## Light-orm
Light-orm - simple ORM node.js wrapper for relational databases. It does not depends on any specific driver, so you can connect to mysql, postgresql, ms server with your favorite driver.
Your db connector (or wrapper) just should implement the interface:
```
interface DriverInterface {
query(query: string, handler: (err, rows, fields) => void);
}
```
This interface came from node-mysql driver, as most popular option, that lets you avoid writting your wrappers to connectors.
Light-orm gives you freedom in choising your own driver. You should not any more make meet half-way between high driver performance with native realization and ORM wrapper.
### Installation
`npm install light-orm`
### Development
Light-orm is written on typescript. Look for the sources here: lib/typescript and lib/compiler. You may find there comments in jsdoc style.
### Examples
Example connection (mysql):
```javascript
var mysql = require('mysql'),
lightOrm = require('light-orm');
lightOrm.driver = mysql.createConnection(require('./connection.json'));
lightOrm.driver.connect();
```
Create collection for table name `author`:
```javascript
var AuthorCollection = new lightOrm.Collection('author');
```
Find one model:
```javascript
AuthorCollection.findOne({
id: 1
}, function(err, model) {
console.log(model.getAll());
//{ id: 1, name: 'James Bond', description: 'Agent 007' }
});
```
Find one model by sql:
```javascript
AuthorCollection.findOne("SELECT * FROM `author` WHERE id = 1", function(err, model) {
console.log(model.getAll());
//{ id: 1, name: 'James Bond', description: 'Agent 007' }
});
```
Find models:
```javascript
CarCollection.find({
category_id: 5
}, function(err, models) {});
```
Find models by sql:
```javascript
CarCollection.find({
category_id: 5
}, function(err, models) {});
```
Get all attributes:
```javascript
model.getAll();
```
Get one attribute:
```javascript
model.get('name');
```
Set attribute:
```javascript
model.set('name', 'Oleksandr Knyga');
```
Set attributes:
```javascript
model.set({
name: 'Oleksandr Knyga'
});
```
Check attribute:
```javascript
model.has('name');
```
Clear attributes:
```javascript
model.clear();
```
Clear one attribute:
```javascript
model.clear('name');
```
Get custom row by sql:
```javascript
AuthorCollection.findOne("SELECT COUNT(*) as `count` FROM `author` WHERE name = '" + author.name + "'", function(err, data) {
var count = data.get('count');
});
```
Save:
```javascript
model.create(function(err, model) {});
```
Update:
```javascript
model.update(function(err, model) {});
```
Update, with custom where block:
```javascript
model.update({
pkValue: {
id: 31
}
}, function(err, model) {});
```
Update, manual pk field name:
```javascript
model.update({
pk: ['id']
}, function(err, model) {});
```
Delete:
```javascript
model.remove(function(err, model) {});
```
Delete, with custom where block:
```javascript
model.remove({
pkValue: {
id: 31
}
}, function(err, model) {});
```
Delete, manual pk field name:
```javascript
model.remove({
pk: ['id']
}, function(err, model) {});
```
If you do not want to have model in callback, add `false` as last argument to remove, update, create. Like this:
```javascript
model.update({
pkValue: {
id: 31
}
}, function(err, model) {}, false);
```
