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.

stealjs features and specs

  • Modular Loader
    StealJS is a dynamic module loader that supports ES6, AMD, and CommonJS, offering flexibility in module formats and simplifying the development process.
  • Progressive Loading
    It supports progressive loading, which allows developers to load JavaScript dependencies only as needed, improving application performance and reducing initial load times.
  • Compatibility
    StealJS is compatible with various environments, including Node.js and web browsers, facilitating seamless development and deployment.
  • Plugin System
    Its extensible plugin system allows developers to customize the build process and integrate with other tools or libraries easily.
  • Live Reload
    StealJS provides live reload functionality, enabling developers to see changes instantly without manually refreshing the page, hence improving the development workflow.

Possible disadvantages of stealjs

  • Learning Curve
    Developers familiar with more traditional build tools might face a steep learning curve initially when adopting StealJS.
  • Community and Support
    StealJS has a smaller community compared to more popular bundlers like Webpack, which can result in less available support and resources.
  • Configuration Complexity
    Though powerful, its configuration can become complex for larger projects and may require additional effort to manage efficiently.
  • Performance Overhead
    Dynamic loading can introduce some runtime performance overhead compared to static bundling, potentially affecting execution speed.
  • Ecosystem
    While StealJS integrates with many tools, it may not have the same breadth of plugin ecosystem that some larger projects offer, potentially requiring manual integrations.

  • 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 / 8 months 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 / about 2 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 / almost 4 years ago
