Great article, thanks Michael!

I've written an article inspired by yours, explaining how to integrate Tailwind in a Nrwl NX project and with Storybook as well: medium.com/@dSebastien/adding-tail...

I was trying to follow this guide, but I get an error with the webpack config file saying: `An unhandled exception occurred: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.

  • configuration has an unknown property 'call$1$0'. These properties are valid (...). Any ideas - copy pasted the extra-webpack.config.js` file, using Angular 10

Fine Job, Michael!

The genius of this post is the section: "Separating Tailwind CSS from the rest".

For those of you who have struggled with the other 4 or 5 other Angular/Tailwind examples out there - save your yourself the headache of installing additional postcss loaders to accommodate your custom or nested scss, or file/image loaders to find relative paths like, url(my.png), and the same with font references. Phew!

It just makes so much sense to isolate Tailwind and target it only with a custom webpack config.

Again, Kudos!

This is a very helpful post. Thanks a lot Michael.

There's a bit of a typo though, but it's no biggie. On the section of modifying the serve section,

ng config projects..architect.serve.builder @angular-devkit/build-angular:dev-server

it should be,
ng config projects..architect.serve.builder @angular-builders/custom-webpack:dev-server

Actually this works exactly like described in the post. The styles.(s)css where material is added is not touched by this approach.
So, after you completed the steps above do

ng add @angular/material

answer a few questions and you're done.

Unfortunately, ng add doesn't work because we have changed the builder:

Your project is not using the default builders for "build". The Angular Material schematics cannot add a theme to the workspace configuration if the builder has been changed.

You can add the styles in yourself:

For example, under architect, build, add indigo-pink.css to your styles array:
"styles": [
"src/styles.css",
"src/tailwind.scss",
"node_modules/@angular/material/prebuilt-themes/indigo-pink.css"
],

Hi Michael,
I've seen new angular 9 apps using Tailwindcss without the need to touch webpack, or to install @angular-builders/custom-webpack, how do they work ?

Oh, sorry, I just got that this tutorial was about triggering simultaneously Tailwind build at "ng serve" command execution.
