Getting Started
---------------

[](#getting-started)

These instructions will help you install this library in your project and tell you how to use it.

### Prerequisites

[](#prerequisites)

- PHP 8.2 or higher
- Symfony 6.0 or higher
- Composer for dependency management

### Installing

[](#installing)

#### Step 1: Install Package

[](#step-1-install-package)

```
composer require iwf-web/json-request-check-bundle
```

#### Step 2: Register Bundle (Symfony < 5.0)

[](#step-2-register-bundle-symfony--50)

For Symfony versions before 5.0, you need to manually register the bundle in your `config/bundles.php`:

```
// config/bundles.php
return [
    // ...
    IWF\JsonRequestCheckBundle\IWFJsonRequestCheckBundle::class => ['all' => true],
];
```

### Configuration

[](#configuration)

Create a configuration file at `config/packages/iwf_json_request_check.yaml`:

```
iwf_json_request_check:
    default_max_content_length: 10240 # Default: 10KB
```

Alternatively, you can define the default value as an environment variable in your `.env` file:

```
# .env or .env.local
IWF_JSON_REQUEST_CHECK_DEFAULT_MAX_LENGTH=10240
```

and then use it in your configuration file:

```
# config/packages/iwf_json_request_check.yaml
iwf_json_request_check:
    default_max_content_length: '%env(int:IWF_JSON_REQUEST_CHECK_DEFAULT_MAX_LENGTH)%'
```

To have a clue about size you can find a file with a JSON of **4kb** in the examples: [example-payload-4kb.json](examples/files/example-payload-4kb.json)
