Sails.js features and specs

  • MVC Architecture
    Sails.js follows a Model-View-Controller (MVC) pattern, making it easier to organize and maintain code, particularly for larger applications.
  • Auto-Generated REST APIs
    Automatically generates RESTful APIs based on your models, saving development time and reducing boilerplate code.
  • WebSocket Support
    Built-in support for WebSockets allows for real-time features without needing additional configurations.
  • ORM Integration
    Waterline, Sails.js' built-in ORM, provides a straightforward way to interact with databases, supporting multiple database systems with the same codebase.
  • Modularity
    Encourages modular development by supporting hooks and middleware, which can be reused or extended for various functionalities.
  • Blueprints
    Blueprints provide automatic actions for basic CRUD operations, streamlining common tasks and making development faster.
  • Scalability
    Designed to be scalable, allowing you to build applications that can handle a large number of simultaneous connections.

Possible disadvantages of Sails.js

  • Learning Curve
    Although Sails.js simplifies many aspects of development, there is still a learning curve, especially for those not familiar with Node.js.
  • Performance Overhead
    The abstractions provided by Sails.js and its ORM can introduce performance overhead, potentially making it slower than more lightweight frameworks.
  • Limited Flexibility
    While the conventions in Sails.js can speed up development, they can also limit flexibility, making it harder to implement customized or unconventional features.
  • Community and Support
    The community and support for Sails.js are not as extensive as some other frameworks like Express.js, which might make troubleshooting and finding solutions more challenging.
  • Outdated Documentation
    Some parts of the documentation may be outdated, which can lead to confusion and require additional time to find updated resources or examples.

FastAPI features and specs

  • High Performance
    Built on Starlette and Pydantic, FastAPI is one of the fastest frameworks for Python, providing high performance due to its asynchronous request handling.
  • Automatic Interactive API Documentation
    FastAPI automatically generates interactive API documentation via Swagger UI and ReDoc, which are very helpful for development and testing.
  • Type Checking and Validation
    With Pydantic models and Python type hints, FastAPI provides automatic data validation and type checking, reducing the chance of runtime errors.
  • Ease of Use
    Its syntax and design make it easy to learn for Python developers, offering a smooth development experience while reducing boilerplate code.
  • Asynchronous Support
    FastAPI supports asynchronous programming, allowing for better performance for I/O-bound operations, making it optimal for handling many simultaneous connections.
  • Extensive Documentation
    It has comprehensive and well-structured documentation, which is very useful for both beginners and advanced users.
  • Community and Ecosystem
    FastAPI has a growing community and ecosystem, with many plugins and integrations available to extend its functionality.

Possible disadvantages of FastAPI

  • Learning Curve for Asynchronous Programming
    Although FastAPI itself is easy to learn, grasping the concepts of asynchronous programming in Python can be challenging for beginners.
  • Complex Dependencies
    Using Pydantic for advanced validation can make the request models complex, requiring a deeper understanding of Pydantic and its functionalities.
  • Early Stage Libraries
    Some third-party libraries and extensions specifically tailored for FastAPI might still be in early stages of development and lack long-term stability.
  • Limited Real-World Examples
    Although the documentation is extensive, there might be limited real-world examples and case studies readily available compared to more mature frameworks.
  • Deployment Complexity
    Deploying FastAPI applications might be more complex in comparison to traditional synchronous frameworks, mainly due to the need for asynchronous server setups.

  • AdonisJS
    I haven't used either so I can't chime in on that front, but long ago I was pretty into Sails which is written by a team that loves rails, but switched to NodeJS so it's basically Node on Rails. I actually thought they discontinued it, but I just searched and it still exists. It was a solid framework like 5 years ago when I used it last so I assume it's quite mature now. https://sailsjs.com/. - Source: Hacker News / 11 months ago
