broccoli-duplicate-watched-tree-finder

A utility to list all watched Broccoli trees and find duplicates.

Duplicate watched trees might consume extra resources on your machine. So why not avoid them?

Installation

npm install -g broccoli-duplicate-watched-tree-finder

Usage

cd into a directory that contains a Brocfile.js. An example Brocfile.js with duplicate watched trees could be:

var pickFiles = require('broccoli-static-compiler'),
    compileSass = require('broccoli-sass'),
    mergeTrees = require('broccoli-merge-trees');

var app = 'app';

var styles = 'app/styles'
var styles = compileSass(styles, 'app.scss', 'assets/app.css');

module.exports = mergeTrees([app, styles]);

Then run the broccoli-duplicate-watched-tree-finder command within the directory and you will see output like:

$ broccoli-duplicate-watched-tree-finder
All watched trees:
  - app
  - app/styles

Duplicate watched trees:
 - app/styles is inside app
You should wrap the trees shown in blue in broccoli-unwatched-tree.

You can fix the problem by requiring broccoli-unwatched-tree and wrapping '/app/styles' in it:

var pickFiles = require('broccoli-static-compiler'),
    unwatched = require('broccoli-unwatched-tree'),
    compileSass = require('broccoli-sass'),
    mergeTrees = require('broccoli-merge-trees');

var app = 'app';

var styles = unwatched('app/styles')
var styles = compileSass(styles, 'app.scss', 'assets/app.css');

module.exports = mergeTrees([app, styles]);

Running the command again will now give you:

$ broccoli-duplicate-watched-tree-finder
All watched trees:
  - app

Nice! You do not have any duplicate watched paths.

Notice: The finder performs a full Broccoli build, so the command might take a few seconds to finish depending on how complex your build is.
