Cothority client library in Javascript
This library offers methods to talk to a cothority node. At this point, it offers a socket interface that marshals and unmarshals automatically protobuf messages.

const net = cothority.net; // the network module
const serverAddress = "ws://127.0.0.1:8000";
const socket = new net.Socket(serverAddress); // socket to talk to a conode
// the data that we want to send, as a JS object
const deviceMessage = {
point: new Uint8Array([1,2,3,4]);
}
// the name of the protobuf structure we are sending
const sendingMessageName = "Device";
// the name of the protobuf structure we expect to receive
const expectedMessageName = "ID";
socket.send(sendingMessageName, expectedMessageName, deviceMessage)
.then((data) => {
// data is a JS object
console.log(data.id);
}).catch((err) => {
console.log("error: " + err);

Development
You need to have npm installed. Then
git clone https://github.com/dedis/cothority"
cd cothority/external/js/cothority
npm installYou should be able to run the tests with
npm run testProtobuf generation
To add a new protobuf file to the library, simply place your *.proto file
somewhere in lib/protobuf/build/models and then run
npm run protobufThat would compile all protobuf definitions into a single JSON file
(models.json). This json file is then embedded in the library automatically.
