How to Use

const lang = {
    common: {
        hello_world: 'Hello, world!'
    }
};

<Translatable
    lang={lang}
    content={{
        transKey: 'common.hello_world'
    }}
/>

Will render the following:

<span>Hello, world!</span>

With children

const lang = {
    common: {
        first_name: 'First name'
    }
};

<Translatable
    lang={lang}
    attributes={{
        placeholder: {
            transKey: 'common.first_name'
        }
    }}
>
    <input type="text" />
</Translatable>

Will render the following:

<input type="text" placeholder="First name" />

Messages source format

The messages source format should look like the following:

{
    name: {
        key1: 'value1',
        key2: 'value2',
        // ... and more key-value pairs.
    },
    name: {
        key1: 'value1',
        key2: 'value2',
        // ... and more key-value pairs.
    },
    // ... and more locales.
}

Properties

The component MUST receive the lang property AND either a content property OR an attributes property.

You can also add a reference property that accepts a function that will receive the translated string.

This is handy for using the translated string outside of the render method.

e.g.

class HelloWorld extends Component {
    bindTranslation = translatedString => {
        this.translation = translatedString;
    }

    render() {
        return (
            <div>
                <Translatable
                    lang={lang}
                    content={{
                        transKey: 'common.hello_world'
                    }}
                    reference={this.bindTranslation}
                />
            </div>
        );
    }
}
