Package Exports
- express-langs
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (express-langs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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 ]
