Best GUI frameworks for Go
The go-gtk package is a Go binding for the GTK toolkit. The package enables Go developers to use the GTK library in Go with similar features as the GTK library. The package is performant, well-documented, and actively maintained. The go-gtk package depends on the GTK library to function, and youโ€™ll need to have GTK installed on your machine to build GUI applications in Go....

  • What GNOME needs to progress faster? (More contributors, money, better docs etc.)
    Wha? An example of a barebones GTK JavaScript app is right there on the front page. One click on the bindings link, will send you to the official GNOME-hosted GitLab repo for gjs, which in-turn, has links to official API documentation. Source: almost 4 years ago
  • GTK 4 & JavaScript - how to start?
    I think what is lacking is a kind of introduction similar to what you have written in your post now. Myself, I am totally new to GTK. I come as a user of Gnome. All I knew until today was that to develop applications for Gnome, preferably I should use something called GTK. And I heard so much about the recent version that came out - GTK 4. So I started to look for a Getting Started tutorial for GTK 4, to build... Source: over 4 years ago
  • GTK 4 & JavaScript - how to start?
    BTW, I think the GTK team should really step up their game in terms of how to encourage new people into their ecosystem. Seeing that windows screenshot in the official tutorial makes me think I'm dealing with some old technology. Also, the official gtk.org has two separate tutorials that show very similar applications being built. Source: over 4 years ago

  • Adding Authentication and SSO to a Reflex App
    Reflex is an open-source full-stack web framework written in and for Python that lets you build both frontend UI and backend logic in pure Python, i.e., you donโ€™t need to manually write JavaScript or separately manage a React/Vue frontend and a separate backend. - Source: dev.to / 5 months ago

  • The Best Python Web App Frameworks in 2025
    Streamlit is one such tool that offers a simple, Pythonic approach. However, it suffers from two main weaknesses: the script needs to be re-run after every user interaction, and customizing the look and feel of a Streamlit app is dificult. Shiny for Python is a great alternative for building dashboards and small data-backed apps. Shiny only re-renders code as necessary - not the entire script, and offers more... - Source: dev.to / about 1 year ago
