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](https://hub.docker.com/r/djeeberjr/s3share). There is also a [docker-compose](docker-compose.yml) 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:
```json
{"slug":"jW8ADy","key":"/myObj.txt"}
```
- `POST /api/share`: Create a new share. Data to send:
```json
{"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.
