This uses serve.json from the client-config repo, since we currently use
that in production

* fix: create public dir before moving serve.json

* fix: add missing script

* refactor: collect redirect tests

* test: convert to cy.location for stricter tests

* rename certificate folder to 00-certificates

* change crowdin config to recognise new certificates location

* allow translations to be used

* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

--description--

到目前为止,你已经学会了如何将 action dispatch 给 Redux store但到目前为止这些 action 并未包含除 type之外的任何信息。 还可以和 action 一起发送特定数据。 事实上,这是非常常见的,因为 action 通常源于一些用户交互,并且往往会携带一些数据, Redux store 经常需要知道这些数据。

--instructions--

在代码编辑器中定义了一个基础的 notesReducer()addNoteText() action creator。 完成 addNoteText() 函数的主体,这样它就会返回一个 action 对象。 该对象应该包含一个 type 属性,其值为 ADD_NOTE,还有一个传入 action creator 的属性为 textnote 数据。 当调用 action creator 时,需要传入可以访问该对象的特定笔记信息。

接下来,完成在 notesReducer() 中编写的 switch 语句。 需要添加一个处理 addNoteText() 操作的选项。 如果 action 的类型为 ADD_NOTE,就应该触发这个 case并且它应该在传入的 action 上返回 text 属性作为新的 state

这个 action 将在代码底部发送。 一旦完成后,运行代码并观察控制台。 这就是将特定于 action 的数据发送到 store 并在更新 store state时使用它所需的全部内容。

--hints--

action creator addNoteText 应该返回一个包含 typetext 的对象。

assert(
  (function () {
    const addNoteFn = addNoteText('__TEST__NOTE');
    return addNoteFn.type === ADD_NOTE && addNoteFn.text === '__TEST__NOTE';
  })()
);

dispatch 一个 action creator 是 addNoteText 的action ADD_NOTE,应将 state 更新为 action creator 传递的字符串。

assert(
  (function () {
    const initialState = store.getState();
    store.dispatch(addNoteText('__TEST__NOTE'));
    const newState = store.getState();
    return initialState !== newState && newState === '__TEST__NOTE';
  })()
);

--seed--

--seed-contents--

const ADD_NOTE = 'ADD_NOTE';

const notesReducer = (state = 'Initial State', action) => {
  switch(action.type) {
    // Change code below this line

    // Change code above this line
    default:
      return state;
  }
};

const addNoteText = (note) => {
  // Change code below this line

  // Change code above this line
};

const store = Redux.createStore(notesReducer);

console.log(store.getState());
store.dispatch(addNoteText('Hello!'));
console.log(store.getState());

--solutions--

const ADD_NOTE = 'ADD_NOTE';

const notesReducer = (state = 'Initial State', action) => {
  switch(action.type) {
    // Change code below this line
    case ADD_NOTE:
      return action.text;
    // Change code above this line
    default:
      return state;
  }
};

const addNoteText = (note) => {
  // Change code below this line
  return {
    type: ADD_NOTE,
    text: note
  }
  // Change code above this line
};

const store = Redux.createStore(notesReducer);

console.log(store.getState());
store.dispatch(addNoteText('Hello Redux!'));
console.log(store.getState());
