dummy-json-js

Description

This is a npm package to create json dummy data.

How to use

Import module

First import the module.

const {Type, generateJSONDummy, generateJSONDummyArray} = require("dummy-json-js")

Define format

To generate json dummy data you need to define the format the data should be. The format contains of the key you want to name the entry, as well as the type of data.

let dummyDataConfig = {
    "stringKey": {"type": Type.String},
    "numberKey": {"type": Type.Number},
    "booleanKey": {"type": Type.Boolean},
    "nullKey": {"type": Type.Null}
}

You can also add explicit configurations to some Types. These options are available:

Type	options name	default-value	example
String	length	10	"length": 123
Number	limit	100	"limit": 200
Integer	limit	100	"limit": 200
Boolean	chance	0.5	"chance": 0.1
StreetNumber	includeLetter	false	"includeLetter": true

Example:

let dummyDataConfigExplicit = {
    "stringKey": {"type": Type.String, "length": 123},
    "numberKey": {"type": Type.Number, "limit": 200},
    "integerKey": {"type": Type.Integer, "limit": 200},
    "booleanKey": {"type": Type.Boolean, "chance": 0.1},
    "streetNumberKey": {"type": Type.StreetNumber, "includeLetter": true}
}

Generate a single json object

To generate a single object use the function generateJSONDummy, and parse the data config object.

const {Type, generateJSONDummy} = require("dummy-json-js")

let dummyDataConfigExplicit = {
    "stringKey": {"type": Type.String, "length": 123},
    "numberKey": {"type": Type.Number, "limit": 200},
    "booleanKey": {"type": Type.Boolean, "chance": 0.1},
    "nullKey": {"type": Type.Null}
}

dummyData = generateJSONDummy(dummyDataConfigExplicit)

Generate a array of json objects

To generate a array of json objects use the function generateJSONDummyArray, and parse the data config object. You can also parse the number of elements the array should contain, default is 2.

const {Type, generateJSONDummyArray} = require("dummy-json-js")

let dummyDataConfigExplicit = {
    "stringKey": {"type": Type.String, "length": 123},
    "numberKey": {"type": Type.Number, "limit": 200},
    "booleanKey": {"type": Type.Boolean, "chance": 0.1},
    "nullKey": {"type": Type.Null}
}

dummyDataArray = generateJSONDummyArray(dummyDataConfigExplicit)
