Easy and fast file sharing from the command-line. This code contains the server with everything you need to create your own instance.

Transfer.sh currently supports the s3 (Amazon S3), gdrive (Google Drive) providers, and local file system (local).

## Disclaimer
This project repository has no relation with the service at https://transfer.sh that's managed by https://storj.io.
So far we cannot address any issue related to the service at https://transfer.sh.

If you want to use TLS using your own certificates, set tls-listener to :443, force-https, tls-cert-file and tls-private-key.

## Development

Switched to GO111MODULE

```bash
go run main.go --provider=local --listener :8080 --temp-path=/tmp/ --basedir=/tmp/
```

## Build

If on go < 1.11
```bash
go get -u -v ./...
```

```bash
go build -o transfersh main.go
```

## Docker

For easy deployment, we've created a Docker container.

```bash
docker run --publish 8080:8080 dutchcoders/transfer.sh:latest --provider local --basedir /tmp/
```

## S3 Usage

For the usage with a AWS S3 Bucket, you just need to specify the following options:
- provider
- aws-access-key
- aws-secret-key
- bucket
- s3-region

If you specify the s3-region, you don't need to set the endpoint URL since the correct endpoint will used automatically.

### Custom S3 providers

To use a custom non-AWS S3 provider, you need to specify the endpoint as defined from your cloud provider.

## Storj Network Provider

To use the Storj Network as storage provider you need to specify the following flags:
- provider `--provider storj`
- storj-access _(either via flag or environment variable STORJ_ACCESS)_
- storj-bucket _(either via flag or environment variable STORJ_BUCKET)_

### Creating Bucket and Scope

In preparation you need to create a scope (or copy it from the uplink configuration) and a bucket.

To get started, download the latest uplink from the release page: https://github.com/storj/storj/releases

After extracting, execute `uplink setup`. The Wizard asks for Satellite to use, the API Key 
(which you can retrieve via the Satellite UI), as well as an Encryption Key.
Once the uplink is setup create the bucket using the following schema: 
`uplink mb sj://<BUCKET>` where <BUCKET> is your desired name.

Afterwards you can copy the SCOPE out of the configuration file of the uplink and then start the startup of the
transfer.sh endpoint. For enhanced security its recommended to provide both the scope and the bucket name as ENV Variables.

Example:
```
export STORJ_BUCKET=transfersh
export STORJ_ACCESS=<SCOPE>
transfer.sh --provider storj
```

## Google Drive Usage

For the usage with Google drive, you need to specify the following options:
- provider
- gdrive-client-json-filepath
- gdrive-local-config-path
- basedir

### Creating Gdrive Client Json

You need to create a Oauth Client id from console.cloud.google.com
download the file and place into a safe directory

### Usage example

```go run main.go --provider gdrive --basedir /tmp/ --gdrive-client-json-filepath /[credential_dir] --gdrive-local-config-path [directory_to_save_config] ```
