Adding timeout and multiple abort signals to fetch() (TypeScript/React)

1

Vercel

In my latest project, I made a Node/Express API backend which acted as a proxy between multiple public APIs and my frontend. After deploying it to Vercel, I encountered this error: The Serverless Function has timed out. This happens when one of the upstream APIs takes too long to respond but could also happen with slow database connections. Vercel has a guide on this error that explains why it happens and that your backend should return a response to the client if the upstream service takes too long and not wait forever for the response.

npm

Finally, I've published the fetchMS() and multiSignal() as packages on NPM so you can install and use them easily. Check the package readme for more information:.
