broccoli-merge-trees

Copy multiple trees on top of each other, resulting in a single merged tree.

Installation

npm install --save-dev broccoli-merge-trees

Usage

var mergeTrees = require('broccoli-merge-trees');

var outputTree = mergeTrees(inputTrees, options);

inputTrees: An array of trees
options: A hash of options

Options

overwrite: By default, broccoli-merge-trees throws an error when a file exists in multiple trees. If you pass { overwrite: true }, the resulting tree will contain the version of the file as it exists in the last input tree that contains it.

Example

If this is your Brocfile.js:

var mergeTrees = require('broccoli-merge-trees');

module.exports = mergeTrees(['public', 'scripts']);

And your project contains these files:

.
├─ public
│  ├─ index.html
│  └─ images
│     └─ logo.png
├─ scripts
│  └─ app.js
├─ Brocfile.js
…

Then running broccoli build the-output will generate this folder:

the-output
├─ app.js
├─ index.html
└─ images
   └─ logo.png

The parent folders, public and scripts in this case, are not included in the output. The output tree contains only the files within each folder, all mixed together.
