Override deps at runtime

🧩 Intercept and override dependencies at build-time with Vite.

A lightweight Vite plugin that lets you replace, extend, or patch libraries (like React, Zustand, etc.) using custom virtual modules — without forking or touching node_modules.

Getting Started

npm install vite-plugin-override-deps -D

or, if using pnpm:

pnpm add vite-plugin-override-deps -D

Usage

Add the plugin to your vite.config.ts:

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import {overrideDeps} from "vite-plugin-override-deps";

export default defineConfig({
  plugins: [
    overrideDeps({
      targets: [
        {
          package: "react",
          overrides: {
            useMemo: (o) => `(...args) => {
              console.log("Custom useMemo!");
              return ${o}.useMemo(...args);
            }`
          }
        }
      ]
    }),
    react(),
  ]
});

Now every import from "react" will be rewritten to a virtual version that exports all React APIs but uses your custom useMemo.

Why

• Patch libraries without forking
• Log or instrument internal behavior
