This **Symfony Bundle** is useful if you need to expose constants to front.

Install
-------

[](#install)

### Composer

[](#composer)

`composer require constant-exposure/constant-exposure-bundle:^2.2`

### Load the bundle

[](#load-the-bundle)

In `config/bundles.php`, add this line:

```
return [
    ...
    ConstantExposureBundle\ConstantExposureBundle::class => ['all' => true],
];
```

Usage
-----

[](#usage)

### Define constants to expose

[](#define-constants-to-expose)

Create a file `config/packages/constant_exposure.yaml` in your project. Then, configure constants to expose.

```
constant_exposure:
    parameter:
        debug: '%kernel.debug%'
        sentry_dsn: '%env(SENTRY_DSN)%'
        password_expire: !php/const App\Entity\Password::EXPIRE_PASSWORD
```

### Use constants in JavaScript

[](#use-constants-in-javascript)

Add this line in your Twig template. Pass as parameter a name for your JavaScript object.

```
{{ constant_exposure_object('ConstantExposure') }}
```

Get them in Javascript:

```
ConstantExposure.getParameter(PARAMETER_NAME [, DEFAUlT_VALUE = null] );
```

```
// Check if you are in debug mode
const isDebug = ConstantExposure.getParameter('debug');

// If sentry_dsn is not defined, default value is an empty string
const sentryDsn = ConstantExopsure.getParameter('sentry_dsn', '');
```

### Route exposure

[](#route-exposure)

If you need to expose your constants on a route, add these lines in your routing file:

```
constant_exposure:
    resource: "@ConstantExposureBundle/Resources/config/routing.yaml"
```

Then, you can access it with this url:

- /constant-exposure.json for a **JSON** format
- /constant-exposure.xml for a **XML** format
- /constant-exposure.csv for a **CSV** format
