Modern Node 24+ idioms and dependency selection - pure ESM, node: builtins, top-level await, structuredClone, AbortController. Use when writing or refactoring any Node code, or when adding, auditing, or upgrading a dependency in package.json. Triggers on require, module.exports, __dirname, import.meta, node: prefixed imports, JSON.parse(JSON.stringify()), fetch timeouts, AbortSignal, and any package.json dependency change.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Node Idioms

**The Node 24+ baseline every file is written to, and how a dependency earns a line in `package.json`.**

The version is pinned in `.node-version` and declared as `"engines": { "node": ">=24" }`. Development and tests run on real Node with no transpiler and no bundler, so a current standard-library helper is always available.

## Pure ESM

`package.json` sets `"type": "module"`. `import` and `export` are the only module syntax; `require`, `module.exports`, `__dirname`, and `__filename` do not appear.

```js
import { createServer } from 'node:http';
import { readFile } from 'node:fs/promises';

export function makeRouter(routes) {
  return (req, res) => { /* ... */ };
}
```

A module's own directory comes from `import.meta`, which Node 24 exposes directly:

```js
const here = import.meta.dirname;
```

The longer `dirname(fileURLToPath(import.meta.url))` form is only needed when supporting a runtime older than this baseline, which nothing here does.

## Top-Level Await

How to install

The exact contents, by fingerprint
mdr add tanq16/claudex/node-idioms@sha256:3d264d5bed213311

The line at the top of this page pins the label git:20260819.70031cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
