depatcher

Programmatically create and apply .patch files to your project's dependencies.
Under the hood, it leverages diff to generate diffs and package manager primitives to apply them.

Note: diff is bundled to support the patch cross package managers.

⚙️ Installation

Install as a development dependency:

Package Manager	Command
npm	npm install -D depatcher
yarn	yarn add -D depatcher
pnpm	pnpm add -D depatcher

📖 Usage

createPatch

Generates a .patch file by comparing an original file with a modified (patched) file.

import{createPatch}from'depatcher'createPatch('./original_file.js','./patched_file.js','./file.patch')

applyPatch

Applies .patch files to specific file paths within a target dependency.

import{applyPatch}from'depatcher'// applyPatch(packageName, patchMap)awaitapplyPatch('packageName',{// 'target_file_in_dependency': 'path_to_patch_file''/dist/index.js': './packageName_index.patch'})

applyPatchMultiple

Applies .patch files to multiple target dependencies efficiently.

import{applyPatchMultiple}from'depatcher'// applyPatchMultiple(packagePatchMap)awaitapplyPatchMultiple({packageName1: {'/dist/index.js': './packageName1_index.patch'},packageName2: {'/dist/index.js': './packageName2_index.patch'}})
