How can I use cors explicitly on specific routes only?

[patrick99e99]

The documentation for how this is used is shown as:

server.pre(cors.preflight);
server.use(cors.actual);

This would add cors for all endpoints in an application, which is not what I want. Instead, how can I add cors to only one specific route? In other words, say I want my server.get('/foo', fn) to use cors, but not server.get('/bar', fn) ... How can I do that?

I know this is old, but whatever, someone may find it useful...
You want to use something like:

// Do a preflight on OPTIONS requests
server.opts('/foo', cors.preflight) 

// Add the cors actual to the pre-middleware on GET requests to /foo
server.get('/foo', cors.actual, fn) 

// Do nothing with requests on /bar
server.get('/bar', fn)
