Install

$ npm install tfs

Usage

var tfs = require('tfs');

// var client = tfs.createClient({
//   rootServer: '$host:port',
//   appkey: '$your_appkey',
//   imageServers: ['$your_server1', '$your_server2']
// });

// e.g.: test environment on tb daily
var client = tfs.createClient({
  rootServer: '$tfsdomain:$port',
  appkey: 'appkey',
  imageServers: [
    'img01.tfs.com',
    'img02.tfs.com'
  ]
});

// upload normal file
client.upload(filepath, function (err, info) {
  console.log(info);
  // {
  //   name: 'T2xRETBgZv1RCvBVdK.jpg',
  //   url: 'http://img1.tfs.com/tfscom/T2xRETBgZv1RCvBVdK.jpg',
  //   size: 1024
  // }
});

// upload file content buffer directly
client.upload(fs.readFileSync(filepath), '', function (err, info) {
  console.log(info);
  // {
  //   name: 'T1Pj9zXkRYXXXXXXXX',
  //   url: 'http://img1.tfs.com/tfscom/T1Pj9zXkRYXXXXXXXX',
  //   size: 5929
  // }
});

// upload a stream
client.upload(fs.createReadStream(filepath), 'jpg', function (err, info) {
  console.log(info);
  // {
  //   name: 'T2xRETBgZv1RCvBVdL.jpg',
  //   url: 'http://img1.tfs.com/tfscom/T2xRETBgZv1RCvBVdL.jpg',
  //   size: 1024
  // }
});

// upload custom name file
// use uploadPrivateFile to upload a privateFile. if to do so, note the filename before ".jpg" will be suffix a ".tfsprivate"
// if no imageServer be specified, the url might unusable.
client.uploadFile(filepath, '320', 'foo.jpg', function (err, info) {
  console.log(info);
  // {
  //   name: 'L1/1/320/foo.jpg',
  //   url: 'http://img1.tfs.com/L1/1/320/foo.jpg',
  //   size: 1984
  // }
});

// upload private file, will not get by CDN
client.uploadPrivate(filepath, function (err, info) {
  console.log(info);
  // {
  //   name: 'T1XeRfXkBXXXXXXXXX.tfsprivate.jpg',
  //   size: 11779,
  //   url: 'http://img01.daily.taobaocdn.net/tfscom/T1XeRfXkBXXXXXXXXX.tfsprivate.jpg'
  // }
});
