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.

  • 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 / about 1 year 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 2 years ago
