A simple node.js script to crawl and download information and images from pokeapi and pokemondb.net

pokemon_scraper_crawler.js

// Nodejs > 7 or some babel is required cause we use ES7 syntax here (arrow functions and async await)
// This script requires node-fetch and image-downloader packages in order to work
// get it in npm:
// npm install --save image-downloader node-fetch
const download = require('image-downloader')
const fetch = require('node-fetch')
// We are doing a for loop to get info for the first 152 pokemons
for (var i = 1; i < 153; i++){
  const asyncDownload = async () => {
  try {
    // download JSON information needed to crawl pokemondb
    let json = await (await fetch('https://pokeapi.co/api/v2/pokemon/'+i+'/')).json()
    console.log(json.name);
    // download the pokemon images
    let result = await download.image({url: 'https://img.pokemondb.net/artwork/'+json.name+'.jpg', dest: __dirname+'/pokemons'})
    console.log('File saved to', result)
  } 
  catch (error) {
      console.log('request failed', error)
    }
  }
  asyncDownload()
