WebContainers.io features and specs

  • Instant Setup
    WebContainers.io allows developers to instantly spin up a development environment in the browser, reducing setup time and eliminating the need for local configuration.
  • Cross-Platform Compatibility
    By running entirely in the browser, WebContainers.io is inherently cross-platform, offering a consistent development experience regardless of the operating system.
  • Resource Efficiency
    Running the development environment in the browser can reduce the demand on local system resources, allowing for smoother performance on less powerful devices.
  • Collaborative Features
    WebContainers.io supports features that facilitate collaboration, such as sharing environments quickly with peers or collaborators directly through URLs.
  • No Installation Required
    Users do not need to install any traditional software, as all necessary tools and environments are accessible through the web, valuable for environments with installation restrictions.

Possible disadvantages of WebContainers.io

  • Limited Integration
    Some traditional development tool integrations may not yet be available or fully optimized for the WebContainers.io environment, affecting workflow reliance on specific tools.
  • Internet Dependence
    As a web-based solution, it requires an active and reliable internet connection, which can be a limitation for those in areas with poor connectivity.
  • Performance Constraints
    While optimized for browser execution, WebContainers.io may face performance constraints compared to native, local development environments, especially for resource-intensive tasks.
  • Security Concerns
    Running code in the browser could raise security considerations, particularly concerning data privacy and the handling of sensitive information in a cloud-hosted environment.
  • Dependency Constraints
    Certain projects with complex dependency chains or those relying on native modules may encounter challenges in execution within a browser-bound environment.

Emscripten features and specs

  • Cross-platform compatibility
    Emscripten enables developers to compile C and C++ code to WebAssembly or JavaScript, allowing the same codebase to run on multiple platforms, such as browsers and node.js, without needing additional platform-specific adaptations.
  • Leverage existing libraries
    Developers can utilize a vast ecosystem of existing C and C++ libraries by compiling them for the web, saving time and resources required for rewriting or finding alternatives developed in JavaScript.
  • Performance optimization
    Emscripten's compilation to WebAssembly provides near-native performance for web applications, making it suitable for compute-intensive tasks like gaming, simulations, and data processing.
  • Familiar toolchain
    Developers can use familiar tools like CMake and others as part of their Emscripten workflow, making it easier for those with C/C++ backgrounds to adapt and integrate into their web development processes.

Possible disadvantages of Emscripten

  • Steep learning curve
    Developers unfamiliar with C and C++ may find Emscripten challenging to use effectively, as it requires knowledge of these languages and their build systems to create and debug applications.
  • Limitations in browser environments
    Certain features of C/C++ may not translate directly to web environments due to browser sandboxing constraints, leading to potential issues with file I/O, threading, and other system-level operations.
  • Code size
    Compiled WebAssembly and JavaScript code can sometimes be large, potentially affecting load times and performance, especially on lower-end devices with restrictive bandwidth or processing capabilities.
  • Debugging complexity
    Debugging WebAssembly code can be more complex than traditional JavaScript, requiring specialized tooling and techniques to trace and fix issues effectively.

  • Ask HN: Is anyone working on a WASM-based Node engine for the browser?
    There are a number of companies working on solving micro-VM sandboxes, using Firecracker or libkrun. This includes CodeSandbox, E2B and Microsandbox. One of the major use cases is running AI-generated code in a safe environment, with the promise of fast (~2-300 ms) bootup times, pre-built memory snapshots, and the ability hibernate and wake up instances extremely fast. The downside is these solutions still have... - Source: Hacker News / 4 months ago
  • Hacking WKWebview and WebContainers // or WebContainers are we there yet?
    I started writing about the shiny new wasm-y not quite open source tech called webcontainers by stackblitz, but having hacked the crap out them I reckon right now they aren't quite mature enough for production use. - Source: dev.to / 12 months ago
  • Execute JavaScript in a WebAssembly QuickJS Sandbox
    I don't know about using QJS, but if you want to run a bundler in the browser that sounds like the sort of thing that WebContainers[1] were built for. [1]: https://webcontainers.io/. - Source: Hacker News / about 1 year ago
  • Building interactive tutorials with WebContainers
    We'll use some innovative technologies, including WebContainers, CodeMirror, and XTerm, to build this. If you're not familiar with these, don't worry, we'll cover them all during the process. - Source: dev.to / almost 2 years ago
  • API Security Academy dedicated to GraphQL security
    How does it work? There is no backend whatsoever. The API Security Academy leverages WebContainers, a new technology that allows running full-blown node instances directly in the browser. Each WebContainer contains a live GraphQL application, so you'll not only understand why a vulnerability is risky, but also how to exploit it and, most importantly, how to fix it.

  • Ask HN: Qt style "Signals and Slots" based JavaScript UI library?
    The first thing that comes to mind is that Qt now has a WebAssembly port[1] using Emscripten[2], so depending on your use-case, you could possibly just run Qt on the Web platform and avoid the need for a JavaScript framework entirely.

  • Ask HN: Resources for Learning Graphics Programming
    Me and a friend build our own Graphics engines based on https://learnopengl.com I can highly recommend this to everyone who gets started with computer graphics. It is a lot of new information but not the most modern Graphics library, but the information will help you understand the field and pickup any other graphics library quicker.

    One place that Iโ€™ve found some real, open source unit tests to look at for an example is in the emsdk for emscripten: https://emscripten.org. Source: almost 2 years ago
  • Playing with low-level memory in WebAssembly
    I am playing around with Emscipten which wraps around clang to compile C/C++ code in WASM binary and provide some glue-code API to embed WASM binary into JavaScript. Look into MDN Docs and Emscripten SDK to get started. - Source: dev.to / about 2 years ago
