Making a Laravel app respond to Slack commands

This package makes it easy to make your Laravel app respond to Slack's Slash commands.

Once you've setup your Slash command over at Slack and installed this package into a Laravel app you can create handlers that can handle a slash command. Here's an example of such a handler that will send a response back to slack.

namespace App\SlashCommandHandlers;

use App\SlashCommand\BaseHandler;
use Spatie\SlashCommand\Request;
use Spatie\SlashCommand\Response;

class CatchAll extends BaseHandler
{
    /**
     * If this function returns true, the handle method will get called.
     *
     * @param \Spatie\SlashCommand\Request $request
     *
     * @return bool
     */
    public function canHandle(Request $request): bool
    {
        return true;
    }

    /**
     * Handle the given request. Remember that Slack expects a response
     * within three seconds after the slash command was issued. If
     * there is more time needed, dispatch a job.
     * 
     * @param \Spatie\SlashCommand\Request $request
     * 
     * @return \Spatie\SlashCommand\Response
     */
    public function handle(Request $request): Response
    {
        return $this->respondToSlack("You have typed this text: `{$request->text}`");
    }
}

This is the contents of the published file:

     * slack commands are posted. Specify the path component of that url here. 
     * 
     * For `http://example.com/slack` you would put `slack` here.
     */
    'url' => 'slack',

    /*
     * The token generated by Slack with which to verify if a incoming slash command request is valid.
     */
    'token' => env('SLACK_SLASH_COMMAND_VERIFICATION_TOKEN'),
    
    /*
     * The signing_secret generated by Slack with which to verify if a incoming slash command request is valid.
     */
    'signing_secret' => env('SLACK_SIGNING_SECRET'),

    /*
     * Verify requests from slack with signing_secret signature
     */
    'verify_with_signing' => false,

    /*
     * The handlers that will process the slash command. We'll call handlers from top to bottom
     * until the first one whose `canHandle` method returns true.
     */
    'handlers' => [
        //add your own handlers here


        //this handler will display instructions on how to use the various commands.
        Spatie\SlashCommand\Handlers\Help::class,

        //this handler will respond with a `Could not handle command` message.
        Spatie\SlashCommand\Handlers\CatchAll::class,
