What is broccoli-merge-trees?
The broccoli-merge-trees npm package is used to merge multiple Broccoli trees into a single tree. This is useful in build processes where you need to combine outputs from different sources or plugins into one cohesive output.
What are broccoli-merge-trees's main functionalities?
Basic Merge
This feature allows you to merge two or more trees into a single tree. The code sample demonstrates merging two trees located at 'path/to/tree1' and 'path/to/tree2'.
const mergeTrees = require('broccoli-merge-trees');
const tree1 = 'path/to/tree1';
const tree2 = 'path/to/tree2';
const mergedTree = mergeTrees([tree1, tree2]);
Overwrite Option
This feature allows you to specify whether files in later trees should overwrite files in earlier trees. The code sample demonstrates merging two trees with the overwrite option set to true.
const mergeTrees = require('broccoli-merge-trees');
const tree1 = 'path/to/tree1';
const tree2 = 'path/to/tree2';
const mergedTree = mergeTrees([tree1, tree2], { overwrite: true });
Annotation
This feature allows you to add an annotation to the merged tree for easier debugging and logging. The code sample demonstrates merging two trees with an annotation 'Merged Trees'.
const mergeTrees = require('broccoli-merge-trees');
const tree1 = 'path/to/tree1';
const tree2 = 'path/to/tree2';
const mergedTree = mergeTrees([tree1, tree2], { annotation: 'Merged Trees' });
Other packages similar to broccoli-merge-trees
broccoli-concat
The broccoli-concat package is used to concatenate multiple files into a single file. While broccoli-merge-trees combines entire trees, broccoli-concat focuses on combining file contents. This can be useful for tasks like combining JavaScript or CSS files.
broccoli-funnel
The broccoli-funnel package allows you to filter and move files within a tree. It provides more granular control over the contents of a tree compared to broccoli-merge-trees, which merges entire trees. This can be useful for tasks like copying specific files or directories.
broccoli-stew
The broccoli-stew package offers a collection of Broccoli plugins for various tasks, including file manipulation, logging, and debugging. It provides more specialized functionalities compared to the general tree merging capabilities of broccoli-merge-trees.
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);
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.
