Emulator

A simple server for emulating an API.

Install through npm:

npm install -g emulator

Usage

API response simulation

Emulator is a simple server that allows for rapid prototyping of client-side applications.

Make any request:

http://localhost:3000/profile?user=me

$.ajax('http://localhost:3000/profile', {
  data: {user: 'me'}
});

And get the same response data:

{user: 'me'}

Or specify a different response:

http://localhost:3000/profile?user=me&response[user]=you

$.ajax('http://localhost:3000/profile', {
  data: {
    user: 'me',
    response: {
      user: 'you'
    }
  }
});

And get the response you specified:

{user: 'you'}

Other routes

Emulator also includes other helper routes that may be useful in your application.

Redirects

Redirect to a different url:

http://localhost:3000/redirect/me

http://localhost:3000/redirect?redirect=me

These routes both redirect to http://localhost:3000/me

Simulate high latentcy or long response times

Force the server to simulate long response times:

http://localhost:3000/wait/4000?user=me

This request would wait 4 seconds and then respond with:

{user: me}

Test error codes

Test how your application would respond to error codes:

http://localhost:3000/500

http://localhost:3000/404

Responds with a 500 (Internal Server Error) code and a 404 (Not Found) code, respectively
