freeCodeCamp Challenge Guide: Serve Static Assets

Serve Static Assets

Problem Explanation

Serving static webpages and assets is fairly simple with express. This could be useful for building your own portfolio website or blog, single-page web applications etc.

To serve static assets from the public folder you can use the express.static() method as the middleware. This method takes the endpoint and the absolute path to the directory containing the static assets as arguments and exposes the files in that folder at the given endpoint. By default, if the endpoint is not passed to the method, the folder is exposed at the root endpoint i.e. / for the application.

The __dirname variable is a string containing the absolute path to the root of your project which has to be concatenated with the folder containing the assets.

Add the following line to your file above all defined routes to achieve the desired result:

// Normal usage
app.use(express.static(__dirname + "/public"));

// Assets at the /assets route
app.use("/assets", express.static(__dirname + "/public"));
