OXfmt Config

Opinionated, shared OXFmt configuration for my projects.

Install

bun add -D @mheob/oxfmt-config oxfmt

Usage

Create an oxfmt.config.ts at the root of your project and spread the provided config:

// oxfmt.config.ts
import { baseConfig } from '@mheob/oxfmt-config';
import { defineConfig } from 'oxfmt';

export default defineConfig({
	...baseConfig,
});

Add project-specific overrides on top:

// oxfmt.config.ts
import { baseConfig } from '@mheob/oxfmt-config';
import { defineConfig } from 'oxfmt';

export default defineConfig({
	...baseConfig,
	printWidth: 100,
});

Available configs
