Purge CloudFlare cache on deploy

cloudflare.json

{
  "email": "[email protected]",
  "zone": "CLOUDFLARE_ZONE",
  "token": "CLOUDFLARE_TOKEN"
}

gulpfile.js

var gulp = require('gulp')
var request = require('request')

gulp.task('purge-cache', function () {
  var cf = require('./cloudflare.json')

  request({
    url: 'https://api.cloudflare.com/client/v4/zones/' + cf.zone + '/purge_cache',
    method: 'DELETE',
    headers: {
      'X-AUTH-EMAIL': cf.email,
      'X-Auth-Key': cf.token,
      'Content-Type': 'application/json'
    },
    body: {
      purge_everything: true
    },
    json: true
  }, function (err, response, body) {
    if (err) {
      throw err
    }

    console.log('CloudFlare cache purge response')
    console.log(body)
  })
})

You can get zone id by listing zones https://api.cloudflare.com/#zone-list-zones and your api key from https://www.cloudflare.com/a/account/my-account

how about purging just one file @fouad?

@hadifarnoud - here's how. files can be just an array of URLs or it can be objects to purge selectively by origin etc. Both included here.

gulp.task('purge-cache', function () {
  let config = require(path.join(__dirname, 'config.json'));
  let cf = config.cloudflare;

  request({
    url: 'https://api.cloudflare.com/client/v4/zones/' + cf.zone + '/purge_cache',
    method: 'DELETE',
    headers: {
      'X-AUTH-EMAIL': cf.email,
      'X-Auth-Key': cf.token,
      'Content-Type': 'application/json'
    },
    body: {
      purge_everything: false
      files: [
        "http://www.example.com/css/styles.css",
        {
          "url": "http://www.example.com/cat_picture.jpg",
          "headers": {
            "Origin": "cloudflare.com",
            "CF-IPCountry": "US",
            "CF-Device-Type": "desktop"
          }
        }
      ]
    },
    json: true
  }, function (err, response, body) {
    if (err) { console.error("!!! Error purging Cloudflare cache"); return; }

    console.log('Cloudflare cache purge response: ');
    console.log(body);
  });
});

Nice, thanks for that! :)
Btw, I had to use the Global API instead of a new Token, didn't work otherwise not sure why.
