## How to use

### Step 1: Get secret and site keys

You need to receive your `siteKey` and `secretKey` for your domain from [Google reCAPTCHA v3 Admin Console](https://www.google.com/recaptcha/admin)

Login and Follow the steps on this page to include the reCAPTCHA on your website.

### Step 2: Initialization

- Make sure to register the provider inside `.adonisrc.json` file.

```json
{
"providers": [
"...other packages",
"adonis-recaptcha2"
]
}
```

- Add variables to `.env` file of project.

```txt
...
RECAPTCHA_SITE_KEY=YOUR_KEY
RECAPTCHA_SECRET_KEY=YOUR_KEY
```

- Add fields to `env.ts` file of project.

```ts
import Env from '@ioc:Adonis/Core/Env'

export default Env.rules({
// ...
RECAPTCHA_SITE_KEY: Env.schema.string(),
RECAPTCHA_SECRET_KEY: Env.schema.string(),
})
```

- Set options in `config/recaptcha.ts`.

```ts
import Env from '@ioc:Adonis/Core/Env'
import { RecaptchaConfig } from '@ioc:Adonis/Addons/Recaptcha2'

const recaptchaConfig: RecaptchaConfig = {
// ...
siteKey: Env.get('RECAPTCHA_SITE_KEY'),
// ...
secretKey: Env.get('RECAPTCHA_SECRET_KEY'),
}
export default recaptchaConfig
```

### Step 3: Add named middleware to `start/kernel.ts`

```ts
Server.middleware.registerNamed({
recaptcha: () => import('App/Middleware/Recaptcha')
})
```

### Step 4: Add middleware for `start/routes.ts`

Example:
```ts
Route.post('login', 'AuthController.login').middleware('recaptcha')
```

This middleware will check `g-recaptcha-response` field in body request
```json
{
"login": "admin",
"password": "admin",
"g-recaptcha-response": "osjoiadjaoisdjasijda..."
}
```
> Field `g-recaptcha-response` it is Google reCAPTCHA v2 response

> **Note:** Required [View](https://docs.adonisjs.com/guides/views/introduction) (@adonisjs/view)

### Step 1: Enable `views` in `config/recaptcha.ts`
```ts
const recaptchaConfig: RecaptchaConfig = {
// ...
views: true
}
```

### Step 2: Use `recaptcha()` function in templates

...

...
{{ recaptcha('script') }}


...
