How to write minimal Slack script without a server?
<p>I joined a Slack team and now I want to play with the bots there. But there seem to be lots of different ways and they all involve some server with API.</p>

<p>Isn't there an easy way to write a script (is that a bot) for end users? I write a file, load it into the slack app and it works?</p>

<p>My first idea (just to try it out) was to respond to certain keywords automatically from my own account.</p>
