Create a front end in S3 that allows a user to enter a parking lot number (1-20), and a number of available spots. You don’t need to do any error checking on these values. Pass the values through API gateway and insert them in your DynamoDB database
Answer
Designing a front end in AWS S3 that enables users to input parking lot details and pass them through API Gateway for insertion into DynamoDB database involves several steps. In this analysis, we will explore the necessary components and their configurations to accomplish this task.
1. Front End Design:
The first step is to create a front end in AWS S3. AWS S3 is a scalable object storage service that allows for web hosting. To design the front end, we can use HTML, CSS, and JavaScript.
The design should include an input field for the parking lot number and another input field for the number of available spots. Additionally, we can add a submit button to trigger the sending of these values to the backend. CSS can be used to style the front end elements according to the desired design aesthetic.
2. API Gateway Configuration:
API Gateway acts as a bridge between the front end and the backend services. We need to configure API Gateway to receive and forward the parking lot details to our backend service for processing.
To configure the API Gateway, we need to define an API endpoint that our front end will send data to. We can choose the REST or GraphQL API type based on our requirements. For the purpose of this task, a REST API is sufficient.
Once the API endpoint is created, we can define a POST method to handle incoming data from the front end. In the integration settings, we can choose to integrate with the Lambda function that handles the processing and insertion of data into DynamoDB.
3. Lambda Function Implementation:
A Lambda function is required to handle the data received from API Gateway and insert it into the DynamoDB database.
In the Lambda function, we need to define the necessary code logic to extract the parking lot number and available spots from the API request. This can be achieved using a node.js or python runtime environment.
Once the values are extracted, we can use the AWS SDK to connect to the DynamoDB service and execute the desired insert operation. The Lambda function should handle any potential errors that may occur during the process and provide appropriate responses.
4. DynamoDB Configuration:
Before inserting data into DynamoDB, we need to create a table to store the parking lot details. The table should have appropriate attributes and a primary key for efficient querying and retrieval.
The AWS DynamoDB console allows us to create and manage tables easily. We can define the desired attributes such as parking lot number and available spots, as well as any additional information we want to store.
In conclusion, implementing a front end in AWS S3 that passes parking lot details through API Gateway and inserts them into DynamoDB involves creating a front end design in S3, configuring API Gateway to handle the incoming data, implementing a Lambda function to process and insert the data into DynamoDB, and configuring DynamoDB with appropriate table settings. Following these steps will enable the seamless flow of data from the front end to the database.
