A mock server generated from your API Blueprint.


API-Mock is a node.js npm module that generates a mock server (express) from your API specification. Document your API in the API blueprint format, and API-Mock mocks your routes and sends the responses defined in the api spec.


API-Mock requires node.js, and npm.

npm install -g api-mock

If you wish to install from source, you will need to build the library files manually (only the CoffeeScript source is committed to the repository). To do this, simply run:



npm build

  --port, -p          Set which port api-mock should listen on.
