Data from users

Another technique that should be familiar to you if your background is classic ASP or MVC is form posting. With this approach, it is assumed that there is a screen into which a user is entering one or more fields and that the entire collection of those values needs to be quickly and easily transported to a URL. To implement form posting, instead of using a get function inside of your .js file, you need to use a post:

router.post('/survey', function (req, res) { });

As you can see, post is almost identical in signature to get. Before we get more deeply into it, just touching on the subject of post as an alternative to get leads us back into taking a brief look at the four basic actions universally available over an HTTP web connection:

Get A typical web request

Post Usually used for sending a collection of data to be processed

Put Usually used for updating a single record

Delete As you might have expected, usually used for deleting a single record

A file that contains routing information will typically contain at least one of each of the four methods just defined, like this:

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