A localization module for managing translations and providing localized content in your application.

## Installation

```
npm i @sern/localizer
```


import { Tabs, TabItem } from "@astrojs/starlight/components";


## Usage

**Initializing the Localizer**

<Tabs>
    <TabItem label ="src/index.js">
        ```ts {2} {6}
        import { makeDependencies } from '@sern/handler';
        import { Localization } from '@sern/localizer';

        await makeDependencies(({ add }) => {
            // add other deps
            add('localizer', Localization());
        });
        ```
    </TabItem>
        <TabItem label="src/dependencies.d.ts">
            ```ts {5}
            import type { Logging, CoreDependencies } from '@sern/handler'
            import type { Localizer } from '@sern/localizer'
            declare global {
                interface Dependencies extends CoreDependencies {
                    localizer: Localizer;
               }
            }
            export {}
            ```
        </TabItem>
</Tabs>

This localizer is **FILE BASED**.
Create the directory `assets/locals`. Each json file in here must be named after the `locale`


<Tabs>
  <TabItem label="Spanish">
    ```json title=~/assets/locals/es-ES.json
        {
            "salute": {
                "hello": "hola"
            }
        }
    ``` 
  </TabItem>
  <TabItem label="English">
    ```json title=~/assets/locals/en-US.json
        {
            "salute": {
                "hello": "hello"
            }
        }
    ``` 
  </TabItem>
</Tabs>



**Accessing translations**
- If you are in a command execute callback, use `deps` from SDT.
```ts 
execute : (ctx, { deps }) => {
    //the localizer object from makeDependencies
    deps.localizer
    // Returns the Spanish translation for 'salute.hello'
    deps.localizer.translate("salute.hello", "es-ES"); 
}
```


```ts
import { local } from '@sern/localizer';

// Returns the Spanish translation for 'salute.hello'
const greeting = local('salute.hello', 'es-ES'); 
```
