Welcome to Boutique, a software development company that’s working on a project to automate a client’s inspection process. As a software engineer, your task is to create an HTTP API for the project. You’ll set up an ASP.NET Core web host, implementing the first endpoint according to the OpenAPI specification. To verify the endpoint works as intended, you’ll add integration tests, and you’ll use Swashbuckle and API versioning middleware to enable future functionality. When you’re done, you’ll have firsthand experience with important tools—including Postman and Swagger UI—and an API that’s ready for further development.

The development team at Boutique, a software company, is working on a project for automating the inspection process of a client that builds industrial robots. An ASP.NET Core HTTP API has already been set up, and the team has started implementing the domain model entities and persisting them to a SQL database. As part of the team, your task is to implement CRUD (create, read, update, and delete) endpoints for all the entities according to the OpenAPI specification. To achieve persistence, you’ll configure Entity Framework Core and register it in the dependency injection container. You’ll implement a custom JSON converter to support polymorph endpoints in order to handle different types of robots. To verify that your implementation is correct, you’ll write and perform integration tests.

Boutique, a software development company, is working on a project that will automate a client’s inspection process. As a software engineer for Boutique, your task is to implement authentication and authorization in the existing ASP.NET Core HTTP API for the project according to the client’s requirements. You’ll register your application to use Google as an identity provider, configure Swashbuckle to support authentication through Google, and activate the authentication and authorization middleware of ASP.NET Core. To take advantage of ASP.NET Core’s authorization features, you’ll add additional claims to the authenticated identity per the client’s specs, and you’ll implement role- and policy-based authorization as needed. When you’re done, employees will be able to use all of the API’s functionality, and customers will have read access to their own data.

As a software engineer for Boutique, a software development company, you're tasked with adding search, upload, and download functionality to an ASP.NET Core HTTP API that Boutique is building for its client, RobotsInc. To enable the frontend to navigate through existing data structures, you’ll add several child endpoints, as well as an endpoint for criteria-based searches. You’ll also implement endpoints for binary photo uploads and downloads according to the OpenAPI specification, and you’ll verify your implementations are correct by testing manually with Swagger UI as well as with automated integration tests. When you’re finished, RobotInc’s employees will be able to upload photos and notes to document and report on their robot inspections.

Boutique, a software development company, has a fully functional ASP.NET Core HTTP API for a client’s project. As a software engineer for Boutique, it’s your job to improve the API’s code and prepare it for production. Using Serilog, you’ll add logging functionality to help determine the causes of issues that may arise in production. To allow the web UI to be hosted someplace other than your HTTP API, you’ll enable cross-origin resource sharing (CORS) middleware. You’ll create custom middleware for handling the cross-cutting concern of database transactions. To further improve the quality of the codebase, you’ll create a custom filter that handles business exceptions in a general, consistent way. When you’re done, the API will be robust, easy to maintain, and production-ready.
