  4. GraphQL

    GraphQL, developed by Facebook, is a query language for APIs and a runtime for executing those queries. Unlike REST, GraphQL allows clients to request exactly the data they need, reducing over-fetching and under-fetching of data. This makes it highly efficient for modern applications that require rapid, flexible data retrieval. As GraphQL continues to replace REST in many projects, mastering it is becoming increasingly important for developers working with APIs.

    • Effective Data Acquisition: Clients using GraphQL can request just the data they require—neither more nor less. This results in less network utilization and more effective data retrieval by avoiding the over- and under-fetching problems that are frequently seen with REST APIs.

    • One Point of Contact: All queries in GraphQL are sent to a single endpoint, which streamlines API architecture and lessens the hassle of maintaining numerous endpoints as in conventional REST APIs.

    • Robustly Typed Diagram: A schema that outlines the various types of data and their relationships defines GraphQL APIs. The documentation provided by this type system is exact and easy to read, which facilitates developers' understanding and utilization of the API.

  5. Micro Frontends

    Micro frontends extend the microservices concept to the frontend, allowing developers to break down a web application into smaller, independently deployable modules. This approach promotes code reusability, parallel development, and easier maintenance. Technologies like Module Federation in Webpack 5 facilitate the implementation of micro frontends. As applications grow in complexity, understanding micro frontends will be essential for developers aiming to maintain modular, scalable architectures.
