Purpose

This repo is a test to see whether angular-auth-oidc-client can work with server-side rendering (SSR). There is active discussion about how to make this happen, so I'm hoping to use this as a baseline for testing.

Overview

The basic SSR template is from Mark Piezak's JavaScript Services repo, and enhanced it with a few extra things:

• a storage service that is injected with different implementations for client-side rendering and server-side rendering (see storage-config.ts for details)
  • the client-side implementation uses bouzuya's cookie-storage so that tokens end up getting saved as cookies that get passed up to the server.
  • the server-side implementation uses memorystorage and automatically populates itself based on values from the cookies.
• A basic configuration of angular-auth-oidc-client - see storage-config.ts for details.

Setup

To get this repo running on your machine, do the following:

1. Make sure you have the latest versions of dotnet core (currently 2.0-preview2) and node installed
2. Clone the repo and run dotnet restore and npm install
3. For development goodness, set the environment to Development:
   • Mac: export ASPNETCORE_ENVIRONMENT=Development
   • Windows: set ASPNETCORE_ENVIRONMENT=Development
4. Start the application by running dotnet watch run
5. Try it out by visiting http://localhost:5000 in the browser.

Current Results

Currently, server-side rendering will not work because it looks like some parts of angular-auth-oidc-client are making calls to window, which isn't available on the server. You'll see this stack trace:

An unhandled exception occurred while processing the request.

Exception: Call to Node module failed with error: ReferenceError: window is not defined
at OidcSecuritySilentRenew.initRenew (C:\Users\ansteg\Projects\debug-test\ClientApp\dist\main-server.js:18288:45)
at OidcSecurityService.setupModule (C:\Users\ansteg\Projects\debug-test\ClientApp\dist\main-server.js:18446:42)
at Object.configAuth (C:\Users\ansteg\Projects\debug-test\ClientApp\dist\main-server.js:20725:26)
at new AppModule (C:\Users\ansteg\Projects\debug-test\ClientApp\dist\main-server.js:11778:23)

It appears to fail due to these lines in oidc.security.silent-renew.ts. However, it is likely that this is just the first failure hit and that there are others--because a quick search of angular-auth-oidc-client reveals multiple references to window.

You can turn off server side rendering for testing purposes by changing these lines in Index.cshtml:

<app asp-prerender-module="ClientApp/dist/main-server" asp-prerender-data="new { Cookies = ViewContext.HttpContext.Request.Cookies }">Loading...</app>

to

<app>Loading...</app>
