Express.js：路由中的正则表达式

Question

I want to get a value in my url.

My url is like :

host/:value.schema

I want to get value.

Exemple :

host/horse.schema value = horse

I have another route without .schema:

host/:value

Exemple :

host/horse value = horse

How tell Express to make the difference ?

You can try something like this:

app.get('/:value.:schema?', function (req, res) {
  console.log(req.params);
});

You'll receive this:

http://localhost:3000/horse        { value: 'horse', schema: undefined }
http://localhost:3000/horse.schema { value: 'horse', schema: 'schema' }
