Does MSW work with fetch server-side?

[thany]

I couldn't get it to work, I had to migrate Node.js native fetch over to axios which feels like a waste.

What are the steps to be able to use fetch during server-side execution please?

Hi!

MSW works with both native fetch and third-party libraries like Axios in Node.js. Was there a particular issue you experience that forced you to migrate? Share it below, chances are I've seen it before and can help you.

This is also a nice time to encourage you to migrate to msw@next that utilizes the Fetch API primitive as first class citizens in both browser and Node.js. Read more about it in #1464.

Well yeah, we used fetch (on the server, still) to do API requests to a remote server. Those requests were just passing through. The only thing we changed, is to use axios to make the very same requests, and they would be caught by MSW perfectly fine, exactly as intended.

Unfortunately, we had to move on and go with axios. And I don't see our project migrating back to fetch anytime soon, partly because we ran into this.

But if you're saying it ought to work, then I'm sure we just ran into a 100% reproducible bug for every request that only surfaced when using fetch. And since we already moved on, there's no way to dive into it anymore 😔

Got it. If you ever catch that bug again, please make sure to submit it. Thanks!
