node / express REST API application - passing parameters to GET method

Do I need to create two separate methods, one that accepts a parameter and one that doesn't?

I'm guessing you posted this before even trying that?

The answer is yes.

Your route that accepts parameters should look like this:

app.get('/emergency/:id', function (req, res, next) {    var id = req.params.id;    console.log('The id: ' + id);});

node.js rest express

Yes,it is necessary to have two different functions that listen to each type of url.This is because The url

http://localhost/example/abcd will get received in router.get('/example/:username',testFunction1);

whereas

http://localhost/example will be received in router.get('/example',testFunction2);

Refer to the article: http://codewhoop.com/article/Nodejs%20Getting%20parameters%20through%20GET%20methodfor detailed explanation of procedure to fetch paramters through GET method in Nodejs.

node.js rest express

I am not sure will it work or not you can try some thing like this

app.get('/emergency/:var(:id/|)', function (req, res, next) {    var id = req.params.id;    console.log('The id: ' + id);});
