ANT

Description

It is a small, secure and fast ORM for indexedDB. Created for projects who needed to encapsule their Object Stores into models and a readable API for comunication with the DB.

It is using Web Workers for isolate de access to DB from the default thread. Look at the articles in the bottom of this document and see why it's good to your project.

Instalation

Just run:

$ npm i --save ant-orm

If you aren't using npm and prefer import, junt download in the dist folder the ANT.js file and place into your HTML like this:

<script src="/path/to/ANT.js"></script>

Than you can copy the workers folder and import to your project.

How to build

For building this projet is simples:

$ npm run build

Usage

Initialization

ANT.init({
    databaseName: "DATABASE NAME",
    workersPath: "/path/to/workers",
    version: 1, //version of DB
    modelsPaths: {
        User: "/models/users.js" //Name of your model and path to your model
    }
});

Defining Model

Just create a js file:

class User extends ANT.Model {
    get columns(){
        return this.setColumns({
            id: { type: ANT.TYPES.NUMBER, unique: true },
            name: { type: ANT.TYPES.STRING },
            active: { type: ANT.TYPES.BOOL, defaultValue: true }
        });
    }
}

TYPES

    const number = ANT.TYPES.NUMBER;
    const string = ANT.TYPES.STRING;
    const boolean = ANT.TYPES.BOOL;
    const date = ANT.TYPES.DATE;

Bulk a Model

    let user = new Ant.User({
        id: 1,
        name: "Ricardo Zorzal"
    })

Persisting a Model

    let user = new Ant.User({
        id: 1,
        name: "Ricardo Zorzal"
    });

    await user.persist();

Creating a Model

    let user = await Ant.User.create({
        id: 1,
        name: "Ricardo Zorzal"
    })

Updating a Model

    let user = await Ant.User.create({
        id: 1,
        name: "Ricardo Zorzal"
    });

    user = await user.update({
        name: "Ricardo Zorzal Davila"
    });

Destroying a Model

    let user = await Ant.User.create({
        id: 1,
        name: "Ricardo Zorzal"
    });

    await user.destroy();

Query

Simple Query

    let users = await Ant.User.findAll({
        name: "Ricardo Zorzal"
    });

Operators

    let users = await Ant.User.findAll({
        name: {
            "$eq": "equals",
            "$ne": "not equals",
            "$gt": "greater than",
            "$gte": "greater than equals",
            "$lt": "less than",
            "$lte": "less than equals",
            "$btw": "between",
            "$btwe": "between equals",
            "$in": "IN",
            "$like": "LIKE",
            "$notLike": "NOT LIKE"
        }
    });
