cd BICO-bulk-image-converter-optimizer-tool

Install dependencies

npm install

Start the Electron Project in Windows

npm run electron:start

Project will open in window mode not in browser as normal react app would, Happy Hacking!

Deployment

Deployment is never been easy before, package.json is already configured for every platform (Window, Linux, MacOs). Just need to run build commands for each platform as follows:

For Windows

npm run electron:package:win

Produces NSIS installers for both x64 and arm64.

For Linux

npm run electron:package:linux

For MacOS

npm run electron:package:mac

Running these commands will give you a package file (Windows->NSIS .exe) || (Linux->.deb) || (macOS->.dmg).
