How to add metadata to a request in custom middleware?

[danthegoodman1]

I have middleware that validates an API key, and checks to make sure that key has the correct permission. I'd like to attach this API key struct to the request so I can pass on some of its properties to the route handlers. Is there an elegant way to do this in Echo? My current solution is to encode my API Key data back into the header (replacing the key) and letting it continue.

Ah it seems Custom Context is the way to go: https://echo.labstack.com/guide/context/
