RxJSの練習、キモすぎる。

rx-practice.js

const axios = require('axios');
const Rx = require('rxjs');
const { mergeMap, mapTo } = require('rxjs/operators');

const getArticles = () => (
  axios.get('https://qiita.com/api/v2/users/uutarou10/items')
    .then(res => {
      return res.data
    })
);

console.log('start');

Rx.timer(1000)
  .pipe(
    mergeMap(() => getArticles()),
    mergeMap(articles => {
      return articles.map(a => a);
    })
  )
  .subscribe(val => console.log(val.title));
