Initial setup

[paescuj]

Initial setup for @directus/eslint-config - a ESLint config preset which can be used across all JavaScript repos within the Directus organization for a simple setup and consistent linting & formatting experience.

---

• The preset is heavily inspired and partially based on Anthony's ESLint config preset (https://github.com/antfu/eslint-config), while leveraging preferences from the Directus ecosystem
  • Format code without Prettier for more flexible code structuring, see https://antfu.me/posts/why-not-prettier
  • Adopted some of the configs
• Support for formatting and linting of other files besides code (json, md, ...) via ESLint, formatting is using dprint
• Old lint rules have been adopted from directus/directus → .eslintrc.js
• Old format rules have been adopted from directus/directus → .prettierrc.json
• It's leveraging the flat config format, which is the new default since ESLint v9

---

• Repo is dogfooding, which helps to verify the setup
• Can be inspected via pnpm run inspect
• Included workflows:
  • Check: Lint, Typecheck, Test
  • Release: Create new version by dispatching this workflow
