nodezoo-coveralls

• Lead: Mihai Dima
• Sponsor: nearForm

A microservice that provides Coveralls data for NodeZoo org. This microservice depends on Coveralls and the NPM registry but also caches retrieved data to reduce load on both public registries.

Please see the Nodezoo System for more details.

If you're using this microservice, and need help, you can:

• Post a github issue,
• Tweet to @nodezoo,
• Ask on the Gitter.

Install

• clone this repo into a root /nodezoo folder
• run npm install

Running

This micro-service can be ran as part of a complete system or as a single isolated unit.

As a complete system

A special system repository is available that runs the complete system using Docker and Fuge.

• Nodezoo: The complete system

Isolated mode

To make testing easier this micro-service can be ran in 'isolated' mode. This mode allows testing over http using a well defined port. Please note isolated mode means patterns are not exposed via mesh.

To run in isolated mode:

• Clone this repository locally,
• Run npm install,
• Run npm start isolated.

A simple http service is supported and can be called using Curl or other Rest clients. The default port is 8054. It can be changed using the COVERALLS_PORT environment variable.

Using with Curl

Any of the messages above can be run using curl in the following format in the command line

curl -d '{"role":"coveralls","cmd":"get","name":"YOUR_TEXT_HERE"}' http://localhost:8054/act
