An example to demonstrate chunked file uploading to a Java server. The client uses Resumable.js, which in turn uses HTML 5 file API to generate the chunks.

A .NET Core version is also available: https://github.com/edsoncunha/chunked-file-upload-csharp.

Requirements:

• Node.js

To install dependencies and run:

cd client
npm install
node app.js

Then browse to localhost:3000.

To install and run:

cd server
./mvnw package jetty:run

Then browse to localhost:8002.

...

Or simply cross your fingers and run both at once with:

./run_all.sh

Generate large files

dd if=/dev/urandom of=file.tmp bs=1M count=1024 #creates a 1GB file

Calculate SHA1

sha1sum file.tmp

Upload file.tmp, download it from server and check whether the checksums match

This sample takes Resumable.js and Swagger code samples as a frame of reference.
