How to choose the right framework?

Brief Answer

• Start with product goals and constraints: SPA vs SSR, mobile, time‑to‑market.
• Assess the team: current experience, hiring availability, learning curve.
• Check ecosystem: docs, stability, plugins, community, bus factor.
• Consider performance and SEO: SSR/SSG, hybrid rendering, caching.
• Verify long‑term support: releases, compatibility, migrations.
• Build a small spike and compare DX (routing, state, build).

Key criteria

• Product fit: SPA/SSR/SSG, i18n, SEO, accessibility, integrations.
• Team fit: team skills, talent availability, onboarding speed.
• Ecosystem: mature state/forms/fetch libs; documentation and examples.
• Performance: bundle size, SSR/SSG, progressive hydration, CDN caching.
• Maintainability: API stability, release cadence, migration path, LTS.
• Tooling: build, tests, types, linters, DevTools, monitoring.

Fast decision flow

1. Create a shortlist (2–3 options) using the criteria above.
2. Run a spike: tiny prototype with a page, routing, and a fetch.
3. Measure: TTI, CLS, bundle size, and developer experience.
4. Assess risks: lock‑in, migration complexity, bus factor.
5. Choose a “good‑enough” option, document assumptions, plan a review.

Common pitfalls

• Picking by hype instead of requirements.
• Ignoring ecosystem and long‑term support.
• Over‑engineering for hypothetical scale.
• Over‑trusting generators/abstractions without constraints.

Mini examples

• Rich SPA UI: React or Vue; simplicity — Svelte.
• SSR and SEO: Next.js or Nuxt; content — Astro.
• Mobile: React Native (JS) or Flutter (Dart).

Recommendations

• Formalize criteria and metrics; compare on a prototype.
• Prefer mature frameworks with active ecosystems and a clear roadmap.
• Plan migrations: strategies, feature flags, compatible APIs.
