**Cheerio js** is a Javascript technology used for web-scraping in server-side implementations. **Web-scraping** is a scripted method of extracting data from a website that can be tailored to your use-case. NodeJS is often used as the server-side platform. With node installed, you can begin using cheerio after doing an **npm** install using the command: 
```
npm install cheerio
```

> **Warning:** Be careful to only scrape websites that you have permission to scrape. Scraping text from certain websites may be a breach of the copywrite, a violation of privacy, and/or against the terms of service.



# Features of cheerio js
Cheerio js is built over fb55's [htmlparser2](https://github.com/fb55/htmlparser2/), which parses HTML pages and allows the user to traverse/manipulate the resulting data structure. The syntax of cheerio js is similar to jQuery and the implementation is efficient and robust. 

# Usage
You can specify (find) elements on a web page and analyze the information depending on your use case. With this information, you can do everything you could do with objects in a programming language including counting instances of a specific object, looping through the instances to extract useful information, and more. For instance, you may want to extract all the text in the `<h1>` (or headline) tags from a web-page.
