koa2 - How to redirect some URL conditionally in the koa 2 -


this i'm thinking, pseudo code. 

const myredirect = (routepath) => {     newurl = routepath;     if (matches condition)         newurl = do_some_modification(routepath);            return next(newurl);  }  const myfunc = (routepath, myredirect) => (newurl, middleware) => {     return (ctx, newurl, next) => {         return middleware(ctx, newurl, next);     } };

how modify make work please ?

const route = async function(ctx, next){     if(shouldredirect){         ctx.redirect('/redirect-url') // redirect page     }     else{         ctx.somedata = getsomedata() // ctx.somedata available in next middleware         await next()  // go next middleware     } }
