libamf-fix

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());
});
