Make a Laravel app respond to a slash command from Slack

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}`");
    }
}

     */
    'verify_with_signing' => false,

     */
    'handlers' => [
        //add your own handlers here


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