I would like to be able to receive some parameter by url with nodejs I have tried it this way:
router.get('/events:id', (req,res) => {
var choice = req.params.id;
})
However I get this error:

In order for you to have the scenario that I propose to you, you must install express with the command npm i -S express and later have a code structure similar to the one I show you
Since you do not specify what technologies you use, I mention the following:
Inside your app.js file write the following:
const express = require('express')
const app = express()
app.get('/about/:name', (req, res) => {
res.send('Hello World:' + req.params.name)
})
app.listen(3000, () => {
console.log("Running")
})
req.params.nombre_variable
Remember that so far as I have code it is necessary Restart the service every time you type something if the changes do not will be seen with the command
node app.jsor the name that you have put to your file
UPDATE
If you want to save the data that arrives in a variable, you just have to do the next thing is to say your code should look similar to the following
const express = require('express')
const app = express()
app.get('/about/:name', (req, res) => {
const name = req.params.name
res.send('Hello World:' + name)
})
app.listen(3000, () => {
console.log("Running")
})
As you can notice in the previous example, I assign the constant
namewhat is received byreqwhich is therequestwhich in turn readsparamsand get the value of the variable that comes by URL calledname
