## Mission
The tus mission is to make file uploading more reliable, faster and a better
2013-03-17 11:46:12 +00:00
user experience. Instead of building yet another black box service, we are
dedicated to providing an open solution to this problem.

## Roadmap
2013-03-17 11:06:53 +00:00
The initial goal for this project to come up with a good and simple solution
for resumable file uploads over http.
2013-03-16 21:23:25 +00:00
2013-03-16 23:49:13 +00:00
* Defining a good http API (in progress)
2013-03-16 23:39:08 +00:00
* Implementing a minimal / robust server for it
2013-03-16 21:25:33 +00:00
* Creating an HTML5 client
2013-03-16 21:23:25 +00:00
* Setting up an online demo
* Integrating Amazon S3 for storage
* Creating an iOS client
2013-03-17 11:06:53 +00:00
Future features will be based on [your
feedback](https://github.com/tus/tusd/issues/new). A few potential ideas:
* Alternative transfer mechanisms: FTP, UDP, E-Mail, etc.
* Security: Authentication Tokens, HTTPS, etc.
* Support for running tusd instances in a geographically distributed cluster
(reverse CDN)
* Alternative storage backends: Cloud Files, Dropbox, etc.
* More clients: Android, PhoneGap, etc.
2013-03-17 11:11:36 +00:00
* Service integrations: Zencoder, Encoding.com, Youtube, Vimeo, Facebook, etc.
* File meta data analysis
* Thumbnail generation
2013-03-17 11:06:53 +00:00
Once the project matures, we plan to offer a hosted service and support
2013-03-17 11:08:24 +00:00
contracts. However, all code will continue to be released as open source, and
you'll always be able to run your own deployments easily. There will be no bait
and switch.

## HTTP API
2013-03-17 09:41:17 +00:00
Below is the proposed HTTP API for resumable file uploading.
Prior art:
2013-03-17 09:40:12 +00:00
* [Google Drive - Upload Files](https://developers.google.com/drive/manage-uploads)
2013-03-17 10:29:08 +00:00
* [Resumable Media Uploads in the Google Data Protocol](https://developers.google.com/gdata/docs/resumable_upload) (deprecated)
* [ResumableHttpRequestsProposal from Gears](http://code.google.com/p/gears/wiki/ResumableHttpRequestsProposal) (deprecated)
2013-03-17 09:40:12 +00:00
2013-03-16 23:44:23 +00:00
### POST /files
2013-03-16 23:32:37 +00:00
2013-03-17 10:45:36 +00:00
Used to create a resumable file upload. You may send parts or all of your file
along with this request, but this is discouraged as you will not be able to
resume the request if something goes wrong.
**Request Example:**
2013-03-16 23:32:37 +00:00
```
POST /files HTTP/1.1
Host: tus.example.com
Content-Length: 0
Content-Range: bytes */100
2013-03-17 10:41:45 +00:00
Content-Type: image/jpg
2013-03-16 23:32:37 +00:00
```
2013-03-17 10:45:36 +00:00
```
<empty body>
```
2013-03-16 23:32:37 +00:00
2013-03-17 10:45:36 +00:00
**Response Example:**
2013-03-16 23:32:37 +00:00
```
HTTP/1.1 201 Created
Location: http://tus.example.com/files/123d3ebc995732b2
2013-03-17 10:41:45 +00:00
Content-Length: 0
2013-03-16 23:32:37 +00:00
```
2013-03-17 10:50:32 +00:00
The `Location` header returns the `<fileUrl>` to use for interacting with the
file upload.
### PUT \<fileUrl\>
2013-03-16 23:42:41 +00:00
2013-03-17 10:45:36 +00:00
**Request Example:**
2013-03-17 11:50:08 +00:00
2013-03-16 23:42:41 +00:00
```
PUT /files/123d3ebc995732b2 HTTP/1.1
Host: tus.example.com
Content-Length: 100
Content-Range: bytes 0-99/100
```
```
2013-03-17 10:45:36 +00:00
<bytes 0-99>
2013-03-16 23:42:41 +00:00
```
2013-03-17 10:45:36 +00:00
**Response Example:**
2013-03-16 23:42:41 +00:00
```
HTTP/1.1 200 Ok
```
2013-03-17 10:50:32 +00:00
### HEAD \<fileUrl\>
2013-03-17 10:41:45 +00:00
2013-03-17 11:50:08 +00:00
**Request Example:**
```
HEAD /files/123d3ebc995732b2 HTTP/1.1
Host: tus.example.com
```
**Response Example:**
```
HTTP/1.1 200 Ok
Content-Length: 100
Content-Type: image/jpg
X-Resume: bytes=20-50,60-99
```
The `X-Resume` header holds a [byte
range](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35.1) that
informs the client which parts of the file have not been received yet. It is
up to the client to choose appropiate `PUT` requests to complete the upload.
The absence of a `X-Resume` header means that the the entire file has been
received by the server.
2013-03-17 10:50:32 +00:00
### GET \<fileUrl\>
2013-03-17 10:41:45 +00:00
Used to download an uploaded file.

**Request:**
2013-03-17 10:41:45 +00:00
2013-03-16 23:32:37 +00:00

GET /files/123d3ebc995732b2 HTTP/1.1
2013-03-16 23:32:37 +00:00

```
2013-03-17 10:41:45 +00:00
