# css-minify

### a css-compression tool

## Install:

### Global:

`yarn global add css-minify`

or

`npm install css-minify -g`

### Local

`yarn add css-minify`

or

`npm install css-minify`

## Usage:

### CLI

If you want to deal with a single css file,you can do it like this:

`css-minify -f filename`

or 

`css-minify --file filename`

If no file / dir are specified, check if STDIN has data, and if so, run the minifier and print on STDOUT

```
> echo "body { color: #ff0000; }" | node bin/css-minify.js
body{color:red}
```

**Warning:**

Be sure that filename must be ended with ".css"

However,if you have too many css files to deal with,you can do it like this:

 `css-minify -d sourcedir`

or 

`css-minify --dir sourcedir`

And then, if you want to specify output directory, use `-o` or `output` like below(introduced in 1.1.0):

`css-minify -d sourcedir -o distdir`

or

`css-minify --dir sourcedir --output distdir`

**Tips:**

All css source files are in the sourcedir directory

At last, you will see the minified css file, which is ended with `.min.css` in directory specified by `-o` or `--output`, which is `css-dist` by default.
