Node.js Development Fit Snapshot

Prompting Playbook for Node.js

• Specify 'Node.js with ESM' or 'Node.js with CommonJS' to control import/export syntax in generated code
• Mention 'Node.js 20+' or your version to get access to modern APIs like fetch, test runner, and watch mode
• Include 'with TypeScript' for type-safe Node.js code, or 'with JSDoc types' for typed JavaScript without a build step
• When requesting file operations, specify 'with proper error handling and path.join' for cross-platform compatible code
• Ask for 'with graceful shutdown' when building servers to get SIGINT/SIGTERM handlers and connection draining

Patterns AI Should Follow in Node.js

• Stream pipelines with Transform streams for efficient large file processing
• CLI tools with argument parsing, help text, and proper exit codes
• HTTP/HTTPS servers with middleware-like request handling and graceful shutdown
• Worker threads for CPU-intensive operations with message passing and shared buffers
• Event emitter patterns for decoupled component communication in applications
• File system watchers with debouncing for development tools and build systems

CLI Tool with File Processing and Progress

A Node.js CLI script demonstrating file system operations, stream processing, and progress reporting.

#!/usr/bin/env node
import { createReadStream, createWriteStream } from 'node:fs';
import { stat, mkdir } from 'node:fs/promises';
import { join, basename } from 'node:path';
import { Transform } from 'node:stream';
import { pipeline } from 'node:stream/promises';
import { parseArgs } from 'node:util';

const { values } = parseArgs({
  options: {
    input: { type: 'string', short: 'i' },
    output: { type: 'string', short: 'o', default: './output' },
  },
});

if (!values.input) {
  console.error('Usage: process-csv -i <input.csv> [-o <output-dir>]');
  process.exit(1);
}

const { size } = await stat(values.input);
let processed = 0;

const progress = new Transform({
  transform(chunk, encoding, callback) {
    processed += chunk.length;
    const pct = ((processed / size) * 100).toFixed(1);
    process.stderr.write(`\rProcessing: ${pct}%`);
    callback(null, chunk);
  },
});

await mkdir(values.output, { recursive: true });
const outFile = join(values.output, basename(values.input));

try {
  await pipeline(
    createReadStream(values.input),
    progress,
    createWriteStream(outFile)
  );
  console.log(`\nDone: ${outFile}`);
} catch (err) {
  console.error(`\nFailed: ${err.message}`);
  process.exit(1);
}
