🔥 A new version of this template has been released for .NET 6 Preview 3+, it support blazor + tailwindcss with hot reload and css isolation https://github.com/barahonajm/blazor-tailwindcss-template
In this guide we are going to fully integrate TailwindCSS with Blazor and the dotnet build system
Summary:
We are going to use Webpack to get TailwindCSS and bundle our CSS's files into one so we can import it into our
index.html
or_hosts.cshtml
file.We are going to create a Targets file to let the
dotnet build
system deal with the npm and webpack tasks so we can simple run dotnet build to have everything ready to use.
Requisites:
- Nodejs and npm installed
- Have a Blazor project created
Adding TailwindCSS and necessary configurations
First, we are going to create a new folder in our Blazor project called StaticAssets
which will contain the following files:
📁StaticAssets
📁css
📝 file1.css
📝 file2.css
📝 main.css
📝 package.json
📝 tailwind.config.js
📝 postcss.config.js
📝 webpack.config.js
📝 StaticAssets.targets
main.css
This file will be the entry point in our webpack configuration so it must import all your other css files which will likely contains your own rules composed on terms of TailwindCSS.
Here an example of what could be inside your file1.css
package.json
Contains our dependencies
and the scripts
that will be run by the dotnet build system.
The package.json file includes the following dependencies to helps us obtain a bundled css from webpack and avoid generation of empty js files
"mini-css-extract-plugin": "^0.9.0",
"webpack-fix-style-only-entries": "^0.5.1"
postcss.config.js
Since tailwind is a postcss plugin we will need a postcss config file with the following contet:
For more information about TailwindCSS and PostCSS refer their official docs.
webpack.config.js
Contains the minimal configuration to take our main.css
compile it and then export into our wwwroot/css
folder so we can use the resulted file into our index.html
or _Hosts.csthtml
StaticAssets.targets
Finally, this file will contain all the necessary configurations to integrate everything with dotnet build system, specifically:
Adds support to run
npm install
andwebpack
when you rundotnet build
so you don't need to run it manuallyAdds support for incremental build, so the above commands will only be executed if there are changes in any of the files inside
StaticAssets
folder
Adding everything into your Blazor project
Once the above files are created, we need to do a few more steps to fully integrate it into our Blazor project.
Modify your .csproj file
Your .csproj
must contain the new targets
file we have created, to do that we only need to import it at the end:
At this point you can already invoke dotnet build
and you will notice that the npm install and webpack are executed too, this will generate a file called main.css
inside your wwwroot/css
folder.
Import main.css file into your index.html
Now that we have our main.css
which contains our own rules as well as all tailwind rules, we can import it into our index.html
which is in wwwroot
folder.
Conclusion
With these steps you are going to be able to use the TailwindCSS utilities into .razor files without any problem, if want to create acss files that are composed in term of TailwindCSS just make sure to put it into StaticAssets folder and import into your main.css file.

I've been looking for this as well, I'd love to be able to use tailwind/postcss from within isolated blazor component css files.
This is done i the new version of the template, github.com/juancient/blazor-tailwi...
Great effort, thank you!
