What is this?

• this is a Google Messages Client library to send message with a backend .eg. with express to send otp messages. This module uses your own number to work as a sms gateway api and you can send message to other person with your own number.

How to use

1. install the package from npm

npm install messages-web

2. Use it

• Without credentials

const { default: MessagesClient } = require('messages-web')
const fs = require('fs')

const client = new MessagesClient()

client.on('qr-code', (base64Image) => {
    // example code to save image
    fs.writeFileSync('qr.jpg', base64Image.replace(/^data:image\/png;base64,/, ""), { encoding: 'base64' })
    // your code
})

client.on('authenticated', async (service) => {
    const inbox = service.getInbox()
    const credentials = await client.getCredentials()
    fs.writeFileSync('credentials.json', JSON.stringify(credentials, null, '\t'))
    await client.quit()
})

• With credentials

const { default: MessagesClient } = require('messages-web')

const credentials = MessagesClient.loadCredentialFile('credentials.json')
const client = new MessagesClient({ credentials })

client.on('authenticated', async (service) => {
    const inbox = await service.getInbox()
    console.log('Inbox', inbox)
    await client.quit()
})

const { default: MessagesClient } = require('messages-web')

const credentials = MessagesClient.loadCredentialFile('credentials.json')
const client = new MessagesClient({ credentials })

client.on('authenticated', async (service) => {
    console.log('Sending message...')
    await service.sendMessage('+91987654321', 'Test message from SMS Client.') 
    console.log('Done!')
    await client.quit()
})
