JavaScript Exoservice Framework

opinionated framework for creating Exosphere lambda services in Node.JS

Installation

npm install -g exoservice-js

Creating a micro-service

Let's create the simplest possible microservice: when receiving the message "ping", it replies with the message "pong".

1. create an empty service scaffold

   • yo exoservice ping

2. start your server: SERVICE_NAME=pinger EXORELAY_PORT=3000 EXOCOM_PORT=3100 exo-js

   • SERVICE_NAME is as what your service should identify to Exosphere
   • EXORELAY_PORT is the port at which your service listens to Exosphere messages
   • EXOCOM_PORT is the port at which your local ExoCom instance runs

Testing

Test a running service manually:

$ curl -d '{"id": "123" }' -H "Content-Type: application/json" -i http://localhost:3000/run/hello-world
