Getting Started

1. Run nexa_setup.bat to fetch Chromium.
2. Run nexa_minimal_cleanup.sh to clean the tree and build.
3. Optionally run mini_installer_build.sh for a distributable installer.

Ensure depot_tools is in PATH and Visual Studio 2022 is installed with C++ desktop workload.

How to Run Cleanup and Build Scripts

After you've run nexa_setup.bat and Chromium has been fetched successfully:

Step 1 — Run Cleanup Script

Make sure you're using Git Bash, WSL, or any Unix-like shell on Windows:

bash
cd Nexa-Browser
bash nexa_minimal_cleanup.sh

This script will:

• Delete unused Chromium modules and third-party directories
• Configure a minimal args.gn for optimized builds
• Generate output using gn and autoninja
• Strip the chrome binary and compress it using Brotli

The final output will be:

out/Nexa/chrome # full browser binary
out/Nexa/chrome.br # compressed version

Step 2 — (Optional) Build a Windows Installer

To generate a lightweight Windows .exe installer, run:

bash 
mini_installer_build.sh

Output installer path:

out/NexaInstaller/mini_installer.exe

Make sure GN/Ninja and all Chromium build dependencies are correctly installed before running these scripts.
