Express.js – app.enable() Method
The app.enable() function sets the Boolean setting ‘name’ to ‘true’, where name defines one of the properties from the app settings table. Using the app.set('foo', true) for a Boolean property is same as calling the app.enable('foo') function.
Syntax
app.enable(name)
Example 1
Create a file with the name "appEnable.js" and copy the following code snippet. After creating the file, use the command "node appEnable.js" to run this code.
// app.enable() Method Demo Example
// Importing the express module
const express = require('express');
// Initializing the express and port number
var app = express();
// Initializing the router from express
var router = express.Router();
var PORT = 3000;
app.enable('trust proxy')
console.log(app.get('trust proxy'));
// App listening on the below port
app.listen(PORT, function(err){
if (err) console.log(err);
console.log("Server listening on PORT", PORT);
});Output
C:\home
ode>> node appEnable.js true Server listening on PORT 3000
