[bug\_fix] ERR\_REQUIRE\_ESM require\(\) of ES Module not supported

Convert your project to ESM by adding "type": "module" to package.json and changing require\(\) to import statements, or use dynamic import\(\) \(e.g., const chalk = \(await import\('chalk'\)\).default\) to load the ESM package from a CJS file.

Journey Context:
You npm install chalk@5 \(or node-fetch@3, execa@6\) and try to require it in your index.js. Node crashes with ERR\_REQUIRE\_ESM. You check the package's package.json and see "type": "module". You realize the package is pure ESM. You try changing require to import but get 'SyntaxError: Cannot use import statement outside a module'. You consider downgrading to chalk@4, but want the new features. You read the Node.js ESM docs. You either add "type": "module" to your package.json and rename files to .mjs/adjust imports, or you wrap the require in an async function and use await import\('chalk'\), which works because dynamic import can load ESM.
