Installation

Add the following dependency to your project.clj file:

Clojars Project

Documentation

You can find a quick-start, example code, and lots and lots of documentation in our:

Lein Template

A Leiningen template is available that shows a suggested project structure:

lein new trapperkeeper my.namespace/myproject

Once you've created a project from the template, you can run it via the lein alias:

lein tk

Note that the template is not intended to suggest a specific namespace organization; it's just intended to show you how to write a service, a web service, and tests for each.

Related Projects

Here are some additional projects that provide Trapperkeeper services, and other related functionality:

  • trapperkeeper-webserver-jetty9: a Jetty9-based webserver for use with TK applications
  • trapperkeeper-rpc: a TK service that allows you to easily build a way to call remote TK services over RPC
  • trapperkeeper-metrics: a TK service that manages the life cycle of a MetricRegistry, so that all of your TK services can register metrics with a common configuration syntax.
  • trapperkeeper-comidi-metrics: a TK utility library that provides middleware to automatically generate metrics for all requests to each of your bidi/comidi HTTP routes.
  • trapperkeeper-status: a TK service that provides a mechanism for registering status callbacks for all of your other TK services, and web API for requesting status information about the entire TK system.
  • trapperkeeper-scheduler: a TK service that provides an API for scheduling periodic background tasks
