What?
---
!Caddis Fly Lure
A caddis is a moth-like insect often used as models for fly lures in fishing.

The caddis CLI tool is used to start and stop a RESTful JSON service with the ability to POST route configuration and responses, on-the-fly, for mocking and testing purposes.

_It may be a stretch, but there's wit in there somewhere..._

Why?
---
There are other projects I have been a part of, such as madmin, that allow for dynamically creating RESTful APIs through a User Interface and allows for persistance through I/O.

Recently, I was involved with mocking a service layer for unit testing purposes and found that the manual curation of such an API was too tedious for the task at hand - I wanted the process to be much more fluid and simple.

In this particular instance I needed to:

1. Start a server in setup/before
2. Dynamically add a route to the service with mock JSON response
3. Run the test
4. Shut down the server in teardown/after

Fairly simple, and most of all I didnt want any artifacts lying around - in other words I didn't need for any routes that I dynamically created to stick around on my local disk after the tests were done.

As such, caddis was born.

How
---
As mentioned briefly above, caddis is a CLI tool. It is recommended to install globally:

`
$ npm install -g caddis
`
_: you may need to sudo_

Once installed, you can start the service (currently defaults to http://localhost:3001) and begin POSTing route configurations in JSON. Here is an example using cUrl that dynamically adds a GET route at /foo with a simple JSON payload of {"bar":"baz"}:

`
$ curl -X POST -d '{"method":"GET", "uri":"/foo", "response":{"bar":"baz"}}' http://localhost:3001/api --header "Content-Type:application/json"
`

You are not confiuned to cUrl - you can use whatever networking library in whatever language you are writing your tests in and the server can handle all modern RESTful methods:

* GET
* POST
* PUT
* DELETE

When you are finished, simply stop the caddis server:

`
$ caddis stop
`

Post Data

`
$ npm run test
