A Developer's Guide to the Fake API Response Generator

The Fake API Response Generator is a powerful tool for frontend developers and anyone who needs to work with an API that isn't ready yet. It allows you to create realistic, mock API data based on a JSON Schema, powered by the popular Faker.js library.

Features

  • Schema-Driven Generation: Define the structure of your desired data using a standard JSON Schema. The generator uses this schema to create mock data that conforms to your specified types and formats.
  • Realistic Data: Instead of just placeholder text, the tool generates believable fake data (e.g., names, emails, UUIDs, dates) by mapping schema properties and formats to Faker.js functions.
  • Handles Complex Structures: The generator can create nested objects and arrays, giving you a complete and structured mock response.
  • Instant Generation: Get your mock data with a single click.

How to Use

  1. Define Your Schema: In the "JSON Schema" editor, write or paste the schema for the API response you want to mock. You can specify types (string, number, object, etc.) and formats (email, uuid, date-time, etc.).
  2. Generate: Click the "Generate Response" button.
  3. View the Result: The "Generated Response" editor will be populated with a random, fake data object that matches the structure of your schema.
  4. Copy and Use: Use the "Copy Response" button to grab the mock data for use in your application, tests, or UI mockups.
