your CI Pipeline to Address Security Vulnerabilities
January 12, 2020
When leveraging the npm ecosystem, you inevitably add dependencies to your codebase. That’s great –– we’re lucky to have a robust open-source culture. Strangers have solved many problems you might run into! But there’s a catch…all the libraries you depend on are bound to evolve, which means you need…

In this post, I’m using vim. But you can use a different editor if you want! You’ll need to figure out how to use your editor as your machine’s default git commit/diff tool. You can find instructions for configuring this with VS Code here. Developers have different opinions about whether to rebase…
Using node-fetch with apollo-link-http
May 23, 2019
I’m building a Gatsby app that consumes data from a GraphQL service with the help of apollo-client and TypeScript. Because Gatsby creates static assets at build time, I needed a data-fetching tool that would work on the client-side and the server-side. apollo-client recommends using node-fetch for…
Before You Build A Component Library: Versioning

Versioning is one of the most challenging aspects to building and maintaining any library. It's also one of the most crucial. If you want people to use your library, you need to worry about versioning.
useBreakpoints: a hook
February 15, 2019
I built my first hook a few months ago, and figured I should get it up on the blog. It’s a replacement for a Higher Order Component that exists in a codebase I’m working on. That HoC passes a breakpoint to a component that dictates how the component renders across different breakpoints. If you want…
Why you should avoid the --parallel flag in lerna build scripts
February 15, 2019
When you’re configuring a monorepo with lerna, you might consider writing your build scripts like this: It makes sense, initially! You’re probably thinking, why wouldn’t I want to build all my scripts concurrently, rather than running each build one-by-one? The above build script actually works…
How to use React.Lazy

Shining a Spotlight on Error Boundaries in React 16
December 20, 2017
React 16 has better error handling than previous React versions. If an error occurred inside of a component, it would “corrupt React’s internal state.” Then, we would end up with “cryptic” error messages, or just a blank screen. React lacked a way to expressively and eloquently handle these errors…
