## Usage
|
||||
|
||||
### On the `store`
|
||||
`svelte-i18n` utilizes svelte `stores` for keeping track of the current locale, dictionary of messages and the main format function. This way, we keep everything neat, in sync and easy to use on your svelte files.
|
||||
|
||||
---
|
||||
|
||||
### Locale
|
||||
|
||||
The `locale` store defines what is the current locale.
|
||||
|
||||
```js
|
||||
import { i18n } from 'svelte-i18n'
|
||||
import { Store } from 'svelte/store'
|
||||
import { locale, dictionary } from 'svelte-i18n'
|
||||
|
||||
/** i18n(svelteStore, { dictionary }) */
|
||||
let store = new Store()
|
||||
// Set the current locale to en-US
|
||||
locale.set('en-US')
|
||||
|
||||
store = i18n(store, {
|
||||
dictionary: {
|
||||
'pt-BR': {
|
||||
message: 'Mensagem',
|
||||
greeting: 'Olá {name}, como vai?',
|
||||
greetingIndex: 'Olá {0}, como vai?',
|
||||
meter: 'metros | metro | metros',
|
||||
book: 'livro | livros',
|
||||
messages: {
|
||||
alert: 'Alerta',
|
||||
error: 'Erro',
|
||||
},
|
||||
// This is a store, so we can subscribe to its changes
|
||||
locale.subscribe(() => {
|
||||
console.log('locale change')
|
||||
})
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### The dictionary
|
||||
|
||||
The `dictionary` store defines the dictionary of messages of all locales.
|
||||
|
||||
```js
|
||||
import { locale, dictionary } from 'svelte-i18n'
|
||||
|
||||
// Define a locale dictionary
|
||||
dictionary.set({
|
||||
pt: {
|
||||
message: 'Mensagem',
|
||||
'switch.lang': 'Trocar idioma',
|
||||
greeting: {
|
||||
ask: 'Por favor, digite seu nome',
|
||||
message: 'Olá {name}, como vai?',
|
||||
},
|
||||
'en-US': {
|
||||
message: 'Message',
|
||||
greeting: 'Hello {name}, how are you?',
|
||||
greetingIndex: 'Hello {0}, how are you?',
|
||||
meter: 'meters | meter | meters',
|
||||
book: 'book | books',
|
||||
messages: {
|
||||
alert: 'Alert',
|
||||
error: 'Error',
|
||||
},
|
||||
photos:
|
||||
'Você {n, plural, =0 {não tem fotos.} =1 {tem uma foto.} other {tem # fotos.}}',
|
||||
cats: 'Tenho {n, number} {n,plural,=0{gatos}one{gato}other{gatos}}',
|
||||
},
|
||||
en: {
|
||||
message: 'Message',
|
||||
'switch.lang': 'Switch language',
|
||||
greeting: {
|
||||
ask: 'Please type your name',
|
||||
message: 'Hello {name}, how are you?',
|
||||
},
|
||||
photos:
|
||||
'You have {n, plural, =0 {no photos.} =1 {one photo.} other {# photos.}}',
|
||||
cats: 'I have {n, number} {n,plural,one{cat}other{cats}}',
|
||||
},
|
||||
})
|
||||
|
||||
/**
|
||||
* Extend the initial dictionary.
|
||||
* Dictionaries are deeply merged.
|
||||
* */
|
||||
store.i18n.extendDictionary({
|
||||
'pt-BR': {
|
||||
messages: {
|
||||
warn: 'Aviso',
|
||||
success: 'Sucesso',
|
||||
},
|
||||
},
|
||||
'en-US': {
|
||||
messages: {
|
||||
warn: 'Warn',
|
||||
success: 'Success',
|
||||
},
|
||||
},
|
||||
// It's also possible to merge the current dictionary
|
||||
// with other objets
|
||||
dictionary.update(dict => {
|
||||
dict.fr = {
|
||||
// ...french messages
|
||||
}
|
||||
return dict
|
||||
})
|
||||
|
||||
/** Set the initial locale */
|
||||
store.i18n.setLocale('en-US')
|
||||
```
|
||||
|
||||
### On `templates`
|
||||
Each language message dictionary can be as deep as you want. Messages can also be looked up by a string represetation of it's path on the dictionary (i.e `greeting.message`).
|
||||
|
||||
#### Basic usage
|
||||
---
|
||||
|
||||
### Formatting
|
||||
|
||||
The `_`/`format` store is the actual formatter method. To use it, it's simple as any other svelte store.
|
||||
|
||||
```html
|
||||
<script>
|
||||
// locale is en
|
||||
import { _ } from 'svelte-i18n'
|
||||
</script>
|
||||
|
||||
<input placeholder="{$_('greeting.ask')}" />
|
||||
```
|
||||
|
||||
`svelte-i18n` uses `formatjs` behind the scenes, which means it supports the [ICU message format](http://userguide.icu-project.org/formatparse/messages) for interpolation, pluralization and much more.
|
||||
|
||||
```html
|
||||
<div>
|
||||
{$_('message')}: {$_('messages.success')}
|
||||
<!-- Message: SUCCESS-->
|
||||
{$_('greeting.message', { name: 'John' })}
|
||||
<!-- Hello John, how are you? -->
|
||||
|
||||
{$_('photos', { n: 0 })}
|
||||
<!-- You have no photos. -->
|
||||
|
||||
{$_('photos', { n: 12 })}
|
||||
<!-- You have 12 photos. -->
|
||||
</div>
|
||||
```
|
||||
|
||||
#### Current locale
|
||||
### Formatting methods
|
||||
|
||||
The current locale is available via `this.store.get().locale`.
|
||||
#### `_` / `format`
|
||||
|
||||
#### Interpolation
|
||||
`function(messageId: string, locale:? string): string`
|
||||
|
||||
`function(messageId: string, interpolations?: object, locale:? string): string`
|
||||
|
||||
Main formatting method that formats a localized message by its id.
|
||||
|
||||
```html
|
||||
<div>
|
||||
<!-- Named interpolation -->
|
||||
{$_('greeting', { name: 'John' })}
|
||||
<!-- Hello John, how are you?-->
|
||||
<script>
|
||||
import { _ } from 'svelte-i18n'
|
||||
</script>
|
||||
|
||||
<!-- List interpolation -->
|
||||
{$_('greetingIndex', ['John'])}
|
||||
<!-- Hello John, how are you?-->
|
||||
</div>
|
||||
<div>{$_('greeting.ask')}</div>
|
||||
<!-- Please type your name -->
|
||||
```
|
||||
|
||||
#### Pluralization
|
||||
#### `_.upper`
|
||||
|
||||
Transforms a localized message into uppercase.
|
||||
|
||||
```html
|
||||
<div>
|
||||
0 {$_.plural('meter', 0)}
|
||||
<!-- 0 meters -->
|
||||
<script>
|
||||
import { _ } from 'svelte-i18n'
|
||||
</script>
|
||||
|
||||
1 {$_.plural('meter', 1)}
|
||||
<!-- 1 meter -->
|
||||
|
||||
100 {$_.plural('meter', 100)}
|
||||
<!-- 100 meters -->
|
||||
|
||||
0 {$_.plural('book', 0)}
|
||||
<!-- 0 books -->
|
||||
|
||||
1 {$_.plural('book', 1)}
|
||||
<!-- 1 book -->
|
||||
|
||||
10 {$_.plural('book', 10)}
|
||||
<!-- 10 books -->
|
||||
</div>
|
||||
<div>{$_.upper('greeting.ask')}</div>
|
||||
<!-- PLEASE TYPE YOUR NAME -->
|
||||
```
|
||||
|
||||
#### Utilities
|
||||
#### `_.lower`
|
||||
|
||||
Transforms a localized message into lowercase.
|
||||
|
||||
```html
|
||||
<div>
|
||||
{$_.upper('message')}
|
||||
<!-- MESSAGE -->
|
||||
<script>
|
||||
import { _ } from 'svelte-i18n'
|
||||
</script>
|
||||
|
||||
{$_.lower('message')}
|
||||
<!-- message -->
|
||||
|
||||
{$_.capital('message')}
|
||||
<!-- Message -->
|
||||
|
||||
{$_.title('greeting', { name: 'John' })}
|
||||
<!-- Hello John, How Are You?-->
|
||||
</div>

# svelte app
|
||||
|
||||
This is a project template for [Svelte](https://svelte.dev) apps. It lives at https://github.com/sveltejs/template.
|
||||
|
||||
To create a new project based on this template using [degit](https://github.com/Rich-Harris/degit):
|
||||
|
||||
```bash
|
||||
npx degit sveltejs/template svelte-app
|
||||
cd svelte-app
|
||||
```
|
||||
|
||||
*Note that you will need to have [Node.js](https://nodejs.org) installed.*
|
||||
|
||||
|
||||
## Get started
|
||||
|
||||
Install the dependencies...
|
||||
|
||||
```bash
|
||||
cd svelte-app
|
||||
npm install
|
||||
```
|
||||
|
||||
...then start [Rollup](https://rollupjs.org):
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
```
|
||||
|
||||
Navigate to [localhost:5000](http://localhost:5000). You should see your app running. Edit a component file in `src`, save it, and reload the page to see your changes.
|
||||
|
||||
|
||||
## Deploying to the web
|
||||
|
||||
### With [now](https://zeit.co/now)
|
||||
|
||||
Install `now` if you haven't already:
|
||||
|
||||
```bash
|
||||
npm install -g now
|
||||
```
|
||||
|
||||
Then, from within your project folder:
|
||||
|
||||
```bash
|
||||
now
|
||||
```
|
||||
|
||||
As an alternative, use the [Now desktop client](https://zeit.co/download) and simply drag the unzipped project folder to the taskbar icon.
|
||||
|
||||
### With [surge](https://surge.sh/)
|
||||
|
||||
Install `surge` if you haven't already:
|
||||
|
||||
```bash
|
||||
npm install -g surge
|
||||
```
|
||||
|
||||
Then, from within your project folder:
|
||||
|
||||
```bash
|
||||
npm run build
|
||||
surge public
|
||||
```
