Tool for generating mock data but valid data comes in handy in app development, where you need to work with databases. Filling in the database by hand is a time-consuming and tedious process. It gets really complicated when you need to create a database with a thousand users. So in this we`ve gathered some useful Javascript tools to create a lot of fake data that makes sense.

json-server

Get a full fake REST API with zero coding in less than 30 seconds (seriously).

faker.js

Generate massive amounts of fake data in the browser and node.js

Mock.js

This is a simulation data generator to help the front-end to develop and prototype separate from the back-end progress and reduce some monotony particularly while writing automated tests.

Easy Mock

This is a persistent service that generates mock data quickly and provids visualization view.

JSON Generator

It has a convenient syntax. You can specify JavaScript any object for template that you see in the left box. Fields may have any name and value, but it must be valid JavaScript. Values, which are strings, may contain one or more template tags. When you click “Save” the template object will be copied several times and random values will be inserted instead of string tags.

json-schema-faker

Use JSON Schema along with fake generators to provide consistent and meaningful fake data for your system.

casual

Fake data generator for javascript.

dyson

When developing client-side applications, often either static JSON files, or an actual server, backend, datastore, or API, is used. Sometimes static files are too static, and sometimes an actual server is not available, not accessible, or too tedious to set up. This is where dyson comes in. Get a full fake server for your application up and running in minutes.

Random User

A free, open-source API for generating random user data. Like Lorem Ipsum, but for people.

fakeJSON

You can use the API for you frontend development, end to end testing, regression testing, rapid prototyping, data generation, and more. A serious mock backend solution for a serious developer. Use the API to iterate, update, and refresh your application for consistent and dependable mock data.
