• Visit the urql devtools exchange README for how to add the exchange to an Urql client

Notes

Shoutout to @kiraarghy for the suggestion

@andyrichardson quick note 😅 I suppose this is a change suggestion but there isn't enough details in here for someone to pick this up. It's ok if there's already someone (like yourself or someone else) that you'll assign to this, but given that it's tagged as "good first issue" it'll probably need more instructions, e.g. by following the RFC template.

Edit: Also feel free to add it to the RFC project board (probably immediately as "ready") if anyone can pick this up straight away 🙌
