Hi i'm trying to make a little modification to make serverSideRender work.

devMiddleware

exports.devMiddleware = async (ctx, next) => {
  ctx.locals = {};
  await expressMiddleware(ctx.req, {
    end: (content) => {
      ctx.body = content;
    },
    setHeader: (name, value) => {
      ctx.set(name, value);
    },
    locals: ctx.locals,
  }, next);
}

render layer

export default async (ctx, next) => {
  if (ctx.locals.webpackStats) {
    console.log(ctx.locals.webpackStats.toJson().assetsByChunkName);
  }
  await ctx.render('empty');
}

It renders a empty page if i'm turning serverSideRender to false. And when I'm turning serverSideRender to true, consoles out { index: [ 'bundle.js', 'bundle.js.map' ] } which is as expected, but in the browser it renders nothing(loading forever). Could someone tell me what's going on? I'm using koa2 with koa-views and ejs.

By the way did you have your problem solved? @rustam-gaifiev
