JavaScript library for defining types and their properties with support for wrapping/unwrapping and serialization/deserialization.

module.exports = require('./Model').extend({
  typeName: 'boolean',
  wrap: false,
  coerce: function (value, options) {
    if (options.strict) {
      // strict mode
      if (value != null && (value.constructor !== Boolean)) {
        this.coercionError(value, options);
      }
      return value;
    }

    if (value == null) {
      return value;
    } else if (value.constructor === String) {
      return (value === 'true');
    }

    return !!value;
  }
});
