> Key: ATLAS-5346
> URL: https://issues.apache.org/jira/browse/ATLAS-5346
> Project: Atlas
> Issue Type: Sub-task
> Components: atlas-ci-build
> Affects Versions: 3.0.0
> Reporter: Prasad P. Pawar
> Assignee: Prasad P. Pawar
> Priority: Major
> Labels: build-options
>
> Optimize the Atlas React UI ({{{}dashboard/{}}}) production build by reducing
> build time, improving bundle splitting, and streamlining the Maven/npm build
> pipeline. Changes include Vite configuration updates, lazy loading of heavy
> views, removal of unused demo components from the main bundle, ESLint
> flat-config migration, and Maven frontend plugin improvements.
> h3. Problem Statement
> The React UI production build was slow and produced large monolithic bundles
> because heavy modules (Statistics, Entity Detail tabs, Administrator views,
> D3/MUI stacks) were eagerly loaded. The Maven build also copied unnecessary
> artifacts and re-downloaded toolchain dependencies on each run, adding
> overhead in local and CI builds.
> h3. Proposed Solution / Changes Implemented
> h4. 1. Vite build optimization ({{{}vite.config.ts{}}})
> * Added manual chunk splitting for {{{}react{}}}, {{{}mui{}}},
> {{{}redux{}}}, {{{}router{}}}, {{{}d3{}}}, and {{utils}}
> * Disabled compressed size reporting ({{{}reportCompressedSize: false{}}})
> for faster builds
> * Increased chunk size warning limit
> h4. 2. Lazy loading & bundle size reduction
> * Layout.tsx — lazy-load {{Statistics}} module
> * EntityDetailPage.tsx — lazy-load detail tabs (Properties, Schema, Lineage,
> Relationships, etc.)
> * AdministratorLayout.tsx — lazy-load administrator sub-views
> * Removed unused/heavy components from main bundle:
> ** Masonry demo components ({{{}MasonryCard{}}}, {{{}MasonryGrid{}}},
> {{{}MasonryDemo{}}})
> ** Standalone {{LineageLayout}} React view (lineage handled via existing tab
> flow)
> h4. 3. Statistics module refactor
> * Extracted chart rendering into {{EntityStatsChart.tsx}}
> * Moved shared utilities into {{statsUtils.tsx}}
> * Updated related tests
> h4. 4. Build tooling & dependencies ({{{}package.json{}}},
> {{{}package-lock.json{}}})
> * Upgraded Vite {{{}6.4.3{}}}, {{@vitejs/plugin-react-swc}} {{{}4.3.1{}}},
> ESLint {{10.5.0}}
> * Migrated from {{.eslintrc.cjs}} to flat config ({{{}eslint.config.js{}}})
> * Added build scripts: {{{}build:lineage{}}}, {{{}build:legacy{}}},
> {{build:check}}
> * Separated typecheck from build using {{tsconfig.build.json}} (excludes
> test files)
> * Added platform-specific optional dependencies for Rollup, esbuild, and SWC
> * Updated npm overrides for transitive security pins ({{{}d3-color{}}},
> {{{}lodash{}}}, {{{}minimatch{}}}, etc.)
> * Added {{.npmrc}} for faster installs ({{{}prefer-offline{}}},
> {{{}audit=false{}}}, etc.)
> h4. 5. Maven / CI build pipeline ({{{}dashboard/pom.xml{}}}, root
> {{{}pom.xml{}}})
> * Build directly from {{dashboard/}} module root (dashboardv2-style)
> * Persist frontend toolchain under {{.frontend-toolchain/}} to avoid
> re-downloading Node on every build
> * Configurable npm cache directory for CI
> * Simplified WAR resource packaging to use {{dashboard/dist}} directly
> * Added {{ensure-lineage-build.mjs}} for separate lineage asset build step
> * Improved {{ensure-native-deps.mjs}} with fast-path for already-installed
> native binaries
> h4. 6. TypeScript config
> * Updated {{tsconfig.json}} and {{tsconfig.build.json}} for production-only
> type checking
