#querybuilder-rules
A subset of the jQuery QueryBuilder library, modified to work in a node.js environment. This module allows you to convert the rules object that's generated by the jQuery QueryBuilder UI into the native query language for various database engines.
##Supported Databases
- SQL
- MongoDB
##Example
//an example of a rules object that's generated by the jQuery QueryBuilder UI.
var rules = {
"condition": "AND",
"rules": [
{
"id": "name",
"field": "name",
"type": "string",
"input": "text",
"operator": "equal",
"value": "Sh"
}
]
}
//load this module
var QueryBuilder = require('querybuilder-rules');
//create a new instance variable
var qb = new QueryBuilder();
//generate a SQL Where statement
console.log(qb.getSQL(false, false, rules).sql);
//generate mongoDB find parameter
console.log(db.getMongo(rules));###Methods
