# CSS Modules: Extract Imports
[](https://travis-ci.org/css-modules/postcss-modules-extract-imports)
Transforms:
```css
:local(.continueButton) {
composes: button from "library/button.css";
color: green;
}
```
into:
```css
:import("library/button.css") {
button: __tmp_487387465fczSDGHSABb;
}
:local(.continueButton) {
composes: __tmp_487387465fczSDGHSABb;
color: green;
}
```
## Specification
- Only a certain whitelist of properties are inspected. Currently, that whitelist is `['composes']` alone.
- An extend-import has the following format:
```
composes: className [... className] from "path/to/file.css", className [... className], className [... className] from global;
```
## Options
- `failOnWrongOrder` `bool` generates exception for unpredictable imports order.
```css
.aa {
composes: b from "./b.css";
composes: c from "./c.css";
}
.bb {
/* "b.css" should be before "c.css" in this case */
composes: c from "./c.css";
composes: b from "./b.css";
}
```
## Building
```
npm install
npm test
```
