# AWS SAM app with MongoDB Atlas Data APIs

This is the implementation of a typical web app backend where the MongoDB Atlas is leveraged to store data.

### Overview of My Submission
The SAM app uses MongoDB Atlas for database choice which contains two collections - `shield_agents` and `shield_locations`. This stores the S.H.I.E.L.D info such as the database of all agents and non classified locations. The operation of `INSERT` and `GET` is integrated with [MongoDB Atlas Data APIs](https://docs.atlas.mongodb.com/api/data-api/) where the API credentials are created and passed into AWS Lambda fns as *environment variables* with CloudFormation Parameters. The APIs from SAM app are exposed with *AWS API Gateway*. Also have the Search enabled with indexes.

### Submission Category: 
**Choose Your Own Adventure**, the first time I'm using MongoDB and Data APIs so went a step to adapt it into my usual tech-stack (AWS Serverless) with a [AWS SAM application](https://aws.amazon.com/serverless/sam/).

[MongoDB Atlas Search](https://docs.atlas.mongodb.com/atlas-search/) helps in creating an `index` for a collection and using the index to query and check if the filter pattern matches any record. The matching records also return a match score.
