NodeJS versions

support >=4.0.0

Usage

Base example with promises.

const connector = require('asterisk-ami-connector')({reconnect: true});

connector.connect('login', 'password', {host: '127.0.0.1', port: 5038})
    .then(amiConnection => {
        amiConnection
            .on('event', event  => {
                console.log(event);
                amiConnection.close();
            })
            .on('response', response  => console.log(response))
            .on('close', ()  => console.log('closed'))
            .on('error', error  => console.log(error));
    })
    .catch(error => console.log(error));

or using co for synchronous code style

const connector = require('asterisk-ami-connector')({reconnect: true});
const co = require('co');

co(function*(){
    let amiConnection = yield connector.connect('login', 'password', {host: '127.0.0.1', port: 5038});
    
    amiConnection
        .on('event', event  => {
            console.log(event);
            amiConnection.close();
        })
        .on('response', response  => console.log(response))
        .on('close', ()  => console.log('closed'))
        .on('error', error  => console.log(error));
})
    .catch(error => console.log(error));

or with co like synchronous style

Some details about module functionality

Options of connection setup to Asterisk AMI:

• reconnect - default is false. Reconnection during connection setup.
• maxAttemptsCount - default is null (infinity). Max count of attempts of reconnection.
• attemptsDelay - default is 1000 (ms). Time delay between attempts of reconnection.

Method connect

It takes the following parameters:

• login - Asterisks AMI login;
• secret - Asterisks AMI password;
• options - standard options for net.connect method.

It always returns promise. That promise will be resolved with instance of AmiConnection, or will be reject with AmiAuthError.

Class AmiConnection

Available props:

• .isConnected - true when connection to Asterisk AMI established;
• .lastEvent - last event by Asterisk;
• .lastResponse - last response by Asterisk;
• .lastWroteData - last wrote data to Asterisk's AMI socket (from client's code);

Available events:

• event - it fires when AMI event was received. Handler receives AMI event object.
• response - it fires when AMI response was received. Handler receives AMI response object.
• close - it fires when AMI connection was closed.
• error - it fires when error occurred. Handler receives error.
• data - it fires when data was received from AMI socket. Handler receives buffer of received data.

Class AmiAuthError
