ESM-only ESM-only since 5.0.0 — last CommonJS version is 4.1.0

log-symbols dropped its CommonJS build in 5.0.0 (April 2021). The last version with a plain require()-able CommonJS entry is 4.1.0, published Mar 17, 2021; it declares support for Node.js >=10.

On Node.js 20.19+, 22.12+ and newer, require("log-symbols") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. On Node.js 18, which has no require(esm), require("log-symbols") fails with ERR_REQUIRE_ESM.

What to do

  1. On Node.js 20.19+, 22.12+ and newer, require("log-symbols") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26.
  2. From a CommonJS file, use a dynamic import inside an async function: const logSymbols = await import("log-symbols"). That works on every Node.js version the package supports (>=18).
  3. If you need a synchronous require() or run Node.js 18: npm install log-symbols@4.1.0, the last CommonJS release (published Mar 17, 2021); it declares Node.js >=10.
  4. TypeScript: types are bundled; install nothing extra.

How to import log-symbols

ES modules (import)

import * as logSymbols from "log-symbols";

Namespace import shown because the ESM entry may have no default export; use named imports for what it exports.

CommonJS (require)

// Node.js 20.19+, 22.12+ and newer (verified):
const logSymbols = require("log-symbols");

// Any Node.js version the package supports (>=18), from an async function:
async function main() {
  const logSymbols = await import("log-symbols");
}

// Or pin the last CommonJS release (declares Node.js >=10):
// npm install log-symbols@4.1.0

Module format by version

Derived from the type, main and exports fields of every stable release on npm, corrected where a runtime test of that version contradicted them (14 versions; the newest 14 shown).
