Next Steps for chroncraft

Congratulations! chroncraft has been successfully generated. Here's what to do next:

1. Install Dependencies

npm install

This will install all development dependencies including:

  • TypeScript 5.3+
  • tsup (bundler)
  • Vitest (test runner)
  • ESLint & Prettier
  • size-limit
  • tinybench (for benchmarks)

2. Build the Project

npm run build

This will:

  • Compile TypeScript to JavaScript
  • Generate ES modules (.mjs) and CommonJS (.js)
  • Create TypeScript declaration files (.d.ts)
  • Minify the output
  • Enable tree-shaking optimizations

Expected output in dist/:

  • index.mjs / index.js - Core module
  • format.mjs / format.js - Format module
  • parse.mjs / parse.js - Parse module
  • timezone.mjs / timezone.js - Timezone module
  • temporal.mjs / temporal.js - Temporal module
  • All corresponding .d.ts files

3. Run Tests

npm test

This will run the comprehensive test suite covering:

  • ✅ Core factory functions
  • ✅ Formatting engine
  • ✅ ISO 8601 parser
  • ✅ Date arithmetic
  • ✅ Comparison operations

Expected: All tests should pass with 95%+ coverage.

For watch mode during development:

npm run test:watch

For coverage report:

npm run test:coverage

4. Type Check

npm run type-check

This verifies TypeScript compilation without emitting files. Expected: No errors (all files use strict TypeScript).

5. Check Bundle Size

npm run size

This validates that bundle sizes are within limits:

  • Core: < 5 KB
  • Format: < 2 KB
  • Parse: < 1.5 KB
  • Timezone: < 3 KB
  • Temporal: < 2 KB

6. Run Benchmarks

npm run benchmark

This compares chroncraft performance against native Date operations.

Expected improvements:

  • Format: 2-3x faster
  • Arithmetic: 2x faster
  • Comparison: 2x faster

7. Try the Examples

# Build first
npm run build

# Then run examples (after adding a script to package.json)
node examples/basic-usage.ts

Or test interactively in Node:

import { createDate, format, addDays } from './dist/index.mjs';

const date = createDate('2025-01-15');
console.log(format(date, 'MMMM D, YYYY')); // January 15, 2025

const future = addDays(date, 7);
console.log(format(future, 'YYYY-MM-DD')); // 2025-01-22

8. Lint the Code (Optional)

npm run lint

This runs ESLint with TypeScript rules to ensure code quality.

9. Development Workflow

For active development:

# Terminal 1: Watch mode build
npm run dev

# Terminal 2: Watch mode tests
npm run test:watch

This gives you instant feedback as you code.

10. Prepare for Publishing (When Ready)

Before publishing to npm:

# Run all pre-publish checks
npm run prepublishOnly

This will:

  1. Build the project
  2. Run all tests
  3. Verify bundle sizes

If everything passes, you can publish to npm:

# Ensure you are logged in to npm
npm login

# Publish the scoped package to https://www.npmjs.com/package/@ian-p1nt0/chroncraft
npm publish

Troubleshooting

If npm install fails:

  1. Ensure Node.js 18+ is installed: node --version
  2. Clear npm cache: npm cache clean --force
  3. Delete package-lock.json and try again

If build fails:

  1. Clean dist folder: rm -rf dist
  2. Clean TypeScript cache: rm -rf .tsbuildinfo
  3. Reinstall dependencies: rm -rf node_modules && npm install

If tests fail:

  1. Make sure you built first: npm run build
  2. Check for TypeScript errors: npm run type-check
  3. Review test output for specific failures
