create-editorconfig

Generate an .editorconfig for any project. Interactive prompts, ready-made presets, or a single -y for sensible defaults.

npx create-editorconfig

Install

Nothing to install — just run npx create-editorconfig from the directory where you want the file. Requires Node.js >=18.3.0.

Quick start

# interactive prompts
npx create-editorconfig

# accept defaults, no prompts
npx create-editorconfig -y

# detect the ecosystem and pick a matching preset
npx create-editorconfig --detect

# emit a Python project preset
npx create-editorconfig --preset python

# write to a specific directory
npx create-editorconfig -y ./packages/foo

# append a new section to an existing file
npx create-editorconfig --merge --preset js

Presets

--preset <name> skips the prompts and emits a ready-made multi-section config:

| Preset | What you get | | --------- | ----------------------------------------------------------------------------------------------------------- | | default | Same as -y. Single [*] section with safe defaults. | | js | Defaults + explicit JS/TS/JSON/YAML sections, [*.md] keeping trailing whitespace, [Makefile] with tabs. | | python | 4-space indent + [Makefile] tab override. | | go | [*.go] and [Makefile] set to tabs, default elsewhere. |

--detect picks one of these automatically by sniffing the target directory: go.mod or *.go → go, pyproject.toml / requirements.txt / *.py → python, package.json / tsconfig.json / *.ts/*.tsx/*.js → js, otherwise default.

Flags

| Flag | Description | | --------------------- | ---------------------------------------------------------------------------- | | -y, --yes | Generate the default config without prompting. | | -p, --preset <name> | Generate from a named preset (default, js, python, go). | | --detect | Pick a preset by sniffing the target directory. | | -f, --force | Overwrite an existing file. | | -m, --merge | Append new sections to an existing .editorconfig instead of erroring out. | | -o, --output <path> | Write to a specific path. | | --stdout | Print to stdout instead of writing to disk. |

A positional argument sets the target directory: npx create-editorconfig -y ./packages/foo.

Supported properties

Every property in the EditorConfig specification is supported, plus the de-facto max_line_length:

• root (preamble)
• charset — latin1, utf-8, utf-8-bom, utf-16be, utf-16le
• end_of_line — cr, crlf, lf
• indent_style — space, tab
• indent_size — positive integer, or tab
• tab_width
• insert_final_newline
• trim_trailing_whitespace
• max_line_length

Every property accepts unset in per-glob override sections to remove a parent rule.
