The next chapter of MSW is here!
I'm excited to announce MSW v3.0! 🥳
- Leaner dependency graph and smaller size;
- ESM-only;
- Granular entrypoints;
- GraphQL subscriptions;
- Socket-based network interception in Node.js;
- And much more!

It surprises me how many developers miss the point that you can (and should) generate your handlers in MSW from actual API contracts, like OpenAPI! That *is* the way to drift-free mocking.
Please spread the word: mswjs.io/ecosystem/source/
Thank you.

I am beyond thrilled to welcome @beehiiv as MSW partner! Their support makes sure I can keep working on better API mocking for everyone. Thank you ❤️

Integrating MSW into Vite-based projects has become silly simple with the new "msw/vite" plugin! And yes, this works with Vitest, too.
The plugin integrates MSW client and server-side and keeps the worker script up-to-date for you, automatically.

Realized I forgot to add the GraphQL subscriptions docs 🤦♂️ Injustice fixed. I present to you the beauty which is mocking GraphQL subscriptions: mswjs.io/docs/graphql/interc…
Help shape the future of API mocking on the web.
With MSW 3.0 released this week, I want to try something new to make the project financially sustainable. I wrote an open letter about the project, its history, and impact on the ecosystem.
I ask for five minutes of your time to read it. Thank you.

You don't have to sponsor to help.
Consider nominating MSW for the Open Source Endowement fund: endowment.dev/funding/
Thank you!
I am losing roughly $800 a month by working on MSW full-time while it's one of the most used projects in the ecosystem. Please, if MSW provides you any value, consider becoming a sponsor. I mean it when I say every contribution counts.
Thank you ❤️

Come learn component testing from me in person! Accessibility-first, beautifully set up, and running in a real browser with Vitest. One of my best selling workshops on Epic Web now live.

MSW add-on for Storybook is downloaded 1,539,807 times per week! That makes it one of the most used add-ons in the entire Storybook ecosystem. Pretty wild.
And with the latest release, it's the best way to mock the network in your stories, too.

If you let your agent write component tests for you, you're in BIG trouble. Why? Because agents were trained on prehistoric tests still using JSDOM.
Yikes 🤢
Join me on 📆 October 5th in 🇨🇿 Prague for a live workshop to learn component testing in the real browser with Vitest.

Just got MSW CI builds from 10m to 1m thanks to @useblacksmith. Absolutely insane, look at this.
Also a significant boost after migrating most tests from Playwright to Vitest Browser Mode. It proves times faster for me in every project.

Hold on, what if...?

MSW hits another big milestone: 200,000 repositories on GitHub depend on it for their tests and development. Thank you for choosing tools made with care ❤️

May I have 1 minute of your time?
You will not regret it. This is THE testing video I want you all to see. Might be hands-down the best video I've ever recorded.

Huge news to Storybook developers using MSW: version 3.0 of our add-on has just been released! 🎉
github.com/mswjs/msw-storybo…
This brings a new architecture to support both CSF3 and CSF4, fix some long-standing issues, become dependency-free, and a ton more.
Please help us make v3.0 better: vote on this.
If you're using MSW (@ApiMocking) in @reactnative, would you prefer "msw/native" to automatically include all the necessary polyfills for it to run? (e.g. URL, streams, etc).
