Static files

Serving static files

Until now, we have been using our server to send back data such as strings or json. However, we can serve whole files such as pictures or documents, too!

Public directory

Although you can put the files you'd like to serve anywhere, it's convention to put them in the resources directory under a folder called public

src
└── main
    └── resources
        └── public
            ├── logs
            │   └── hello.txt
            └── logo.png

Using config.staticFiles.add()

We instruct our javalin app to serve files from public using config.staticFiles.add().

var app = Javalin.create(config -> {
  // set up static files
  config.staticFiles.add("/public", Location.CLASSPATH);
}

Requesting static files

Now, if we visit /logo.png or /logs/hello.txt we will get the corresponding files. Note that /public/ is not part of the url.
