Website: https://contractspec.io

Typed ContractSpec lint-policy package that generates Biome presets, Grit plugins, and AI-facing rule summaries.

What It Provides

• Acts as the source of truth for repository and consumer Biome policy artifacts.
• Publishes generated presets, Grit plugins, and AI summaries alongside the typed manifest and generation helpers.
• Requires artifact synchronization whenever the typed policy manifest changes so committed outputs stay aligned.
• Enforces React and React Native compatible JSX in shared presentation packages by preferring layout primitives (HStack, VStack, Box) over raw <div> and requiring visible text to sit inside Text or approved typography components. Repository app packages are excluded by default and can be opted in with the policy allowlist.
• Related ContractSpec packages include @lssm-tech/tool.bun, @lssm-tech/tool.typescript.

Installation

npm install @lssm-tech/biome-config

or

bun add @lssm-tech/biome-config

Usage

Import the root entrypoint from @lssm-tech/biome-config, or choose a documented subpath when you only need one part of the package surface.

JSX Primitive Fixer

The Biome Grit plugins emit diagnostics only. To apply conservative native HTML replacement fixes, run:

bun run jsx:fix-primitives

or from this package:

bun run fix:jsx-primitives

By default the fixer scans packages/bundles, packages/examples, and packages/modules. It skips packages/apps unless an app is explicitly allowlisted:

bun run jsx:fix-primitives -- --allow-app web-landing

Use --check for a dry run. The fixer preserves original attributes and className by default, infers safe list props from simple class strings, rewrites generic <span> elements to inline-safe Text, maps native HTML controls to design-system controls (including the cross-platform NativeSelect family), and wraps raw text with context awareness: block-safe containers keep <Text>...</Text>, while mixed-content contexts use inline-safe <Text asChild><span>...</span></Text>. Semantic form roots remain diagnostic-only when no behavior-preserving design-system replacement exists.

Architecture

• src/policies.ts defines the typed policy manifest.
• src/generate.ts and src/sync.ts generate and synchronize derived artifacts.
• src/fix-jsx-primitives.ts provides the conservative companion codemod for deterministic JSX primitive replacements.
• src/types.ts and src/index.ts expose the public API for generation and policy consumption.
• presets/, plugins/, and ai/ contain committed generated artifacts consumed by downstream tools.

Public Entry Points

• Exports the root library API and ships generated presets, Grit plugins, and AI-facing summaries as committed package artifacts.
• Export . resolves through ./src/index.ts.

Recent Updates

• Add cross-platform JSX layout and text guardrails for React and React Native compatibility.
• Add a conservative JSX primitive fixer command for deterministic native HTML replacements.
• Replace eslint+prettier by biomejs to optimize speed.

Notes

• The committed presets/, plugins/, and ai/ artifacts are intended for downstream scaffolding without code execution.
