Jest

This is the pnpm package manager — a fast, disk-space-efficient alternative to npm and yarn for managing Node.js dependencies. It uses a content-addressable file store with hard links to avoid duplicating packages across projects, and enforces a strict, non-flat node_modules structure that prevents phantom dependency access.

Coding Conventions

Standards and patterns used in this codebase

api-patterns

API routes are organized in routes/ directory

New endpoints go in cache/api/src/cacheDelete.ts/routes/

cache/api/src/cacheDelete.tscache/api/src/index.ts

naming

File naming uses: kebab-case, camelCase

commitlint.config.cjs, eslint.config.mjs, index.d.ts, typed.d.ts, bundle.ts

commitlint.config.cjseslint.config.mjs__typings__/index.d.ts

code-style

TypeScript is the primary language

All new files should be .ts or .tsx

__typings__/index.d.ts__typings__/typed.d.tspnpm/bundle.ts

configuration

Configuration is centralized in config files

Config files: commitlint.config.cjs, eslint.config.mjs

commitlint.config.cjseslint.config.mjs__utils__/eslint-config/index.js

module-exports

Use index.ts barrel files to export module public API

Each module has index.ts that re-exports public functions

__utils__/eslint-config/index.jsworker/src/index.tsbuilder/policy/src/index.ts

typescript

Types are defined in dedicated type files

Type files: __typings__/index.d.ts, __typings__/typed.d.ts
