PHP Wechaty Developing Plan

We already have Wechaty in TypeScript, It will be not too hard to translate the TypeScript(TS) to PHP because wechaty has only 3,000 lines of the TS code, they are well designed and de-coupled by the wechaty-puppet abstraction. So after we have translated those 3,000 lines of TypeScript code, we will almost be done.

As we have already a ecosystem of Wechaty in TypeScript, so we will not have to implement everything in PHP, especially, in the Feb 2020, we have finished the @chatie/grpc service abstracting module with the wechaty-puppet-service implmentation.

The following diagram shows out that we can reuse almost everything in TypeScript, and what we need to do is only the block located at the top right of the diagram: Wechaty (PHP).

Example: How to Translate TypeScript to PHP

There’s a 100 lines class named Image in charge of downloading the WeChat image to different sizes.

It is a great example for demonstrating how do we translate the TypeScript to PHP in Wechaty Way:

Image Class Source Code

• TypeScript: https://github.com/wechaty/wechaty/blob/master/src/user/image.ts
• PHP: https://github.com/wechaty/php-wechaty/blob/master/wechaty/IO/Github/Wechaty/User/Image.php

If you are interested in the translation and want to look at how it works, it will be a good start from reading and comparing those two Image class files in TypeScript and PHP at the same time.
