Micro Gateway

This package is a API gateway designed to be used with Microservices. It is based on Express and provides an onboarding service for automatic onboarding of services. This is still in progress of development.

Installation

npm install --save micro-gateway

Usage

You have to create a JavaScript file that can be executed by NodeJS. Micro Gateway has to different ways of configuring the services.

Basic Usage

You can directly use the JavaScript API to configure the gateway.

const ApiGateway = require('../index.js');

const gateway = new ApiGateway();

gateway.addService({
    name: 'test',
    host: 'localhost',
    port: 2001,
    targetPath: '/api/v1.0'
});

(async () => {
    await gateway.listen(2000);
    console.log('Gateway started');
})();

Onboarding Service

Another option is to activate the onboarding service. This will create another express server on port 1234. Via this server you are able to configure the gateway using REST endpoints. Currently it is only able to onboard a service or to update an existing service by resending the create request.

Activation

const ApiGateway = require('../index.js');

const gateway = new ApiGateway();

gateway.activateOnboardingService();

(async () => {
    await gateway.listen(2000);
    console.log('Gateway started');
})();
