Passing data to templates

To send data to your templates, you can utilise the rw.setProps() method. By passing an object to this method, you are able to dynamically inject data into your templates.

Example 1: Simple Property Passing

const transformHook = (rw) => {
  const message = 'Hello, World!';

  rw.setProps({
    greetingMessage: message
  });
};

exports.transformHook = transformHook;

Example 2: Conditional Logic for Display

const transformHook = (rw) => {
  const { isVisible } = rw.props;

  const display = isVisible ? 'visible' : 'hidden';

  rw.setProps({
    display
  });
};

exports.transformHook = transformHook;

Example 3: Basic Computation and Formatting

const transformHook = (rw) => {
  const { quantity } = rw.props;

  const totalPrice = quantity * 15; // Assuming price per item is 15
  const formattedPrice = `$${totalPrice.toFixed(2)}`;

  rw.setProps({
    formattedPrice
  });
};

exports.transformHook = transformHook;

Example 4: String Manipulation

const transformHook = (rw) => {
  const { username } = rw.props;

  const welcomeMessage = `Welcome, ${username.charAt(0).toUpperCase() + username.slice(1)}!`;

  rw.setProps({
    welcomeMessage
  });
};

exports.transformHook = transformHook;

Example 5: Complex Calculation using collection data

const transformHook = (rw) => {
  const { items } = rw.collections;

  const totalWeight = items.reduce((accumulator, item) => accumulator + item.weight, 0);

  const shippingCost = totalWeight > 10 ? totalWeight * 1.5 : totalWeight * 1.2;

  const formattedShippingCost = `$${shippingCost.toFixed(2)}`;

  rw.setProps({
    totalWeight,
    formattedShippingCost
  });
};

exports.transformHook = transformHook;.
