Phase 0: Research

Testing Strategy

Decision: Use Vitest for unit testing Astro components and Playwright for end-to-end testing.

Rationale:

Vitest: It's a fast and modern test runner that's compatible with Vite, which Astro uses under the hood. It's easy to set up and has a similar API to Jest.
Playwright: It's a powerful end-to-end testing framework that allows testing across different browsers. It's great for simulating user interactions and verifying the complete functionality of the site.

Alternatives considered:

Jest: A popular testing framework, but Vitest is more modern and better integrated with the Vite ecosystem.
Cypress: Another popular end-to-end testing framework, but Playwright has better cross-browser support.

Performance Goals

Decision: Aim for a Google Lighthouse score of 90+ for Performance, Accessibility, Best Practices, and SEO.

Rationale: This is a widely accepted benchmark for web performance and user experience. Achieving these scores will ensure a fast and accessible website.

Alternatives considered: None, as this is a standard best practice.

Constraints

Decision: The project should be completed within 3 months and stay within a budget of $10,000.

Rationale: These constraints are based on the client's requirements.

Alternatives considered: None.

Scale/Scope

Decision: The initial scope is to migrate the existing content from the old site to the new Astro and Payload CMS setup. This includes ~50 blog posts and ~20 portfolio items.

Rationale: This is based on the analysis of the existing sitemap and CMS structure.
