Powerfull JSON Generator
Quick Example
Try out the following code and realise the power of Swoody ๐
import { generate } from 'swoody'
const eventsSchema = {
repeat: 7,
object: {
id: '{{ faker.random.uuid() }}',
isOnline: '{{ faker.random.boolean() }}',
description: '{{ faker.lorem.paragraphs(2) }}',
when: '{{ moment() }}',
place({ faker }) {
const cities = ['New-York', 'Moscow', 'Tokyo']
return faker.random.arrayElement(cities)
},
organizators: {
repeat: [1, 5],
object: {
name: '{{ faker.name.firstName() }} {{ faker.name.lastName() }}',
job: '{{ faker.name.jobTitle() }}',
email: '{{ faker.internet.email() }}',
avatar: '{{ faker.internet.avatar() }}',
age: '{{ 10 + 8 }}',
},
},
},
}
const json = generate(eventsSchema) // random generated json data
console.log(json)
Documentation
Arrays
object
field is using for defining value of element of array
repeat
field is using for defining exact or ramdom in range length of array:
This will generate array of exact length
const schema = {
repeat: 7, // exact length
object: '{{ faker.random.number() }}',
}
This will generate array of random length in range from 1 to 5
const schema = {
repeat: [2, 8], // ramdom in range from 2 to 8
object: '{{ faker.random.number() }}',
}
Static values
To get a static values just pass them and left alone (-_-):
const schema = {
str: 'some string',
num: 1923,
nil: null,
bool: false,
parent: {
isChild: true
child: {
otherNestedProp: 'kek'
}
}
}
And exceptions...
All the following values below will be evaluated to null
const schema = {
prop0: null,
prop1: undefined,
prop2: NaN,
prop3: Infinity,
prop4: -Infinity,
prop5: () => console.log,
prop6() {},
}
Special schema
values
evaluating function props
This function value will be evaluated to returned value from return
statement:
const schema = {
funcProp(context) {
return 20 % faker.random.number()
},
}
And function which return nothing will be evaluated to null
:
const schema = {
funcProp(context) {
console.log(context)
},
}
evaluating string and mustaches props
Any expresion inside mustaches {{ }}
will be evaluated and returned in field.
This will evaluate expression inside mustache:
const schema = {
num: '{{ faker.random.number() }}',
string: 'number: {{ 2 + 4 }}',
}
You also have a context
in mustaches and mustaches
const schema = {
mustacheContext: '{{ faker.random.number() }}',
functionContext(context) {
return context.faker.random.number()
},
}
Build in context
Soon...
Custom Context
You can pass your own context
as a second argument in generate
and handleField
:
import { generate, handleField } from 'swoody'
const customContext = {
MATH_PI: 3.14159,
cities: ['New-York', 'Moscow', 'Tokyo'],
trimString(string) {
return string.trim()
},
}
const schema = {
repeat: 7,
object: {
radius: '{{ MATH_PI * 2 }}',
place(context) {
return context.faker.random.arrayElement(context.cities)
},
str(context) {
return context.trimString(' fdkasfj ')
},
},
}
// pass customContext
const jsObject = handleField(eventsSchema, customContext)
const jsonData = generate(eventsSchema, customContext)
console.log(jsObject)
console.log(jsonData)
