How to use / permanent changes:

Install via npm i github:pedroslopez/whatsapp-web.js#multidevice

1. Heroku is no longer supported. Basically they follow a ephemeral file system, and it resets each time the app restarts and we rely on constantly updated data to keep messages, chats, even the session itself. Unless you have a DB that you can update at MILLESECOND intervals, I am pretty positive that Heroku hosting is done for.
2. As said above, the session now uses the filesystem, so for code this is what you have to do, take this example:

const SESSION_FILE_PATH = './session.json';
let sessionCfg;
if (fs.existsSync(SESSION_FILE_PATH)) {
    sessionCfg = require(SESSION_FILE_PATH);
}

const client = new Client({ puppeteer: { headless: false }, session: sessionCfg });
// You can use an existing session and avoid scanning a QR code by adding a "session" object to the client options.
// This object must include WABrowserId, WASecretBundle, WAToken1 and WAToken2.

// You also could connect to an existing instance of a browser
// { 
//    puppeteer: {
//        browserWSEndpoint: `ws://localhost:3000`
//    }
// }

client.initialize();

client.on('qr', (qr) => {
    // NOTE: This event will not be fired if a session is specified.
    console.log('QR RECEIVED', qr);
});

client.on('authenticated', (session) => {
    console.log('AUTHENTICATED', session);
    sessionCfg=session;
    fs.writeFile(SESSION_FILE_PATH, JSON.stringify(session), function (err) {
        if (err) {
            console.error(err);
        }
    });
});

client.on('auth_failure', msg => {
    // Fired if session restore was unsuccessfull
    console.error('AUTHENTICATION FAILURE', msg);
});

client.on('ready', () => {
    console.log('READY');
});

client.on('message', async msg => {
    console.log('MESSAGE RECEIVED', msg);
});

client.on('message_create', (msg) => {
    // Fired on all message creations, including your own
    if (msg.fromMe) {
        // do stuff here
    }
});

client.on('message_revoke_everyone', async (after, before) => {
    // Fired whenever a message is deleted by anyone (including you)
    console.log(after); // message after it was deleted.
    if (before) {
        console.log(before); // message before it was deleted.
    }
});

client.on('message_revoke_me', async (msg) => {
    // Fired whenever a message is only deleted in your own view.
    console.log(msg.body); // message before it was deleted.
});

client.on('message_ack', (msg, ack) => {
    /*
        == ACK VALUES ==
        ACK_ERROR: -1
        ACK_PENDING: 0
        ACK_SERVER: 1
        ACK_DEVICE: 2
        ACK_READ: 3
        ACK_PLAYED: 4
    */

    if(ack == 3) {
        // The message was read
    }
});

client.on('group_join', (notification) => {
    // User has joined or been added to the group.
    console.log('join', notification);
    notification.reply('User joined.');
});

client.on('group_leave', (notification) => {
    // User has left or been kicked from the group.
    console.log('leave', notification);
    notification.reply('User left.');
});

client.on('group_update', (notification) => {
    // Group picture, subject or description has been updated.
    console.log('update', notification);
});

client.on('change_battery', (batteryInfo) => {
    // Battery percentage for attached device has changed
    const { battery, plugged } = batteryInfo;
    console.log(`Battery: ${battery}% - Charging? ${plugged}`);
});

client.on('change_state', state => {
    console.log('CHANGE STATE', state );
});

client.on('disconnected', (reason) => {
    console.log('Client was logged out', reason);
});

becomes like this:

const client = new Client({ puppeteer: { headless: false }, clientId: 'example' });
client.initialize();

client.on('qr', (qr) => {
    // NOTE: This event will not be fired if a session is specified.
    console.log('QR RECEIVED', qr);
});

client.on('authenticated', () => {
    console.log('AUTHENTICATED');
});

client.on('auth_failure', msg => {
    // Fired if session restore was unsuccessfull
    console.error('AUTHENTICATION FAILURE', msg);
});

client.on('ready', () => {
    console.log('READY');
});

client.on('message', async msg => {
    console.log('MESSAGE RECEIVED', msg);
});

client.on('message_create', (msg) => {
    // Fired on all message creations, including your own
    if (msg.fromMe) {
        // do stuff here
    }
});

client.on('message_revoke_everyone', async (after, before) => {
    // Fired whenever a message is deleted by anyone (including you)
    console.log(after); // message after it was deleted.
    if (before) {
        console.log(before); // message before it was deleted.
    }
});

client.on('message_revoke_me', async (msg) => {
    // Fired whenever a message is only deleted in your own view.
    console.log(msg.body); // message before it was deleted.
});

client.on('message_ack', (msg, ack) => {
    /*
        == ACK VALUES ==
        ACK_ERROR: -1
        ACK_PENDING: 0
        ACK_SERVER: 1
        ACK_DEVICE: 2
        ACK_READ: 3
        ACK_PLAYED: 4
    */

    if(ack == 3) {
        // The message was read
    }
});

client.on('group_join', (notification) => {
    // User has joined or been added to the group.
    console.log('join', notification);
    notification.reply('User joined.');
});

client.on('group_leave', (notification) => {
    // User has left or been kicked from the group.
    console.log('leave', notification);
    notification.reply('User left.');
});

client.on('group_update', (notification) => {
    // Group picture, subject or description has been updated.
    console.log('update', notification);
});

client.on('change_state', state => {
    console.log('CHANGE STATE', state );
});

client.on('disconnected', (reason) => {
    console.log('Client was logged out', reason);
});

Meaning, there is no longer a session JSON that is given on auth nor is there change battery info. (also no longer phone info (ClientInfo.phone))

3. For now, Remote Browser / Browserless is not supported.

I tested it here and it worked perfectly.

@crboschi74

I believe that the error reported does not occur in the library, on the line: "whatsapp-web.js\src\Client.js:167:14" the event "Events.AUTHENTICATED" is launched and that calls something that was written by you in

"C:\newtec\waw\wanx.js:32:8"
Looks to me like you're passing a variable of the wrong type, check your code.

@crboschi74

Now you no longer need to enter the "session" parameter, the session data is saved in the folder informed in the "dataPath" attribute, if this attribute is omitted it will create a "WWebJS" folder in the project root saving the puppeteer session data.

You can also enter a "clienteId" parameter to separate it into several distinct sessions.

whatsapp-web.js/src/Client.js

Line 28 in 5b923cc

* @param {string} options.dataPath - Change the default path for saving session files, default is: "./WWebJS/"

You can't save the session, if you have more than one session you can pass in the clientId option to differentiate sessions.

Hi! Thanks for all your work.

I'm getting this issue

(WhatsApp works with Google Chrome 60+)

I already updated Puppeteer to the last version (10.4) but the issue continues
