CodePush features and specs

  • Instant Updates
    CodePush allows developers to deploy updates to their apps immediately, without requiring users to download a new version from the app store, resulting in faster bug fixes and feature rollouts.
  • Easy Integration
    CodePush integrates seamlessly with existing mobile app infrastructures and supports popular frameworks like React Native, Cordova, and Ionic, making it easy for developers to add over-the-air update capabilities.
  • No Store Re-approval
    Updates pushed through CodePush do not require app store re-approval, which can save time and help maintain app stability by quickly addressing issues that donโ€™t involve major codebase changes.
  • Reduced Update Fatigue
    Users benefit from a more streamlined experience as they receive constant, incremental improvements without being repeatedly prompted to download and install large app versions.

Possible disadvantages of CodePush

  • Limited to JavaScript Code and Assets
    CodePush can only update JavaScript code and assets, not native code. This limits its use to web-based code changes, so any changes to native modules still require a full app store release.
  • Potential for Misalignment
    If not carefully managed, there's potential for clients to run different versions of code, leading to discrepancies in app behavior if the JavaScript logic doesn't align with the native code expectations.
  • User Consent Required
    Automatic updates require user consent, and some users may opt-out of receiving updates this way, which can result in fragmentation or running outdated app versions.
  • Compliance Risks
    Modifying app logic over-the-air without going through app stores can potentially violate platform compliance guidelines or terms of service, especially if critical updates circumvent necessary oversight.

SystemJS features and specs

  • Universal Module Loader
    SystemJS supports loading modules in various formats, such as AMD, CommonJS, and ES modules, providing versatility in deploying applications with different module specifications.
  • Dynamic Imports
    SystemJS enables dynamic loading of modules, which allows for lazy loading of parts of applications. This can lead to performance improvements by asynchronously loading only the necessary parts of your application.
  • Compatibility
    SystemJS provides compatibility across different JavaScript environments, making it a suitable choice for projects that require running code on both browsers and Node.js.
  • Extensibility
    With a plugin system that lets developers extend its capabilities, SystemJS can be customized to handle specific loading scenarios or integrate more seamlessly with different build processes or frameworks.

Possible disadvantages of SystemJS

  • Complexity
    The flexibility and extensive feature set of SystemJS can introduce complexity in configurations and require a learning curve for new developers, particularly with its extensive plugin ecosystem.
  • Performance Overhead
    Because SystemJS is a global loader, it introduces additional runtime overhead compared to using native ES modules or simpler bundling solutions, which might impact performance.
  • Reduced Relevance with ES Modules
    With the native support for ES modules in modern browsers, the need for SystemJS has decreased, as developers can often achieve the desired module functionality with built-in browser capabilities.
  • Complex Debugging
    SystemJS's dynamic loading and transformations can make debugging more challenging, as developers may struggle with source mapping or understanding how modules are resolved.

  • A Deep Look at the Flutter SDK: What's Actually Under the Hood
    This creates Flutter's fundamental limitation: no code push capability. React Native developers can update JavaScript bundles at runtime through services like Microsoft's CodePush. Flutter's compiled Dart code is static machine code. There's no runtime interpreter in release builds. Once you publish an app, fixing bugs requires a full app store submission. That's typically 1-7 days for Apple review and hours to a... - Source: dev.to / 7 months ago
  • Searching: react native ota update self hosted
    In my opinion it doesn't make any sense you can use https://microsoft.github.io/code-push/ which is free. I use this for my apps android/ios and works fine.. I hope it helps. Source: about 3 years ago
  • Hot fixes on Chrome Extension live
    I come from smartphone app development and now moving to chrome extensions I miss something called CodePush which would push Javascript changes live to app store, but not native code so we could hot fix critical stuff without waiting for store reviews... Source: over 3 years ago
  • All you should know about Flutter development
    One feature I feel holding Flutter back compared to ReactNative and other options is Code Push. I really enjoy writing Flutter apps but the ability to push updates and bypass store reviews has been extremely valuable for multiple companies I've built apps for. https://microsoft.github.io/code-push/. - Source: Hacker News / over 4 years ago
  • Ask HN: Robust and affordable alternatives to Google Play for app distribution?
    Couldn't you just add the adults as testers to the Google Play app, avoiding oversight? The problem with breaking off from Google Play is you lose the ability to send push notifications. You could look at Code Push [0] for seamless updates. TBH its not the easiest to integrate with. [0] - https://microsoft.github.io/code-push/. - Source: Hacker News / over 4 years ago

  • Integrate Web Component/MFE with plain static HTML
    Using the SystemJS library, we can seamlessly integrate a web component or MFE, or even import any module at runtime. - Source: dev.to / almost 2 years ago
  • Rails upgrade to angular 2
    I would like to upgrade my existing Rails and Angular 1.x application. I'm following the ng-upgrade documentation and seeing that there are many dependencies including systemjs, typescript, tsd and a few other javascript libraries. Ideally there would be a angular-2 gem that would have all the dependencies but I'm not able to find that. Next I looked for gem's for each dependency but there isn't one for tsd.

  • Modern SPAs without bundlers, CDNs, or Node.js
    There's also https://github.com/systemjs/systemjs if you want more of a ponyfill approach. FWIW bundlers also don't use the browser's functionality to load modules... - Source: Hacker News / over 3 years ago
  • JS Modules
    A module loader interprets and loads a module written in a certain module format at runtime. Popular examples are RequireJS and SystemJS. - Source: dev.to / about 5 years ago
