Repository files navigation

A simple routing wrapper aroundpath-match.Similar tokoa-route, except it optionally handles methods better.All of these routers usepath-to-regexpunderneath, which is what Express uses as well.

constroute=require('koa-path-match')({/* options passed to path-to-regexp */})app.use(route('/:id',(ctx,next)=>{constid=ctx.params.id// do stuffswitch(ctx.request.method){}}))

Or you can create middleware per method:

app.use(route('/:id').get(asyncctx=>{ctx.body=awaitThings.getById(ctx.params.id)}).delete(asyncctx=>{awaitThings.delete(ctx.params.id)ctx.status=204}))

paths are just like Express routes.fns is either a single middlewareor nested arrays of middleware, just like Express.

When you don't setfns in theroute() function, a router instance is returned.

Define a middleware just for a specific method.

app.use(route('/:id').get(asyncctx=>{ctx.body=awaitThings.getById(ctx.params.id)}))

• next is not passed as a parameter.I consider this an anti-pattern in Koa - one route/method, one function.

Any keys defined in the path will be set toctx.params,overwriting any already existing keys defined.
