Quick Start

Initialize Templates

import { createApp } from 'rnode-server';

const app = createApp();

// Initialize Tera templates
app.initTemplates('./templates/**/*.html', { autoescape: true });

Render Template

app.get('/welcome', (req, res) => {
  const result = app.renderTemplate('welcome.html', {
    title: 'Welcome',
    user: { name: 'John', email: 'john@example.com' },
    items: ['Item 1', 'Item 2', 'Item 3']
  });
  
  const parsed = JSON.parse(result);
  if (parsed.success) {
    res.html(parsed.content);
  } else {
    res.status(500).json({ error: parsed.error });
  }
});

Template Features

• Variables -

• Loops - {% for item in items %}...{% endfor %}
• Filters - 0

Template Options

app.initTemplates('./templates/**/*.html', {
  autoescape: true,        // Auto-escape HTML
  // Add other Tera options as needed
});
