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.

gRPC features and specs

  • Performance
    gRPC uses Protocol Buffers, which are more efficient in terms of serialization and deserialization compared to text-based formats like JSON. This leads to lower CPU usage and faster transmission, making it suitable for high-performance applications.
  • Bi-directional Streaming
    gRPC supports bi-directional streaming, enabling both client and server to send a series of messages through a single connection. This is particularly useful for real-time communication applications.
  • Strongly Typed APIs
    gRPC uses Protocol Buffers for defining service methods and message types, providing a strong type system that can catch potential issues at compile-time rather than runtime.
  • Cross-language Support
    gRPC supports a wide range of programming languages, including but not limited to Java, C++, Python, Go, and C#. This allows for flexible integration in polyglot environments.
  • Built-in Deadlines/Timeouts
    gRPC natively supports deadlines and timeouts to help manage long-running calls and avoid indefinite blocking, improving robustness and reliability.
  • Automatic Code Generation
    gRPC provides tools for automatic code generation from .proto files, reducing boilerplate code and speeding up the development process.

Possible disadvantages of gRPC

  • Learning Curve
    The complexity of gRPC and Protocol Buffers may present a steep learning curve for developers who are not familiar with these technologies.
  • Limited Browser Support
    gRPC was not originally designed with browser support in mind, making it challenging to directly call gRPC services from web applications without additional tools like gRPC-Web.
  • Verbose Configuration
    Setting up gRPC and defining .proto files can be more verbose compared to simpler RESTful APIs, which might be a deterrent for smaller projects.
  • HTTP/2 Requirement
    gRPC relies on HTTP/2 for transport, which can be problematic in environments where HTTP/2 is not supported or requires additional configuration.
  • Limited Monitoring and Debugging Tools
    Compared to REST, there are fewer tools available for monitoring, debugging, and testing gRPC services, which might complicate troubleshooting and performance tuning.
  • Protobuf Ecosystem Requirement
    Depending on the language, integrating Protocol Buffers might require additional dependencies and tooling, which could add to the maintenance overhead.

SignalR Alternatives
SignalR is basically used to allow connection between client and server or vice-versa. It is a type of bi-directional communication between both the client and server. SignalR is compatible with web sockets and many other connections, which help in the direct push of content over the server. There are many alternatives for signalR that are used, like Firebase, pusher,...

  • Building a CRUD app with React Query, TypeScript, and Axios
    We'll be using json-server to create the REST API that we'll fetch data from. In the root of the project, create a db.json file with the contents. - Source: dev.to / 12 months ago

    Our backend will be little more than a two-way translation layer between the database and the user interface (UI). Later in this post we will identify other responsibilities of a backend but our implementation will be kept simple to demonstrate the fundamental machinery and concepts. It is worth noting the backend comes in two parts, web server and application server. Both json-server and Express are able to... - Source: dev.to / almost 2 years ago
  • Improve Frontend-Backend development harmony with JSON-Server
    JSON-Server creates fake REST API with a minimum amount of configuration, it provides a simple way to create mock RESTful APIs and easily define the required endpoints, allows easy definition of the data schema in a JSON file and can serve as a reference for each figure in the project. - Source: dev.to / almost 2 years ago
  • Dictionary app
    I thought about usingJson Server (hosting the repo with the words on Github to begin with), Googlesheets, or maybe Firestore (i would prefer not to use it ,to avoid extra costs just in case it gets a reasonable amount of users). It isnt a big app so I just want a simple solution for storing the words and fetching them. Source: almost 2 years ago
  • Playwright - Not just for Frontend
    First, I didn't create a backend API for this example, but I used a fake API to test. I created it with json-server and json-server-auth. They are two npm packages that use a JSON file as a database and expose the database in an API. You can find more about json-server in its documentation and about json-server-auth here. - Source: dev.to / over 2 years ago
