Express route in node JS invokes two routes

Question

I have below kind of route in my project

router.get('/new', async function(req,res){
});

router.get('/:id', async function (req, res) {
});

when I invoked /new route from post-man, both the routes are executing. first the route /new gets executed and then the route with /:id also getting invoked. I dont knw understand why its getting confused and triggers both routes. Please help. Thanks in advance.

Answer 1

This is because the route structure for both the endpoints are same. When you define a route /:id, it accepts some X value in the route. Now when you define your other as /new , express will consider new as the value of X and call that route too. Workaround for this is to change the structure of one of route. You should follow rest pattern to avoid such problems. You can read here
