node-resolve-dependency-graph

Simple dependecy resolving algorithm. Expects an id map of dependencies.

Setup

npm install node-resolve-dependency-graph

Quick Start

import {resolve,resolveMap, flat as flatten, map, tree as buildTree} from 'node-resolve-dependency-graph';

let dependencyMap = {
    a: ['b', 'c'], 
    b: [], 
    c: ['b'], 
    d: ['b','e'], 
    e: ['f'], 
    f: []
}

let resolved = resolve (dependencyMap); 

[ [ 'b', 'c', 'a' ],        
  [ 'b' ],
  [ 'b', 'c' ],
  [ 'b', 'f', 'e', 'd' ],
  [ 'f', 'e' ],
  [ 'f' ] ]

ES5

const depResolve = require ("node-resolve-dependency-graph/lib");

Views

You can transform the output using the helpers.

flat returns a flat list, with duplicate nodes filtered out.

let flat = flatten(resolved);
[ 'b', 'c', 'a', 'f', 'e', 'd' ]

map returns a map with flat arrays for each dependency group. Intermediate groups are included.

let mapped = map (resolved);
let mapped = resolveMap (dependencyMap);

{ f: [ 'f' ],
  e: [ 'f', 'e' ],
  d: [ 'b', 'f', 'e', 'd' ],
  c: [ 'b', 'c' ],
  b: [ 'b' ],
  a: [ 'b', 'c', 'a' ] }

tree returns a tree

let tree = buildTree (resolved)
{ f: null,
  e: { f: null },
  d: { b: { f: [Object] } },
  c: { b: null },
  b: null,
  a: { b: { c: null } } }
