Loading modules from different server at runtime

问题:

Is it somehow possible to load different modules in my angular 2 app runtime, from different servers and if so, how can I achieve this?

I would like to have my app load different components from the overall application from isolated servers (A, B, C), so they can be taken down and updated independently from the main app and any components which are included in A, B or C won't be loaded. The 3 modules shown on the bottom would have the Components, but the Main App would declare in it's HTML where it should load the component.

UPDATE

Lazy loading through routes is not what I'm looking for, the 3 modules should be completely independent modules which have their own repository, project, hosting, enz.

A little late, but you can use the lazy-loading mechanism in routes to do exactly what you want.

This article states on how to load a webpack module from another source: Solution: load independently compiled Webpack 2 bundles dynamically

In the routes you define a callback in the loadchildren section:

const appRoutes: Routes = [
    {path: '', component: MainComponent},
    {path: 'modulea', loadchildren: loadModuleA}
]

the loadModuleA method would look like:

export function loadModuleA() {

    return new Promise((resolve, reject) => {

        // the method from the article
        loadPlugin('path/to/server/of/moduleA', (exports) => {
            // The Submodule must export ModuleA
            resolve(exports.ModuleA);
        });

    });

}
