What is workflow in Yeoman to work with Sass files? - sass

Question

I try to use yeoman but I don't know how to use my own sass files with it.
With
grunt server
Sass files are watched and compiled into
.tmp/styles/
But there is no reference to the compiled stylesheet, except <link rel="stylesheet" href="styles/main.css">
So, what is the recommended way to use the compiled sass files in index.html during development?
E.g. grunt server, if I change my style app/styles/my.sass into .tmp/styles/my.css, this is overwritten and it is outside the server (localhost:9000). Therefore, it is impossible to link it in index.html.
With grunt build is everything within main.css include my.sass but during the development I don't know how to use my own sass files in index.html.
Can you give me some simple example?
It is default yeoman installation. I did this:
yo angular test
I add app/styles/style.sass
grunt server this compile style.sass into .tmp/styles/style.css
now I don't know how to include style.css it in html
(sorry may be this is a stupid question but I am new in yeoman and grunt also)
This is Gruntfile.js from yeoman:

Answer 1

What you are looking for is documented on: https://github.com/yeoman/grunt-usemin
Simply wrap your css imports in a comment block similarly to the way it's done with the javascript files
<!-- build:css styles/main.css -->
<link rel="stylesheet" href="styles/base.css">
<link rel="stylesheet" href="styles/modules.css">
<link rel="stylesheet" href="styles/layout.css">
<!-- endbuild -->
make sure your generator is up to date and your grunt tasks are all set. The one doing the magic is 'useminPrepare'

Answer 2

The actual magic for development is happening in
mountFolder(connect, '.tmp'),
for the connect-livereload middleware for grunt-contrib-watch.
This makes the local server also serve the contents of the .tmp folder, which is why you can reference styles/main.css and get .tmp/styles/main.css in return.
useminPrepare is usually never called in the server task.

Answer 3

You just include it like
<link rel="stylesheet" href="styles/style.css">
Yeoman/grunt will know when running the server that it should grab the sass file from the temp folder.
