    OS and Browser Compatibility


    • 100 mock employees, with names, addresses, phone numbers, etc.
    • 100 mock projects, with names, dates, departments, employees assigned, etc.
    • Full-size and thumbnail photos for each employee
    • No dependencies
    • Tested in Node.js and all modern web browsers on Mac, Windows, and Linux
    • All data follows logical rules:
      • Usernames, SSNs, addresses, etc. are unique
      • Birthdates, hire dates, and termination dates are in proper chronological order
      • Employee roles "make sense" (e.g. "full time" and "part time" are mutually exclusive)
      • Employees are only assigned to projects in their own department
      • Employees are only assigned to projects that occurred during their employment


    Install using NPM or Yarn:

    npm install @jsdevtools/static-mock-data


    The mock data can be used as plain JSON or as JavaScript objects.

    Raw JSON

    const employees = require("@jsdevtools/static-mock-data/employees.json");
    for (let employee of employees) {
      console.log(employee.dob);        // date string
      console.log(employee.portrait);   // relative file path

    JavaScript Objects

    const mockData = require("@jsdevtools/static-mock-data");
    for (let employee of mockData.employees) {
      console.log(employee.dob);        // Date object
      console.log(employee.portrait);   // absolute file path

    Browser support

    Static Mock Data supports recent versions of every major web browser. Older browsers may require Babel and/or polyfills.

    To use Static Mock Data in a browser, you'll need to use a bundling tool such as Webpack, Rollup, Parcel, or Browserify. Some bundlers may require a bit of configuration, such as setting browser: true in rollup-plugin-resolve.
