An example of a dynamic oracle

[glitch003]

Let the user pass in a URL, attach it to the signed data. Anyone can use this as a generic oracle.

If we have to define .properties.periods[0].temperature then it's not truly dynamic is it?

Maybe we want to include this helper function in the Lit Action:

/**
 * Extracts a nested value from an object using a dot-notation path string that can include array indices.
 * 
 * @param {string} responseValue - The path string using dot notation (e.g. 'users[0].name' or 'meta.totalUsers')
 * @param {any} data - The object to extract the value from
 * @returns {any} The value at the specified path
 * 
 * @example
 * const data = {
 *   users: [
 *     { id: 1, name: 'Alice' },
 *     { id: 2, name: 'Bob' }
 *   ],
 *   meta: { totalUsers: 2 }
 * };
 * 
 * getValueFromResponse('users[0].name', data); // Returns 'Alice'
 * getValueFromResponse('users[1].id', data);   // Returns 2
 * getValueFromResponse('meta.totalUsers', data); // Returns 2
 */
export function getValueFromResponse(responseValue: string, data: any): any {
  return responseValue.split('.').reduce((acc: any, key: string) => {
    const arrayMatch = key.match(/(\w+)\[(\d+)\]/);

    if (arrayMatch) {
      const [, arrayKey, index] = arrayMatch;
      return acc?.[arrayKey]?.[parseInt(index)];
    } else {
      return acc?.[key];
    }
  }, data);
}

Then in jsParam define the path you want to access

jsParams:{
  responsePath: 'properties.periods[0].temperature'
}
