apistub

Apistub is a small nodejs module which is used with expressjs to quickly stub out restful api's based on monogosejs schemas that are persisted in a mongo DB. #Features

• Pagination
• Filtering on all properties of return object
• get
• get/:id
• put/:id
• post
• delete/:id

WARNING! This is is not a production module, there are no tests and it is very dirty

#Dependencies

• qs version: 0.6.6
• mongoosejs version 3.8.3 (Non Direct)
• expressjs

#Usage ###Installation

npm install apistub

###Pagination Change perPage and page via query string parameter ex. http://localhost:8000/api/thing?**page=0&perPage=3**

{
  page: 0,
  pages: 1,
  perPage: 3,
  totalItems: 3
}

###Filtering Filter data array via query string parameters ex. http://localhost:8000/api/user?**firstName=Leo&lastName=Bal**. (This is a fuzzy search, pass a strict parameter to get back exact results)

{
  data:[
    {
      firstName:"Leon",
      lastName:"Papazianis",
      age:25
    },
    {
      firstName:"Siyana",
      lastName:"Baleva",
      age:25
    }
  ],
  page: 0,
  pages: 1,
  perPage: 3,
  totalItems: 3
}

###Example Model The following is an example mongoosejs model.

'use strict';
var mongoose = require('mongoose');
var Model = function () {
        var Schema = mongoose.Schema({
            firstName: String,
            lastName: String,
            age: Number
        });
        return mongoose.model('User', Schema);
    };
module.exports = new Model();

###Example Controller There are 5 callbacks, one for each rest method (GET, PUT, POST, DELETE and GET/:id). Choose the callback that fits your route and pass in the model. Pass the callback just before the anonymous function that will handle the response.

• get()
• getByID()
• put()
• post()
• delete()

'use strict';

var modelName = 'user',
    model = require('models/api/'+modelName),
    apistub = require('apistub');
    
module.exports = function (app) {

    app.get('/api/'+modelName,apistub.get(model), function (req, res) {
        res.json(req.apistub);
    });

    app.get('/api/'+modelName+'/:id',apistub.getById(model), function(req, res){
        res.json(req.apistub);
    });

    app.post('/api/'+modelName,apistub.post(model), function(req, res){
        res.json(req.apistub);
    });

    app.put('/api/'+modelName+'/:id',apistub.put(model), function(req, res){
        res.json(req.apistub);
    });

    app.delete('/api/'+modelName+'/:id',apistub.delete(model), function(req, res){
        res.json(req.apistub);
    });
};

#Advanced Usage Using mongoose models enables referencing to different schemas creating relations. In order to populate the paths of a model that are related to different schemas can be achieved either passing a standard mongoosejs populate object, or just passing 'all'. ###Example Student Model The following is an example of a mongoosejs model for students that relate to a classroom.

'use strict';
var mongoose = require('mongoose');
var Model = function () {
        var Schema = mongoose.Schema({
            firstName: String,
            lastName: String,
            age: Number,
            classroom: {
                type:mongoose.Schema.ObjectId,
                ref:'Classroom'
            }
        });
        return mongoose.model('Student', Schema);
    };
module.exports = new Model();

###Example Classroom Model The following is an example of a mongoosejs model for the classroom.

'use strict';
var mongoose = require('mongoose');
var Model = function () {
        var Schema = mongoose.Schema({
            subject: String,
            capacity:Number
        });
        return mongoose.model('Classroom', Schema);
    };
module.exports = new Model();

###Example Controller The following controller is showcasing the usage of a population of a related path.

'use strict';

var modelName = 'student',
    model = require('models/api/'+modelName),
    apistub = require('apistub'),
    populate = [
        {
            path:'classroom',
            select:'subject capacity'
        }
    ];
module.exports = function (app) {
    app.get('/api/'+modelName,apistub.get(model,populate), function (req, res) {
        res.json(req.apistub);
    });
    app.get('/api/'+modelName+'/:id',apistub.getById(model,'all'), function(req, res){
        res.json(req.apistub);
    });
};

Response for the get/ and the get/:id routes. **Tip:**try removing the capacity from the populate object

{
  data:[
   {
    firstName:"Leon",
    lastName:"Papazianis",
    age:27,
    classroom:{
     _id: "53590b87607c3015bd9b0ebe",
     name: "Geography",
     capacity:30,
     __v: 0
    },
   }
  ],
}

Filter by classroom via query string parameter ex. http://localhost:8000/api/student?**classroom=53590b87607c3015bd9b0ebe**.
