Technology Used

  • Node.js
  • MongoDB A NoSQL Database that uses JSON-like data with schemata.
  • Mongoose A MongoDB object modeling tool designed to work in an asynchronous environment.
  • Express package Fast, unopinionated, minimalist web framework.
  • Express Handlebars Node module as the view engine for Express
  • Axios Promise based HTTP client for the browser and node.js
  • Cheerio Parses markup and provides an API for traversing/manipulating the resulting data structure.
  • body-parser Parse incoming request bodies in a middleware before your handlers, available under the req.body property.


  1. In the Nav Bar there will a Home, Saved Articles, and Scrape New Articles.

  2. When Home Page is loaded, the articles list will either be empty or shows the last scraped Articles from Articles Collection in the MongoDB database.

  3. To scrape articles, press the 'Scrape New Articles' button. News Scraper Screenshot

  4. At the end of each article there is a single button showing 'Save Article' or 'Saved' if it has been saved already. Clicking on 'Save Article' will save selected article into the Saved Articles collection in MongoDB. News Scraper Screenshot

MongoDB CRUD Functions


When scraping for new articles, the algorithm skips saving the article if there already exists an article with the same title.

Deleting and Dropping

  • delete an entry with db.[COLLECTION_NAME].remove()
  • Empty a collection with db.[COLLECTION_NAME].remove({}, callback)
  • Drop a collection with db.[COLLECTION_NAME].drop()
  • Drop a Database with db.dropDatabase()


  • '/' should pull data from MongoDB. If Empty it will scrape new articles
  • '/api/scrape' route will clear the MongoDB collection and pull new articles.

Programmer's Notes

  • Use .filter() to filter atabase.
    • const fiteredCatalog = catalog.filter( item => !item.saved) returns items.saved=false
  • ES6 Fat Arrow Function does not work with $(document).on("click", ".item", ()=> {...})
  • Problems with articles not loading after location.reload().
  • Anatomy of an HTTP Transaction in Node.js
const http = require('http');

const server = http.createServer((request, response) => {
  // magic happens here!
* We are NOT using `http` but **`Express`** to handle our http transactions and routing.
  • Express refresher:
    • Robust routing
    • Focus on high performance
    • Super-high test coverage
    • HTTP helpers (redirection, caching, etc)
    • View system supporting 14+ template engines
    • Content negotiation
    • Executable for generating applications quickly
