Extra methods

Usage

Use as a drop-in replacement of ali-oss:

import OSS from 'ali-oss-extra'
 
const store = new OSS({
  accessKeyId: 'your access key',
  accessKeySecret: 'your access secret',
  bucket: 'your bucket name',
  region: 'region of your bucket'
})

All methods from ali-oss are available. But every method returns a promise, which could be used in async/await:

// List top 10 buckets
const result = await store.listBuckets({ 'max-keys': 10 })

Return:

{ buckets:
   [ { name: 'my-bucket',
       region: 'oss-us-west-1',
       creationDate: '2016-05-29T12:13:03.000Z' },
     { name: 'my-data',
       region: 'oss-cn-shenzhen',
       creationDate: '2016-05-14T08:02:46.000Z' },
     { name: 'my-data-bj-dev',
       region: 'oss-cn-beijing',
       creationDate: '2016-05-24T15:17:53.000Z' },
     { name: 'my-data-dev2',
