Faux call

Simple mock server for your convenience and testing!

Disclaimer

This is still under development, which means that the API and functionality might change.

How it works

Faux creates a VERY simple mocked database which is thrown out once the server is shut down.

Install

yarn add -D faux-call
// or
npm install --save-dev faux-call

Usage

Create a server file which will initialize Faux-call:

// ./path/to/faux.server.js
 
// Import Faux
const faux = require('faux-call');
 
// Import Models
const UserModel = require('./path/to/UserModel');
 
// Register API
faux.register(UserModel);
 
// Set API namespace
// localhost:3000/api/users
faux.config.set('api.namespace', '/api');
 
// Set auth namespace
// localhost:3000/auth/login
// localhost:3000/auth/logout
// localhost:3000/auth/register
faux.config.set('auth.namespace', '/auth');
 
// Defining custom route
faux.route.get('/my/custom/route', (res, req) => {
  return res.send('my custom response');
});
 
// Start faux
faux.start(3000);

Once your configuration is ready, use node to run it:

node ./path/to/faux.server.js

Accepted routes

• GET => /route: Get all rows from database
• POST => /route: Stores a new row on the database
• GET => /route/:id: Gets the row with a specific id
• PUT|PATCH => /route/:id: Updates a row with a specific id
• DELETE => /route/:id: Deletes a row with a specific id

Attribute routes

If attributeRoutes is activated on the model, Faux will generate route attributes for you to get and patch data:

• GET => /route/:id/:attribute: Gets a specific attribute from a row with a specific id
• PATCH => /route/:id/:attribute: Updates a specific attribute from a row with a specific id

If you wish to ignore certain attributes (such as passwords), you can declare a protected array containing the ignored column names.

Relationship routes

If relationshipRoutes is activated on the model, Faux will generate route for you to view, add, modify and delete relationship data:

• GET => /route/:id/relationship: Lists all related rows
• POST => /route/:id/relationship: Adds a new row to the model
• PATCH => /route/:id/relationship/:relationship_id: Updates a related model
• DELETE => /route/:id/relationship/:relationship_id: Deletes a related model

Mocking the not so happy path

When testing your application, there will be times where you need to test failed states and responses. On these cases, Faux allows you to mock the status and response messages. To do so, just add a status and a JSON response string header to your request. For instance:

post('http://localhost:3000/users', data, {
    headers: {
      status: 500,
      response: '{"message": "E-mail field must be unique."}'
    }
});

Model example

// ./path/to/UserModel.js
const UserModel = {
  // Name of the model (is required)
  // String
  name: 'User',
  // Model's route base (is required)
  // String
  route: '/users',
  // Database columns (is required)
  // Array [(Column)<Strings>]
  columns: ['name', 'email', 'password'],
