Generate generic validators and models
$ npm install [--save-dev] @helpdotcom/help-gen
A prop represents a base configuration object for a single property that is intended to be used by a validator or a model.
All properties are required unless optional()
or required(false)
is called.
Returns a Prop that represents an <Array>
.
Example:
'use strict'
const {Prop} = require('@helpdotcom/help-gen')
// Support validating primitives in arrays
Prop
.array()
.path('department_names')
.required(false)
.example([
'General'
])
.props(Prop.string())
.description('Contains the department names')

ThetoJSON()
of aProp
Returns a Prop
based on config.type
.
config
[<Config>
] Adoc.json
validator config object
Returns an array of Prop
objects based on the type
.
Note: This method is intended strictly for converting doc.json
validator
trees back into Prop trees.

is an instance of a NanoProp

This will generate one-off generic validators.
This will generate a set of models that are able to reference each other.
Every model must have a model config. A model config will look something like the following:
{ name: 'VisitorJoin'
, type: 'visitor_join'
, includeType: true
, props: [
Prop.date().path('created_at')
, Prop.ref('Visitor').path('visitor')
]
}
Example:
'use strict'
const Manager = require('@helpdotcom/nano-model')
const manager = new Manager({
configs: [
{ name: 'Visitor'
, type: 'visitor'
, props: [
{ name: 'Visitor'
, type: 'visitor'
, props: [
Prop.uuid().path('id')
, Prop.string().path('name')
]
}
, { name: 'VisitorJoin'
, type: 'visitor_join'
, includeType: true
, props: [
Prop.date().path('created_at')
, Prop.ref('Visitor').path('visitor').optional()
]
}
]
}
]
})
const out = manager.generate()
// To write all of the models, one can do something like this:
const fs = require('fs')
const path = require('path')
const MODELS_DIR = path.join(process.cwd(), 'models')
for (const item of out.values()) {
const fp = path.join(MODELS_DIR, item.filename)
fs.writeFileSync(fp, item.code, 'utf8')
}
conf
<Object>
A single model config
Returns a <Map>
where the key is the model name and the value is an
object like:
{ code: '' // Will be the actual code
, filename: 'visitor.js' // Will be the filename (does not include the path)
}
