subdeps

subdeps

Trace the dependency graph of a javascript file using detective and resolve.

examples

tree.js

var subdeps = require('../');
var deps = subdeps.sync(__dirname + '/tree/start.js');
console.dir(deps);

output:

substack : node-subdeps $ node example/tree.js 
[ '/home/substack/projects/node-subdeps/example/tree/start.js',
  '/home/substack/projects/node-subdeps/node_modules/detective/index.js',
  '/home/substack/projects/node-subdeps/node_modules/detective/node_modules/burrito/index.js',
  '/home/substack/projects/node-subdeps/node_modules/detective/node_modules/burrito/node_modules/uglify-js/uglify-js.js',
  '/home/substack/projects/node-subdeps/node_modules/detective/node_modules/burrito/node_modules/uglify-js/lib/parse-js.js',

  '/home/substack/projects/node-subdeps/example/tree/lib/util.js',
  '/home/substack/projects/node-subdeps/example/tree/x.js' ]
substack : node-subdeps $ 

memory.js

var subdeps = require('../');
var deps = subdeps.sync('/a.js', { sources : {
    '/a.js' : "var b = require('./b');",
    '/b.js' : "var c = require('f')",
    '/c.js' : "var d = require('./lib/d.js')",
    '/lib/d.js' : "var e = require('e');",
    '/node_modules/e/index.js' : '55',
    '/node_modules/f/beep.js' : '"boop"',
    '/node_modules/f/package.json' : JSON.stringify({ main : "beep.js" })
} });
console.dir(deps);

output:

[ '/a.js', '/b.js', '/node_modules/f/beep.js' ]

methods

var subdeps = require('subdeps');

subdeps.sync(filename, opts)

Return an array of dependencies starting from the file filename and expanding out recursively and synchronously.

Overload resolve's normal behavior with:

• opts.isFile
• opts.readFileSync

If you have an object mapping filenames to string contents, pass it in as opts.sources and the file will be used for dependency analysis entirely in-memory.

install

With npm do:

npm install subdeps

and for the CLI tool do:

npm install -g subdeps
