JSON Server features and specs

• Ease of Setup
  JSON Server can be set up quickly with minimal configuration, making it ideal for prototyping and rapid development. It allows developers to have a fully functioning REST API within minutes.
• RESTful API
  It provides a standard RESTful API out of the box, allowing developers to perform all CRUD operations. This is helpful for simulating a real-world server while testing client-side applications.
• Customization
  JSON Server supports middlewares, routes, and custom rules, allowing developers to customize the behavior and structure of the API to better suit their needs.
• Fakes Backend Data
  It's great for simulating backend responses without needing a real backend setup, useful in front-end development to test components and interactions.
• Lightweight
  As a lightweight server, it requires fewer resources and is quite simple compared to setting up a full-fledged backend server.

Possible disadvantages of JSON Server

• Not for Production
  JSON Server is designed for development and testing. It is not suitable for production use due to performance limits and lack of robust security features.
• Limited Functionality
  While JSON Server is great for basic CRUD operations, it lacks advanced features like authentication, authorization, and complex querying.
• Data Persistence
  Data is stored in a JSON file, and while this is convenient for testing, it is not suitable for applications that require persistent and scalable data storage.
• In-memory Limitations
  Being an in-memory server, it may have issues with handling large datasets or complex data structures efficiently.
• Manual Data Reset
  Any changes made to the JSON file while the server is running require manual resets or reloads to reflect in the API, which can be cumbersome during continuous development cycles.

GraphQL features and specs

• Efficient Data Retrieval
  GraphQL allows clients to request only the data they need, reducing the amount of data transferred over the network and improving performance.
• Strongly Typed Schema
  GraphQL uses a strongly typed schema to define the capabilities of an API, providing clear and explicit API contracts and enabling better tooling support.
• Single Endpoint
  GraphQL operates through a single endpoint, unlike REST APIs which require multiple endpoints. This simplifies the server architecture and makes it easier to manage.
• Introspection
  GraphQL allows clients to query the schema for details about the available types and operations, which facilitates the development of powerful developer tools and IDE integrations.
• Declarative Data Fetching
  Clients can specify the shape of the response data declaratively, which enhances flexibility and ensures that the client and server logic are decoupled.
• Versionless
  Because clients specify exactly what data they need, there is no need to create different versions of an API when making changes. This helps in maintaining backward compatibility.
• Increased Responsiveness
  GraphQL can batch multiple requests into a single query, reducing the latency and improving the responsiveness of applications.

Possible disadvantages of GraphQL

• Complexity
  The setup and maintenance of a GraphQL server can be complex. Developers need to define the schema precisely and handle resolvers, which can be more complicated than designing REST endpoints.
• Over-fetching Risk
  Though designed to mitigate over-fetching, poorly designed GraphQL queries can lead to the server needing to fetch more data than necessary, causing performance issues.
• Caching Challenges
  Caching in GraphQL is more challenging than in REST, since different queries can change the shape and size of the response data, making traditional caching mechanisms less effective.
• Learning Curve
  GraphQL has a steeper learning curve compared to RESTful APIs because it introduces new concepts such as schemas, types, and resolvers which developers need to understand thoroughly.
• Complex Rate Limiting
  Implementing rate limiting is more complex with GraphQL than with REST. Since a single query can potentially request a large amount of data, simple per-endpoint rate limiting strategies are not effective.
• Security Risks
  GraphQL's flexibility can introduce security risks. For example, improperly managed schemas could expose sensitive information, and complex queries can lead to denial-of-service attacks.
• Overhead on Small Applications
  For smaller applications with simpler use cases, the overhead introduced by setting up and maintaining a GraphQL server may not be justified compared to a straightforward REST API.
