RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including options-checker. Try it out:
/**
* Created by brugnara on 11/10/18,
* @ daniele@brugnara.me
*/
const optionsChecker = require('options-checker')
const neededOptions = {
action: ['addE', 'addV', 'drop'],
name: true,
_if: {
action: {
'addE': {
name: false,
fromName: true,
toName: true
}
}
}
}
// valid: true
console.log(optionsChecker({
action: 'addE',
fromName: 'start',
toName: 'end'
}, neededOptions))
// valid: false, option: name
console.log(optionsChecker({
action: 'addV'
}, neededOptions))
// valid: false, option: action, validOptions: ['addE', 'addV', 'drop']
console.log(optionsChecker({
action: 'junk',
name: 'junk2'
}, neededOptions))
const field = Math.random()
console.log(optionsChecker({
field,
action: 'test'
}, {
action: true,
field (value, key) {
return value === field && key === 'field'
}
}))
