usm.io

What is this?

usm.io can render a User Story Map described in XML into a SVG graphic.

How do I use it?

You need to have Node.js and npm installed globally.

Build it

To build the library, run

$ npm run build

from the root of this repository.

This will create a bundled version of the library in dist/.

This will also copy the bundle to the folder web/3rdparty/usm.io of the example app. So you can re-build the library while running the example app in the browser as explained in the next section. Just re-load the page after the build has finished.

Run the example app

This library comes with an example app. To start it, run

$ npm start

from the root of this repository.

The app will be available at localhost:8080 via your webbrowser. Open the page and you will see a rendered User Story Map.

The example app is served by a webserver that also serves the example data located at data/. You can edit the User Story Map by editing the file data/usm.xml in your favorite text editor while the app is running. Just re-load the web page after saving the changes to usm.xml.

Use the library in your own app

After building you can copy the bundled version from dist/ to your own app.

You have to include it in your browser via a script tag. Then you can create the User Story Map as shown in index.html of the example app.

If you don't want to build the library yourself, you can use the pre-built library instead. Just link to https://apis.frederikheld.de/usmio/usmio.min.js in the script tag.

Beware: This is the latest build, so it might behave unexpected!

But why?

I was looking for a way to maintain an User Story Map directly in my repository. To achieve this I needed a easy way to create a map that is diffable and does not focus on the graphical representation but on the inforation in the map. There was no such tool so I wrote this one.

What is an User Story Map?

User Story Mapping is a method to represent your Agile Product Backlog in multiple dimensions. It's a very visual approach to maintaining a Backlog because it gives you a better overview of your product and your roadmap. Thanks to these qualities it is an excellent base for discussions with your stakeholders.

For more information on User Story Mapping see Jeff Pattons website or read his book about User Story Mapping.

How does it work?

The implementation is in JavaScript using the D3 library to create the SVG.

To display the user interface it runs a little webserver written in Node.js using the express library.

Right now the code is still a bit messed up, so it might be a bit difficult for you to catch on. I'm trying to fix this as fast as I'm learning JS and D3.

Basically I tried to represent each element of the USM as an object. The objects are nested as the elements in the USM are. Each object renders it's graphical representation as a SVG group which is transformed to it's position in relation to the parent group.

How can I contribute?

So if you would like to take the challenge, feel free to send me pull requests with your contribution! I'm especially happy about hints how to apply common design patterns in JS.

What's next?

Next steps are:

To Do

  • Add display of card details when clicking on a card
  • Make Activities optional
  • Implement tagging to visually emphasize groups of cards
  • Get rid of bodies do make xml and implementation less complicated?
  • Implement a way to store the SVG as PNG or JPG
  • Implement interactive editing

Done

  • Bundle library for use in browsers
  • Add a command line interface so that usm.io can be used in a build pipeline
  • Implement word wrap for card titles
  • Implement activities above steps
  • Modularized JS
  • Fix scaling of SVG

The overall challenge is to structure the code in a more readable and maintainable way by applying common design patterns.
