What is data-table-filters CLAUDE.md?

Project-specific instructions for working on a React data-table system in a monorepo, a repository containing several related projects. They document the project structure, commands, and database setup using pnpm, Turborepo, Drizzle, and Postgres.

Use them when developing, testing, linting, building, formatting, migrating the database, or adding registry components in this project.

They reduce the time spent discovering how the repository is organised, how to run checks, and how database-dependent tests behave without a database connection.

About the project

openstatusHQ/data-table-filters is a React toolkit for building data tables with filters, sorting, scrolling, and reusable table components. It helps developers create filterable tables using shadcn/ui and TanStack Table. The catalogue add-ons provide table blocks, state adapters, cell renderers, query integration, and other parts of its workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01088	$0.01088
Opus 5.5	$0.00435	$0.00435
Sonnet 5.5	$0.00218	$0.00218
Haiku 4.5	$0.00109	$0.00109

Security

Grade A, and why

data-table-filters CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project overview

data-table-filters — a React data table system with faceted filters, sorting, infinite scroll, and virtualization. Delivered as shadcn registry blocks installable via npx shadcn@latest add.

Monorepo structure (pnpm + turborepo)

apps/web — Next.js app (docs site + demo). Uses App Router.
packages/registry — the shadcn registry source (components, utilities, Drizzle helpers)
packages/tsconfig — shared TS configs

Key commands

pnpm dev              # start all workspaces
pnpm build            # turbo build (includes registry:build)
pnpm lint             # turbo lint (eslint across workspaces)
pnpm typecheck        # tsc --noEmit across workspaces
pnpm test             # turbo test (vitest across workspaces)
pnpm format           # prettier --write .
pnpm registry:build   # build shadcn registry artifacts

Database

Drizzle ORM with Postgres (Supabase)
DB-dependent tests run in CI only (Postgres service container in GitHub Actions)
Tests use describe.skipIf(!hasDatabase) — they skip gracefully without DATABASE_URL
Migrations: pnpm --filter web db:drizzle:migrate
Seed test data: pnpm --filter web db:drizzle:seed-test

Coding standards

Before every commit, run local checks

The pre-commit hook (.claude/hooks/pre-commit-checks.sh) runs automatically before git commit. It enforces:

pnpm prettier --check . — format check (fix with pnpm format if needed)
pnpm turbo lint — eslint
pnpm turbo typecheck — tsc --noEmit
DATABASE_URL= pnpm turbo test — vitest (non-DB tests only)

If any step fails, fix it before committing. Do not use --no-verify or skip hooks.

After pushing, verify CI

DB-dependent tests (Drizzle integration tests) only run in GitHub Actions CI where Postgres is available. After pushing a branch or opening a PR, check CI status with gh run list or gh pr checks. If DB tests fail in CI, fix locally and push again.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
