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.

Evil features and specs

  • Vim Emulation
    Evil provides a near-complete emulation of Vimโ€™s features within Emacs, allowing users who are familiar with Vim to transition without losing their preferred keybindings and workflow.
  • Customizability
    Evil allows users to customize their configurations extensively, combining the powerful text-editing capabilities of Vim with the customizability of Emacs.
  • Community Support
    Evil has a large and active community, providing a wealth of plugins and resources to enhance the text editing experience.
  • Mode Integration
    Evil integrates smoothly with various Emacs major and minor modes, allowing users to leverage the full functionality of Emacs alongside Vim's modal editing.

Possible disadvantages of Evil

  • Learning Curve
    For users unfamiliar with Vim, the modal editing approach can introduce a significant learning curve, particularly for those accustomed to traditional text editors.
  • Complex Configuration
    Configuring Evil to fully integrate with existing Emacs setups can be complex and time-consuming, especially when customizing keybindings and behaviors.
  • Performance
    In some cases, using Evil with certain Emacs configurations or plugins may lead to performance issues, such as lag or delayed responses.
  • Inconsistencies
    There might be inconsistencies between Evilโ€™s implementation of Vim features and the original, which could affect workflows for power users who rely on specific Vim functionalities.

  1. Kurslog team
    ยท Working at Kurslog ยท

    When our backend team needs to build services for data parsing, aggregators, or high-load APIs, FastAPI is our absolute go-to choice. It completely lives up to its name-development speed is outstanding.

    The combination of Pydantic for data validation and built-in async support keeps our shared codebase clean, strictly typed, and reliable. But the biggest highlight for our cross-functional team is the automatic generation of interactive OpenAPI (Swagger) documentation. Our frontend and mobile developers no longer have to wait for backend engineers to manually update API docs; everything stays perfectly in sync automatically. It has drastically improved our team's communication and delivery speed.

  • Switching from the Mac port Build of Emacs to the Standard NS Build
    That said, the default for sis-context-hooks, which decides when it fires, is '(evil-insert-state-entry-hook), which assumes evil. If you don't use evil, this hook never gets called and it won't work, so you'll need to add hooks that match your own workflow. - Source: dev.to / about 1 month ago
