# clinical:rules-engine
Rules engines for clinical workflows.
#### Clone the Example Plugin
```bash
cd webapp/packages
git clone https://github.com/clinical-meteor/rules-engine
```
#### Install
```bash
# add your package
meteor add clinical:rules-engine
meteor npm install
```
#### Basic Example
```javascript
import { Engine } from 'json-rules-engine'
import { get } from 'lodash';
/**
* Setup a new engine
*/
let engine = new Engine()
// define a rule for detecting the player has exceeded foul limits. Foul out any player who:
// (has committed 5 fouls AND game is 40 minutes) OR (has committed 6 fouls AND game is 48 minutes)
engine.addRule({
conditions: {
any: [{
all: [Goals.find({'code.text': 'BMI'}).map(function(goal){
return {
fact: 'BMI',
operator: 'lessThan',
value: 24
}
})]
}, {
all: [Goals.find({'code.text': 'Weight'}).map(function(goal){
return {
fact: 'currentWeight',
operator: 'lessThan',
value: 150
}
})]
}]
},
event: { // define the event to fire when the conditions evaluate truthy
resourceType: 'Communication',
status: 'completed'
payload: [{
contentString: "You've met a weight goal!"
}]
}
})
/**
* Define facts the engine will use to evaluate the conditions above.
* Facts may also be loaded asynchronously at runtime; see the advanced example below
*/
let facts = {
currentWeight: get(Observations.find({'code.text': 'Weight'}).fetch()[0], 'valueQuantity.value'),
bodyMassIndex: get(Observations.find({'code.text': 'BMI'}).fetch()[0], 'valueQuantity.value')
}
// Run the engine to evaluate
engine
.run(facts)
.then(events => { // run() returns events with truthy conditions
events.map(event => console.log(get(event, 'payload.contentString')))
})
/*
* Output:
*
* You've met a weight goal!
*/
```
