Get the dependency tree of a module
npm install dependency-tree
var dependencyTree = require('dependency-tree');
// Returns a dependency tree for the given file
var tree = dependencyTree('path/to/a/file', 'path/to/all/js/files');
// Returns a pre-order traversal of the tree with duplicate sub-trees pruned.
var preOrderList = dependencyTree.traversePreOrder(tree);
// Returns a post-order traversal of the tree with duplicate sub-trees pruned.
// This is useful for bundling source files, because the list gives the
// concatenation order.
var postOrderList = dependencyTree.traversePostOrder(tree);Returns the entire dependency tree as an object containing the absolute path of the entry file (tree.root) and a mapping from each processed file to its direct dependencies (tree.nodes). For example, the following yields the direct dependencies (child, but not grand-child dependencies) of the root file:
var dependencyTree = require('dependency-tree');
var tree = dependencyTree('path/to/a/file', 'path/to/all/js/files');
var rootDependencies = tree.nodes[tree.root];- All core Node modules (assert, path, fs, etc) are removed from the dependency list by default
- Works for AMD, CommonJS, ES6 modules and SASS files.
Optional
cache: 3rd argument that's an empty object (or shared across multiple runs of this module) used for avoiding redundant subtree generations.
Shell version (assuming npm install -g dependency-tree):
tree filename root
Prints the pre-order and post-order traversals of the dependency tree
Pre-Order:
/a.js
/b.js
/c.js
Post-Order:
/b.js
/c.js
/a.js
