chappai v1.9.2
Chappai
In a Micro-Service Architecture, you have to handle the proxying, the load, and at least failures.
One of the mandatory component is a Gateway
.
The main goal of a Gateway
is to keep track of all services registered,
to authorize or not a user to access requested services, and if needed,
to render data to fit with clients needs.
With Chappai (pronounced "Cha-Pa-Eye") you can monitor services, register you APIs and define custom data renders.
The registry part is handled by another library called Yemma. Feel free to checkout this project documentation to know more about the registry.
Setup
In a classic nodeJS project, install the dependency.
npm i --save chappai
In your main nodeJS file application (typically index.js) use it like so :
const gateway = require('chappai'); gateway .on(started, app => console.log(`Gateway listening on port ${app.settings.port}`)) .start();
Setup your environment:
export YEMMA_DB_URI=mongodb://localhost:27017/yemma export YEMMA_PORT=9000 export PORT=6473 # Mandatory(*) For Authentication part export AUTH_REALM=auth export AUTH_PATH=/api/v1/users/profile export AUTH_HEADER=authorization # Optional(*) For Access Control part export ACCESS_REALM=access
