Express.js - pass path parameter
3 points
In this article, we would like to show you how to get the path parameter in Express.js.
Quick solution:
xxxxxxxxxx1
app.get('/path/to/resource/:parameterName', (request, response) => {2
const parameterName = request.params.parameterName;3
// ...4
});
In this section, we present a practical example with GET method.
xxxxxxxxxx1
const express = require('express'); // npm install express2
3
const app = express();4
5
app.get('/users/:id', (request, response) => {6
const userId = request.params.id;7
// Do some operations here ...8
response.send(user);9
});10
11
app.listen(3000);Where: when GET request to /users/5 path is performed then request.params.id is set to 5.
