# React
cd ReactFoodFacts && pnpm run dev

# Svelte
cd SvelteFoodFacts && pnpm run dev

# SolidJS
cd SolidFoodFacts && pnpm run dev

# Lit
cd LitFoodFacts && pnpm run dev

Build for Production

# Angular
cd AngularFoodFacts && pnpm exec ng build

# React
cd ReactFoodFacts && pnpm run build

# Svelte
cd SvelteFoodFacts && pnpm run build

# SolidJS
cd SolidFoodFacts && pnpm run build
