What this PR do?

Performs tasks specified for Mini challenge 3

Any background context you want to provide?

Add your google API Key in a file called .env.development under the name of REACT_APP_YOUTUBE_KEY

Notes:

There are uncovered components for testing, sorry... I wanted to make my PR sooner, I'll cover them in a later revision.
I added a prototype for theming, is not finished, do not expect too much.

Where should the reviewer start?

Well... I'm not sure, it was a really big refactor and new features.

How should this be manually tested?

Mini-Challenge 3 Feedback:

Acceptance Criteria

✅ Videos in the Home View are fetched from the YouTube API and displayed correctly.
✅ Users can search for YouTube videos using the search field on the header.
✅ A video can be played from the Video Details View after clicking on it.

Bonus Points

✅ Custom Hooks for API calls are implemented and tested correctly.
✅ Testing coverage is above 60%. (Please include a screenshot of the code coverage report in your PR description).

Improvements

Whenever you have time, it'll be great to apply media queries to have a responsive design

For some reason the video player size is looking weird

Sometimes when I click on a related video the following error appears:

jparciga · 2021-03-17T18:34:16Z

src/components/HomeVideos/HomeVideos.spec.jsx

+  const contextValue = { search: jest.fn(), videos: youtubeMockedData.items };
+  const Wrap = contextWrapper(SearchContext, contextValue, Component);
+  const { container } = renderWithTheme(Wrap, theme);
+  return { container };


That's a nice way to mock the context value 👌🏻

src/components/HomeVideos/VideoCard.test.jsx

+  it('shows content complying with ARIA attributes', () => {
+    const video = youtubeMockedData.items[0];
+    const { container } = build(<VideoCard video={video} />);
+
+    const img = getByRole(container, 'img');
+    const figcaption = container.querySelector('figcaption');
+
+    expect(img).toHaveAttribute('alt', video.snippet.title);
+    expect(img).toHaveAttribute('src', video.snippet.thumbnails.high.url);
+    expect(figcaption).toHaveTextContent(video.snippet.description);
+
+    expect(getByTitle(container, 'video-title')).toHaveTextContent(video.snippet.title);
+    expect(container).toHaveTextContent(video.snippet.description);
+  });


Nice test case!

src/components/Layout/Header.spec.jsx

+  it('fires user search until presses enter', () => {
+    const EXPECTED_TEXT = 'Hello, ';
+    const TRIGGER_TYPING = 'there';
+    const { searchInput, contextValue } = build();
+    fireEvent.change(searchInput(), { target: { value: TRIGGER_TYPING } });
+    fireEvent.change(searchInput(), { target: { value: EXPECTED_TEXT } });
+    expect(searchInput().value).toBe(EXPECTED_TEXT);
+    expect(contextValue.search).not.toHaveBeenCalled();
+    fireEvent.keyPress(searchInput(), { key: 'Enter', code: 13, charCode: 13 });
+    expect(contextValue.search).toHaveBeenCalled();
+  });


Excellent 👏🏻

src/components/Layout/LayoutWrapper.jsx

+const StyledLayoutWrapper = styled.div`
+  background: ${({ theme }) => theme.color.background};
+  width: 100%;
+  height: 100%;

+
+const LayoutWrapper = ({ children }) => {
+  const { theme } = useContext(ThemeContext);
+
+  return (
+    <StyledLayoutWrapper data-testid="layout-wrapper" theme={theme} role="application">


It's not necessary to get the current theme from the context so your styled-components can use it. Since you're wrapping your App using the ThemeProvider all your styled-components will automatically receive the current theme in their props. https://styled-components.com/docs/advanced

Suggested change

const StyledLayoutWrapper = styled.div`

background: ${({ theme }) => theme.color.background};

width: 100%;

height: 100%;

`;

const LayoutWrapper = ({ children }) => {

const { theme } = useContext(ThemeContext);

return (

<StyledLayoutWrapper data-testid="layout-wrapper" theme={theme} role="application">

const StyledLayoutWrapper = styled.div`

background: ${({ theme }) => theme.color.background};

width: 100%;

height: 100%;

src/components/VideoPlayer/VideoPlayerContainer.jsx

+  useEffect(() => {
+    /* global YT */
+    /* eslint no-undef: "error" */
+      window.player = new YT.Player('player', {
+        height: '50%', 
+        width: '60%',
+        videoId,
+      });
+  });


It might be a good idea to add the videoId as a dependency for this useEffect so this code its executed only when the videoId changes.

Suggested change

useEffect(() => {

/* global YT */

/* eslint no-undef: "error" */

window.player = new YT.Player('player', {

height: '50%',

width: '60%',

videoId,

});

});

useEffect(() => {

/* global YT */

/* eslint no-undef: "error" */

window.player = new YT.Player('player', {

height: '50%',

width: '60%',

videoId,

});

}, [videoId]);
