Note: query parameter values + * default to a special `"auto"` mode. + * + * For query parameters in `"auto"` mode, if multiple values for a single parameter + * are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values + * are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`). However, if + * only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single + * value (e.g.: `{ foo: '1' }`). + * + * <pre>params: { + * param1: { array: true } + * }</pre> + * + * - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when + * the current parameter value is the same as the default value. If `squash` is not set, it uses the + * configured default squash policy. + * (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`}) + * + * There are three squash settings: + * + * - false: The parameter's default value is not squashed. It is encoded and included in the URL + * - true: The parameter's default value is omitted from the URL. If the parameter is preceeded and followed + * by slashes in the state's `url` declaration, then one of those slashes are omitted. + * This can allow for cleaner looking URLs. + * - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of your choice. + * + * <pre>params: { + * param1: { + * value: "defaultId", + * squash: true + * } } + * // squash "defaultValue" to "~" + * params: { + * param1: { + * value: "defaultValue", + * squash: "~" + * } } + * </pre> + * + * + * @example + * <pre> + * // Some state name examples + * + * // stateName can be a single top-level name (must be unique). + * $stateProvider.state("home", {}); + * + * // Or it can be a nested state name.
