Communications

• Messaging (AMQP): RabbitMQ

• XMPP, Ejabberd, Prosody

• Webhooks


Webooks can help you with the infrastructure. Some service is too heavy? - move it to another machine and connect them with webhook. Think about webhooks even when on a single machine (call by URL, not by function name)

Image from the presentation “Using Web Hooks”

Hooks

• Subversion pre-commit, post-commit

• Git, Mercurial - あります

• Rails: :before_save, :after_delete



Unix Philosophy

• do ONE THING and do it well

• programs WORK TOGETHER

• UNIVERSAL INTERFACE (text)


Insert here more about the webhooks - POST, etc.example cat | grep | mail -> make this with web too (demo)

What are WEBhooks?

webhooks are user defined callback URLs, that point to a web script to run on a

certain event


By letting the user specify a URL for various events, the application will POST data to those URLs when the events occur. Key poins: USER DEFINED, URLs (remote services), RUN ON CERTAIN EVENT (push, no cronjobs etc.)
