API Gateway

Assume that your server has few endpoints and instead of making a separate request for each of them you want to make only single request and get all data at once. This module intended to make it possible.

Usage

npm i --save api-gateway-test

const app = require('express')();

const gateway = require('api-gateway-test');

app.use(...);

app.use(gateway);

Example

Assuming that the server has routes /api/users, /api/countries and so on, making a request to /api/resources with specified parameters should return joint data for each of underlying resources.

Request to enpoint like /api/users could be configured with environment variables:
process.env.PROTOCOL (default http)
process.env.HOSTNAME (default localhost)
process.env.PORT (default 3000)
process.env.TIMEOUT (default 30sec)
The value of /api/resources also configurable by process.env.RESOURCES

http://localhost:3000/api/resources?users=/api/users&countries=/api/countries&user=/api/users/user1&customers=/api/customers

http://localhost:3000/api/resources?user=/api/users/1&countries=/api/countries

http://localhost:3000/api/resources?unknown=/api/unknown

http://localhost:3000/api/resources?timeout=/api/unresponsible
