1. TIL (Today I Learned)

Today I reviewed and tried to redo my codes I wrote in the past pair programming session. It was about how to use fetch module in javascript. It was quite tricky but I learned a lot!

Using basic Chaining

var newsURL = 'http://localhost:5000/data/latestNews';
var weatherURL = 'http://localhost:5000/data/weather';

function getNewsAndWeather() {
  const result = {};
  return fetch(newsURL)
  .then((newsData) => newsData.json())
  .then((newsJson) => {
    result.news = newsJson.data
    return fetch(weatherURL)
  })
  .then((weatherData) => weatherData.json())
  .then((weatherJson) => {
    result.weather = weatherJson
    return result;
  })
  // TODO: fetch을 이용해 작성합니다
  // TODO: 여러개의 Promise를 then으로 연결하여 작성합니다
}

if (typeof window === 'undefined') {
  module.exports = {
    getNewsAndWeather
  }
}

Using Promise.all()

var newsURL = 'http://localhost:5000/data/latestNews';
var weatherURL = 'http://localhost:5000/data/weather';

function getNewsAndWeatherAll() {
  return Promise.all([fetch(newsURL), fetch(weatherURL)])
  .then(([news, weather]) => Promise.all([news.json(), weather.json()]))
  .then(([news, weather]) => ({news: news.data, weather}))
}

//   return Promise.all([fetch(newsURL), fetch(weatherURL)])
//  .then(([news, weather]) => Promise.all([news.json(), weather.json()]))
//  .then(([news, weather]) => ({news: news.data, weather}))
if (typeof window === 'undefined') {
  module.exports = {
    getNewsAndWeatherAll
  }
}

Using asyncAwait

var newsURL = 'http://localhost:5000/data/latestNews';
var weatherURL = 'http://localhost:5000/data/weather';

async function getNewsAndWeatherAsync() {
  const news = await fetch(newsURL).then((news) => news.json());
  const weather = await fetch(weatherURL).then((weather) => weather.json());
  return { news: news.data, weather: weather }
}

  // const news = await fetch(newsURL).then((data1) => data1.json());
  // const weather = await fetch(weatherURL).then((data2) => data2.json());
  // return { news: news.data, weather: weather };

if (typeof window === 'undefined') {
  module.exports = {
    getNewsAndWeatherAsync
  }
}

2. 3 Things to be Thankful For

1. Thankful for God reminding me how weak I am and arrogant I am.
2. Thankful for God allowing me to have a interview.
3. Thankful for God reminding me of His Love.

3. Ideas and Things to Think About

1. Don't try to invent the wheel, is a quote my teacher told me during the live session. I got inspired on reminding myself that the best way to start a bootcamp in Thailand is to use the data base codestates have and move it into Thailand and translate it. Don't try to reinvent the wheel!
