Running Angular2 In Subdirectory

问题

I have an app which runs fine under localhost.

I tried to put it out on an IIS server today as a child application. So the new path would be localhost/SubDir.

System.js pukes everywhere trying to load modules now. I set the basePath and played with the path/map config variables for a few hours but couldn't land on the magic settings.

Does anyone have ideas what I'd want to tweak, or anything that would help with debugging?

          baseURL: '/MedicheckAngular/',
          paths: {

      System.import('app/app');

And the App entry point

import {HTTP_PROVIDERS} from 'angular2/http';
import {bootstrap, bind, provide} from 'angular2/angular2';
import {RouteConfig, RouteParams, ROUTER_DIRECTIVES, APP_BASE_HREF, ROUTER_BINDINGS, LocationStrategy, PathLocationStrategy, HashLocationStrategy} from 'angular2/router';

import {AppLayout} from './components/app-layout/app-layout';


bootstrap(AppLayout, [
    ROUTER_BINDINGS,
    HTTP_PROVIDERS,
    provide(APP_BASE_HREF, {useValue:'/'}),
    provide(LocationStrategy, { useClass: HashLocationStrategy })
]);

App Folder Structure

回答1:

To host in a sub directory with apache, you can just do this:

Build command similar to this: ng build --base-href /myapp/

.htaccess file would look like this

RewriteEngine On
RewriteBase /myapp/
Options +FollowSymLinks

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.html [L,QSA]

回答2:

When you're deploying to a non-root path within a domain, you'll need to manually update the following:

<base href="/">

to:

<base href="/MedicheckAngular/">

in your dist/index.html, or make changes as follows:

Change baseUrl: '/MedicheckAngular/' in webpack.common.js.
Add /MedicheckAngular/ to the links in index.html.

回答3:

try to remove the baseURL from the config of systemjs and add the <base href="MedicheckAngular/" /> to your head part in the HTML DOM.

I had my Angular2 App in the subfolders "modules/angular" from the root. `

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Hallo</title>
    <base href="modules/angular/">
</head>
<body>
   <myapp>loading...</myapp>

   <script src="/modules/angular/node_modules/es6-shim/es6-shim.min.js"></script>
   <script src="/modules/angular/node_modules/systemjs/dist/system-polyfills.js"></script>
   <script src="/modules/angular/node_modules/angular2/es6/dev/src/testing/shims_for_IE.js"></script>
   <script src="/modules/angular/node_modules/angular2/bundles/angular2-polyfills.js">   </script>
   <script src="/modules/angular/node_modules/systemjs/dist/system.src.js"></script>
   <script src="/modules/angular/node_modules/rxjs/bundles/Rx.js"></script>
   <script src="/modules/angular/node_modules/angular2/bundles/angular2.dev.js"></script>

    <script>
    System.config({
        packages: {
            "apps": {
                format: 'register',
                defaultExtension: 'js'
            }
        }
    });
    System.import('apps/main').then(null, console.error.bind(console));
    </script>
</body>
</html>`

I struggled for a while to do something similar. I have a wordpress running on an apache server. For SEO reason we wanted the angular app to be hosted on a sub-folder, in the way phpmyadmin is hosted.

What I did is to create a subfolder in /apps/my-app-hosting-folder
Create an alias to this folder : /my-alias => /apps/my-app-hosting-folder
Change the base ref from base href="/" to base href=""

This worked.

The other things I tried didn't give me satisfaction for the following reasons :

set base ref to the alias : I would have needed to manually fix links through the app and with some weird configuration I ended up with something like www.exemple.com/my-alias/my-alias/index; something went wrong between the alias and the base ref.
leaving "/" broked some inner link by adding some weird "/" so I had broken url like : www.exemple.com/my-alias/node//blabla; I think it tries to work with the root folder of the server.

Hope it will help the futur readers.

回答5:

I put a ~ on the "base href"

<!-- Angular2 Code -->
<base href="~/">
<link rel="stylesheet" href="styles.css">
<!-- Polyfill(s) for older browsers -->
<script src="~/node_modules/core-js/client/shim.min.js"></script>
<script src="~/node_modules/zone.js/dist/zone.js"></script>
<script src="~/node_modules/reflect-metadata/Reflect.js"></script>
<script src="~/node_modules/systemjs/dist/system.src.js"></script>
<script src="~/systemjs.config.js"></script>
<script>
  System.import('app').catch(function(err){ console.error(err); });
</script>
<!-- Angular2 Code -->

回答6:

Here's what worked for us:

Make the base ref point to the subdirectory containing the angular project. This will ensure that all the node_module dependencies are found, etc.
Configure the PathLocationStrategy with a different APP_BASE_HREF so that html5 mode still works for the actual angular app.

bootstrap(AppComponent, [..... bind(APP_BASE_HREF).toValue("/yardmap/planning")

ref: https://angular.io/docs/ts/latest/guide/router.html

回答7:

If you don't know the subdirectory upfront, you can use a dot as path at /src/index.html file like this:

<base href=".">

Then just build with command: ng build --prod. Then get the output from inside of /dist directory as usual.

Now your app can be placed in any web dir or even works from the filesystem (if no restricted API is used).

回答8:

I think that you've miss a subfolder.

What you've put in your 'index.html' file, means that files to load are located in your home directory.

/home/<your_directory>/[...] <- You try to load files from there.

I think that your server structure is more like that.

/home/<your_directory>/***<app_folder>***/[...] <- I think your files are located here.

If you have a console access to your server , try to locate your application folder, with pwd for example and then replace in your 'index.html' '~/' in your src tags with the returned path and it will work as expected.

回答9:

The full configuration for running Angular app in subdirectory.

Assuming "ng-app/" as the alias path. For example http://www.example.com/ng-app/

Apache config

Alias /ng-app  /<Directory path of index.html>/
Alias /assets /<Directory path of index.html>/assets/
<Directory /<Directory path of index.html>>
    DirectoryIndex index.html

    Require all granted
    RewriteEngine on
    RewriteCond %{REQUEST_FILENAME} -s [OR]
    RewriteCond %{REQUEST_FILENAME} -l [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^.*$ - [NC,L]
    RewriteRule ^(.*) /index.html [NC,L]
</Directory>

Set baseUrl in index.html

<base href="/ng-app/">

Suppose the angular-app doesn't work on reload, Add the LocationStrategy provider in app.module.ts

import {LocationStrategy, HashLocationStrategy} from '@angular/common';
@NgModule({
    providers: [
        {provide: LocationStrategy, useClass: HashLocationStrategy}
    ]
});

回答10:

Not need to do more , just change one line after the build project in index.html

<base href="/">

<base href="/sub directory_name/">
