find-reachable-urls

find-reachable-urls

Passes back all URLs which respond with status code 200.

Installation

npm install find-reachable-urls --save

Usage

const findReachableUrls = require('find-reachable-urls')
const urls = [
  'https://google.com', // 200
  'https://github.com/nonexistent-url', // 404
  'https://github.com/OctoLinker/chrome-extension', // 301
]

findReachableUrls(urls)
  .then(function(reachableUrls) {
    console.log(reachableUrls)
    // ['https://google.com', 'https://github.com/OctoLinker/chrome-extension']
  })
  .catch(function(err) {
    // handle error
  })

Node-style callbacks are supported too:

findReachableUrls(urls, function(err, reachableUrls) { /*...*/ })

If you just need to look up one URL, pass it as an argument instead of an array:

findReachableUrls('http://mysite.com').then(...)

Tests

npm install
npm test
