I'm using koa-router.

How can I get the request's query string params?

This is the best I managed to write:

import koaRouter from 'koa-router';



const router = koaRouter({ prefix: '/courses' });



router.get('/', async (ctx) => {

        console.log(ctx.qs[lecturer]);

    });

but qs is undefined

Any help will be profoundly appreciated!
