Appwrite SDK Generator

WORK IN PROGRESS - NOT READY FOR USAGE

Appwrite SDK generator is a PHP library for auto generating SDK library for multiple languages or platforms.

The SDK uses predefined language settings and Twig templates to generate code base on different API specs.

Currently the only spec supported is Swagger 2.0, but we intend to add support for more specification in the near future.

Examples

You can view examples of generated code libraries in the examples directory.

Getting Started

Install using composer:

composer require appwrite/sdk-generator

Create language and SDK instances and generate code to target directory.

<?php

require_once 'vendor/autoload.php';

use Appwrite\Spec\Swagger2;
use Appwrite\SDK\SDK;
use Appwrite\SDK\Language\PHP;

// Read API specification file (Swagger 2) anc create spec instance
$spec = new Swagger2(file_get_contents('https://appwrite.io/v1/open-api-2.json?extension=1'));

// Create language instance
$lang = new PHP();

$lang // Set language or platform specific options
    ->setComposerPackage('my-api')
    ->setComposerVendor('my-company')
;

// Create the SDK object with the language and spec instances
$sdk  = new SDK($lang, $spec);

$sdk
    ->setLogo('https://appwrite.io/v1/images/console.png')
    ->setLicenseContent('License content here.')
    ->setVersion('v1.1.0')
;

$sdk->generate(__DIR__ . '/examples/php'); // Generate source code

TODO List

• Better spec modeling
• Spec Validators
• XML Content Types

SDK Checklist

It is very important for us to create consistent structure, architecture and native like feel for the SDKs we generate. In order to accomplish that we have made a checklist of points to support while adding a new language to the SDK generator.

The checklist aims to balance consistency among languages, and follow each platform's best practices and coding standards.

• Proper Coding Standards and Conventions
• Proper Skeleton Structure
• Readme Doc
• HTTP Client class or object
  • Client Setters
    • Set Auth Keys Method
    • Set Basic Auth Method
    • Set OAuth Dialog Method
    • Set Endpoint Method
    • Set Self Signed Certificates
  • Default Headers
    • 'appwrite-sdk-version' header
    • Add 'User-Agent' header with server name and language version (ubuntu-18.02:php-7.0.1)
  • Methods
    • addHeader(key, value)
    • call(method, path = '', headers = [], params = [])
      • Concat GET params to path
      • Parse request params by content type header
      • Parse response params by content type header
      • Throw error on bad response
• Service Abstraction (optional)
  • Constructor receiving an instance of the client class
• Service Class
  • Headers Support (Content Type)
  • Parameters Support
    • Default Values Support
    • Required Values Support
    • String Support
    • Integer Support
    • Boolean Support
    • Files Support (+array file and multiple header support and params flatten)
    • Arrays / Dictionaries / Lists Support (+concatenation type)
• Usage Example Docs
• Definitions / Models Classes - with setters and getters
