Scraper

This project is a basic tool to scrap a data from a website
|
|
using a CSS selector.
|
|
|
|
For example, if you want to retrieve the number of a project's releases hosted on github:
|
|
|
|
With CLI
|
|
---
|
|
|
|
```
|
|
node src/cli.js \
|
|
--url https://github.com/foo/bar \
|
|
--selector '.repository-content .numbers-summary li:nth-child(4) a' \
|
|
--tags \
|
|
--breaks \
|
|
--spaces \
|
|
--breaks \
|
|
--trim
|
|
```
|
|
|
|
...will show `XXX releases`.
|
|
|
|
More help with `node src/cli.js --help`.
|
|
|
|
With code
|
|
---------
|
|
|
|
```
|
|
const scraper = require('deblan-scraper')
|
|

const options = {

url: 'https://github.com/foo/bar',
|
|
acceptAllStatus: false, // Optional, default is `false`
|
|
method: 'GET', // Optional, default is `GET`
|
|
}
|
|
|
|
const isMultiple = false // get the first result, `true` to get an array of results
|
|
|
|
const selector = '.repository-content .numbers-summary li:nth-child(4) a'
|
|
|
|
const filters = {
|
|
tags: null, // Removes tags. You can specify the tags to remove (separated by comma)
|
|
breaks: null, // Removes breaks (\n, \r)
|
|
spaces: null, // Replaces 2 successive spaces by 1, except breaks
|
