Step 1: clone repo

Heads-up: please use SSH authentication and sign commits using GnuPG.

$ git clone git@github.com:superbacked/superbacked.git

Step 2: install Homebrew

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

$ uname -m | grep arm64 && echo 'export PATH=$PATH:/opt/homebrew/bin' >> ~/.zshrc && source ~/.zshrc

Step 3: install Node.js

$ brew install node@22

$ echo 'export PATH=$PATH:/opt/homebrew/opt/node@22/bin' >> ~/.zshrc && source ~/.zshrc

Step 4: install Visual Studio Code

Heads-up: installing Prettier - Code formatter and ESLint extensions is recommended.

Step 5: install dependencies

Heads-up: using --ignore-scripts is recommended to prevent third-party postinstall scripts from executing arbitrary code on host.

$ npm install --ignore-scripts

Step 6: install Electron binary

Heads-up: because --ignore-scripts was used in step 5, Electron’s postinstall script (which downloads and extracts the platform-specific binary to node_modules/electron/dist/) must be run manually. Without this step, npm run code fails with Electron failed to install correctly. Re-run this step whenever node_modules/electron is recreated (for example, after an Electron version bump).

$ node node_modules/electron/install.js

Step 7: run app in development mode

$ npm run code
