# --description--
|

|

An HTML server usually has one or more directories that are accessible by the user. You can place there the static assets needed by your application (stylesheets, scripts, images).
|
|||
|
|
|
|||
|
|
In Express, you can put in place this functionality using the middleware `express.static(path)`, where the `path` parameter is the absolute path of the folder containing the assets.
|
|||
|
|
|
|||
|
|
If you don’t know what middleware is... don’t worry, we will discuss in detail later. Basically, middleware are functions that intercept route handlers, adding some kind of information. A middleware needs to be mounted using the method `app.use(path, middlewareFunction)`. The first `path` argument is optional. If you don’t pass it, the middleware will be executed for all requests.
|
|||
|
|
|
|||
|
|
# --instructions--
|
|||
|
|
|
|||
|
|
Mount the `express.static()` middleware to the path `/public` with `app.use()`. The absolute path to the assets folder is `__dirname + /public`.
|
|||
|
|
|
|||
|
|
Now your app should be able to serve a CSS stylesheet. Note that the `/public/style.css` file is referenced in the `/views/index.html` in the project boilerplate. Your front-page should look a little better now!
|
|||
|
|
|
|||
|
|
# --hints--
|
|||
|
|
|
|||
|
|
Your app should serve asset files from the `/public` directory to the `/public` path
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
(getUserInput) =>
|
|||
|
|
$.get(getUserInput('url') + '/public/style.css').then(
|
|||
|
|
(data) => {
|
|||
|
|
assert.match(
|
|||
|
|
data,
|
|||
|
|
/body\s*\{[^\}]*\}/,
|
|||
|
|
'Your app does not serve static assets'
|
|||
|
|
);
|
|||
|
|
},
|
|||
|
|
(xhr) => {
|
|||
|
|
throw new Error(xhr.responseText);
|
|||
|
|
}
|
|||
|
|
);
|
|||
|
|
```
|
|||
|
|
