Redux 的 PHP 版本,部分灵感来自 Redux 的端口,以及 RafaelFontesrikbruil 的端口。

背景

这个库是为了在交互式 CLI 应用程序框架中使用而创建的。

示例用法

Reducer

// Create a reducer.
$reducer = function($state, ActionInterface $action) {
    switch ($action->getType()) {
        case 'add':
            $state += $action->getPayload();
            break;
        case 'subtract':
            $state -= $action->getPayload();
            break;
    }
    return $state;
};
$initialState = 0;

// Create the store.
$store = Redux::createStore($reducer, $initialState);

// Dispatch some actions.
$store->dispatch(new Action('add', 5));
$store->dispatch(new Action('subtract', 2));

assert(3 === $store->getState());

中间件

中间件只是可调用的。如果您不想使用闭包,可以扩展 Ctefan\Redux\Middleware\AbstractMiddleware 并实现方法 handleAction(ActionInterface $action, callable $next)

// Create the middleware.
$middleware = function(callable $getState, callable $dispatch): callable {
    return function($next): callable {
        return function(ActionInterface $action) use ($next) {
            // TODO do something like fetching data from a remote server, waiting for a promise etc.
            return $next($action);
        }
    }
};

// Create the store.
$store = Redux::createStore($reducer, $initialState, Redux::applyMiddleware($middleware));
