react-lang-dropdown

Short Description

An easy way to implement a dropdown-menu to react and update the content with the new language.

The library adds a custom hook to your client, that takes an language-object or json-file as argument. These need to have a certain structure to work with the dropdown-menu. It is strongly recommended to use this package together with the npx-languages-package.

Quick-start

Installing the package (inside the client-folder).

    npm i react-lang-dropdown

The package provides two function:

.autochange()

• takes the default-language as argument {default: 'en'}
• creates no dropdown-menu
• changes the language automatic to the location or prefered language of the user
• if the prefered language is not available, it presents the default-language (preset is english).

.useDropdown(languagesObject, {options})

• takes an object of languages as mandatory argument
• takes an optional options-object as second argument

• default: sets the default language. Preset is english
• naming: sets the way of presentation.
• "default" presents the language in english-characters.
• "native" presents the language in the native characters and language
• "emoji" presents the language-choice in form of a flag (if available)

The languages-parameter needs to be an object that has a bcp-47-standard as key and a language-object as value. The language-object should hold the name, nativename, bcp-47 and a flag-emoji.

"en":{
        "name":"English",
        "emoji": "🇬🇧",
        "nativeName":"English",
        "content": "{}",
        "bcp47": "en"
    }

It is strongly recommended to use the "npx-languages" npm-package to provide the correct syntax and structure for this.

Code examples

In the App.js import the library and use it like a normal custom hook. It takes a

    import languageDropdown from 'react-lang-dropdown';
    import languages from './lang/languages.json';
...
    function App() {
      const [language, LanguageDropdown] = languageDropdown.useDropdown(languages);
    ...
    }

    ...

    return (
    <div className="App">
        <LanguageDropdown />
    </div>
    )
