# Slick (by slack-php)
A _slick_, single-file, dependency-free PHP micro-framework for building simple Slack apps.
**For something more robust, you should use our fully-featured [Slack PHP Framework][1].**
If you are new to Slack app development, you will want to learn about it on [Slack's website][2].
## Installation
### Requirements
Requires PHP 7.3+ with JSON support.
### Via Composer
We recommend using Composer to install Slick, so that autoloading and keeping it up-to-date are easy.
```
composer require slack-php/slick
```### Manual
However, since Slick has no dependencies, you can directly download and require `Slick.php` or copy & paste the code
directly into your project.(If you do end up doing this, let me know, because I will have no other way to track that it's happening.)
## Basic Usage
This small app responds to the `/cool` slash command by posting a message back to the conversation where
the slack command was used.> Assumptions:
>
> - You have required the Composer autoloader to autoload Slick, OR you have required `Slick.php` directly.
> - You have `SLACK_SIGNING_KEY` set in your environment such that it is present in `$_SERVER`.```php
route('command', '/cool', function (array $payload) {
return "Thanks for running the `{$payload['command']}` command. You are cool! :thumbsup:";
})
->run();
```_Want to run this example in your workspace? Check out the [Example App][3] using Docker._
### Breaking It Down
Let's add some comments to that last example, so you know what is going on.
```php
route(
// The payload type (e.g., command, block_actions, view_submission, shortcut, and others).
'command',
// The payload ID. It's different based on the type. For commands, it is the command name.
'/cool',
// The listener that handles the specific interaction's logic.
function (array $payload) {
// Any app logic can be done here, including calling Slack's APIs.
// Whatever you do, it should take less than 3 seconds, so you can "ack" before Slack's timeout.
// Whatever is returned will be included as part of the "ack" (response) body. You can return a string, an
// associative array, or JSON-serializable object. You should make sure that anything you include in the ack
// is supported by the type of interaction you are responding to. Many interactions don't require an ack
// body, so you can also return null, and empty string, or just omit a return statement, entirely.
return "Thanks for running the `{$payload['command']}` command. You are cool! :thumbsup:";
}
)
// Add as many routes as you need to handle all your interactions.
->route(...)
->route(...)
->route(...)
// Runs the Slack app. This includes the following steps:
// 1. Reads data from the current request (e.g., via $_SERVER and php://input).
// 2. Validates the request from Slack, including verifying the request signature from the header.
// 3. Parses the request body into an array of Slack payload data.
// 4. Determines the payload type and ID.
// 5. Executes one of the registered listeners based on the payload type and ID.
// 6. Acks (responds) back to Slack.
->run();
```## Customization
There isn't much to customize, but you can control the behavior of your Slick Slack app when:
1. The incoming request doesn't match one of your routes (`on404()`).
2. An error occurs while processing the incoming request (`orErr()`).```php
route(...)
->route(...)
->route(...)
->on404(function (array $payload) {
// Do something custom. This is essentially used as a catch-all listener.
// If you don't use on404(), then your app throws an error.
})
->onErr(function (Throwable $err) {
// Do something custom.
// If you don't use onErr(), then your app calls `error_log()` and acks with a 500-level response.
})
->run();
```## Helper Functions
If you want to do your own request handling, Slick provides some static helper methods that you can use independent from
the routing features.- `Slick::validateSignature(string $key, string $signature, int $time, string $body): void` – Validates a Slack request
signature using their v0 algorithm.
- `Slick::parseRequestBody(string $body): array` – Parses a request body into an associative array of Slack payload
data. Works for any payload type. Must provide the raw request body as a string (e.g., from `php://input`).
- `Slick::getPayloadType(array $payload): string` – Determines the payload type from an array of payload data.
- `Slick::getPayloadId(array $payload): string` – Determines the payloads routable ID from an array of payload data,
based on its type.
- `Slack::ack(string $ack): void` – Echos an "ack" response with suitable headers and status code.[1]: https://github.com/slack-php/slack-php-app-framework
