eslint-config-decent


A decent ESLint configuration for TypeScript projects.

Example usage

``mjs
// eslint.config.mjs

import { config } from 'eslint-config-decent';

export default config({
tsconfigRootDir: import.meta.dirname,
});
`

Override parserOptions

`mjs
// eslint.config.mjs

import { config } from 'eslint-config-decent';

export default config({
parserOptions: {
projectService: {
defaultProject: 'tsconfig.json',
},
tsconfigRootDir: import.meta.dirname,
},
});
`

Disable require-extensions rules

`mjs
// eslint.config.mjs

import { config } from 'eslint-config-decent';

export default config({
enableRequireExtensions: false,
tsconfigRootDir: import.meta.dirname,
});
`

Override a rule

`mjs
// eslint.config.mjs

import { config } from 'eslint-config-decent';

export default [
...config({
tsconfigRootDir: import.meta.dirname,
}),
{
files: ['*/.ts'],
rules: {
'@typescript-eslint/no-confusing-void-expression': 'off',
},
},
];
`

Agent Skill for AI-Assisted Development

This package includes an Agent Skill that teaches AI coding assistants (Claude Code, OpenCode, etc.) to follow the same TypeScript standards enforced by the ESLint rules.

$3

`bash
npx skills add jgeurts/eslint-config-decent
`

Or copy manually:

`bash
mkdir -p .claude/skills
cp -r node_modules/eslint-config-decent/enforcing-typescript-standards .claude/skills/
`

> Note: The skill is copied to your project and won't update automatically. Re-run the install command after updating eslint-config-decent to get the latest skill instructions.

Once installed, AI assistants will automatically apply the project's TypeScript standards when creating or modifying .ts and .tsx files. The skill instructs the AI to:

- Write code with explicit return types and member accessibility
- Organize imports correctly (order, extensions, type-only imports)
- Follow class member ordering conventions
- Avoid anti-patterns like useless comments, nested ternaries, and await in loops
- Run npm run lint:code to verify compliance before completing tasks

To override or extend the default instructions, edit the SKILL.md` file in your project's skills directory:
