server.js

const 
    exp = require('express')
    ,app  =exp()
    ,server = require('http').Server( app )
    ,langs = require('express-langs')
;
 
app
    // ... , you other middleware
    .use( langs )
    // you other middleware ... ,
;
 
 
app
    .get('/' , (req,res) => {
 
        /**
         * array<object>
         *  {
         *      lang: string
         *      ,val: float
         *  }
         */
        console.log( req.langs.items );
 
        res.send( 'hello world !' ) ;
 
    } )
;
 
server.listen( 80 , () => console.log('server run ...') ) ;
 

you can use methods test exists langs

const 
    exp = require('express')
    ,app  =exp()
    ,server = require('http').Server( app )
    ,langs = require('express-langs')
;
 
app
    // ... , you other middleware
    .use( langs )
    // you other middleware ... ,
;
 
 
app
    .get('/' , (req,res) => {
 
        const langs = req.langs ;
 
        if( langs.exists( 'fr' ) ) {
 
 
            res.send( 'salut le monde !' ) ;
 
        } else {
 
            res.send('hello world') ;
        }
 
    } )
;
 
server.listen( 80 , () => console.log('server run ...') ) ;
 

exists methods make a relative test with langs found e.g :

langs.exists('en') ; // match with 'en-US'
langs.exists('en') ; // match with 'en'
langs.exists('en') ; // not match with 'fr'

or with an pattern e.g :

langs.exists( /en/i ) ; // match with 'en-US'
langs.exists( /en/i ) ; // match with 'en'
 
langs.exists( /en|fr/i ) ; // match with 'fr'

you can make a strict test exists e.g :

langs.existsStrict('en') ; // not match with 'en-US'
langs.existsStrict('en') ; // match with 'en'
langs.existsStrict('en') ; // not match with 'fr'

getWith method get array langs match with you support pattern

const supportLangs = langs.getWith( /en|fr|es/i ) ; // array[ langs ]
 
// you can give an string for build an pattern e.g :
const pattern = "en|fr|es" ;
const supportLangs = langs.getWith( pattern ) ; // array[ langs ]
