## <a name="prerequisites"></a> Prerequisites
This library depends on `Angular v4.0.0`. Older versions contain outdated dependencies, might produce errors.

Also, please ensure that you are using **`Typescript v2.5.3`** or higher.

## <a name="getting-started"> Getting started
### <a name="installation"> Installation
You can install **`@ngx-config/fs-loader`** using `npm`
```
npm install @ngx-config/fs-loader --save
```

**Note**: You should have already installed [@ngx-config/core].

### <a name="examples"></a> Examples
- [ng-seed/universal] and [fulls1z3/example-app] are officially maintained projects, showcasing common patterns and best
practices for **`@ngx-config/fs-loader`**.

### <a name="related-packages"></a> Related packages
The following packages may be used in conjunction with **`@ngx-config/fs-loader`**:
- [@ngx-config/core]
- [@ngx-universal/config-loader]
- [@ngx-config/merge-loader]

### <a name="adding-systemjs"></a> Adding `@ngx-config/fs-loader` to your project (SystemJS)
Add `map` for **`@ngx-config/fs-loader`** in your `systemjs.config`
```javascript
'@ngx-config/fs-loader': 'node_modules/@ngx-config/fs-loader/bundles/fs-loader.umd.min.js'
```

## <a name="settings"></a> Settings
### <a name="setting-up-fsloader"></a> Setting up `ConfigModule` to use `ConfigFsLoader`
If you provide application settings using a `JSON` file (*on the `server platform`*), you can call the [forRoot] static
method using the `ConfigFsLoader`. By default, it is configured to retrieve **application settings** from the path `/config.json`
(*if not specified*).

> You can customize this behavior (*and ofc other settings*) by supplying a **file path** to `ConfigFsLoader`.

- Import `ConfigModule` using the mapping `'@ngx-config/core'` and append `ConfigModule.forRoot({...})` within the imports
property of **app.module**.
- Import `ConfigFsLoader` using the mapping `'@ngx-config/fs-loader'`.

**Note**: *Considering the app.module is the core module in Angular application*.

#### config.json
```json
{
  "system": {
    "applicationName": "Mighty Mouse",
    "applicationUrl": "http://localhost:8000"
  },
  "seo": {
    "pageTitle": "Tweeting bird"
  },
  "i18n":{
    "locale": "en"
  }
}
```

#### app.module.ts
```TypeScript
...
import { ConfigModule, ConfigLoader } from '@ngx-config/core';
import { ConfigFsLoader } from '@ngx-config/fs-loader';
...

export function configFactory(): ConfigLoader {
  return new ConfigFsLoader('./public/assets/config.json'); // FILE PATH
}

@NgModule({
  declarations: [
    AppComponent,
    ...
  ],
  ...
  imports: [
    ConfigModule.forRoot({
      provide: ConfigLoader,
      useFactory: (configFactory)
    }),
    ...
  ],
  ...
  bootstrap: [AppComponent]
})
```

`ConfigFsLoader` has one parameter:
- **path**: `string` : path to `JSON file`, to retrieve application settings from (*by default, `config.json`*)

> :+1: Well! **`@ngx-config/fs-loader`** will now provide **application settings** to [@ngx-config/core] using `fs`.
