tus-java-server Dropwizard Demo

Small Java web server demo based on Dropwizard that uses the tus-java-server library and the Uppy file uploader to support the tus file upload protocol. This allows you to support resumable and asynchronous file uploads in a Dropwizard web application for very large files over slow and unreliable internet connections.

Build and run

To build and run this demo, execute the following commands:

$ git clone https://github.com/tomdesair/tus-java-server-dropwizard-demo.git
$ cd tus-java-server-dropwizard-demo
$ mvn clean package
$ java -jar target/dropwizard-tus-demo-0.0.1-SNAPSHOT.jar server

Then visit http://localhost:8080/ in your browser and try to upload a file using the Uppy file uploader.

CLI Commands

This Dropwizard demo also supports the following CLI commands:

• java -jar target/dropwizard-tus-demo-0.0.1-SNAPSHOT.jar clean-uploads: Clean up any expired uploads from the storage backend.
• java -jar target/dropwizard-tus-demo-0.0.1-SNAPSHOT.jar upload -f "path-to-file": Upload the specified file to the server using the tus-java-client library. This command is mainly for testing purposes.

Most Important Classes

To help you in understanding this code, this are the most important classes and files:

• TusUploadResource: This class makes the /api/upload endpoint available and passes all requests to the TusFileUploadService from the tus-java-server library.
• TusFileUploadApplication: This class instantiates all endpoints and commands and builds the TusFileUploadService based on the given configuration.
• assets\js\uppy-fileupload.js: This file contains the configuration of the JavaScript tus client Uppy.
• IndexResource: This class will load the main form and processes the submitted information and uploaded files.
• TusEndpointHealthCheck: Dropwizard health check class that does a basic check to see if the tus upload endpoint is functioning properly.
• me.desair.dropwizard.cli: Package that contains the classes that implement the above mentioned CLI commands.
