node.js, express.js - What is the easiest way to serve a single static file?

Question

I have already seen and made use of:

app.use("/css", express.static(__dirname + '/css')); 

I do not wish to serve all files from the root directory, only a single file, 'ipad.htm'. What is the best way to do this with the minimum amount of code, using express.js?

Answer 1

res.sendFile(path_to_file); is all you need; it will automatically set the correct headers and transfer the file (it internally uses the same code as express.static).

In express versions less than 4, use sendfile instead of sendFile.

Answer 2

app.use("/css/myfile.css", express.static(__dirname + '/css/myfile.css'));
