⚡ params field missing from Context type

[eratio08]

The params field seems to be missing from the Context type.
See https://doc.deno.land/https/deno.land/x/oak/mod.ts#Context

Currently working around this by:

router.get("/:name",  (
    ctx: oak.Context & {params: { name: string } }
) => {...});

@eratio08 params exists only on the RouterContext, which is what is passed to router middleware. The type is inferred be default, so there should be no need to type the ctx. The following works fine:

router.get("/:name", (ctx) => {
  ctx.params; // no error
});

If you want to strongly type the context, there is a generic you can supply:

router.get<{ name: string }>((ctx) => {
  ctx.router.name;  // again, no error
});

If for some reason you want to be explicit about the type on a router context, use RouterContext instead of Context as it is also exported from the mod.ts.

Just curious, Why would we restrict anybody to be able to use params object in any other subsequent function outside router? @kitsonk

😕 The params directly relate to the route that was parsed. Subsequent functions outside of the router wouldn't be for that route.

Pardon me, I misread the RouterContext.
