React multi labels

Provide static labels to your application, whichever language you want

How to use it

React multi labels rely on the React 16.3.*, this means that if you use an earlier version, it won't work.

Setup

Fist of all you have to initialize the provider by giving it the default language of our labels and the labels themselves:

import { LabelsProvider } from 'react-multi-labels';
import { App } from './app';
import React from 'react';
import { render } from 'react-dom';

const labels = {
    en_GB: {
        REMOVE: 'Remove',
        CREATE: 'Create',
        CHANGE: 'Change',
        EDIT: 'Edit'
    },
    it_IT: {
        REMOVE: 'Rimuovi',
        CREATE: 'Crea',
        CHANGE: 'Cambia',
        EDIT: 'Modifica'
    }
}

// 'en_GB' will be the first language
render(
    <LabelsProvider language={'en_GB'} labels={labels}>
        <App />
    </LabelsProvider>
    document.getElementById('app')
)

Consuming

The library provides different high order components to consume your labels.

import { Label } from 'react-multi-labels';

function Button() {
  return (
    <button>
      <Label text={'REMOVE'} />
    </button>
  );
}

// result will be <button>Remove</button> for 'en_GB'
// result will be <button>Rimuovi</button> for 'it_IT'

API

• Label
• GetLabel
• GetLabels
• ChangeLanguage
• ChangeLabels

Label

It simply returns the label that you want. It doesn't return any markup. Only text. If it doesn't exist, it will return undefined

GetLabel

High Order Component to return the label, so you can provide it all your components

import { GetLabels } from 'react-multi-labels';
import { Button } from './Button';
function Form() {
  return (
    <GetLabel text={'REMOVE'}>
      {label => {
        return <Button buttonLabel={label} />;
      }}
    </GetLabel>
  );
}

GetLabels

Sometimes you need to retrieve multiple labels in one go. You can use this guy. It's an high order component that requires an array of the labels that you want and it returns an object, so you can identify your labels with their own name.

import { GetLabels } from 'react-multi-labels';
import { Button } from './Button'
import React from 'react'

function Form () {
    return (
        <GetLabels list={['REMOVE', 'CREATE']}>
            {({ REMOVE, CREATE }) => {
                return (
                    <React.Fragment>
                        <Button buttonLabel={CREATE} />
                        <Button buttonLabel={REMOVE} />
                    </React.Fragment>
                )
            }}
        </GetLabel>
    )
}

ChangeLanguage

import { GetLabels, ChangeLanguage } from 'react-multi-labels';
import { Button } from './Button';
import React from 'react';

function Form() {
  return (
    <GetLabels list={['REMOVE', 'CHANGE']}>
      {({ REMOVE, CHANGE }) => {
        return (
          <React.Fragment>
            <Button buttonLabel={REMOVE} />
            <ChangeLanguage>
              {changeLanguage => {
                <Button
                  buttonLabel={CHANGE}
                  onClick={() => changeLanguage('it_IT')}
                />;
              }}
            </ChangeLanguage>
          </React.Fragment>
        );
      }}
    </GetLabels>
  );
}
