Wikipedia Game in React

Manages a single round of the Wikipedia Game (shortest path between two articles) using React JS

Component Documentation

WikiSetup

The initial page loaded for the / route. Should load a random article (or one specified by the user) to start the Wikipedia game. Must include a <Link> tag to start the game, e.g.

render() {
  if (this.state.title) {
    var link = {
      pathname: this.state.title,
      state: { titles: [this.state.title] },
    };
    return (
      <Link to={link}>
        <Button>Start with {this.state.title}</Button>
      </Link>
    );
  } else {
    return <div>Loading</div>;
  }
}

WikiGameApp

The entry point for all of your code.

Should display a list of all visited articles via this.props.titles, the target title via this.props.targetTitle, and the current title via this.props.currentTitle.

Should also handle user events. When a user adds a new link, it should call this.props.addTitle(title). When a user selects a new "current title", e.g. when clicking a previously visited title, it should call this.props.setCurrentTitle(title).

WikiApi

YOU SHOULD NOT EDIT THIS FILE.

Implements all necessary Wikipedia API calls:

• WikiApi.getRandomArticles(count): Returns a Promise to a list of random Wikipedia article titles. The list length is determined by the given count parameter.
• WikiApi.getSummary(title): Returns a Promise to a string of the first 500 words of the Wikipedia article for the given title.
• WikiApi.getLinks(title): Returns a Promise to a list of all titles linked in the Wikipedia article of the given title.

An example call using a Promise object is shown below (notice then(function)):

WikiApi.getRandomArticles(10).then(function(titles) {
  for (var i = 0; i < titles.length; i++) {
    console.log(titles[i]);
  }
});

WikiGameHistory

YOU SHOULD NOT EDIT THIS FILE.

Manages all browser history and implements the following methods to be used in WikiGameApp via this.props:

• this.props.addTitle(title): Called when a user adds a new link to the game.
• this.props.setCurrentTitle(title): Called when a user goes "back" in the list of visited Wikipedia Articles.

Also sends the following properties to WikiGameApp:

• this.props.titles: The list of all visited titles (including the starter title)
• this.props.currentTitle: The current title a user is viewing.
• this.props.targetTitle: The title users should eventually reach.
• this.props.isComplete: Is true if the game is done!
