facebook-message-api v1.0.4

Facebook Message API

This API is the only way to automate chat functionalities on a user account. We do this by emulating the browser. This means doing the exact same GET/POST requests and tricking Facebook into thinking we're accessing the website normally. Because we're doing it this way, this API won't work with an auth token but requires the credentials of a Facebook account.

Install

Install using npm:

npm install facebook-message-api

Install using yarn:

yarn add facebook-message-api

Testing your bots

If you want to test your bots without creating another account on Facebook, you can use Facebook Whitehat Accounts.

Authenticate

To authenticate your account you should create .env or export it on Environment variable Note: Please make sure that your .env is ignore on git to avoid stealing your credential or you can make your repo private.

# It can be username or email
EMAIL=markzuckerbot@facebook.com
PASSWORD=markzuckerbot

Example Usage

const command = require('facebook-message-api')

// Initialize the chat command first
// you may passed additional options, it can be accessed into command options from the callback
command.init({ prefix: '/' })

// You can add event middleware
// Note that this will be served as global event middleware
const eventMiddleware1 = (next) => {
  return async (event, api, options) => {
    // Handle before the event is resolved
    await next(event, api, options)
    // Or handle after event has been resolved
  }
}

const eventMiddleware2 = (next) => {
  return async (event, api, options) => {
    // Handle before the event is resolved
    await next(event, api, options)
    // Or handle after event has been resolved
  }
}

command.addEventMiddleware(eventMiddleware1, eventMiddleware2)

// Also you may listen the event using on function
// Listen all incoming events using wildcards
command.on('*', (event, api, options) => {
  // handle all event here
})

// Also you can specify what event to listen, you may use | to listen multiple events
command.on('message|message_unsend', (matches, event, api, options) => {
  // handle message and message_unsend event
})

// You can also listen initialized events
command.on('init', (api, options) => {
  // handle init event here
})

// You can also listen before the scripts restarted
// Why scripts should restart ? because we need to make new facebook home request inorder to get new session token, this will prevent from login state expiration.
command.on('restarting', (api, options) => {
  // handle before the script will be restarted
})

// Adding commands makes easy using chaining method.
command
  .add(async function (match, event, api) {
    // Handle inspire command here
    console.log(match) // { category: 'value here' }
  })
  .addName('inspire')
  .addDescription('Generate motivational quotes.')
  .addAlias('ins')
  .addUsage('/inspire')
  .addPattern('^(.*)$', ['category'])

// Adding global command middleware
const commandMiddleware1 = (next) => {
  return async (match, event, api, options) => {
    // Handle before the command is resolved
    await next(match, event, api, options)
    // Or handle after command has been resolved
  }
}

const commandMiddleware2 = (next) => {
  return async (match, event, api, options) => {
    // Handle before the command is resolved
    await next(match, event, api, options)
    // Or handle after command has been resolved
  }
}
command.addCommandMiddleware(commandMiddleware1, commandMiddleware2)
