@factory/config

Shared toolchain configuration for AI Software Factory. One source of truth for compiler strictness, Prettier, and ESLint so the 11 packages + 2 apps + 2 test suites never drift from each other.

Source-first: main/types point at src/index.ts — no build step. A tsc → dist/ build is part of the Phase 0 completion checklist.

Usage

// apps/web/eslintrc.json (legacy eslintrc, like the root)
{
  "root": true,
  "parser": "@typescript-eslint/parser",
  "extends": [/* same extends as the base */],
  "rules": { /* app-specific overrides only */ }
}

// a tool that needs the shared settings
import { baseCompilerOptions, newPackageTsconfig } from "@factory/config";
console.log(baseCompilerOptions.target); // "ES2022"

Adding a new package: copy packages/shared/tsconfig.json (one extends line) — the compiler options are already pinned by the root.

What is pinned (strictness)

• strict, noUncheckedIndexedAccess, exactOptionalPropertyTypes, noImplicitOverride (see tsconfig.base.json — an exact mirror of the root)
• ES2022 target, NodeNext module + resolution (relative ESM imports use .js specifiers — e.g. import { LIMITS } from "./constants.js").
• Prettier: double quotes, semicolons, trailingComma: "all", 100 cols.
• ESLint: eslint:recommended + @typescript-eslint/recommended + prettier compat; no-eval family hard errors (AGENTS.md: formulas never run as JS); any is a warning.

ROADMAP phases that build on this

• Phase 0 (Foundation): this package is the foundation — CI (lint → typecheck → unit → integration → build → security scan → E2E) consumes these settings.
• All phases 1–15: any new package/app inherits the same strictness; the per-package tsconfigs in this repo are the living examples.

Notes

• The root currently uses legacy .eslintrc.json (per the existing scaffold); eslint.base.js matches that format. Migrating the repo to ESLint flat config is a Phase 0 cleanup, not part of this package's surface.
• @typescript-eslint/* is a devDependency of the ROOT (hoisted by pnpm); this package intentionally adds no runtime deps.
