Querybuilder have a simple, mongo like, API to create SQL and NoSQL queries.
Install
$ npm install querybuilder
Supported storages / client libs
- MongoDB (Tested with node-mongodb-native)
- MySQL (Tested with node-mysql)
API
Create NoSQL query (MongoDB)
var Querybuilder = require('querybuilder');
var qb = new Querybuilder('mongodb');
// Synchronous
var query = qb.select('*')
.where({name: 'horst'})
.offset(5)
.call();
/* <- returns:
{ type: 'select',
what: undefined,
where: { name: 'horst' },
limit: 50,
skip: 5,
sort: {},
set: {} }
*/
// Asynchronous
// Define a handler. We simply forward the query to the callback
qb.handler(function(query, callback) {
// Your SQL connection can be placed here
callback(null, query);
});
qb.select('*')
.from('users') // just for campability to mysql
.where({name: 'horst'})
.offset(5)
.call(function(err, query) {
if (err) throw new Error(err);
console.dir(query);
// <- equal to synchronous
});
Create SQL query (MySQL)
var Querybuilder = require('querybuilder');
var qb = new Querybuilder('mysql');
// Synchronous
var query = qb.select('*')
.from('users')
.where({name: 'horst'})
.offset(5)
.call();
// <- returns: 'SELECT * FROM `users` WHERE (`name` = \'horst\') LIMIT 50,5'
// Asynchronous
// Define a handler. We simply forward the query to the callback
qb.handler(function(query, callback) {
// Your SQL connection can be placed here
callback(null, query);
});
qb.select('*')
.from('users')
.where({name: 'horst'})
.offset(5)
.call(function(err, query) {
if (err) throw new Error(err);
console.dir(query);
// <- equal to synchronous
});
