# CodeMod Toolkit

CodeMod Toolkit is a powerful utility designed to streamline file modifications in JavaScript and TypeScript projects. Whether you're rewriting import statements, modifying JSON configuration files, or transforming TypeScript files, this toolkit offers a comprehensive API to apply changes efficiently. With support for multiple runtimes (Node.js, Deno, browsers, etc.), it provides flexibility across environments and ensures compatibility with modern ecosystems.

Features

• Flexible File Patching: Modify text, JSON, and TypeScript files with ease.
• Cross-Runtime Compatibility: Works in Node.js, Deno, and browser environments.
• TypeScript Support: Use the ts-morph library to safely modify TypeScript files.
• Contextual File System Operations: Integrated file system helpers to manage file changes.
• Custom CodeMod Context: Use a context-aware API to add custom operations and patches.

Usage

import { codeMod, rewriteImports } from "@deco/codemod-toolkit";

const symbolMap = {
  "old-module": {
    "oldExport": {
      moduleSpecifier: "new-module",
    },
  },
};

await codeMod({
  name: "Rewrite Imports",
  description: "Rewrites import statements based on a symbol map",
  targets: [rewriteImports(symbolMap)],
});
