JSON Schema Faker Demo

• The json-schema-faker module is used for creating Random JSON data from a given JSON schema.
• This library is really useful for developers and tester during development and testing.
• In this demo,”We will learn to install json-schema-faker and learn its use with a simple example”.
• This json-schema-faker library is build using faker.js, chance.js and randexp.js libraries.
• The json-schema-faker can be installed using npm install json-schema-faker –save-dev command.The following screenshot shows the terminal with json-schema-faker installation.

• To demonstrate the json-schema-faker we have created a JSONSchemaFakerDemo project.The structure of this project looks like following screenshot.

• The my-script.js file contains the code to converting a student schema t0 data.The code content of my-script.js file are as follows:-

var jsf = require('json-schema-faker'),
    aStudentSchema ={
        type: 'object',
        properties: {
            name:{
                type: 'string',
                faker: 'name.findName'
            },
            score:{
                type: 'integer',
                minimum:10,
                maximum:80
            }
        }
    };

var aStudentData = jsf(aStudentSchema);
console.log("aaStudentData: ",aStudentData);

• We can run this demo using node my-script.js command.The following screenshot shows the terminal with the output of this command with generated student data objet.
