JSON Resume Reference Theme

Reference implementation demonstrating @resume/core best practices

This theme serves as a complete example of how to build ATS-friendly, framework-agnostic resume themes using the @resume/core component library. It's designed to be a template for AI agents and developers to rapidly create new themes.

Features

• Framework-Agnostic: Pure functions, no React/Vue/framework lock-in
• ATS-Friendly: Single-column layout, standard fonts, semantic HTML
• Fully Tested: 17 comprehensive tests covering all sections
• Print-Optimized: Ready for PDF generation and printing
• Composable: Uses all @resume/core primitives (Section, SectionTitle, ListItem, DateRange, Badge)
• Themeable: CSS variables for easy customization
• Complete: Supports all JSON Resume schema sections

Installation

npm install jsonresume-theme-reference @resume/core

Usage

Basic Example

import { render } from 'jsonresume-theme-reference';

const resume = {
  basics: {
    name: 'Jane Doe',
    label: 'Software Engineer',
    email: '[email protected]',
    // ... rest of JSON Resume data
  },
  work: [/* ... */],
  education: [/* ... */],
  // ...
};

const html = render(resume);

Complete Example (All Features)

import { render } from 'jsonresume-theme-reference';
import { validateATS } from '@resume/ats-validator';
import fs from 'fs';

// Complete JSON Resume with all 11 sections
const resume = {
  basics: {
    name: 'Jane Doe',
    label: 'Senior Software Engineer',
    image: '',  // Leave empty for ATS compatibility

What This Theme Demonstrates

1. Using @resume/core Primitives

import { Section, SectionTitle, ListItem, DateRange, Badge, BadgeList } from '@resume/core';

// Create structured sections
const workSection = Section({
  id: 'work',
  content: `
    ${SectionTitle({ title: 'Work Experience' })}
    ${ListItem({
      title: 'Senior Engineer',
      subtitle: 'TechCorp',
      dateRange: DateRange({ startDate: '2020-01', endDate: null }),
      highlights: ['Led team of 5', 'Reduced costs by 30%'],
    })}
  `,
});

2. ATS-Friendly Structure

• Single-column layout (no sidebars)
• Semantic HTML (<header>, <section>, <h1>-<h6>)
• Standard fonts (Helvetica, Arial)
• No tables or complex layouts
• Proper heading hierarchy

3. Comprehensive Section Coverage

Supports all JSON Resume sections:

• ✅ Basics (name, contact, summary)
• ✅ Work Experience
• ✅ Education
• ✅ Skills (with badge lists)
• ✅ Projects
• ✅ Volunteer
• ✅ Awards
• ✅ Publications
• ✅ Languages
• ✅ Interests
• ✅ References

4. Graceful Handling of Missing Data

// Works with minimal data
const minimalResume = {
  basics: { name: 'John Doe' }
};
const html = render(minimalResume); // No errors, renders what's available

5. Print Optimization

• Uses CSS variables for consistent spacing
• Respects @media print rules from @resume/core
• Single-page optimized (660px max width)

ATS Validation Integration

This theme is built following ATS-friendly guidelines. You can validate any theme output using @resume/ats-validator:

import { render } from 'jsonresume-theme-reference';
import { validateATS } from '@resume/ats-validator';

const resume = { /* your resume data */ };
const html = render(resume);

// Validate ATS compatibility
const validation = validateATS(html);

console.log(`ATS Score: ${validation.score}/100`);
console.log(`Passes: ${validation.passes ? 'Yes' : 'No'}`);

if (!validation.passes) {
  console.log('Issues found:');
  validation.issues.forEach(issue => {
    console.log(`- ${issue.message}`);
  });
}

Reference Theme ATS Compliance:

• ✅ Single-column layout
• ✅ Semantic HTML structure
• ✅ Standard fonts (Helvetica, Arial)
• ✅ No tables for layout
• ✅ No images or charts
• ✅ Proper heading hierarchy (h1 → h2 → h3)
• ✅ Print-optimized (660px max width)

Typical ATS Score: 95+/100

For AI Agents: How to Build New Themes

This theme is your blueprint. Follow these steps:

Step 1: Copy the Structure

cp -r packages/jsonresume-theme-reference packages/jsonresume-theme-yourtheme

Step 2: Customize Design Tokens

/* Override CSS variables */
:root {
  --resume-color-accent: #8b5cf6; /* Your brand color */
  --resume-font-sans: 'Inter', sans-serif; /* Your font */
}

Step 3: Modify Section Layouts

// Example: Two-column skills layout
function renderSkills(skills) {
  return Section({
    id: 'skills',
    className: 'two-column-grid', // Add custom class
    content: /* ... */
  });
}

Step 4: Add Custom Styles

Keep inline styles in the <style> tag or extract to separate CSS file.

Step 5: Test Everything

pnpm --filter jsonresume-theme-yourtheme test

Architecture Patterns

Pure Functions

All render functions are pure - same input always produces same output:

function renderWork(work) {
  // No side effects, no external dependencies
  return work.map(job => ListItem({ /* ... */ })).join('\n');
}

Composition Over Configuration

Build complex layouts by composing primitives:

Section({
  content: `
    ${SectionTitle({ title: 'Skills' })}
    ${skills.map(group => `
      <div>
        ${group.name}
        ${BadgeList({ items: group.keywords })}
      </div>
    `).join('')}
  `
})

Single Responsibility

Each function does one thing:

• renderHero() - Hero section only
• renderWork() - Work section only
• renderSkills() - Skills section only

Testing Strategy

See tests/theme.test.js for comprehensive examples:

it('renders work experience section', () => {
  const html = render(completeResume);
  expect(html).toContain('Work Experience');
  expect(html).toContain('TechCorp Inc');
  expect(html).toContain('Present'); // DateRange component
});

it('uses all @resume/core primitives', () => {
  const html = render(completeResume);
  expect(html).toContain('resume-section'); // Section
  expect(html).toContain('resume-badge'); // Badge
  expect(html).toContain('resume-item'); // ListItem
});

Performance

• Bundle Size: ~8KB minified (no dependencies except @resume/core)
• Render Time: <10ms for typical resume
• Framework: None (pure functions)

Browser Support

Works in all modern browsers and generates static HTML for:

• Web viewing
• PDF generation
• Email clients
• Static site generation
