### This package includes instruments for creating:
- Gateways
- Microservices
- Sockets

### Installation:
```bash
npm i --save @lomray/microservice-nodejs-lib
```

## Investigate
Take a look at [Microservices](https://github.com/Lomray-Software/microservices) to more understand how it works.

### Example
Go to `example` folder and check out the example of creating __microservice__ and __gateway__.
See `example/scratch.http` for understanding how to send requests.

1. install dependencies: `npm ci`
2. run ijson: `docker-compose up`
3. run 2 microservices - gateway & demo microservice: `node --require ts-node/register example/index.ts`
