Question

Determine the standard query path by parsing the RESTful URL (Remove the resource identifiers) using JavaScript

I have a URL structure designed in RESTFUL format, for example:

GET /street/:streetName/house/:houseNumber

or

GET /street/:streetName/house/listings

. The placeholders :streetName and :houseNumber represent specific resources. I am looking to extract the common elements from the URL for future logic operations, essentially isolating /street/house and /street/house/listings (remove all resource-specific parts of the URL).

I have searched for a JavaScript library to assist with this task but have not found one yet. Any suggestions?

PS: One approach I considered was using string manipulation techniques such as splitting by "/" and then concatenating the key terms while ignoring the specific resource names. However, this method does not seem very reliable.

Answer №1

If you want to ensure that each URL pattern has a corresponding route, one way to achieve this is by adding an extra property called req.staticParts in every middleware function:

app.get("/street/:streetName/house/:houseNumber", function(req, res, next) {
  req.staticParts = "/street/house";
  ...
})
...
.get("/street/:streetName/house/:houseNumber/listings", function(req, res, next) {
  req.staticParts = "/street/house/listings";
  ...
})
.use(function(req, res) {
  performAdditionalLogic(req.staticParts);
});

By explicitly setting the staticParts property, you can avoid the need for string manipulation and make your code more resilient.

Trying to parse the URL into staticParts without knowing the routes beforehand can be problematic. For instance, if you attempt to parse the URL /street/house/25 based on keywords, it would result in

req.staticParts = "/street/house"

, even though there might not be a matching route for it.
