Cloud Grapher

~ ~

Cloud Grapher is a simple one page visualization tool for CloudFormation scripts.

Writing CloudFormation scripts can be a painstaking job and understanding somebody else's script burns brain cells. Cloud grapher should reduce some of the pain. Visualizing scripts is better for presentations as well.

Current features:

• basic editing using CodeMirror
• opening a script by dropping it on the editor or using the menu
• saving a script
• showing a graph generated with cytoscape.js
• saving the graph
• loading a template from a remote URL through jsonp.afeld.me

Development

The default action is to do clean build. This re-generates all html, javascript, images and styles. It is mandatory to use the build command before most tasks because without it some resources might not exist as expected.

Running tests

After build you can run test to verify the code. Use test-watch to verify code on each save.

Note: a build failure will crash the watching of files and you'll need to restart the test-watch command.

Hacking with livereload

Application code can be served locally with a watch by running gulp serve. Any changes will be picked up and any browser will live reload, unless a build failure occurs.

Releasing a new version

There are two steps to releasing a new version:

1. run a clean build to assure all generate resources are in the correct place
2. run a patch|feature|`release``

Without a clean build the release will be botched, not all files might be present.

There are three gulp commands available to bump the version number and tag the repository with it:

gulp patch     # makes v0.1.0 → v0.1.1
gulp feature   # makes v0.1.1 → v0.2.0
gulp release   # makes v0.2.1 → v1.0.0

Patches fix bugs, features introduce one or more new features, a release are usually backwards-incompatible changes affecting either front or back-end.

Please read http://semver.org/ for extra guidelines when to use which option.

Deploying a new version

The currently generated files in the distfolder are deployed to GitHub pages with the gulp deploy command.

Note: Running a deploy without a full build will result in a broken deployment
