Adding new pages

So far, we are able to change and remove pages from our content management system. We ended the last chapter by seeding our local storage with a serialized array, so we could see it in action. Let's take a step back and make a way to create new pages through the interface.

First, we'll add an insert method and update the constructor method of Backend:

constructor() {
    super();

    var pages = LocalStore.get("pages", []);

    this.id = 1;

    this.pages = pages.map((page) => {
        page.id = this.id++;
        return page;
    });
}

insert() {
    this.pages.push({
        "id": this.id,
        "title": "New page " + this.id,
        "body": ""
    });

    this.id++;

    LocalStore.set("pages", this.pages);

    this.emit("update", this.pages);
}

The page id values aren't really important to us outside the context of our React components. So, it's fine to regenerate...
