Local Image Optimizer Add-on

A Local add on for compressing images on your WordPress site. This repository hosts the source code; if you simply want to use the add-on, download the latest version of local from the release page and install the add-on within the app.

Currently this add-on performs lossy compression with jpeg-recompress. It is planned to expand this in the future to leverage more tools that do things like lossless compression.

Manual Installation & Development setup

If you haven't already, it is advised that you familiarize yourself with the basics of electron.

Clone

Clone the repository into one of the following directories depending on your platform:

You need to replace 'Local' with 'Local Beta' in the above paths if you want to create the add-on for Local Beta.

If you prefer to clone your source code elsewhere, you can do so and then symlink that directory to one in the above mentioned directories.

An example of this on MacOS would look like:

git clone [email protected]:getflywheel/local-addon-image-optimizer.git ~/code

ln -s ~/code/local-addon-image-optimizer ~/Library/Application Support/Local/addons

Install Add-on Dependencies

yarn install or npm install

Build

This add-on utilizes tsc to compile the Main thread code and webpack to compile the Renderer thread code.

to compile both at the same time run:

yarn build

Otherwise you can compile the main thread code with:

yarn build-main

Or the renderer thread code with:

yarn build-renderer or yarn watch-renderer

Add Add-on to Local

  1. Clone repo directly into the add-ons folder (paths described above)
  2. yarn install or npm install (install dependencies)
  3. yarn build or npm run build
  4. Open Local and enable add-on

If the enabling the add-on via the Local UI doesn't work for some reason, you can also enable it by updating the file enabled-addons.json. This is located at one of the following application specific paths.

You'll want to make sure that the json file includes:

"@getflywheel/local-addon-image-optimizer": true

External Libraries

It is worth noting the the TS definitions for this module are exposed and publicly availble. The actual code is injected once the add-on is loaded by Local. This can make writing tests a little tricky as the @getflywheel/local/<main/renderer> module isn't available outside of Local (ie testing unit testing environments). The best option is to mock out this module while running tests.

Folder Structure

All files (other than test files) in /src will be transpiled to /lib using TypeScript. Anything in /lib will be overwritten.

vendor contains compiled binaries namespaced under the appropriate operating system name.

Development Workflow

For additional context and insight, you can consult the Local add-on API, which provides a wide range of values and functions for developing your add-on.
