JQuery starter project for prismic.io

This is a purely client-side application using JQuery, that will connect to any prismic.io repository, and trivially list its documents. It uses the prismic.io JavaScript development kit, and provides a few helpers to integrate with JQuery, as well as a basic templating engine.

The embedded templating engine is JavaScript Micro-templating (http://ejohn.org/blog/javascript-micro-templating/), but you can easily switch for any other JavaScript templating engine you may want.

This starter project uses the browser sessionStorage to store the access token when you interactively login to preview the future releases of your repository. Therefore, to preview another release than Master, a modern browser supporting HTML5 is required.

Getting started

Launch the starter project

Since it's all client-side, you don't need more than a web browser: simply open the index.html file in your browser.

If you wish to simulate a client-server architecture anyway, you can also launch a local Web server using the server.sh script and open the home page at http://localhost:8000/ (Python is required)

Your JQuery starter project is now working! However, by default, it will list and display documents from our "Les Bonnes Choses" example repository.

Configure the starter project

Edit the js/prismic-configuration.js file to make the application point to the correct repository:

var Configuration = {

  // -- API endpoint
  apiEndpoint: 'https://lesbonneschoses.prismic.io/api',

  // -- Access token if the Master is not open
  // accessToken: 'xxxxxx'
  
}

Publish your project

As this application is just made of static files, you can publish it to any web server. One simple way to do that is to use Github pages. Just push this Git repository on Github and create a gh-pages branch to publish it to your own Github pages:

git checkout --orphan gh-pages
git commit -a -m "Push to Github pages"
git push origin gh-pages

You can then visit your website at:

http://your-github-user.github.io/your-github-repository.

Get started with prismic.io

You can find out how to get started with prismic.io on our prismic.io developer's portal.

Understand the JavaScript development kit

You'll find more information about how to use the development kit included in this starter project, by reading its README file.

Specifics and helpers of the JQuery starter project

There are several places in this project where you'll be able to find helpful helpers of many kinds. You may want to learn about them in order to know your starter project better, or to take those that you think might be useful to you in order to integrate prismic.io in an existing app.

  • in js/prismic-configuration.js:
    • this is where you set you API endpoint and security to access your repository's API;
    • you will also find the linkResolver closure that gets passed around to resolve your links (read more in the last paragraph of our API documentation);
    • you will also find the closure that gets executed when the API returns an error.
  • in js/prismic-helpers.js:
    • a getApiHome function that creates the Api object using the configuration in the prismic-configuration.js file;
    • a buildContext function that creates the ctx object that will be passed around (containing the Api object, the ref, the linkResolver closure, etc.
    • a withPrismic function that we'll start every "controller" with, so that the rest of it (that we'll write in the callback) can directly use ctx, and therefore the properly prepared Api object, and everything that is necessary to get stuff done.
    • also, some URL parsing helpers: queryString and encodedHash.
  • in js/prismic-template.js:
    • a very basic templating system based on John Resig's micro-templating and JQuery, so that you can simply call $(#your-element-id).render(vars, callback)

You can see the typical architecture of an HTML page if you look at the index.html file:

  • Scripts: including them at the top of the page (note that you can also include them at the bottom)
  • Content release selectbox: only appears when the user is logged in, and allows to select a future content release to preview
  • View: with the bits of template to trigger
  • Controller at the bottom: does the queries, and triggers the rendering of templates:
    • start with Helpers.withPrismic to make sure your ctx is properly prepared for you;
    • in the callback of Helpers.withPrismic, perform your API calls, one after the other, each one inside the previous one's callback (if you feel this is not as clean as could be, you can learn about promises and the Q library), and make sure to properly deal with errors;
    • in the last callback, render the page, by calling render on DOM elements that contain your templates.
