base-uri: Get the base URI of your application
Returns the base URI where your application is running. This allows you to create applications that can be deployed at any sub-uri (e.g. with Passenger Phusion), without needing to hard code the path in your application.
In a Node environment, looks at PASSENGER_BASE_URI if it is present, and
otherwise defaults to /.
In a browser environment, looks at the location of the executing script, and takes the dirname of this. This assumes that your script is always located at the top of your application.
Installation
npm install base-uri --save
Usage
General
var baseURI = require('base-uri');
Express
Use the base URI to determine at which point to mount all your routes.
var app = express();
var baseURI = require('base-uri');
// Create all your routes
var router = express.Router();
router.get('/', function (req, res) {
res.send('Hello world');
});
// Mount the routes at the base URI
app.use(baseURI, router);
Browser
Use the base URI to create internal application links.
var baseURI = require('base-uri');
var $ = require('jquery');
$('body').append('<a href="' + baseURI + '/somewhere">Link</a>');
or with ES6
import baseURI from 'base-uri';
import $ from 'jquery';
$('body').append(`<a href='${baseURI}/somewhere'>Link</a>`));
