LuminaJS

Product Requirements Document (PRD): LuminaJS​

A next-gen JavaScript framework combining the best of React, Vue, Svelte, Rails, and Astro

1. Overview & Purpose​

  • Vision: Enable developers to build high‑performance, maintainable, and accessible web applications with minimal configuration and maximal flexibility.
  • Name: LuminaJS ("light" + "unify")
  • Tagline: "Compile brilliance, ship lightning."

Problem Statement: Existing frameworks force trade‑offs between runtime vs compile‑time, configuration vs convention, granularity vs global state. LuminaJS unifies declarative UI, compile‑time optimizations, progressive adoption, batteries‑included conventions, and partial hydration islands architecture.

2. Target Audience & Use Cases​

  • Audience: Frontend teams at startups and enterprises; individual developers seeking productivity.

  • Use Cases:

    • Single‑Page Applications (SPAs)
    • Multi‑Page Apps (MPAs) with partial hydration
    • Content‑heavy marketing sites
    • Dashboard & real‑time apps

3. Key Goals & Success Metrics​

4. Core Principles & Philosophies​

  1. Declarative & Reactive UI

    • Leverage a lightweight Virtual DOM with fine‑grained diffing inspired by React.

  2. Compile‑Time Optimizations

    • Svelte‑style compilation: strip unused code, inline reactive updates before shipping to browser.

  3. Progressive Adoption

    • Incremental integration: drop‑in components, opt‑in features, gradual migration from vanilla JS.

  4. Convention over Configuration

    • Opinionated folder structure and sensible defaults inspired by Rails; minimal boilerplate.

  5. Islands Architecture

    • Hydrate only interactive components ("islands") on demand, à la Astro, to boost performance.

5. High-Level Feature List​

  • Component Model:

    • .lum single‑file components (HTML + JS + scoped CSS)
    • JSX/TSX support out of the box

  • Reactive State:

    • signal() primitives for local and global stores
    • Context API for dependency injection

  • Routing & Data:

    • File‑based routing with nested layouts
    • Built‑in data loaders with caching and invalidation

  • CLI & Tooling:

    • lumina create scaffold, lumina dev hot‑reload, lumina build optimized bundles
    • Plugin system for custom transforms (e.g., GraphQL, Markdown)

  • Server‑Side Rendering (SSR):

    • Zero‑config SSR with streaming support

  • Partial Hydration:

    • Mark components as client or server; hydrate on interaction

  • State Management:

    • Built‑in global store with snapshot testing support

  • Security & Accessibility:

    • CSP‑friendly default builds
    • Auto‑generate aria attributes and linting checks

Runtime vs Compile

  • Compile Stage:

    • Parse .lum files, extract template, script, style.
    • Generate optimized JS modules with inlined reactivity.
    • Tree‑shake unused utilities and CSS.

  • Runtime Layer:

    • Virtual DOM diff engine for minimal patches.
    • Hydration controller for islands.
    • Dev‑only diagnostics & warnings.

7. Developer Experience (DX)​

  • Onboarding:

    • Guided CLI wizard (lumina init)
    • Interactive docs with embedded code and live playground

  • Tooling Integration:

    • First‑class TypeScript support
    • ESLint, Prettier, and IDE extensions pre‑configured

  • Error Handling:

    • Human‑readable stack traces with source maps
    • Inline hints in console for common mistakes

8. Extensibility & Ecosystem​

  • Plugin API:

    • Hooks into compile and dev server phases
    • Marketplace for community plugins (e.g., i18n, PWA, GraphQL)

  • Theme System:

    • CSS variables and design tokens baked in
    • Tailwind CSS integration plugin

9. Security, Performance & Accessibility​

  • Security:

    • HTML escaping by default in templates
    • CSP meta‑tag injection

  • Performance:

    • Lazy loading of islands
    • Automatic code splitting per route
    • Built‑in image and asset optimization

  • Accessibility:

    • ARIA attribute inference in components
    • Lighthouse integration for CI checks

10. Roadmap & Milestones​

  1. Alpha (3 months): Core compiler, Virtual DOM, Signal API, CLI scaffold
  2. Beta (6 months): SSR, routing, partial hydration, official docs
  3. v1.0 (12 months): Plugin marketplace, enterprise features, stable API

Next Steps:

  • Validate with early adopters (surveys, interviews)
  • Prototype hello‑world demo and gather performance benchmarks
  • Build documentation site and sample applications
