app.use(async (ctx, next) => { await next() ctx.status = 200 // koa defaults to 404 when it sees that status is unset return new Promise((resolve, reject) => { ctx.res.on('close', resolve) ctx.res.on('finish', resolve) nuxt.render(ctx.req, ctx.res, promise => { // nuxt.render passes a rejected promise into callback on error. promise.then(resolve).catch(reject) }) }) })
