gobble-grapher

Displays an interactive graph of your GobbleJS workflow

What

Gobble-grapher is a small tool to help developers understand what is going on in GobbleJS workflows, specially in complex ones.

Gobble-grapher starts a trivial node.js webserver, which will serve a D3-powered interactive directed graph, much like the following image:

Install

As usual, run npm install --save gobble-grapher or npm install --save-dev gobble-grapher before trying to use it.

Note that gobble-grapher is not a gobble plugin, and you won't be interactively prompted about installing it.

How to use

If the end of your gobblefile looks like this:

module.exports = gobble([js, css, whatever]);

Just wrap the last gobble node into a gobble-graph call, like this:

var gobbleGrapher = require('gobble-graph');
module.exports = gobbleGrapher( gobble([js, css, whatever]) );

Then run gobble as usual, or js gobblefile.js if you don't need the build and just want to see the graph. After that, point your favourite web browser to http://localhost:4568.

The graph is interactive: drag the nodes to move them around.

The ideal way to use gobble-grapher is to graph the last node in the workflow. Wrapping other nodes may lead to unexpected results.

Caveats

Gobble-grapher is very young and does the bare minimum. Right now it does not:

• Work well when the gobblefile changes
• Display info about the transformer/merger nodes (options, etc)
• Display the files in a given node
• Reload the files in nodes whenever they change

It also requires an active connection to the internet to pull the D3 library from a CDN.
