Possible disadvantages of CodePen

  • Limited Offline Functionality
    Since CodePen is primarily an online tool, it requires an internet connection for most of its features to work, limiting its usefulness in offline environments.
  • Performance Constraints
    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.
  • Security Concerns
    Sharing projects with the public can expose your code and assets to unauthorized use, posing potential intellectual property and security risks.

Markdown-it features and specs

  • High Performance
    Markdown-it is designed for fast processing, making it suitable for applications where performance is crucial.
  • Extensibility
    Markdown-it offers a plugin system that allows developers to extend its core functionality with custom rules and plugins.
  • CommonMark Support
    Markdown-it fully supports the CommonMark specification, ensuring consistent rendering across different platforms.
  • Full-featured
    It includes a lot of built-in features like support for tables, footnotes, and more advanced Markdown formatting options.
  • Easy to Customize
    With a wide range of configurations, developers can easily customize the parser to fit their specific needs.

Possible disadvantages of Markdown-it

  • Size
    Being feature-rich and extensible may result in a larger library size, which might not be ideal for all projects, especially those with strict size limitations.
  • Complexity
    For users who need a simple markdown parser, Markdown-it’s extensive features and configuration options might be overwhelming.
  • Learning Curve
    Utilizing its full potential requires learning and understanding its plugin architecture and customization options, which could be challenging for beginners.
  • External Dependencies
    Relying on plugins may introduce external dependencies that need to be managed and maintained.

  • Rendering Markdown with Enhance
    Enhance does not natively support rendering markdown into HTML, which is out of scope for the project. Instead, we rely on markdown-it, an excellent JavaScript markdown parser that is endlessly configurable with plugins. As we use markdown in many different projects, we’ve created a node module called, Arcdown, which packages together our preferred conventions for parsing markdown files. - Source: dev.to / over 2 years ago

  • Adding Markdown Support to a Static Site Generator
    For my own static site generator, Jellybean, one feature of Docusaurus that I wanted to implement was full markdown support. This is because my static site generator previously only had partial markdown support, which is not very user-friendly. Thankfully, there are a some great open-source libraries which can provide full markdown support and I decided to use markdown-it for my project. - Source: dev.to / over 3 years ago
