Mosc.js (A simple inline object model builder)
Mosc.js is a simple inline object model builder for NodeJS (A small port exists for client-side javascript). It can be used to build ORM schemas, app configurations and a host of other valid object usecases.
Don't like those pesky curly braces? Just:
npm install Mosc --save
var Mosc = require('mosc');
var mosc = new Mosc({});
var SimpleORMUserModel = mosc.build('title:string')
.build('name:string')
.build('age:integer')
.end();
SimpleORMUserModel
above becomes:
{
title:"string",
name:"string",
age:"integer"
}
Pass in a context dictionary
You can pass a context dictionary argument for Mosc to use when evaluating certain placeholders in your build arguments
var context_dictionary = {'SEQ':{string:'SEQUELIZE_STRING'}};
var result = new mosc(context_dictionary)
.build('id', 'type:*SEQ*.string')
.end();
/*
*SEQ*.string is evaluated using the context dictionary passed
Mosc looks for the property SEQ in the context dictionary,
it then checks if there is a corresponding string property
if there is, Mosq evaluates SEQ.string and returns the result hence:
result = {
id: {
type:'SEQUELIZE_STRING'
}
}
if there isn't MOSC throws a context not found in eval dict error
*/
With Mosc, it is also possible to do depth builds i.e object in object in object:
var obj = mosc.buildIn('attributes.id');
/*
obj = {
attributes:
{
id:
{
}
}
}
*/
var obj = mosc.buildIn('attributes.id', 'type:String, primaryKey:true').end();
/*
obj = {
attributes:
{
id:
{
type:'String',
primaryKey:true
}
}
}
*/
(For depth builds, the final path in the depth must be a valid object i.e 'attributes.id', id, if it exists, must be an object otherwise Mosc throws a 'Path must be an object error')
