AspNet.AssetManager

Build status codecov NuGet Version

Minimal asset manager for ASP.NET Core that reads your frontend tool's manifest (Vite or key-value) and renders the correct tags/paths in development and production.

  • Simple TagHelpers: <link-bundle /> and <script-bundle />
  • Automatic bundle name inference from the active view.
  • Optional per-view overrides via ViewData["Bundle"]
  • Works with a dev server (e.g., Vite, Webpack) in development, and static files in production.

See the template repository, for usage examples: AspNet.Frontends

Install

dotnet add package AspNet.AssetManager

Quick start

Register services in Program.cs:

using AspNet.AssetManager;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddAssetManager(builder.Configuration, builder.Environment);

Register tag helpers in Views/_ViewImports.cshtml:

@addTagHelper *, AspNet.AssetManager

Use in Views/Shared/_Layout.cshtml:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>@ViewData["Title"] - AspNet.AssetManager</title>
  <link-bundle fallback="Layout" />
</head>
<body>
  @RenderBody()
  <script-bundle defer fallback="Layout" />
  @await RenderSectionAsync("Scripts", required: false)
</body>
</html>

How bundle names are chosen

  • By default, the bundle name is inferred from the active view.
    • Example: /Views/Home/Index.cshtml → Views_Home_Index
  • You can override it using ViewData["Bundle"]. Two forms are supported:
    • A plain name e.g., Home_Index
    • A view-like path starting with a slash e.g., /Views/Home/Index, which will be converted to the bundle name: Views_Home_Index

Development vs. production behavior

  • Development:
    • Manifest is fetched from the dev server. If the server is not running, you will see: Development server not started!.
    • Tag helpers add crossorigin="anonymous" automatically; with "ManifestType": "Vite", script tags also use type="module".
    • Paths point to the dev server: PublicDevServer + PublicPath.
  • Production:
    • Manifest is read from disk: wwwroot + PublicPath + ManifestFile.
    • Paths are relative to PublicPath, served by UseStaticFiles().

Configuration (appsettings.json)

{
  "AssetManager": {
    "PublicDevServer": "http://localhost:5173",
    "InternalDevServer": "http://localhost:5173",
    "PublicPath": "/dist/",
    "ManifestFile": "assets-manifest.json",
    "ManifestType": "KeyValue"
  }
}
  • PublicDevServer: required. The browser-facing URL of your dev server (e.g., Vite).
  • InternalDevServer: optional. If your app runs behind Docker/WSL/etc., point this to where the server is reachable from the app process. Falls back to PublicDevServer if omitted.
  • PublicPath: the public base path for built assets. In production this is under wwwroot; in development it is appended to the dev server URL. Default is /dist/.
  • ManifestFile: the filename of your manifest. Default is assets-manifest.json.
  • ManifestType: KeyValue or Vite. Default is KeyValue which matches the format used by webpack-assets-manifest.

Manual rendering

If you prefer code-based rendering or need more control, inject IAssetService.

@using AspNet.AssetManager
  
@inject IAssetService AssetService

@{
    var bundle = ViewData.GetBundleName() ?? Html.GetBundleName();
}

/* Base paths */
@AssetService.WebPath

/* Resolve paths */
@await AssetService.GetBundlePathAsync("SomeBundle.js")
@await AssetService.GetBundlePathAsync("SomeBundle", FileType.JS)

/* Script tags */
@await AssetService.GetScriptTagAsync("SomeBundle")
@await AssetService.GetScriptTagAsync("SomeBundle", ScriptLoad.Async)
@await AssetService.GetScriptTagAsync("SomeBundle", "FallbackBundle", ScriptLoad.Async)

/* Link tags */
@await AssetService.GetLinkTagAsync("SomeBundle")

/* Style tags */
@await AssetService.GetStyleTagAsync("SomeBundle")
