Meziantou.AspNetCore.BundleTagHelpers

The code of this TagHelper has moved to the BundlerMinifier repository: https://github.com/madskristensen/BundlerMinifier

When you use the Visual Studio extension BundleMinifier (download), you have to declare the bundles in the bundleconfig.json file (input files, output file and minification options). The idea of this project is to generate the script and link tags by using the list of bundles define in the bundleconfig.json file. So, instead of writing a code similar to (from the ASP.NET Core template):

<environment names="Development">
    <link rel="stylesheet" href="~/css/site1.css" />
    <link rel="stylesheet" href="~/css/site2.css" />
    <link rel="stylesheet" href="~/css/site3.css" />
</environment>
<environment names="Staging,Production">
    <link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true" />
</environment>

You only write this:

<bundle name="wwwroot/css/site.min.css" />

• In production, it uses the minified file and appends the version in the query string (same behavior as asp-append-version).
• In development, it uses all input files and does not append version.

Note: This goal of this project is not to minify files, but only to generate the script and link tags. The BundleMinifier extension does generate min files.

The code in the directory BundlerMinifier comes from the BundlerMinifier repo, so the file is interpretted as the extension does.

How to use

• Install NuGet package Meziantou.AspNetCore.BundleTagHelpers
• Register the tag helpers:

@addTagHelper *, Meziantou.AspNetCore.BundleTagHelpers

• Use the tag helper

<bundle name="wwwroot/js/site.min.js" />
<bundle name="wwwroot/css/site.min.css" />

• (optional) Edit the Startup.cs file:

//using Meziantou.AspNetCore.BundleTagHelpers;

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();
    services.AddBundles(options =>
    {
        options.UseMinifiedFiles = false;
        options.AppendVersion = false;
    });
}
