Imagine that you’ve been doing a bunch of research, and you’ve decided to structure your team’s component library as a monorepo. You’re probably feeling excited — you’ve finally made a decision! And then it hits you — now you have to make another decision: Do you write custom scripts to manage…

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…

A blog post to accompany my talk for Figma on using the concept of progressive disclosure of complexity to guide multi-brand design system architecture

If you’re anything like me, there are few things as frustrating as when you need to customize a third-party component’s styles and you just cant. Now that I’m actually working on building a component library myself, I want to share with you how you can build components that can be overridden and how…

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.

We can use Lerna with Yarn Workspaces develop across multiple components without having to publish them to a registry or rely on `yarn link`.

If you're going to build a component library, you need to decide how to store your components. Most teams choose between two options: you can store each component separately in its own repo, or you can store all of your components together in a monorepo.

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…

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…

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.

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…

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…

React 16.6.0 introduced , which allows you to code-split using the new Suspense API. Siddharth Kshetrapal came out with a great video showing how this works in 60 seconds. I’d recommend watching it –– it’s really well-done. I’ve built a Github clone based off of Siddharth’s example. Hopefully this…

The React ecosystem offers multiple ways to pass data and manage state in a client-side application. A developer might choose between prop drilling, redux, MobX, and the new Context API introduced in React 16 depending on the size and complexity of the application they are developing. A developer…

Modular frontends are all the rage these days, especially with the rise of React.js. Large companies have begun open-sourcing their frameworks,. Google has Material UI, Shopify has Polaris, and Palantir has Blueprint. You, (or your boss), might be thinking that it’s time for your company to get in…

Developers tend to have opinions on style. If you’ve been in the industry for more than 15 minutes, you’ve at least heard about the arguments over spaces or tabs. And don’t even get me started on whether JavaScript needs semi-colons or not. That’s where automatic code formatting comes in. Sure, when…

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…

I built the same program 4 different ways. I started with callbacks, moved on to Promises, used generators, and finished up with async/await. The program: Makes a request to Github’s users endpoint Pulls back my Github profile Logs the response Here’s what I came up with. Callbacks I struggled to…

You can find part 2 here, and part 3 here. This series will walk you through how to make HTTP requests to the Github REST API in React.js. I’ve chosen the Github API because it is well-organized and doesn’t require us to do any sort of authentication. Part 1 will focus on setting up a React…

If you haven’t completed part 1 of this tutorial, do so before starting part 2. Now that we’ve set up our project using create-react-app, we can start writing some code. Open your project into your editor of choice, and let’s start removing some of the boilerplate that create-react-app adds for you…

If you haven’t completed part 1 and part 2 of this tutorial, please do so before starting part 3. Now we’re getting to the good part! So far, we’ve set up a new React application using , and we’ve wired up our component to log ‘Success!’ when we click the button. Now, we need to make the actual HTTP…

Hoisting remains one of the quirkier aspects of JavaScript. When a developer declares a variable in JavaScript, that variable *behaves *as if it’s been lifted to the top of it’s available scope. This article isn’t going to concern itself with what actually happens behind the scenes to cause this…

Eric Elliot, in his Medium article Master the JavaScript Interview: What is a Closure?, explains that when he interviews candidates for JavaScript jobs, he always asks questions about closures. He writes: “I don’t care if a candidate knows the word “closure” or the technical definition. I want to…

Before you begin, make sure you have node and npm installed. Use a node version higher than 6. Also, note that all terminal commands are for Mac. Please use the equivalent commands for your OS. The repository for this tutorial lives here The other day I was setting up a D3.js project when I ran into…
