Passing query parameter in nodejs but route is giving error - node.js

Question

I want to pass the query parameter in the route. I used authentication middleware.
I want to delete a task based on that task id. Later I want to pass auth into delete by id route and allow the user to delete a task by authentication, but when I pass the query parameter the endpoint fails. If no query parameter is passed everything works fine.
task.js
const express = require('express')
require('../mongoose')
const Task = require('../model/task_model')
const auth = require('../middleware/user_middleware')
const router = new express.Router()
router.delete('/tasks/del/:id', async (req, res) => {
try {
const task = await Task.findByIdAndDelete(req.params.id)
if (!task) {
res.status(404).send()
}
res.send(task)
} catch (e) {
res.status(500).send()
}
})
module.exports = router
index.js
const express = require('express')
const UserRouter = require('./router/user')
const TaskRouter = require('./router/task')
const app = express()
const port = process.env.PORT || 3000
app.use(express.json())
app.use(UserRouter)
app.use(TaskRouter)
app.listen(port,()=>{
console.log('Server listening on port: ' + port)
})
middleware.js
const jwt = require("jsonwebtoken")
const User = require("../model/user_model")
const auth = async function(req,res,next){
try {
const token = (req.headers.authorization).split(' ')[1]
const decoded_token = jwt.verify(token,'ankan123')
const user = await User.findOne({_id:decoded_token._id,"tokens.token":token})
if (!user){
throw new Error()
}
req.user = user
req.token = token
next()
} catch(e){
res.status(400).send("PLease Authenticate")
}
}
module.exports = auth
task_model.js
const mongoose = require('mongoose')
const TaskSchema = new mongoose.Schema({
task: {
type: String,
required:true,
},
completed:{
type: Boolean
},
creator:{
type: mongoose.Schema.Types.ObjectId,
required:true
}
})
const tasks = mongoose.model('Task', TaskSchema)
module.exports = tasks
user.js
const express = require('express')
require('../mongoose')
const User = require('../model/user_model')
const auth = require('../middleware/user_middleware')
const router = new express.Router()
router.post('/users/login', async (req, res) => {
try {
const user = await User.matchCred(req.body.mobileNo, req.body.password)
const token = await user.generateToken(user._id)
return res.status(200).send({
user,
token
})
} catch (e) {
res.status(400).send()
}
})
module.exports = router;
I am getting route containing /tasks/del/:id does not exist when using postman to send delete requests.

The issue is simple you are passing it as query parameters, but it is path parameters. You can run like this in the postman:
{url}/tasks/del/'yourID'
When you pass id as query parameters, it won't be able to match the path and hence you are receiving an error Can't Delete. I would say you should understand diff b/w them and you can check this link.
