MobxUtils

This library is mostly unnecessary after the introduction of the rewriter api. It allows scripts to intercept calls to MobX’s observer wrapper, which can be useful for modifying certain UI elements.

Usage

/**
 * @needsLib MobxUtils | https://raw.githubusercontent.com/Gimloader/client-plugins/main/libraries/MobxUtils.js
 */

const MobxUtils = api.lib("MobxUtils");

// Filter for observers being registered with a function including "keyword" in its source code
MobxUtils.interceptObserver("MyScript", (str) => str.includes("keyword"), (func) => {
    // Return a new function that wraps the old function
    const newFunc = function() {
        let res = func.apply(this, arguments);

        // Modify res somehow...
        res.props.children = ["Hello World"];

        return res;
    }

    return newFunc;
});

// Cleanup
api.onStop(() => {
    MobxUtils.stopIntercepts("MyScript");
});
