Feature: Optimize Application Bundle Size to Under 512KB

[Tooonia]

Description:

• Problem: The current application bundle size is 647KB, which exceeds the target budget of 512KB by 135KB. This negatively impacts the initial loading performance.

• Goal: Reduce the initial bundle size to below 512KB and improve loading performance.

Tasks:

• Phase 1: Analysis & Baseline : Install webpack-bundle-analyzer and generate a baseline analysis to document the current state.

• Phase 2: Material Design Optimization : Replace full Material imports with specific, tree-shakable imports to reduce bundle size.

• Phase 3: Lazy Loading Optimization : Implement lazy loading for routes and change the preloading strategy to improve initial load times.

• Phase 4: Polyfills Optimization : Audit and remove unnecessary polyfills and use modern browser targeting.

• Phase 5: Code Splitting & Tree Shaking : Split large components, use dynamic imports, and optimize tree shaking to further reduce bundle size.

• Phase 6: CSS/SCSS Optimization : Optimize the component's large SCSS file and implement CSS purging to remove unused styles.

• Phase 7: Testing & Validation : Perform a final bundle analysis and performance tests to validate improvements.

Success Criteria:

• Bundle size < 512KB.

• Initial load time < 3 seconds.

• The application's functionality is not broken.
