PowerJet#call() to call methods defined on a remote PowerJet.
Encryption support based on Node.js Cipher and Decipher.

Installation

yarn add socket-jet
# or
npm install socket-jet --save

Usage

Basic Jet

Server

let server = Net.createServer(socket => {
  let jet = new Jet(socket);

  jet.on('data', data => {
    console.log(data); // {thank: 'you'} from client.
  });

  jet.send('hello').then(
    () => console.log('"hello" sent'),
    error => console.error(error),
  );
});

server.listen(10047);

Client

let socket = Net.connect(10047, () => {
  let jet = new Jet(socket);

  jet.on('data', data => {
    console.log(data); // 'hello' from server.
  });

  jet.send({thank: 'you'}).then(
    () => console.log('data sent'),
    error => console.error(error),
  );
});

Power Jet

Server

class ServerPowerJet extends PowerJet {
  async test(timeout: number): Promise<string> {
    return await new Promise<string>(resolve => {
      setTimeout(resolve, timeout, 'hello, jet!');
    });
  }
}

let server = Net.createServer(socket => {
  new ServerPowerJet(socket);
});

server.listen(10047);

Client

let socket = Net.connect(10047, () => {
  // Note: Client can also have derived `PowerJet` with methods to be called by server.
  let jet = new PowerJet(socket);

  jet.call('test', 1000).then(console.log); // 'hello, jet!' after 1000ms.
});

Encrypted Jet

Server

let server = Net.createServer(socket => {
  let jet = new Jet(socket, {
    crypto: {
      algorithm: 'aes-256-cfb',
      password: 'some password',
    },
  });

  jet.on('data', data => {
    console.log(data); // {thank: 'you'} from client.
  });

  jet.send('hello').then(
    () => console.log('"hello" sent'),
    error => console.error(error),
  );
});

server.listen(10047);

Client

let socket = Net.connect(10047, () => {
  let jet = new Jet(socket, {
    crypto: {
      algorithm: 'aes-256-cfb',
      password: 'some password',
    },
  });

  jet.on('data', data => {
    console.log(data); // 'hello' from server.
  });

  jet.send({thank: 'you'}).then(
    () => console.log('data sent'),
    error => console.error(error),
  );
});
