awos for node: https://github.com/shimohq/awos-js

Features

• enable shards bucket
• add retry strategy
• avoid 404 status code:
  • Get(objectName string) (string, error) will return "", nil when object not exist
  • Head(key string, meta []string) (map[string]string, error) will return nil, nil when object not exist

Installing

Use go get to retrieve the SDK to add it to your GOPATH workspace, or project's Go module dependencies.

    Bucket: "string"
    // Optional, choose which bucket to use based on the last character of the key,
