You need to have nodejs, npm, express and mustache installed.
``bash`
$ npm install @narando/express-preferred-ui-language
The middleware will get the availabel languages from ./app/locales/:
`javascript
import preferredUILanguage from "@narando/express-preferred-ui-language";
// add middleware to express
app.router(preferredUILanguage());
`
To add a language you have to create a new file at ./app/locales. The file name will be used as the language identifier.
#### Folder structure
`
app
|-locales
|-de-DE.json
|-en-US.json
#### Locale file structure
`json`
{
"namespace1": {
"text1": "First text",
"text2": "Second text"
},
"namespace2": {
"text3": "Third text",
"text4": "Fourth text"
}
}
The middleware will set the res.locals like:
`
[
{ languageCode: "de-DE", selected: true },
{ languageCode: "en-US", selected: false }
]
