[bug\_fix] Error \[ERR\_REQUIRE\_ESM\]: require\(\) of ES Module

Convert require\(\) to dynamic import\(\): const module = await import\('module-name'\); Or if controlling the package, rename file to .mjs or add 'type': 'module' to package.json to enable ESM throughout.

Journey Context:
You npm install a modern package \(like chalk 5\+, node-fetch 3\+, or got\) and try to require it in your CommonJS app: const chalk = require\('chalk'\). You immediately get ERR\_REQUIRE\_ESM. You check the package docs and see it's now 'ESM-only'. You try changing file extension to .mjs but then all your other require\(\) calls break. You consider using .cjs extension for old files, but that creates a mess. After reading the Node.js ESM documentation, you realize you can keep your file as .js \(CommonJS\) but use dynamic import\(\) which returns a Promise to load ESM modules. This allows gradual migration without rewriting everything.

environment: Node.js 12.20\+, 14\+, or 16\+ with modern ESM-only packages \(chalk 5\+, node-fetch 3\+, got 12\+, etc.\) · tags: esm commonjs err_require_esm dynamic-import module-interop esm-only · source: swarm · provenance: https://nodejs.org/api/esm.html\#require and https://nodejs.org/api/esm.html\#interoperability-with-commonjs
