TTPatch is a lightweight thermal update framework

The principle of

Dynamic call/replace/new method /Class based on JavaScript+ Runtime

background

Because the old company 58 version iteration block, many requirements, resulting in a lot of requirements development quality and testing quality is not high. There are a lot of little bugs on the line that can be a headache. So there’s a thermal repair wheel.

Mature solutions for the industry

The following is a list of some personal understanding, not comprehensive, please understand.

  1. lua.
  2. JavaScript.
  3. OcAs script, Didi solution (open source).

Hot updates are well established in game development, and the idea is similar regardless of how they are implemented.

The Object C Code is converted into an intermediate language and delivered, and then executed locally. The intermediate language achieves the purpose of dynamic invocation through the dynamic implementation of Object C.

As a technical selection, JavaScript is chosen as the intermediate language because it is developed by RN in 58.

See here a lot of students will ask, excuse me you withJSPatchWhat’s the difference?

The principle is that JavaScript is implemented as an intermediate language, but the technical details are different. Some take a cue from JSPatch.

whyJSPatchYou can’t stand trial. YourTTPatchCan you get a trial?

First of all, the open source version of JSPatchgithub has been removed from the shelves, and apps that integrate the open source version have almost never been approved. But a paid version is still available. This shows that the hot update method with JavaScript as the intermediate language itself is not blocked. And I understand that many large factories also integrate hot update modules. So hot updates don’t work because of JSPatch itself. For details, see the review terms for rejected hot updates.

On the shelves

At present, several apps have been successfully launched with TTPatch integration.
