# FicusJS internationalization (i18n)

Functions for managing translations and localization in FicusJS components.

For documentation visit [https://docs.ficusjs.org/i18n/](https://docs.ficusjs.org/i18n/)

## Getting started

FicusJS i18n can be used in any FicusJS component. It is recommended to use the `withI18n` or `withI18nReactive` functions to make translations available in the component.

```js
import { createCustomElement, createI18n, withI18n } from 'https://cdn.skypack.dev/ficusjs@6'
import { html, renderer } from 'https://cdn.skypack.dev/@ficusjs/renderers@5/uhtml'

// create the i18n instance
const i18n = createI18n()

// change interpolation delimiters from {{}} to $
i18n.interpolateWith(/\$(\w+)/g)

// populate the messages
i18n.add({
  projectTitle: 'Project title',
  button: {
    text: 'Click me $userName!',
    caption: 'Please click me!'
  },
  itemsCaption: [
    '$count item',
    '$count items'
  ],
  deep: {
    nested: {
      label: 'Deep nested label'
    }
  }
})

// Use the i18n instance in a new component
createCustomElement(
  'i18n-messages',
  withI18n(i18n, {
    renderer,
    render () {
      return html`
        <h1>i18n messages</h1>
        <dl>
          <dt>Title</dt>
          <dd>${this.i18n.t('projectTitle')}</dd>
          <dt>Button text</dt>
          <dd>${this.i18n.t('button.text', { userName: 'George' })}</dd>
          <dt>Button caption</dt>
          <dd>${this.i18n.t('button.caption')}</dd>
          <dt>Items caption</dt>
          <dd>${this.i18n.t('itemsCaption', { count: 0 })}</dd>
          <dd>${this.i18n.t('itemsCaption', { count: 1 })}</dd>
          <dd>${this.i18n.t('itemsCaption', { count: 2 })}</dd>
          <dt>Deep nested label</dt>
          <dd>${this.i18n.t('deep.nested.label')}</dd>
        </dl>
      `
    }
  })
)
```

## Installation

FicusJS i18n is a core part of [FicusJS](https://docs.ficusjs.org) but can also be installed independently in a number of ways.

### CDN

We recommend using native ES modules in the browser.

```html
<script type="module">
  import { createI18n, getI18n, withI18n, withI18nReactive } from 'https://cdn.skypack.dev/@ficusjs/i18n'
</script>
```

FicusJS i18n is available on [Skypack](https://www.skypack.dev/view/@ficusjs/i18n).

### NPM

FicusJS i18n work nicely with build tools such as Snowpack, Webpack or Rollup. If you are using a NodeJS tool, you can install the NPM package.

```bash
npm install @ficusjs/i18n
```

### Available builds

FicusJS i18n only provides ES module builds. For legacy browsers or alternative modules such as CommonJS, it is recommended to use a build tool to transpile the code.
