Events

The following events are emitted.

start(callback)

Fired when restoring starts.

.on("start", function() {
    console.log("[STARTED USING]:", this.settings);
})

restoring - (asset)

When a file begins restoring.

.on("restoring", function(asset) {
   console.log("[RESTORING]", asset.original_url);
})

restored - (asset)

Fired when a file has been downloaded.

.on("restored", function(asset) {
   console.log("[RESTORED]", asset.original_url);
})

cdxquery

.on("cdxquery", function(cdx) {
  console.log("Snapshots Found: ", cdx.size);
})

completed - (results)

When the restore process has completed.

.on("completed", function(results) {
    console.log("restoration has completed");
    console.log("url: ", results.url);
    console.log("domain: ", results.domain);
    console.log("timestamp: ", results.timestamp);
    console.log("directory: ", results.directory);
    //console.log("first file: ", results.first_file);
    //console.log("started: ", results.started);
    //console.log("ended: ", results.ended);
    console.log("restored: ", results.restored_count);
    console.log("failed: ", results.failed_count);
    console.log("Runtime:", results.runtime_hms);

Can also be 20150801

limit - integer (default: 0)

limit number of files to download.

0 = no limit.

exact_url - boolean (default: false)

Downloads only the url provided not full site.

list - boolean (default: false)

Doesn't download any files.

concurrency - integer (default: 1)

Number of files to download at the same time.

only - string|RegEx (defalt: '')

directory - string (defalt: '.')

Methods

See Wayback.restore methods.

Wayback.snapshot(options, callback)

Use this to explore snapshots on web.archive.org by querying their CDX server. You can use this to build your own downloader.

Returns a Promise with an array of Assets found.

callback (optional) - function(asset)

This is an optional method that will be executed for each snapshot found in the snapshot search. The parameter received in the callback is an Asset.

Example:

Wayback.snapshot(
  {
    url: 'example.com',
    filter: 'statuscode:200',
    collapse: 'digest',
    matchType: 'exact',
    limit: 10,
    from: '20210623',
    to: '20210624'

  (asset) => {
    console.log('Snapshot', asset);
  }
);

Wayback.Asset (object)

An Asset is an object that gets downloaded or restured and is returned by various events.

Asset.properties

// CDX urlkey this.key = null;

// the url to restore this.original_url = "";

// path to local file this.restored_file = "";

this.timestamp = "";

// restored | failed | unarchived this.status = RESTORE_STATUS.EMPTY;

// mimetype: html, image, css, js, based on wayback types this.mimetype = "";

Asset.methods

Asset.getSnapShot(flag)

Set to true to fetch file in its original state, without any processing by the Wayback Machine or waybackpack. You will likely want this to always be true.

Wayback.createAsset(obj)

Helper method to create an Asset object.

obj maps to Asset.properties

Wayback.downloadAsset(Asset, directory)

This method will download an Asset to the directory provided.

Asset is an Asset object.

directory is the directory to write the asset content to.

Examples

var restore = Wayback.restore({
    url:
        "http://web.archive.org/web/20150531/http://example.com"
});

var restore = Wayback.restore({
    domain: 'example.com',
    timestamp: "20150531"
});

var restore = Wayback.restore('http://web.archive.org/web/20150531/http://example.com');

Wayback.downloader({
  url: 'https://trufish.org/',
  from: '20181001',
  to: '20201031',
  list: true,
  concurrency: 10,
  exact_url: false,
  exclude: /.(gif|jpg|jpeg|png|svg)$/i
})
  .on('completed', function (results) {
    console.log('completed');
    console.log(results);
  })
  .start((asset) => {
    console.log('Asset', asset.getSnapshotUrl());
  });

Wayback.snapshot({
  url: 'example.com',
  filter: 'statuscode:200',
  collapse: 'digest',
  matchType: 'exact',
  limit: 10,
  from: '20210623',
  to: '20210624'
})
  .then(([snapshots, url]) => {
    console.log('snapshots', snapshots);
    console.log('# snapshots found: ', snapshots.length);
    console.log('CDX Query URL:', url);
  })
  .catch((error) => {
    console.log('error', error);
  });
