Creating a Graph Instance
var DependencyGraph = require('dependency-foo'); var graph = new DependencyGraph();
Declaring a Dependency between two nodes
// The human has now a dependency to the air. graph.subject('human').dependsOn('air');
Checking Dependencies & Direction
// I need to know if air is a dependency of human. graph.subject('air').isDependencyOf('human'); => true // I need to know if human has a dependency to the air graph.subject('human').hasDependencyTo('air'); => true
// What nodes are referencing 'air' as a dependency? graph.subject('air').references => ['human'] // What nodes are dependencies of 'human'? graph.subject('human').dependencies => ['air']
Removing a Dependency
// The human don't want to depend of the air anymore. graph.subject('human').drop('air'); graph.subject('human').dependencies =>  // The references are automatically removed. graph.subject('air').references =>
