  1. Overview of Testing in NestJS

    NestJS emphasizes testing to ensure application quality and stability. It primarily uses two types of tests:

    • Unit Tests: Verify individual units of code such as functions, methods, or services in isolation.
    • Integration Tests (E2E): Evaluate the interaction between different components, including controllers, services, and the database.

    Default Tooling:

    • Jest: The default testing framework for unit and integration tests.
    • Supertest: Recommended for testing HTTP integration endpoints.

  2. Overview of React Router and its core problems solved

    React Router is the standard routing library for React applications. It synchronizes the UI with the URL, supports nested routes, manages browser history, and enables programmatic navigation. It specifically solves:

    • Avoiding full page reloads during navigation (SPA experience).
    • Using the URL as the single source of truth for application state/location.
    • Implementing nested routes and layout composition via Outlets.
    • Declarative data loading (loaders) and form submissions (actions) within the route context.
    • Managing navigation states (pending, submitting) and concurrent fetches.

  3. Overview of React Router and its core purpose

    React Router is the standard routing library for React applications. It synchronizes the UI with the URL, supports nested routes, manages browser history, and enables programmatic navigation. It specifically solves problems related to avoiding full page reloads (SPA experience), maintaining the URL as the source of truth for application state, and providing declarative data loading and mutation within the context of routes.

  4. Overview of Git version control

    Git is a distributed version control system designed for speed and efficiency in large projects. It tracks file changes, enables collaboration among multiple developers without overwriting work, and allows reverting projects to previous states. Unlike some systems that store differences, Git stores snapshots of the file state at each commit, creating a pointer to the previous commit for efficient tracking.

  5. Overview of Zustand state management

    Zustand is a lightweight (~2.5KB), simple, and flexible state management library for React applications. It allows for centralized global state without the boilerplate complexity of Redux or MobX. Key features include a minimalist syntax, automatic reactivity, TypeScript support, and compatibility with middleware, devtools, and persistence.

  6. Overview of Postman for API Testing

    Postman is a tool used to test and validate HTTP APIs (REST or GraphQL). It allows backend developers to verify endpoint functionality, automate tests, and document services. Key advantages include a visual interface for inspecting requests/responses, support for all standard HTTP methods, and integration with Newman for CI/CD pipelines.

  9. Overview of React Router and its core problems solved

    React Router is the standard routing library for React applications. It synchronizes the UI with the URL and enables several key capabilities:

    • Prevents full page reloads during navigation (SPA experience).
    • Uses the URL as the single source of truth for application state and location.
    • Supports nested routes and layout composition via Outlets.
    • Provides declarative data loading (loaders) and data mutation (actions) within the route context.
    • Manages navigation states (pending, submitting) and concurrent fetches via useFetcher.

  10. Overview of React Router and its core problems solved

    React Router is the standard routing library for React applications. It synchronizes the UI with the URL and supports nested routes, browser history management, and programmatic navigation. It specifically solves:

    • Avoiding full page reloads in Single Page Applications (SPAs).
    • Using the URL as the single source of truth for application state/location.
    • Implementing nested routes and layout composition via Outlets.
    • Declarative data loading (loaders) and form submissions (actions).
    • Managing navigation states (pending, submitting) and concurrent fetches.

  11. Overview of Spec-driven Development (SDD)

    Spec-driven Development (SDD) is a methodology that centers the software construction process on precise and structured requirement definitions. Unlike traditional approaches where documentation is a byproduct, in SDD, the specification drives the development. This approach is particularly effective for AI-native development, providing Large Language Models (LLMs) with a 'source of truth' to reduce hallucinations and technical debt, ensuring generated code aligns with business goals.

  12. Overview of NestJS Pipes

    Pipes are NestJS features used to transform and validate input data within controller routes. They can be applied at the method level, controller level, or globally across the application. Pipes are annotated with the @Injectable() decorator and must implement the PipeTransform interface, which requires a transform() method. The transform() method accepts two arguments: value (the data to be transformed/validated) and metadata (contextual information such as expected data type and location of the value).
