Express.js App Path Method

The app.path() method returns the canonical path. The path is returned as a string. It is better to use the req.baseUrl method since the app.path() method can be very complicated in complex cases of mounted apps.

Syntax

app.path( )

Example 1

Create a file with the name "appPath.js" and copy the following code snippet. After creating the file, use the command "node appPath.js" to run this code.

// app.path() Demo Example

// Importing the express module
var express = require('express');

// Initializing the express and port number
var app = express();
var PORT = 3000;

// Assigning express constructor
var app = express()
var blog = express()
var blogAdmin = express()

// Assigning the below url's
app.use('/api', blog)
blog.use('/v1', blogAdmin)

// printing values as per the URLs
console.dir(app.path())
console.dir(blog.path())
console.dir(blogAdmin.path())

Output

C:\home
ode>> node appPath.js
''
'/api'
'/api/v1'

Example 2

Let’s take a look at one more example

// express.raw() Demo Example

// Importing the express module
var express = require('express');

// Initializing the express and port number
var app = express();
var PORT = 3000;

// Assigning express constructor
var app = express()
var blog = express()

// Assigning the below url's
app.use('/api', blog)
app.use('/v1', blog)

// printing values as per the URLs
console.dir(app.path()) // ''
console.dir(blog.path()) // '/blog'

Output

C:\home
ode>> node appPath.js
