tn-prettier-imports

A Prettier v3 plugin that keeps import and export statements on a single line, overriding Prettier's default of wrapping long specifier lists one-per-line.

Install

Requires prettier@^3.

Usage

Add it to the plugins array of your Prettier config:

Works for JavaScript and TypeScript — .js, .jsx, .ts, .tsx (babel, babel-ts and typescript parsers).

What it collapses

| Statement | Behavior |

| import { ... } from '...' | → single line | | import Default, { ... } from '…' | → single line | | import type { ... } from '...' | → single line | | import * as ns from '...' | → single line | | export { ... } (local) | → single line | | export { ... } from '...' | → single line | | export type { ... } from '...' | → single line | | export * from '...' | → single line |

Everything else is formatted exactly as vanilla Prettier would — object literals, export const/function/class declarations and export default are left untouched.

Comment safety

A statement that contains a line comment inside its braces is left in Prettier's multi-line layout, because collapsing it would let the // swallow the rest of the line:

Block comments (/* ... */) collapse inline and are preserved.

How it works

The plugin wraps Prettier's built-in estree printer. For each import / export statement it takes the Doc that the stock printer produced and rewrites it into its flat, single-line form; every other node is returned unchanged. See CLAUDE.md for the architecture.
