This is a imageoptim-cli hook for pre-commit. This optimised images on commit.

• To use this you first need to install pre-commit(see links below).
• Then create a pre-commit config file.
• Run pre-commit install from the root of your project
• Download ImageOptim for Mac.
• Additionally download ImageAlpha and JPEGmini for Mac

Finally add this to your .pre-commit-config.yaml:

   -   repo: https://github.com/awebdeveloper/pre-commit-imageoptim
       rev: '' # Use the sha or tag you want to point at like 0.0.1
       hooks:
       -   id: imageoptim
           additional_dependencies: ['imageoptim-cli']

PS: These are for version 2.3.0 visit https://pre-commit.com/#2-add-a-pre-commit-configuration for latest config syntax or for config syntax specific to your version

Now everytime you commit a png/jpg file. It will run imageoptim-cli on this and optimise the file.

1. Why does pre-commit say failed everytime the images are changed by the file.

A. This is how pre-commit works. You need to just add the files again and commit. This is done so that you can verify the changes.

2. Why only mac.

A. Imageoptim is only on mac, if and when it does add other platform we will support it.

3. How to pass Pass extra args

A. Read precommit docs on how to use args property.
