AWS Lambda Extension for Probot
A Probot extension to make it easier to run your Probot Apps in AWS Lambda.
$ npm install @probot/serverless-lambda
// handler.jsconst serverless = ;const appFn = ;moduleexportsprobot = ;
This package moves the functionality of
probot run into a handler suitable for usage on AWS Lambda + API Gateway. Follow the documentation on Environment Configuration to setup your app's environment variables. You can add these to
.env, but for security reasons you may want to use the AWS CLI or Serverless Framework to set Environment Variables for the function so you don't have to include any secrets in the deployed package.

Since Lambda functions do not start a normal node process, the best way we've found to test this out locally is to use
serverless-offline. This plugin for the serverless framework emulates AWS Lambda and API Gateway on your local machine, allowing you to continue working from
https://localhost:3000/probot before deploying your function to AWS.
Long running tasks
Some Probot Apps that depend on long running processes or intervals will not work with this extension. This is due to the inherent architecture of serverless functions, which are designed to respond to events and stop running as quickly as possible. For longer running apps we recommend using other deployment options.
This extension is designed primarily for receiving webhooks from GitHub and responding back as a GitHub App. If you are using HTTP Routes in your app to serve additional pages, you should take a look at
serverless-http, which can be used with Probot's express server by wrapping
