Angular2 how to set app root path independently from html base url


I'm building an angular2 application/widget that will be embedded into TYPO3 as a plugin that can be inserted on any content page. This means it could end up at different root paths e.g.:

/page1/app
/page/subpage/subpage/whatever

The global base url (base href=..) is already set by TYPO3 and can't be changed. How can I give angular some kind of root prefix so that it can build up its routes correctly?

I'm using the new router as documented here: https://angular.io/docs/ts/latest/guide/router.html


Solution

  • Actually there is a solution in the angular docs but it's pretty hard to find. It's possible to set the base url in angular without using a <base> tag.
    So you just have to set the base url to a global JavaScript variable using fluid and then provide it to angular in the app module.

    Fluid:

    <script>
       var app_base_url = '<f:uri.page pageUid="{currentPageUid}" />';
    </script>
    

    Angular:

    declare var app_base_url;
    
    import {Component, NgModule} from '@angular/core';
    import {APP_BASE_HREF} from '@angular/common';
    @NgModule({
      providers: [{provide: APP_BASE_HREF, useValue:app_base_url}]
    })
    class AppModule {}
