GitHub adapter for the laravel-bootdesk multi-platform messaging framework.

Install

composer require bootdesk/chat-sdk-adapter-github

Requires a PSR-18 HTTP client (guzzlehttp/guzzle, symfony/http-client, etc.) and a PSR-17 factory (nyholm/psr7 bundled).

Configuration

Variable	Description	Example
`auth_token`	GitHub token (PAT for PAT mode, optional for App mode)	`ghp_abc123...`
`http_client`	PSR-18 HTTP client instance	`new GuzzleHttp\Client`
`webhook_secret`	Webhook Secret	`my-secret...`
`app_id`	GitHub App ID (App mode)	`123456`
`installation_id`	Fixed installation ID (single-tenant App mode)	`654321`
`private_key`	App private key PEM (base64-encoded, App mode)	`LS0tLS1CRUdJTiBSU0EgUFJJVkFURS...`

PAT mode

$adapter = new GitHubAdapter(
    httpClient: new \GuzzleHttp\Client,
    webhookSecret: env('GITHUB_WEBHOOK_SECRET'),
    authToken: env('GITHUB_AUTH_TOKEN'),
);

Single-tenant App mode

$adapter = new GitHubAdapter(
    httpClient: new \GuzzleHttp\Client,
    webhookSecret: env('GITHUB_WEBHOOK_SECRET'),
    authToken: env('GITHUB_AUTH_TOKEN'), // optional fallback
    appId: env('GITHUB_APP_ID'),
    installationId: env('GITHUB_INSTALLATION_ID'),
    privateKey: env('GITHUB_PRIVATE_KEY'),
);

Multi-tenant App mode

$adapter = new GitHubAdapter(
    httpClient: new \GuzzleHttp\Client,
    webhookSecret: env('GITHUB_WEBHOOK_SECRET'),
    authToken: env('GITHUB_AUTH_TOKEN'), // optional fallback
    appId: env('GITHUB_APP_ID'),
    privateKey: env('GITHUB_PRIVATE_KEY'),
);

Laravel

The ChatServiceProvider auto-binds Psr\Http\Client\ClientInterface to GuzzleHttp\Client. Add to config/chat.php:

'github' => [
    'auth_token'     => env('GITHUB_AUTH_TOKEN'),
    'webhook_secret' => env('GITHUB_WEBHOOK_SECRET'),
],

Quick Example

// Post a comment on a pull request
$adapter->postMessage('github:owner/repo:42', 'LGTM!');

// Post a comment on an issue
$adapter->postMessage('github:owner/repo:issue:15', 'Thanks for reporting.');

// Reply to a review comment thread
$adapter->postMessage('github:owner/repo:42:rc:9876543', 'Fixed in abc123.');
