libamf

An Action Message Format library for node.js.

Usage

Parser/Serializer

const libamf = require('libamf');

const data = libamf.serialize(5, libamf.ENCODING.AMF3);
const int = libamf.deserialize(data, libamf.ENCODING.AMF3);

Server

const {Server, Service} = require('libamf');

class PizzaService extends Service {
	constructor() {
		super('pizza');
		
		this.register('order', 'handleOrder');
		this.register('cancelOrder', this.cancelOrder.bind(this));
		this.register('asyncMethod', 'asyncMethod');
	}
	
	handleOrder(pizza, message) {
		message.respond({ status: 1, message: pizza.type + ' pizza ordered!'});
	}
	
	cancelOrder(pizza, message) {
		const id = pizza.id;
		
		return { status: 1, message: 'Order ' + id + ' has been cancelled successfully.'};
	}

	asyncMethod(message) {
		return new Promise((resolve, reject) => {
			resolve('this will be sent as a response');
		});
	}
}

const server = new Server();

// You can also just do this
server.on('data', packet => {
    console.log(packet);
});

server.registerService(pizzaService);
server.listen(8080, () => {
	console.log('Listening on port 8080');
});

You can stop services from enforcing the -service suffix to the name by doing:

libamf.Service.ForceSuffix = false;

You can also allow any service method to be used without registration by doing:

libamf.Service.RequireRegistration = false;

If you wish to return other values in your service methods, you can disable responding with return values using:

libamf.Service.ReturnResponses = false;

To write whole numbers as integers, use this:

libamf.AMF3.AssumeIntegers = true;

To disable the default homepage, use:

libamf.Server.DisableDefaultHome = true;

Client

const {Client} = require('libamf');
const client = new Client();

client.connect('http://localhost:8080/');
client.call('pizza-service.order', { type: 'cheese' }).then(res => {
	console.log(res);
});

SOL

const fs = require('fs');
const libamf = require('libamf');

fs.readFile('path/to/file.sol', (err, data) => {
	console.log(libamf.SOL.read(data));

	const newObj = new libamf.SOL.LSO({
        allow: false,
        always: false,
        allowsecure: false,
        alwayssecure: false,
        klimit: 100,
        hstsEnabled: false,
        hstsMaxAge: '0',
        hstsIncSubDomain: false,
        hstsStartTime: '0'
	});
	newObj.filename = 'domain/settings';
	newObj.version = 0;

	console.log(newObj.write());
});
