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

Either add "type": "module" to package.json and convert all require\(\) to ES module import syntax, or use dynamic import\(\) to load the ESM-only package. Alternatively, downgrade to the CommonJS version of the dependency \(e.g., chalk@4 instead of chalk@5\). Root cause: Node.js strictly enforces that ES Modules cannot be loaded via require\(\); packages with "type": "module" or .mjs extensions must be imported.

Journey Context:
You npm install chalk@5 \(or got, node-fetch@3\) and write const chalk = require\('chalk'\). Node immediately throws ERR\_REQUIRE\_ESM. You check the package README and see it is now pure ESM. You try renaming your file to .mjs but then all your other CommonJS dependencies break. You consider downgrading to chalk@4 but want new features. You research Node.js ESM docs and realize you can either refactor the entire project to ES modules by adding "type": "module" to package.json \(changing all requires to imports\), or use const \{default: chalk\} = await import\('chalk'\) as a dynamic import workaround inside an async function.

environment: Node.js 12.20\+, 14.x, 16\+ with ESM-only packages \(chalk 5\+, got 12\+, node-fetch 3\+, strip-json-comments 4\+\) · tags: esm commonjs err_require_esm modules import require node-fetch chalk · source: swarm · provenance: https://nodejs.org/api/esm.html\#require
