A collection of opinionated web-dev tooling configurations.

Quickstart

[!NOTE] The package manager that the CLI will use to install this package is dependent on what lockfile you have in the root of your project (i.e., having bun.lock will use bun, while having package-lock.json will use npm).

Currently, the only supported package managers are bun and npm.

This package contains a CLI that can be used to generate both eslint.config.ts and prettier.config.mjs files.

You can use it by running one of the following commands.

bunx @hiddenability/opinionated-defaults

npx @hiddenability/opinionated-defaults

• prettier-plugin-sort-imports

Manual Installation:

Alternatively, you can install it manually by running one of the following commands.

bun add @hiddenability/opinionated-defaults -d

npm i @hiddenability/opinionated-defaults -D

Usage:

Eslint:

// eslint.config.ts
import { eslintConfig, eslintConfigBase } from '@hiddenability/opinionated-defaults/eslint';
import eslintConfigPrettier from '@hiddenability/opinionated-defaults/eslint/prettier';

export default eslintConfig([...eslintConfigBase, ...eslintConfigPrettier]);

Prettier:

// prettier.config.mjs
import { prettierConfig, prettierConfigBase } from '@hiddenability/opinionated-defaults/prettier';

export default prettierConfig(prettierConfigBase);

Extending/Combining Prettier Configs:

Since Prettier uses a configuration object instead of a flat config like ESLint, to extend or combine configurations, the prettierConfig function will merge configs for you.

// prettier.config.mjs
import {
  prettierConfig,
  prettierConfig1,
  prettierConfig2,
} from '@hiddenability/opinionated-defaults/prettier';

export default prettierConfig(
  prettierConfig1,
  prettierConfig2,
  {/* your custom rules */},
  /*...*/
);

TailwindCSS Plugin:

When using prettier-config-tailwind, make sure to specify the CSS file that contains the @import "tailwindcss" directive.

For example, given the following css file:

/* /app/styles.css */
@import 'tailwindcss';

This should be a minimal version of your Prettier config:

// prettier.config.mjs
import {
  prettierConfig,
  prettierConfigBase,
  prettierConfigTailwind,
} from '@hiddenability/opinionated-defaults/prettier';

export default prettierConfig(prettierConfigBase, prettierConfigTailwind, {
  tailwindStylesheet: `./app/styles.css`,
});

TODO:

• Improve repository structure (How to manage configuration options within eslint dir?).
• Maybe convert into monorepo with one package per tool instead of multiple exports from one package.
• Prevent importing overlapping configurations (i.e., Next.js ESLint config contains base config).
• Support node module resolution.
• Maybe make declarative configurations instead of just providing wrapped config modules.
