Example of returning JSON in Node.js:

'use strict';

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

const moment = require('moment');

const app = new Koa();

const router = new Router();
router.all('/hello-koa', async (ctx) => {
  ctx.body = {
    errCode: 0,
    errorMessage: "",
    data: {
`msg: 'Hello视频',`
      // @see https://momentjs.com/docs/#/manipulating/utc-offset/
      now: moment().utcOffset(moment.duration(8, 'hours').asMinutes()).format('YYYY-MM-DD HH:mm:ss'),
    },
  }
});
app.use(router.routes());

app.listen(9000, () => {
  console.log(`Server start on http://localhost:9000`);
});
