Entry Points

| Entry | Feature Root | Entry Points | Description | | ----------------------- | ------------------------------ | ----------------------- | ----------------------------- | | @yasainet/eslint/next | src/features/ | - | Common rules + Next.js | | @yasainet/eslint/node | scripts/features/ | scripts/commands/*.ts | Common rules (CLI scripts) | | @yasainet/eslint/deno | supabase/functions/features/ | - | Common rules (Edge Functions) |

Directory Structure

src/
├── common/   # Shared rules for all environments
├── next/     # Next.js-specific rules (hooks, components, directives)
├── node/     # Node.js CLI scripts (scripts/features, scripts/commands)
└── deno/     # Deno entry point (entry-point boundary, _utils boundary, _lib boundary)

Each entry point enforces a feature-based architecture with the following convention in consuming projects:

{featureRoot}/
├── {feature}/
│   ├── actions/        # *.action.ts — entry points (handleXxx)
│   ├── services/       # *.service.ts — business logic
│   ├── repositories/   # *.repo.ts — data access
│   ├── types/          # *.type.ts
│   ├── schemas/        # *.schema.ts
│   ├── utils/          # *.util.ts
│   └── constants/      # *.constant.ts
├── shared/             # Cross-feature shared modules
├── ...
{libRoot}/              # *.lib.ts — library wrappers (e.g., supabase.lib.ts)
{utilsRoot}/            # *.util.ts — top-level utilities

import nextTs from "eslint-config-next/typescript";

export default defineConfig([
  ...nextVitals,
  ...nextTs,
  // Override default ignores of eslint-config-next.

Release

Version is derived from the Git tag. CI automatically sets package.json version before publishing.

1. Commit and push to main
2. Create and push a tag:

git tag v1.0.0
git push --tags

3. GitHub Actions will automatically publish to npm
