Tik Tok

Tik Tok is a Javascript tool to easily create beautiful, simple, mobile-friendly, vertical timelines.

Build Status Sauce Browser Test Status

Install

There are many ways to get the code.

  • Use Bower: bower install tik-tok
  • Use npm: npm install tik-tok
  • If you aren't familiar with those technologies, just download the code directly from Github and separately download the dependencies, Underscore and Moment.js.
  • Or just use a public CDN, i.e. hosting from somewhere else. Note that you don't have control over a CDN so if it breaks, which may be unlikely, you're out of luck.

Include

Tik Tok is a Javascript file and a CSS file. You can use RequireJS, AMD, Browserify, or you can manually include the files below like the following:

<!-- Optionally include the Lato font for headings. -->
<link href="http://fonts.googleapis.com/css?family=Lato&subset=latin,latin-ext" rel="stylesheet" type="text/css">

<!-- Dependencies -->
<script src="moment.js"></script>
<script src="underscore.js"></script>

<!-- Tik Tok -->
<link href="dist/tik-tok.css" rel="stylesheet" type="text/css">
<script src="dist/tik-tok.js"></script>

Or, the full CDN version:

<link href="http://fonts.googleapis.com/css?family=Lato&subset=latin,latin-ext" rel="stylesheet" type="text/css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.10.6/moment.min.js"></script>
<link href="https://cdn.rawgit.com/datanews/tik-tok/0.1.1/dist/tik-tok.min.css" rel="stylesheet" type="text/css">
<script src="https://cdn.rawgit.com/datanews/tik-tok/0.1.1/dist/tik-tok.min.js"></script>

Use

Tik Tok is simply a object your create and give it configuration:

var t = new TikTok({
  el: 'example-tik-tok-container',
  entries: [ ... entries data here (see below) ... ]
});

Entries

Entry data should be either an array of objects or a CSV string with the following keys or column headings respectively. The date field is the only absolutely necessary field, though, you probably want at least a title.

JSON example:

{
  // String date, see format option below for what is supported.
  date: '2014-04-01',
  title: 'This is an awesome title',
  body: 'This is the optional main text',
  // Media should be a URL to an image or the embed URL.  This will automatically look
  // for the following types: Youtube, SoundCloud, general iframe/embed, or image
  media: 'http://url.com/to/image.png',
  source: 'This is a source line for your media',
  // Override the media type with this field (this is not usually needed).  Possible values:
  // youtube, soundcloud, soundcloud_large, embed, image
  type: embed,
  // Custom display format for the date of this entry, overrides the global
  // dateDisplay option
  dateDisplay: 'MMM DD, YYYY'
}

CSV example:

date,title,body,media,source
2013-01-01,Great event,"Why not some <em>HTML</em>",,
2013-01-01,Awesome event,"This has a comma, in it.",http://url.com/to/image.png,Cool image

The term "entry" is used instead of "event" as JS uses the term "event" for many things internally.

Options

You can use the following options when defining a Tik Tok timeline:

  • el: The ID string of the DOM element to put your Tik Tok container in. This is required. You can also use CSS selectors if you want.
  • dateFormat: A string or array of strings that will be used to parse dates. If an array is given it will try each format in order. The default is a slightly modified Moment.js default: ['MMM DD, YYYY', 'MM/DD/YYYY', 'M/D/YYYY', 'DD MMM YYYY', 'YYYY-MM-DD', 'YYYY-MM-DD HH:mm:ss']. For more details see the Moment.js parsing docs.
  • dateDisplay: A string for how the entry date will be displayed for each entry in the timeline. See the docs Moment.js formating for a complete list of options. The default is MMM DD, YYYY.
  • descending: Boolean that will make the order of entries descending (newest to oldest) by date if set to true. The default is false which is ascending (oldest to newest).
  • csvDelimiter: The delimiting chracter if you are using a CSV string. The default is ,.
  • csvQuote: The quote chracter if you are using a CSV string. The default is ".
  • groupBy: Tik Tok will automatically group your entries depending on what kind of time they all span. This may not be exactly what you want, so you can override it with this option. Use one of the following values: 'hours', 'days', 'months', 'years', or 'decades'. Default is undefined.
  • groupByDisplay: A string that will determine how the date for each group will be displayed. See the docs Moment.js formating for a complete list of options. The default is dependent on how the groups are determined.
  • keyMapping: If you have entry data that is keyed differently, you can provide a basic object to convert when it is processed. For instance:
    {
    'needed-key': 'provided-key',
    'date': 'this is our crazy keyed date field'
    }
    
  • template: If you want to override the HTML output of the timeline, use your own template. See the src/tik-tok.tpl.html for a starting point. You can provide a string that will be processed with Underscore's template function, or provide your own templating function. The function will be passed the groups of entries, _ (Underscore), the timeline title, and the whole tiktok object.

Methods

  • The update method will re-render the timeline. This method takes the same options object as described above and will override any new options defined. For example:
    var t = new TikTok({
    el: 'example-tik-tok-container',
    entries: [ ... entries data here ... ]
    });
    
    // Change grouping type
    t.update({
    groupBy: 'months'
    });
    
  • The add method will add an entry to the timeline and re-render. This can take in an array of entries, a single object, or a CSV. The second argument can be used to update any options (like the update method). For example:
    var t = new TikTok({
    el: 'example-tik-tok-container',
    entries: []
    });
    
    // Add entries
    t.add([
    { date: '1984-01-01', title: 'Dystopian future starts' },
    { date: '1984-01-02', title: 'Dystopian future a lot like last week' },
    ]);
    

Development and contributing

Instructions on how to do development and make contributions to the project.

Install and environment

Install dependencies. All commands are assumed to be from the Command Line and from the root directory of the project (except for the initial getting of the code).

  1. Install Git.
    • On a Mac, install Homebrew and run: brew install git
    • On common Linux systems: apt-get install git-core
  2. Install NodeJS (io.js should work as well).
    • On a Mac: brew install node
    • On common Linux systems: apt-get install nodejs
  3. Install Gulp command line tool: npm install gulp -g
  4. Install Bower command line tool: npm install bower -g
  5. Get the code (replace with your fork's repository URL) and enter into the code directory: git clone https://github.com/datanews/tik-tok.git && cd tik-tok
  6. Install Node dependencies: npm install
  7. Install Bower dependencies: bower install

Development

Edit files in the src directory; these need to get built into the dist directory. Use these handy Gulp tasks to ease in development:

  • gulp server
    • Runs (and opens) a basic, local web server at port 8089.
    • Automatically builds the source files when they are changes.
    • Runs Livereload and will update the browser when changes are made. Requires installation of the Livereload application or the browser extensions.
  • gulp watch
    • Running tasks that automatically builds the source files when they are changes. The server command does this as well.

Build

After edits are made, run checks and tests and create build version with the following command. Note that building will happen automatically with the above Development tasks.

gulp

Testing

Note that tests are run against the build (dist), not the source, and get run during the main build step, gulp.

  • gulp test: Will run the tests through Node environment and will miss some browser based tests. This will get run automatically when running gulp server.
  • gulp browser-test: Will run tests in given browsers. By default, this will just run the tests in a PhantomJS and Chrome browser through Karma.
    • Multiple cross-browser testing is done with the Sauce Labs service. To run this locally, you will need a Sauce Labs account, and you will need to set the SAUCE_USERNAME and SAUCE_ACCESS_KEY environment variables. There's a handy copy and paste tool at this page if you already have an account.

Continuous integration

Test are run automatically on each push with Travis CI. This will not run the cross-browser tests in Sauce Labs as these seem to timeout or otherwise fail in ways that we have no control over.

Release

The following are the necessary steps for creating a new version of Tik Tok.

  1. Determine the next version according the semantic versioning. This should be in the form of X.X.X.
  2. Update bower.json
  3. Update package.json
  4. Update the download Github URL in the Install section of this file.
  5. Update the URLs used in the CDN example in the Include section of this file.
  6. Run gulp to ensure the build is up to date and all tests pass and the new version is marked in the build.
  7. Make commit: git commit -m "Updating version."
  8. Make tag: git tag X.X.X
  9. Push. Don't forget to add --tags to your push command.
  10. Update NPM: npm publish

Code style and quality

Having consistent code style leads to smoother contributions, easier reviewing, and better and more stable code. Code style is enforced using automatic technologies. Use the following to get your development environment setup.

  1. Install an Editorconfig plugin for your favorite code editor.
    • Editorconfig helps to standardize editor settings like indent spacing.
  2. (optinal) Install a JSCS plugin for your favorite code editor.
    • JSCS is a JS code style enforcer.
    • This is optional since the main build task will run this.
  3. (optional) Install a JSHint plugin for your favorite code editor
    • JSHint is a JS error detection tool.
    • This is optional since the main build task will run this.

Project page

The main project page is hosted on Github Pages through this repository.

We want to include the Bower dependencies in this branch, so this is a helpful command to make that all happen at once (assuming master is up to date).

  • git checkout gh-pages && git merge master && bower install && git add bower_components -f && git commit -m "Adding bower dependencies for project page" && git push origin gh-pages && git checkout master && bower install
  • If you are not updating the Bower dependencies: git checkout gh-pages && git merge master && git push origin gh-pages && git checkout master && bower install
You can’t perform that action at this time.
