In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
serverless-fb-messenger
Advanced tools
Node client for Facebook Messenger:
This is an ongoing project, the API isn't fully compatible with Messenger just yet. There is currently no support for webviews, while there is very limited support for account linking and message read events.
The API has very good support for postbacks, buttons and quick replies for text, image and share messages.
npm install lambda-fb-messenger
Here's how you can use serverless-fb-messenger
in a Lambda to quickly send messages to a user, and receive all messages.
const ServerlessFbMessenger = require( "serverless-fb-messenger" );
exports.handler = function ( event, context, respondToMessenger ) {
// Instantiate serverless-fb-messenger
const sfm = new ServerlessFbMessenger( {
"pageAccessToken": <PAGE_ACCESS_TOKEN>,
"verifyToken": <VERIFY_TOKEN>
});
// Send a message
sfm.sendMessage({
"userId": <USER_ID>,
"message": "How you doing?"
});
// Log messages from all users
sfm.on( "message", ( userId, message ) => {
console.log( `The user ${userId} said "${message}" );
});
// Tell server-less-fb-messenger to start listening
sfm.init( event, context, respondToMessenger );
});
There are two steps to working with serverless-fb-messenger
:
pageAccessToken
and verifyToken
.const ServerlessFbMessenger = require( "serverless-fb-messenger" );
const sfm = new ServerlessFbMessenger( {
"pageAccessToken": <PAGE_ACCESS_TOKEN>,
"verifyToken": <VERIFY_TOKEN>
});
exports.handler = function ( event, context, respondToMessenger ) {
sfm.init( event, context, respondToMessenger );
});
Basic
sfm.sendMessage({
"userId": <USER_ID>,
"message": "How are you doing?"
});
With quick replies
sfm.sendMessage({
"userId": <USER_ID>,
"message": "How are you doing?",
"quickReplies": [{
"text": "I'm good",
"postback": "USER_IS_GOOD" | { "user_is": "good" }
}]
});
With buttons
sfm.sendMessage({
"userId": <USER_ID>,
"message": "How are you doing?",
"buttons": [{
"text": "I'm good",
"postback": "USER_IS_GOOD" | { "user_is": "good" }
}]
});
Basic
sfm.sendImage({
"userId": <USER_ID>,
"url": "http://foo.com/bar.gif"
});
With quick replies
sfm.sendMessage({
"userId": <USER_ID>,
"url": "http://foo.com/bar.gif",
"quickReplies": [{
"text": "I'm good",
"postback": "USER_IS_GOOD" | { "user_is": "good" }
}]
});
Basic
sfm.sendShareMessage({
"userId": <USER_ID>,
"title": "Working with Facebook Messenger",
"subtitle": "By Tom Maslen",
"imageUrl": "http://foo.com/bar.gif"
});
With buttons
sfm.sendShareMessage({
"userId": <USER_ID>,
"title": "Working with Facebook Messenger",
"subtitle": "By Tom Maslen",
"imageUrl": "http://foo.com/bar.gif",
"buttons": [{
