Cannot Getting data from url query parameters. from a node rest api - node.js

Question

I have this code to make a get, post, put and delete request,
const express = require("express");
const TutorialModel = require("../models/tutorialModel");
const router = express.Router();
router.post("/tutorials", async (req, res) => {
try {
const tutorial = new TutorialModel(req.body);
const createTutorial = await tutorial.save();
res.status(201).send(createTutorial);
} catch (e) {
res.status(400).send(e);
}
});
router.get("/tutorials", async (req, res) => {
try {
const TutorialsData = await TutorialModel.find();
res.status(200).send(TutorialsData);
} catch (e) {
res.status(404).send(e);
}
});
router.get("/tutorials/:id", async (req, res) => {
try {
const _id = req.params.id;
const TutorialData = await TutorialModel.findById(_id);
if (!TutorialData) {
res.status(404).send();
} else {
res.send(TutorialData);
}
} catch (e) {
res.status(500).send(e);
}
});
router.get("/tutorials/:title", async (req, res) => {
try {
const _title = req.params.title;
const TutorialData = await TutorialModel.find({ title: _title });
if (!TutorialData) {
res.status(404).send();
} else {
res.send(TutorialData);
}
} catch (e) {
res.status(500).send(e);
}
});
router.put("/tutorials/:id", async (req, res) => {
try {
const _id = req.params.id;
const updateTutorial = await TutorialModel.findByIdAndUpdate(
_id,
req.body,
{ new: true }
);
res.send(updateTutorial);
} catch (e) {
res.status(400).send(e);
}
});
// Deleting student data by its Id
router.delete("/tutorials/:id", async (req, res) => {
try {
const _id = req.params.id;
const deleteTutorial = await TutorialModel.findByIdAndDelete(_id);
if (!_id) {
return res.status(400).send();
} else {
res.send(deleteTutorial);
}
} catch (e) {
res.status(500).send(e);
}
});
router.delete("/tutorials", async (req, res) => {
try {
const deleteTutorial = await TutorialModel.remove();
if (!deleteTutorial) {
return res.status(400).send();
}
else {
res.send(deleteTutorial);
}
} catch (e) {
res.status(500).send(e);
}
});
module.exports = router;
I've successfully made all request including get request with 'id' But when I try to make get request using 'title' parameter I'm getting data of get request of "/tutorials" not of "tutorials/:title". What is the issue? Can anyone tell me please?

Answer 1

The route GET "/tutorials/:id" will catch all your GET requests like /tutorials/something. It does not distinguish if you pass an id or a title.
:id is used to tell Express to capture the something path in the URL in req.params.id. That's all.
If you want to have another route to get tutorials by title, you should use another form. For example, GET "/tutorialsByTitle/:title".
