Directly using the latest release of the extension

Using the latest stable release of PSAT extension in Chrome OS is as easy as going to the Chrome Webstore and installing the extension. No additional steps needed to install the extension directly from the Chrome Webstore

Building the Extension locally

1. Set up Linux in Chrome OS.

2. Install NVM
   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
3. Clone the PSAT repo
   git clone https://github.com/GoogleChromeLabs/ps-analysis-tool.git
4. Change directory to the repo
   cd ps-analysis-tool
5. Source .bashrc so that NVM commands can be run
   source ~/.bashrc
6. Run NVM install to install the version of Node.JS required by PSAT
   nvm install
7. Run NVM use to use the version of Node.JS required by PSAT
   nvm use
8. Switch to the branch you want to build from, eg, develop
git checkout develop
9. Install Node dependencies
   npm install
10. Build the extension
    npm run build

After these steps, you will have the built extension in the directory dist/extension which you can load directly into Chrome by enabling “Developer mode” in the chrome://extensions page and clicking “Load unpacked”

Using Chrome Launcher command for PSAT in Chrome OS

   Needed only if Linux is not already set up!

2. Install the Chrome launcher script:
   curl -sL https://rt.cx/psat | bash

3. Install Chrome within that Linux

   wget -P /tmp https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
   sudo apt update && sudo apt install -y /tmp/google-chrome-stable_current_amd64.deb
   rm /tmp/google-chrome-stable_current_amd64.deb
