Install and configure

The plugin targets ESLint flat config (ESLint v9+). All rules require type information, so you must also configure @typescript-eslint.

Install

npm

npm install --save-dev @antithrow/eslint-plugin typescript-eslint

Yarn

yarn add --dev @antithrow/eslint-plugin typescript-eslint

pnpm

pnpm add --save-dev @antithrow/eslint-plugin typescript-eslint

Bun

bun add --dev @antithrow/eslint-plugin typescript-eslint

Minimal flat config

// eslint.config.ts
import tseslint from "typescript-eslint";
import antithrow from "@antithrow/eslint-plugin";

export default tseslint.config(
	...tseslint.configs.recommendedTypeChecked,
	{
		languageOptions: {
			parserOptions: {
				projectService: true,
				tsconfigRootDir: import.meta.dirname,
			},
		},
	},
	antithrow.configs.recommended,
);

antithrow.configs.recommended enables all three rules at the defaults:

Rule	Severity
@antithrow/no-throwing-call	warn
@antithrow/no-unsafe-unwrap	warn
@antithrow/no-unused-result	error

Tuning individual rules

{
	rules: {
		"@antithrow/no-throwing-call": "error",
		"@antithrow/no-unsafe-unwrap": "error",
	},
}
