We're going to leave this server running and not touch it again for the duration
of the workshop, so **don't close it** until the workshop is over!

# ![RealWorld Example App](rw-logo.png)
> ### [Moleculer](http://moleculer.services/) codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the [RealWorld](https://github.com/gothinkster/realworld) spec and API.
This repo is functionality complete — PRs and issues welcome!
**Live demo on Glitch: https://realworld-moleculer.glitch.me**
Glitch project: https://glitch.com/edit/#!/realworld-moleculer
*[React + Redux](https://github.com/icebob/react-redux-realworld-example-app) front-end UI is included.*
*For more information on how to this works with other frontends/backends, head over to the [RealWorld](https://github.com/gothinkster/realworld) repo.*
## Getting started
### To get the Node server running locally:
- Clone this repo
- `npm install` to install all required dependencies
- `npm run dev` to start the local server
- the API is available at http://localhost:3000/api
Alternately, to quickly try out this repo in the cloud, you can
[![Remix on Glitch](https://cdn.glitch.com/2703baf2-b643-4da7-ab91-7ee2a2d00b5b%2Fremix-button.svg)](https://glitch.com/edit/#!/remix/realworld-moleculer)
#### MongoDB persistent store
Basically the services stores data in an NeDB persistent file storage in the `./data` folder. If you have to use MongoDB, set the `MONGO_URI` environment variable.
```
MONGO_URI=mongodb://localhost/conduit
```
#### Multiple instances
You can run multiple instances of services. In this case you need to use a transporter i.e.: [NATS](https://nats.io). NATS is a lightweight & fast message broker. Download it and start with `gnatsd` command. After it started, set the `TRANSPORTER` env variable and start services.
```
TRANSPORTER=nats://localhost:4222
```
### To get the Node server running locally with Docker
1. Checkout the repo `git clone https://github.com/ice-services/moleculer-realworld-example-app.git`
2. `cd moleculer-realworld-example-app`
3. Start with docker-compose: `docker-compose up -d`
It starts all services in separated containers, a NATS server for communication, a MongoDB server for database and a [Traefik](https://traefik.io/) reverse proxy
4. Open the http://docker-ip:3000
5. Scale up services
`docker-compose scale api=3 articles=2 users=2 comments=2 follows=2 favorites=2`
