A simple server to share objects on an s3 bucket and display them in a nice way.

Features

• Share any object on an s3 bucket
• Generate short urls for the share
• Simple API to create shares

Building

Run make and the binary together with the web frontend will be in the build directory.

Usage

Run the s3browser binary with the --help flag to see the available options. The public directory needs to be in the same directory as the binary.

S3Share requires two things:

• a s3 bucket with read access
• a sql database

Docker

The docker image is available at Dockerhub. There is also a docker-compose file that can be used as an example.

API

Use the provided username and password with basic auth.

Shares ids consist of six alphanumeric characters e.g. jW8ADy.

• GET /api/share: Get a list of all shares
• GET /api/share/:id: Get a share by id. Result:

{"slug":"jW8ADy","key":"/myObj.txt"}

• POST /api/share: Create a new share. Data to send:

{"key":"/myObj.txt"}

• DELETE /api/share/:id: Delete a share

Other urls are:

• /:id to get the default site to display the share.
• /s/:id to get the shared file directly.

When you request a shared file directly, you can add anything after a dot behind the id e.g. /s/jW8ADy.png. This is done to make the browser display the file correctly. On the server side, this will be stripped away.
