I want to serve static files as is commonly done with express.static(static_path) but on a dynamic route as is commonly done with 

app.get('/my/dynamic/:route', function(req, res){
    // serve stuff here
});

A solution is hinted at in this comment by one of the developers but it isn't immediately clear to me what he means.

express node.js

You can use res.sendfile or you could still utilize express.static:

const path = require('path');
const express = require('express');
const app = express();

// Dynamic path, but only match asset at specific segment.
app.use('/website/:foo/:bar/:asset', (req, res, next) => {
  req.url = req.params.asset; // <-- programmatically update url yourself
  express.static(__dirname + '/static')(req, res, next);
});         

// Or just the asset.
app.use('/website/*', (req, res, next) => {
  req.url = path.basename(req.originalUrl);
  express.static(__dirname + '/static')(req, res, next);
});

This should work:

app.use('/my/dynamic/:route', express.static('/static'));
app.get('/my/dynamic/:route', function(req, res){
    // serve stuff here
});

Documentation states that dynamic routes with app.use() works. See https://expressjs.com/en/guide/routing.html
