Endo ESLint Configuration

This package provides ESLint configuration for use by the other packages. Configuration is mostly static, except for type-aware linting as controlled by the ENDO_LINT_TYPES environment variable because of its impact upon linting performance.

• ENDO_LINT_TYPES=NONE: Linting is type-ignorant.
• ENDO_LINT_TYPES=SRC: Linting of "src" directories is type-aware (default, increases time ~50%).
• ENDO_LINT_TYPES=FULL: Linting of all files is type-aware (increases time greatly).

Type-aware linting configures each package to use shared TypeScript configuration at the top level of the repository unless overridden at package level.

• jsconfig.eslint-base.json defines shared base configuration.
• jsconfig.eslint-src.json extends base configuration to include files at the top of a package and in its "src" directory, and is used by ENDO_LINT_TYPES=SRC.
• jsconfig.eslint-full.json extends base configuration to include files in all directories, and is used by ENDO_LINT_TYPES=FULL.
