Pyjs features and specs

  • Cross-platform Compatibility
    Pyjs allows developers to write a single web application codebase in Python, which can then be compiled into JavaScript. This cross-compilation means the application can run on any device with a web browser, enhancing its reach.
  • Python Syntax
    Developers familiar with Python can leverage their existing knowledge to write web applications without learning JavaScript. This can lead to faster development times and reduced learning curves.
  • Rich Widget Set
    Pyjs offers a rich set of pre-built widgets that can be used to create complex user interfaces easily. This helps in speeding up the development process and ensures consistency across the application.
  • Client-side Execution
    By compiling Python code to JavaScript, Pyjs enables client-side execution of applications, potentially reducing server load and improving user experience through quicker interactions.

Possible disadvantages of Pyjs

  • Performance Overhead
    The extra layer introduced by compiling Python to JavaScript can lead to performance issues, especially for larger applications, as JavaScript is inherently faster and more optimized for web environments.
  • Limited Ecosystem
    Compared to more mature frameworks and libraries in the JavaScript ecosystem, Pyjs has a smaller community and fewer resources available, which can pose challenges in terms of finding support and third-party integrations.
  • Debugging Complexity
    Debugging can become complex as developers must understand both the Python source code and the resulting JavaScript output, making it harder to trace and resolve issues.
  • Stagnant Development
    Pyjs has not seen active development or community engagement compared to other frameworks, which could impact its long-term viability and the availability of updates or security patches.

Transcrypt features and specs

  • Python to JavaScript Transpilation
    Transcrypt allows you to write your code in Python, which is then transpiled into JavaScript. This enables Python developers to leverage their existing knowledge and skills to develop web applications.
  • Efficiency and Performance
    Transcrypt produces highly readable and compact JavaScript code, which can be optimized for better performance. The generated code includes optional source maps for debugging.
  • Access to JavaScript Libraries
    Transcrypt allows you to use JavaScript libraries seamlessly alongside Python code, enabling integration with existing JavaScript ecosystems.
  • Static Typing
    Transcrypt supports optional static typing, which can help catch errors earlier in the development cycle and make your code more robust.
  • Advanced Features
    Transcrypt supports advanced Python features such as multiple inheritance, tuple assignment, and list comprehension, providing a rich development experience.

Possible disadvantages of Transcrypt

  • Limited Python Support
    Only a subset of Python's standard library is supported, which might limit functionality that can be directly transpiled without modifications.
  • Compatibility Issues
    Certain Python constructs and idioms may not translate well into JavaScript, requiring developers to adapt their code specifically for web environments.
  • Learning Curve
    Although it enables Python development for the web, developers need to learn about the limitations and specifics of the transpilation process, which can be a barrier.
  • Community and Support
    Transcrypt has a smaller community compared to mainstream JavaScript frameworks, which can make finding support and resources challenging.
  • Development Overhead
    Transcrypt introduces an additional step in the build process, which might increase the complexity of the development and deployment workflow.

  • How to actually use python code in browser or application?
    I have a Python program that takes user input from the console and shows some results on the console, and I want the user to be able to type stuff into it instead of pre-recorded runs. How do I do that? I'm not really sure. You could have a copy of Python running on the server and have the front-end communicating with it, but you'd have to be sure it's secured -- there are a lot of dangerous Python commands...

  • PyScript
    This is a laudable effort, but I'm not a fan of shipping the entire interpreter. I looked around a few weeks ago and found https://transcrypt.org, which compiles your Python script to JS, so size is minimal. It's great for shipping small, internal tools/apps, I love how maintainable they are by all the Python devs, plus they're very fast to load and execute. - Source: Hacker News / over 3 years ago
  • PySketch: Python Playground for HTML5
    How is the Python being run by the browser? Several impressive projects bring Python to the browser, such as Brython, Transcrypt, Skulpt, Pyodide. PySketch uses Brython that compiles Python to JavaScript in the browser. You can take a look at this article about technologies and comparisons if you want to learn more. - Source: dev.to / over 3 years ago

  • Use of python for software development
    For web apps: in my experience, there are tools that convert Python into JavaScript or try to make Python run inside a web browser like Brython and Transcrypt. These have been VERY awkward or painfully slow, so I would strongly discourage their use in practical web development. Source: over 4 years ago
  • Python and the Browser - Revisited
    A while back, I posted about my initial foray into using Python to develop front-end web applications with React by using the Transcrypt transpiler. Python in the Browser Part of the initial learning process I went through was doing the official React tutorial, but using Python for the code instead of JavaScript. When I did that, I adhered to the structure of the application that was used in the tutorial... - Source: dev.to / almost 5 years ago
