Usage

This library was created for using in React application uses Redux as store. In actions when data is fetching serialize method passed to convert income data and unserialize method passed to convert outcome data. There is converted data in store and components.

Code Example

Below you can see response body example. There are fields that should have other names in App.

var responseBody = {
  user_id: 1,
  user_name: "Pavel",
  user_avatar: {
    preview_url: "http://site.com/avatar.jpg",
    size: {
      min_width: 100,
      min_height: 100
    }
  },
  user_posts: [{
      post_id: 1, // id
      user_id: 1, // userId
      text: "Hey, how are u?",
      created: new Date(),
    }, {
      post_id: 2,
      user_id: 1,
      text: "Hello! I'm fine",
      created: new Date(),
  }],
};

To change the name of these fields need to create models and use models serialize / unserialize methods

Create Models

User.js

import CSM from 'camelscore-models'
import Avatar from './Avatar'
import Post from './Post'

const User = new CSM({
  fields: {
    'user_id': {
      to: 'id'
    },
    'user_name': {
      to: 'name'
    },
    'user_avatar': {
      to: 'avatar',
      model: Avatar
    },
    'user_posts': {
      to: 'posts',
      model: Post
    },
  }
});

export default User;

Avatar.js

import CSM from 'camelscore-models'

const Avatar = new CSM({
  fields: {
    size: {
      model: {
        'min_width': {
          to: 'width'
        },
        'min_height': {
          to: 'height'
        },
      }
    },
  }
});


export default Avatar;

Post.js

import CSM from 'camelscore-models'

const Post = new CSM({
  fields: {
    'post_id': {
      to: 'id'
    },
    'user_id': {
      to: 'userId'
    },
  }
});


export default Post;

Serialize

To convert data fields to friendly way use model's serialize method

var serialized = User.serialize(responseBody);

returns:

{
  id: 1,
  name: 'Pavel',
  avatar: {
    previewUrl: 'http://site.com/avatar.jpg',
    size: {
      minWidth: 100,
      minHeight: 100
    }
  },
  posts: [{
    id: 1,
    userId: 1,
    text: 'Hey, how are u?'
  }, {
    id: 2,
    userId: 1,
    text: 'Hello! I\'m fine'
  }]
}

Unserialize

to revert data back for passing as body in request use model's unserialize method

var unserialized = User.unserialize(serialized)

returns:

{
  user_id: 1,
  user_name: 'Pavel',
  user_avatar: {
    preview_url: 'http://site.com/avatar.jpg',
    size: {
      min_width: 100,
      min_height: 100
    }
  },
  user_posts: [{
    post_id: 1,
    user_id: 1,
    text: 'Hey, how are u?'
  }, {
    post_id: 2,
    user_id: 1,
    text: 'Hello! I\'m fine'
  }]
}
