The GREENEATS Food Ordering System is a serverless, scalable, and cost-efficient solution that streamlines food ordering. Customers can fill out a google form to place orders, order entries will be logged in google forms and they will receive a real-time notifications. The system leverages AWS cloud services to ensure high availability, fault tolerance, and seamless order management. By integrating API Gateway, Lambda, SQS, SNS, and MongoDB, the system automates order processing and optimizes customer experience.

pre-requisites for this project

• An AWS Free-tier Account
• A google email
• Some Knowledge of AWS Services such as AWS API Gateway, AWS Lambda, AWS SQS, SNS , DynamoDB, AWS IAM
• Prompting Skills for troubleshooting
• Some Knowledgr of Google AppScript

follow the steps below accordingly

step 1 : Creating A Google Form

if you have a google email account you can create a google form using this link (https://docs.google.com/forms/u/0/) and use the order form template or you can create your form ideas from scratch

step 4: Creating the AWS lambda Function

in your aws management console, go to lambda function, and create a python lambda function.

step 5: create an AWS API Gateway

In your aws management console, create an aws api gateway. This api gateway will be used to fetch sheets enteries from Google sheets through the Appscript. T to get the invoke Url go to the stage menu and check the checklist icon to view the invoke URL. attach the invoke URL to the Appscript. Ensure you append /stage/route add the end of the const url variable path.

const url = 'https://6md9guki2g.execute-api.us-east-1.amazonaws.com/default/greeneats';

step 6: Create an SQS Queue

in the management console, create an sqs queue which will be used to create a queue of orders collected from the api gateway when the lambda function is invoked. the SQS URL will look like this:

https://sqs.us-east-1.amazonaws.com/814647154673/Greeneatsqueue.fifo

Step 7: Create an SNS Topic

head over to the AWS management console to create an SNS topic.
