How to serve static files on a dynamic route using Express?
To serve static files on a dynamic route using Express, we can use the req.params property to get route parameters in our route handler.
For instance, we write
app.get("/user/:uid/files/*", (req, res) => {
const uid = req.params.uid;
const path = req.params[0] ? req.params[0] : "index.html";
res.sendFile(path, { root: "./public" });
});
to get the value of the uid route parameter with req.params.uid.
And we get the value of the * parameter with req.params[0].
Finally, we call res.sendFile to return the file response for the file at the path relative to the root folder.
Conclusion
To serve static files on a dynamic route using Express, we can use the req.params property to get route parameters in our route handler.
