Lambda Form

Lambda from is an example module to show how a Drupal Form can be connected to a lambda function in order to handle the form in a serverless way.

This is a proof of concept to be extended in real world static projects built using Tome module.

Contents

• Drupal module providing a basic contact form
• Serverless Lambda function. It sends an email with the data entered in the from above.

Setup

Lambda function

This repository contains a serverless folder where it is included the serverless template and the nodejs code of a basic lambda function.

In order to deploy this lambda function, you need to have an AWS account and serverless installed in your machine.To setup serverless you need to:

• Install the serverless framwork npm i -g serverless
• Setup your AWS CLI credentials in ~/.aws/credentials file

Then it is necessary to configure the app. You need to rename secrets.example.json to secrets.json and replace the variables.

Finally run serverless deploy. If everything goes well, you will get the URL of the lambda endpoint. Something like https://{id}.execute-api.{region}.amazonaws.com/{stage}/email/send. This URl Will be used in the Drupal module to connect both parts.

NOTE: This is a very brief summary. It is encouraged to read this post , from where I took most of the ideas to build this function.
