Backend Coding Test

Test 1

• Fork and clone this project locally then begin the test in the repo.

• Following the serverless architecture and the microservice principles, set up a backend using both the Middy and Serverless Framework that will be deployed to AWS Lambda.

• Project should be in typescript

• Follow the Functional programming (FP) technique

• Set up a GraphQL API layer using Hasura with a PostgreSQL Database

• All interactions with the database should be through the GraphQL API

• Implement & use graphql-request to interact with with the GraphQL API

• Setup middlewares using middy that would commonly be used for security, logging & data validation.

• Complete the pricing_algo.ts script and make it accessible through an API.

• Create a blog table with a thousand generated articles that consist of a title, content, author, create_at, updated_at.

• Develop a public REST API route that returns a paginated list of blog articles. The implementation should use GraphQL Relay Cursor-based pagination method.

• Implement full-text fuzzy search with Hasura GraphQL API and Postgres for all blogs where their title & content are searchable. Expose an API to interact with the functionality.

• Deploy each route to its own Lambda function using the Serverless Framework. Do note you can use the Serverless Framework without the serverless cloud service.

Extra Points

• Implement code/typescript generation based on the GraphQL API

• Generate an OpenAPI documentation for all routes

Good Job!
