Hands-On RESTful Web Services with Go - Second Edition

Building a simple static file server in minutes

Sometimes, an API can serve files. The other application of httprouter, apart from routing, is building an efficient file server. It means that we can build a content delivery platform of our own. Some clients need static files from the server. Traditionally, we use Apache2 or Nginx for that purpose. If one has to create something similar purely in Go, they can leverage httprouter.

/static/*

The plan is to use http package's Dir method to load the filesystem, and pass filesystem handler it returns to httprouter. We can use the ServeFiles function of the httprouter ...
