JarCastingbroccoli-merge-trees
Copy multiple trees of files on top of each other, resulting in a single merged tree.
Installation
npm install --save-dev broccoli-merge-trees
Usage
- As a
function call
const broccoliMergeTrees = require('broccoli-merge-trees');
let mergedNode = broccoliMergeTrees(inputNodes, options);
- With
new
const { MergeTrees } = require('broccoli-merge-trees');
let mergedNode = new MergeTrees(inputNodes, options);
-
inputNodes: An array of nodes, whose contents will be merged -
options: A hash of options
Options
-
overwrite: By default, broccoli-merge-trees throws an error when a file exists in multiple nodes. If you pass{ overwrite: true }, the output will contain the version of the file as it exists in the last input node that contains it. -
annotation: A note to help tell multiple plugin instances apart. -
destDir: A string representing the destination path that merged files will be copied to.
Example
If this is your Brocfile.js:
const mergeTrees = require('broccoli-merge-trees');
module.exports = function() {
return 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.
If this is your Brocfile.js:
var BroccoliMergeTrees = require('broccoli-merge-trees');
module.exports = new BroccoliMergeTrees(['public', 'scripts'], {
destDir: 'assets'
});
Then running broccoli build the-output will generate this folder:
the-output
└─ assets
├─ app.js
├─ index.html
└─ images
└─ logo.png
