Validation Helpers

Helper methods for dealing with header and query-parameter values.

castHeaderValue(value, header, inArray)

Casts finite numbers and boolean values to a string. If value is an array, and inArray is false, do the same for each array item. Such arrays are not allowed to contain other arrays.

Returns the cast value, or throws a TypeError instance if the value is of an unexpected type.

exports.castHeaderValue = function(value, header, inArray) { if (typeof value === 'string' || typeof value === 'number' && isFinite(value) || typeof value === 'boolean') { return value + ''; } if (!inArray && Array.isArray(value)) { return value.map(function(value) { return exports.castHeaderValue(value, header, true); }); } throw new TypeError('Unexpected value for `' + header + '` header.'); };

castQueryValue(value, param)

Casts finite numbers and boolean values to a string.

Returns the cast value, or throws a TypeError instance if the value is of an unexpected type.

exports.castQueryValue = function(value, param) { if (typeof value === 'string' || typeof value === 'number' && isFinite(value) || typeof value === 'boolean') { return value + ''; } throw new TypeError('Unexpected value for `' + param + '` param.'); };
