Documentation & Knowledge Base Checklist for Web Development

Document who you serve (frontend consumers, backend integrators, SREs) and their top tasks, then prioritize content that unblocks those paths first. Clear audience scope prevents generic docs that do not answer real developer questions.

Organize the sidebar and landing pages by jobs-to-be-done, service, and environment (local, staging, production). A task-based IA shortens the path from search to solution for busy engineers.

Adopt a static site generator like Docusaurus or MkDocs Material, store sources in Git, and enforce a single publishing pipeline. One toolchain minimizes drift and keeps contributions familiar across repos.

Include quickstart, environment setup, run scripts, architecture overview, and support channels, plus status badges. Consistent READMEs reduce setup time for new contributors and reviewers.

Use a lightweight template like MADR to capture architecture decisions, context, and consequences. ADRs prevent recurring debates and give newcomers a fast way to learn why things are the way they are.

Publish a shared vocabulary and include Mermaid or PlantUML diagrams for flows and data models. A clear domain language reduces misinterpretations across services and teams.

Provide CONTRIBUTING.md, CODE_OF_CONDUCT, and .github issue and PR templates with doc-specific checklists. Templates make expectations explicit and improve doc review quality.

Keep an OpenAPI 3.1 spec in the repo and validate it in CI with Spectral or Redocly CLI. Source-of-truth specs prevent drift between code, SDKs, and docs.

Generate reference docs with Redocly, Stoplight, or Swagger UI and deploy on each merge. Automated publishing ensures consumers always see the current schema.

Include x-examples in OpenAPI and Postman collections with Newman tests that run in CI. Tested examples prevent drift and reduce support tickets.

Explain OAuth2 flows, JWT lifetimes, refresh logic, and CSRF handling, with sequence diagrams. Auth is where most integrators get blocked, so clarity here pays off.

Publish a reusable error envelope with a code catalog, links to remediation, and RFC references. Consistent errors improve debuggability across microservices.

Expose ER diagrams, migration policies, and rollback steps, ideally generated from Prisma or ORM schemas. Clear DB docs reduce risky changes and late surprises.

Publish SDL with field descriptions, deprecation reasons, and federation notes, and run GraphQL Inspector in CI. Schema checkers catch breaking changes before consumers do.

Generate prop tables from TypeScript (react-docgen-typescript) and write usage in MDX with live examples. Storybook becomes a living contract between design and engineering.

Publish token sources (JSON, CSS variables) and theming guidelines, plus Tailwind or CSS-in-JS conventions. Token docs prevent inconsistent UI and reduce hard-coded styles.

Include checklists for focus order, color contrast, and ARIA, and run axe and keyboard tests in CI. A11y docs make compliance measurable and repeatable.

Explain patterns for React Router, Next.js app router, and state tools like Redux or Zustand, with anti-patterns called out. Pattern docs keep codebases consistent across teams.

Set budgets for LCP, CLS, and TBT, and document how to measure with Lighthouse CI and WebPageTest. Performance docs turn vague goals into enforceable thresholds.

Describe i18n file structure, message extraction, and translation review with i18next or FormatJS. Clear i18n docs avoid runtime surprises in non-default locales.

Publish Browserslist targets, known quirks, and required polyfills, with links to caniuse data. A written policy prevents churn and unpredictable breakage.

Use GitHub Actions or GitLab CI to build Docusaurus or MkDocs, run link checks, and push to a static host. Automated deploys keep docs timely and verifiable.

Add markdownlint, remark-lint, and Vale to enforce style, headings, and inclusive language. Linting catches issues before review and ensures consistency at scale.

Run snippets with tools like eslint-plugin-markdown, embedme, or custom Jest harnesses. Executed snippets prevent rot and increase developer trust.

Enforce commit linting and use semantic-release to generate release notes that link to docs and issues. Automated changelogs reduce manual work and errors.

Use branch or tag-based doc versions, add deprecation banners, and maintain URLs like /v1 and /v2. Versioned docs serve legacy consumers without confusion.

Integrate Algolia DocSearch or Elastic and track zero-result queries. Search analytics reveal content gaps you can fix quickly.

Offer printable exports with Puppeteer or wkhtmltopdf for teams that need offline review. This helps in regulated environments and partner onboarding.

Publish day 1 to day 7 guides with environment setup scripts, dotfiles, access steps, and sample tasks. Role-based runbooks reduce manager time and new-hire thrash.

Provide escalation paths, comms checklists, and a post-incident template with action item owners. Standardized runbooks improve MTTR and learning loops.

Map pages and repos to CODEOWNERS groups and enforce review rules with protected branches and SSO. Clear ownership keeps content fresh and reduces stale pages.

Add review dates, doc owners, and a scheduled job that flags stale pages with issues or labels. Lifecycle tracking prevents outdated advice from lingering.

Create rules for deep-link anchors, canonical links, and service-to-service references. Strong linking improves discoverability and reduces duplicate explanations.

Track page views, time to first success, search exits, and feedback ratings using GA4 or Plausible. KPIs make doc quality measurable and guide prioritization.

Publish PII classification, data retention, cookie policies, and secure coding guidance for web endpoints. Clear rules reduce risk and speed security reviews.
