Prefix not work when pass router to another router using r.route

I pass router to router using r.use and prefix work fine. But when I try to pass using r.route prefix not work, I think it is because router delegate work to @koa/router.

Can you handler this problem that I can you r.route with prefix and add documentation: “Passing through routers and be able use prefix”

@Roman-Kirnos, you can create a util or helper file then add this fucntion to it.

// helper/util file
function routesWrap (router, PREFIX) {
  return router.routes.map(route => ({ 
    ...route,
    path: (PREFIX + route.path).slice(0, -1) 
  }))
}

Now, it’s shorter.

const Router = require('koa-joi-router');

const events = Router();
events.prefix(EVENTS_PREFIX_ROUTE);
events.get('/', { validate: validator.getAll }, events.getAll);

const apiV1 = Router();
apiV1.prefix('/api/v1');
apiV1.route(routesWrap(events, EVENTS_PREFIX_ROUTE)); // WORK

module.exports = apiV1;

You can use the Prefix path as constant like this;

const EVENTS_PREFIX_ROUTE = '/events'

Then use it like that and every thing work fine.

const Router = require('koa-joi-router');

const events = Router();
events.prefix(EVENTS_PREFIX_ROUTE);
events.get('/', { validate: validator.getAll }, events.getAll);

const apiV1 = Router();
apiV1.prefix('/api/v1');
apiV1.route(events.routes.map(route => ({ ...route, path: (EVENTS_PREFIX_ROUTE + route.path).slice(0, -1) }))); // WORK

module.exports = apiV1;
