var dependency = require('tilestrata-dependency');
 
server.layer('mylayer').route('tile.png')
    .use(/* provider */);
 
server.layer('mylayer').route('tile.jpg')
    .use(dependency('mylayer', 'tile.png'))
    .use(/* transform */)
 
// or if you want to dynamically serve different tiles
// based on the request, you can provide a function:
server.layer('mylayer').route('tile.jpg')
