Migration from 5.X

New TVML renderer with unified way to create documents

Now every document must be React.js component. And here is how you can migrate your old components

Static documents translates to:

TVDML
  .handleRoute('start')
  .pipe(TVDML.render(() => (
    <document>
      <alertTemplate>
        <title>Hello world</title>
        <button>
          <text>Ok</text>
        </button>
      </alertTemplate>
    </document>
  )));

Rendering document with render factory stays exactly the same.

To migrate your interactive components use create-react-class module to transform old code to React.js components. Or update your old components to React.js ES6 syntax with this guide.

Updated example from "Load more" implementation

import createReactClass from 'create-react-class';

const TVShows = createReactClass({
  getInitialState() {
    return {
      page: 1,
      tvshows: [],
      loading: true,
    };
  },

  componentDidMount() {
    // Loading initial tv shows list when component is mounted
    downloadTVShows(this.state.page).then(tvshows => {
      this.setState({
        tvshows,
        loading: false,
      });
    });
  },

  render() {
    // Showing spinner while initial data is loading
    if (this.state.loading) {
      return (
        <document>
          <loadingTemplate>
            <activityIndicator />
          </loadingTemplate>
        </document>
      );
    }

    return (
      <document>
        <stackTemplate>
          <banner>
            <title>TV Shows</title>
          </banner>
          <collectionList>
            <grid>
              {this.state.tvshows.map(tvshow => {
                return (
                  <lockup key={tvshow.id}>
                    <img src={tvshow.cover} width="250" height="250" />
                    <title>{tvshow.title}</title>
                  </lockup>
                );
              })}
            </grid>
            <separator>
              <button onSelect={this.onLoadNextPage}>
                <text>Load page #{this.state.page + 1}</text>
              </button>
            </separator>
          </collectionList>
        </stackTemplate>
      </document>
    );
  },

  onLoadNextPage() {
    const nextPage = this.state.page + 1;

    // Loading next page and merging new data with existing.
    // Document update will be immediately invoked on state change.
    downloadTVShows(nextPage).then(tvshows => {
      this.setState({
        page: nextPage,
        tvshows: this.state.tvshows.concat(tvshows),
      });
    });
  },
});

TVDML
  .handleRoute('start')
  .pipe(TVDML.render(() => (
    <TVShows />
  )));

Updated style syntax

Update is pretty simple.

This example:

<document>
  <head>
    <style content={`
      .controls_container {
        ...
      }
      ...
    `} />
  </head>
  <compilationTemplate>
    ...
  </compilationTemplate>
<document>

Goes to:

<document>
  <head>
    <style>{`
      .controls_container {
        ...
      }
      ...
    `}</style>
  </head>
  <compilationTemplate>
    ...
  </compilationTemplate>
<document>

It's important to note that inline styles are must be defined as object with props named written in camelCase as keys.

This styles:

<title style="tv-text-highlight-style: marquee-on-highlight; color: rgb(84, 82, 80)">
  Hello world
</title>

Transforms to:

<title style={{
  tvTextHighlightStyle: 'marquee-on-highlight',
  color: 'rgb(84, 82, 80)',
}}>
  Hello world
</title>

New TVDML.renderModal() rerendering behavour

Every next invocation of TVDML.renderModal() will rerender active modal without closing it.

Please check TVDML.dismissModal() if you need to keep old behavour.
