We turn

Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!

into

You will need Raphaël, underscore.js (or lodash), and optionally jQuery.

Just run bower install bramp/js-sequence-diagrams and include the scripts below:

<script src="{{ bower directory }}/raphael/raphael-min.js"></script>
<script src="{{ bower directory }}/underscore/underscore-min.js"></script>
<script src="{{ bower directory }}/js-sequence-diagrams/build/sequence-diagram-min.js"></script>

You can download the dependencies (see requirements above) and include them on your page like so:

<script src="underscore-min.js"></script>
<script src="raphael-min.js"></script>
<script src="sequence-diagram-min.js"></script>

You can use the Diagram class like:

<div id="diagram">Diagram will be placed here</div>
<script> 
  var diagram = Diagram.parse("A->B: Does something");
  diagram.drawSVG('diagram');
</script>

or use jQuery to do all the work:

<div class="diagram">A->B: Message</div>
<script>
$(".diagram").sequenceDiagram({theme: 'hand'});
</script>

The build is managed by a Makefile, and uses various tools available from npm. Thus both make and npm are required, and can easily be installed on any Linux or Mac machine.

make

The Makefile will use npm to install all the dev dependencies, build, and test.

We use qunit for testing. It can be ran from the command line, or via a browser. The command line actually tests multiple permutations of lodash, Underscore, and with and without minification.

make test
...
Global summary:
┌───────┬───────┬────────────┬────────┬────────┬─────────┐
│ Files │ Tests │ Assertions │ Failed │ Passed │ Runtime │
├───────┼───────┼────────────┼────────┼────────┼─────────┤
│ 1     │ 13    │ 231        │ 0      │ 231    │ 250     │
└───────┴───────┴────────────┴────────┴────────┴─────────┘

or make and then open test/qunit.html in a browser. Finally a simple playground is available at test/test.html.

• Make sure all changes checked in
• Bump version in src/main.js and bower.json
• make clean
• make
• git add -f src/main.js bower.json build/sequence-diagram-min.js build/sequence-diagram-min.js.map
• git commit -m "Released version 1.x.x"
• git push origin master
• git tag -a v1.x.x -m v1.x.x
• git push origin v1.x.x

Raphael requires Cufon style fonts. Find the font you want in ttf or otf format, visit Cufon's site and process it into a javascript file. Then ensure the font is included via the HTML, or recompile after altering main.js. So far only the hand drawn font, Daniel Bold, has been included.

• Other themes
• Rethink the use of Raphael. Due to its support of VML (which I don't care about), it makes many things harder. For example, font support, css styling, etc. Perhaps draw the SVG by hand, or find a small helper library
• Automate the release process
• Dozens of other issues on https://github.com/bramp/js-sequence-diagrams/issues

via GitHub

This project makes use of Jison, Raphaël, underscore.js, and the awersome Daniel font (which is free to use for any purpose).

Many thanks to Web Sequence Diagrams which greatly inspired this project, and forms the basis for the syntax.

• flowchart.js A similar project that draws flow charts in the browser
