This week, we’ve got a new Node API that was years in the making, Vercel hiring Kendrick Lamar, and a makeover for my mommy blog. Welcome to #86.
The tables have turned
They did it. The Node.js team finally made fetch happen.
fetch API makes it easy to make HTTP requests. Before
fetch, we had to use the “butterfly” of the dev world,
XMLHttpRequest. Despite their names, butterflies aren’t made out of butter and
XMLHttpRequest can be used to retrieve any type of data, not just XML.
fetch simplifies that process with a minimal Promise-based API, which is built on primitives like
Response that represent parts of the HTTP request lifecycle. It’s been around for a while — we’ve had
fetch in browsers since 2015, and Deno’s had it since 2019.
So what took Node so long? And why now?
Turns out, browsers and Node are not alike at all. Features that already exist in browsers needed to be re-created in Node — like
FormData… you get it. And things that browsers take for granted, like “the origin” (aka the website making the HTTP request), don’t make sense in a server environment. Same goes for lots of browser security features.
So yeah, it’s a lot of work. Adding a browser-first API like
fetch to Node is kind of like adding an open bar to your family reunion — it seems like a simple enough way to amp up the fun, but if you haven’t put in the time to figure out all the logistics, things will get very complicated very quickly.
Why Now? The
fetch addition was finally made possible by
http, Node’s existing HTTP client. In 2018, the Node.js team started an effort called undici (Italian for eleven) to modernize and improve
http. Undici uses Promises, which enables async/await, and is 14x faster than the existing API.
It’s literally taken years to implement everything needed in both Node core and undici, but it’s finally done. Last week, undici and its built-in
fetch API were merged into Node.js core. You can use it when Node 18 comes out in April.
Bottom Line: Having
fetch in Node is kind of a big deal. It provides a standard around fetching data that’s the same as browsers, which brings us one step closer to being able to use server code and client code interchangeably. Still upset about butterflies though.

…for your code. Now stop looking at me like that.
Raygun has super powerful tools that make it easy to get all the diagnostics you care about for your team’s web and mobile apps. When there’s an issue, it shows you exactly what’s going on, who’s being impacted, and exactly how to fix the root cause – down to the specific line of code itself.
This X-Ray Code Vision lets you quickly prioritize fixing the issues that have the biggest impact on your users, so that you can quickly return to watching Spider-Man 3 starring Tobey Maguire (aka the greatest film of the 21st century).
Start a 14-day free trial of Raygun and give your team a tool that’ll genuinely make their lives easier. It only takes a few lines of code, and their simple usage-based plans start at $4 a month – a small price to get your users to love you, your team to love you, and your stepdad to finally respect you.
Try it out. Thank me later.
First we gonna rock, then we gonna roll
Everyone’s favorite tool for
over-engineering your blog inserting cool components into long-form content just got even better last week. I’m talking about MDX — the aptly named lovechild of markdown and JSX that just released v2.
This release comes 2.5 years after v1 was released, and it required almost a complete rewrite. Let’s dive into the highlights:
Rollup and esbuild join the party — MDX used to only work with Babel and webpack, but now it’s got integrations for hot new build tools like Rollup and esbuild. You can also import MDX files directly in Node.js with the new
Bottom Line: This release should make MDX even more popular as it spreads its non butter wings beyond the React ecosystem. And it’s definitely going to revolutionize the mommy blog I’ve been ghostwriting about gourment Italian food for the whole family. My affiliate links for this Amazon Basics dutch oven will be popping off once I seamlessly embed an interactive image of it in the middle of my World’s Best Baked Ziti recipe — which obviously begins with 20,000 words about the history my family, the etymology of the word “ziti”, and a quick breakdown of all the cool new features in MDX 2.
Storybook lets you pinpoint visual bugs automatically. Chromatic runs visual tests, publishes component docs and gathers UI feedback in one shared workspace. That helps you ship UIs with less manual work. Learn more » [sponsored]
Vercel released a very aesthetically-pleasing 2021 Year in Review. The best part was where they talked about how they hired Kendrick Lamar. Or maybe they just meant that a web developer built him a website with Next.js (??). Either way, you know that growth chart has Guillermo saying, Now I run the game, got the whole world talkin’.
There was a little bit of an uproar last week when it was revealed that nobody at Facebook has worked on Jest for years. Honestly based on their stock price lately, it feels like making fun of Meta is punching down for us now, so we’re going to stop.
Electron 17 was just released with some stack upgrades and a couple small breaking changes. “bUt iSn’T iT SoOOo bIg ANd sLOw??” Maybe, but the hand full of billion dollar companies built on it don’t seem to mind.
Gyroflow is a new Rust app for stabilizing video using motion data from a gyroscope, because Rust is everywhere and we cannot escape it.
