phly/sqlite-resource

Library for persisting JSON resources in SQLite

Phly\SqliteResource

This is a "toy" library designed to make it easy to prototype persistence for RESTful APIs. It essentially allows you to create a SQLite database with the following columns:, _(*1)

• id, which represents an identifier. This is autogenerated by the library, and will be a 32 character hexidecimal string (i.e. characters 0-9 and a-f).
• data, a JSON-encoded string representing a resource. This will always be returned as an associative array.

Installation

The easiest way to install is via Composer. Download the composer installer, and create a composer.json file as follows:, _(*2)

{
    "minimum-stability": "dev",
    "require": {
        "phly/sqlite-resource": "dev-master"
    }
}

Then run composer install., _(*3)

Schema

A schema is available in schema.sqlite.sql. Essentially:, _(*4)

CREATE TABLE IF NOT EXISTS collection (
    id CHARACTER(32) PRIMARY KEY,
    data BLOB NOT NULL
);

Alter it as you see fit to change the table name., _(*5)

Initialization

In order to instantiate Phly\SqliteResource\SqliteResource, you will need an instance of PDO. Typical instantiation will look like this:, _(*6)

use PDO;
use Phly\SqliteResource\SqliteResource;

$pdo = new PDO('sqlite:/path/to/database.db');
$resource = new SqliteResource($pdo, 'table-name');

API

The API supports the following operations:, _(*7)

• create(array $data) - Inserts the resource into the database and returns it, with a new "id" key with the newly created identifier.
• fetch($id) - Fetches the resource with the given identifier. If no resource is found, an exception is thrown.
• fetchAll($limit = null, $offset = null) - Fetches all resources from the database, returning an array of arrays. If a limit is given, returns only the number of resources indicated; if an offset is given along with a limit, returns resources from that offset
• patch($id, array $data) - Merges the provided $data with the record that already exists in the database identified by $id and saves it. The merged resource is returned.
• update($id, array $data) - Replaces the resource identified by $id with the $data. Returns the resource.
• delete($id) - Deletes the resource identified by $id.

Caveats

Do not use this in production. Use a document database, or a relational database with a real schema that maps to the fields in your resources., _(*8)
