Simple, lightweight and expressive web scraping with Node.js
const scrapy = require('node-scrapy')
const fetch = require('node-fetch')
const url = 'https://github.com/expressjs/express'
const model = '.mb-3.h4 + .f4.mt-3'
fetch(url)
.then((res) => res.text())
.then((body) => {
console.log(scrapy.extract(body, model))
})
.catch(console.error)
// Fast, unopinionated, minimalist web framework for node.
node-scrapy can resolve complex objects. Give it a data model:
const fetch = require('node-fetch')
const url = 'https://github.com/strongloop/express'
const model = {
author: '.author ($ | trim)',
repo: '[itemprop="name"] ($ | trim)',
stats: {
commits: '.js-details-container > div:last-child strong',
branches: '.octicon-git-branch + strong',
releases: 'a[href$="/releases"] > span',
contributors: 'a[href$="/graphs/contributors"] > span',
social: {
watch: '.pagehead-actions > li:nth-child(1) .social-count ($ | trim)',
stars: '.pagehead-actions > li:nth-child(2) .social-count ($ | trim)',
forks: '.pagehead-actions > li:nth-child(3) .social-count ($ | trim)',
},
},
files: [
'.js-active-navigation-container .Box-row > :nth-child(2)',
{
name: 'a',
url: 'a (href)',
},
],
}
fetch(url)
.then((res) => res.text())
.then((body) => {
console.log(scrapy.extract(body, model))
})
.catch(console.error)
...and Scrapy will return:
