@aurelienbbn/oxfmt-config

One oxfmt config for every JS/TS repo: 100 columns, double quotes, trailing commas, multiline JSDoc, sorted package.json.

pnpm add -D @aurelienbbn/oxfmt-config oxfmt   # oxfmt >=0.67.0 <0.69.0 · Node ^22.19.0 || ^24.11.0

// oxfmt.config.ts
import { defineOxfmtConfig } from "@aurelienbbn/oxfmt-config";
import { defineConfig } from "oxfmt";

export default defineConfig(defineOxfmtConfig({ ignorePatterns: ["dist/**"] }));

Plain OxfmtConfig: works with oxfmt directly or as Vite+'s fmt config, no Vite+ dependency.

Exports

| Export | What | | ----------------------------------------- | -------------------------------------- | | defaultOxfmtConfig | the baseline object | | defineOxfmtConfig(overrides?, options?) | baseline + your overrides, fresh clone | | OxfmtConfig | type, re-exported from oxfmt |

| Setting | Value | | --------------------------- | ------------------------------------------- | | printWidth | 100 | | tabWidth | 2 | | semi | true | | singleQuote | false | | trailingComma | "all" | | arrowParens | "always" | | jsdoc.commentLineStrategy | "multiline" | | sortPackageJson | true | | ignorePatterns | .agents/**, **/*.wasm, pnpm-lock.yaml | | overrides | [] |

Lists merge, everything else replaces

defineOxfmtConfig(o)                         ignorePatterns, overrides  →  baseline + yours, deduplicated
defineOxfmtConfig(o, { replaceLists: true }) ignorePatterns, overrides  →  yours only (drops default ignores)
any other top-level key                                                  →  yours wins

Result is a structuredClone: mutating it never touches defaultOxfmtConfig.

Compatibility matrix: packed config vs baseline and current oxfmt, complete dependency-declaration checks, clean and badly formatted inputs.
