StackBlitz features and specs

  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.

Possible disadvantages of StackBlitz

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.

  1. Has almost everything I need

    I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

    ๐Ÿ Competitors: replit
    ๐Ÿ‘ Pros:    Easy to get started and operate|Fast|Supports common extensions|Works with most npm packages
    ๐Ÿ‘Ž Cons:    Still not as good as local development|Can be hard to debug|Build times can be slower than local

All applications created on StackBlitz also get deployed automatically on their servers! So, this Angular toy app I just created is hosted automatically on https://angular-yvyi2j.stackblitz.io/. Most likely, the URL is still working (will load slowly, though, as youโ€™d expect when hosted for free)!

  • RS-X: Framework-agnostic reactive state and expressions for JavaScript/TS
    Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 7 months ago
  • Show HN: I combine Htmx, LiveView and SolidJS for interactive server components
    I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 9 months ago

    I like htmx, LiveView, React and Solid. They are great at different points, and this is a prototype trying to combine them. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is added to achieve efficient DOM updates + minimal payload size.... - Source: Hacker News / 9 months ago

  • Building docling-server: a one-command document API for our AI pipeline
    If you have not seen docling yet, it is IBM's document processing library. PDF, DOCX, PPTX, scanned images, tables, the whole lot โ€” out comes structured output. Very good at its job. The problem is not docling. The problem is everything around it. - Source: dev.to / 4 months ago
  • The Curse of Context Window
    OCR was the obvious option and with so many opensource libraries available, we were spoilt for choices. I Wanted to use Docling as my prior experience with it has been good so Far (I shall write a separate blog on those use-cases) but we were constrained by the infra. - Source: dev.to / 6 months ago
