React Complex Tree features and specs

  • Customizability
    React Complex Tree offers a high degree of customizability, allowing developers to tailor the tree component to fit their specific needs. This can be especially useful for creating unique UI experiences.
  • Feature-Rich
    The library includes a wide range of features out of the box such as drag-and-drop support, keyboard navigation, and dynamic data loading, which can save development time.
  • Accessibility Support
    React Complex Tree is designed with accessibility in mind, providing support for ARIA attributes and keyboard interactions, which helps ensure that applications are usable by people with disabilities.

    The library has a supportive community and well-structured documentation, providing developers with ample resources to troubleshoot and extend its functionality.

Possible disadvantages of React Complex Tree

  • Complexity
    Due to its extensive features and customizability, React Complex Tree can be complex to set up and configure properly, which may lead to a steeper learning curve for new users.
  • Bundle Size
    As a feature-rich component, React Complex Tree can increase your bundle size, which might be a concern for projects where performance and loading time are critical.
  • Third-Party Dependency
    Relying on a third-party library introduces dependencies outside of your control, which may present challenges in terms of long-term maintenance and potential update or deprecation issues.
  • Specific Use Case Tailoring
    While it offers a lot of features, developers may find that very specific use cases require additional effort to customize or extend the component beyond its intended use.

  • Pegasus Mail Newsflashes
    Iโ€™ve gone through this process for my email client Kanmail [1]. The third party audit is not required for email clients that run on end users computers and store credentials locally. By the looks of it Pegasus falls into this category and should not have any issues getting approved (still need the YT video and such but the Google team are surprisingly responsive and helpful in my experience).

  • Ask HN: Anyone making a living building desktop applications?
    Iโ€™m building a desktop email client [0] that has $45 lifetime licenses. Made to scratch my own itch Iโ€™ve been using it as my only client for 4 years now, barely makes any money though! [0] https://kanmail.io. - Source: Hacker News / over 4 years ago
  • Compile Python applications into stand-alone executables
    I use pyinstaller for my Kanmail email client [1] and itโ€™s fantastic, but at creating Mac app bundles or Windows exes. Tried making actual standalone binaries for another project and, as others have mentioned, theyโ€™re incredibly slow to startup. Still, I am a huge fan of the project and it makes it possible to make webview desktop โ€œappsโ€ (like or hate them) with Python. [1] https://kanmail.io. - Source: Hacker News / over 4 years ago
  • How do you create a cross-platform GUI without using Electron?
    There's pywebview (https://github.com/r0x0r/pywebview/) which is a Python lib that uses whatever native webview implementation exists. Obviously means some compatibility work between each OS, but gives out very small apps what work very well on the whole. I'm using it on my cross platform email client (https://kanmail.io). - Source: Hacker News / almost 5 years ago
