github-diff-email

A webhook for GitHub's push events to provide a unified diff in an email. Created as a Lambda function to be used with API Gateway.

For some additional information on some settings in AWS head over here: http://www.tonytruong.net/getting-github-unified-diff-emails-using-aws-lambda-and-api-gateway/

Serverless version here which will do all the heavy lifting for deployment: https://github.com/serinth/serverless-github-diff-emailer

Requirements:

AWS Lambda currently supports up to version 4.3.2 but I've built this and packaged it on 5.7+ so that should be fine.

• API Gateway full access
• IAM Execution Role creation access
• Lambda full access
• SMTP server credentials

Make sure you modify the config.json: If you're on a secure connection already to the mail server then:

1. Make username and password blank
2. Check to see if you're using port 25 (the default for non secure channel)

{
    "mailConfig":{
        "host": "SMTP SERVER",
        "username": "USERNAME",
        "password": "PASSWORD",        
        "to": "[email protected],[email protected]",
        "port": 465,
        "secure": true,
        "requireTLS": true,
        "authMethod": "LOGIN"
    },
    "github":{
        "secret": "github web hook secret"
    }
}

Overview of How to Deploy

The high level overview of what you need is:

1. Clone this repository and use npm install --save and zip up the contents including node_modules
2. Create the API Gateway endpoint and point to a lambda function
3. Create the lambda function using the zip file you created with this code
4. Create an IAM Execution role for the lambda function and give the API Gateway permissions to invoke this function
5. Point the API Gateway endpoint to use this lambda function
6. Apply pass-through mappings on the API Gateway so the lambda function can access the headers and body. Use the provided body-mapping for 'application/json' from AWS in the dropdown. It should look similar to this:
