I am working on Module that require quick fix. As I assume I can fix this by creating Magento 2 Patch way.

I never created a Patch file before, Can anyone help me How can I create Patch file for custom module.?

Any link, information appreciated



I use this method for creating patch, hope it helps . Let suppose you will modify this file


Create a copy of that file with your changes on it:


What you need to do is run this command:

diff -u CustomerData.php CustomerDataModified.php > diff.patch

Move diff.patch in your root under a directory, example Mypatches dir . Delete the file added CustomerDataModified.php since the patch is generated with the changes.

Here comes the tricky part , needs some manual modification now : When you open the diff.patch you will get something like this on the top :

--- CustomerData.php    2018-02-21 01:26:16.000000000 -0500
+++ CustomerDataModified.php    2019-01-03 03:57:47.326011737 -0500

Replace those line with this one:

diff --git a/Block/CustomerData.php b/Block/CustomerData.php
index 3ee2rd..8349152 111644
--- a/Block/CustomerData.php
+++ b/Block/CustomerData.php

The index is needed (the numbers are generated by me random, by default are generated from git but in most cases the vendor is in .gitignore)

Next Step is modification of the composer.json in the root of your magento : Add the extra section (if you dont have one already)

"extra": {
        "magento-force": "override",
        "patches": {
            "magento/module-customer": {
                "some description abt issue applying this patch": "Mypatches/diff.patch"

And there you go . Your patch is diff.patch (you can call whatever you like ) . Run composer install to apply that

Here is my answer, i hope it will help someone:

First make sure that this package is installed via composer: cweagans/composer-patches

Lets say you want to apply a patch from a third-party module installed via composer for a controller. Please make sure that you have this part in the composer.json file:

"extra": {
    "magento-force": true,
    "composer-exit-on-patch-failure": true,
    "patches": {
        "vendorname/module-somerandomname": {
            "Description here": "patches/my_patch_name.patch"

Assuming that your vendor folder is in the .gitignore file, you can still do:

  1. git add -f vendor/vendorname/module-somerandomname/Controller/Myfile.php
  2. Do your changes to the Myfile.php
  3. Do a git diff vendor/vendorname/module-somerandomname/Controller/Myfile.php > patches/my_patch_name.patch
  4. git restore --staged vendor/vendorname/module-somerandomname/Controller/Myfile.php
  5. Do a composer install

For creating a patch, most of the people are using Github

At git, it is easy to create a patch for a commit. If you want to create the patch for a commit 452 then use git format-patch -1 {commitId}
