Professionally I use React and Vue. Personally I have moved to Svelte for side projects and personal ideas.
Absolutely, Svelte is still very young and needs more polishing. Those of us who have seen the overall benefits to utilizing Svelte it in its current state, envision a very bright future for the Svelte team. That's why some of us have taken it upon ourselves to help Svelte and its current dev team gain traction and more interest in the project. It needs the funding to grow. Then you'll see versions of Svelte that have a CLI to include the things you need. It takes time.
React was a mess when it came out in 2015, it is still evolving, it has recently shown favour with functional programming thus introducing Hooks and trying to get devs to use functions over classes. Angular went through a complete re-write to its current form. Vue came in with a very different support system and its ecosystem quickly evolved. The CLI is brilliant. It took a few years to get there. They all have special traits in terms of using props, templating and reactivity.
Lastly, for the demo I placed with this article. I would never consider React, Vue, Angular. While everyone wants to live at the bleeding edge of tech, they some times forget there are many of us who work on significantly smaller projects and don't require the complexity of the Big Three but still want the ability to scale.
Hey, I hear you. I'd love for Svelte to get more attention and work. In fact, one of my side projects this year (admittedly it got sidelined before I even started) was to implement the svelte compiler in Rust. So I really believe that Svelte has some nice value adds as a toolset for web development. That said, my points were:
In the future, however, I do see a place for a svelte-like compiler that is more flexible and can handle importing/exporting multiple languages.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
