Last verified Sep 9, 2026 against dedent@1.7.2.

dedent publishes both a CommonJS entry and a native ESM entry (ESM added in 1.3.0). require("dedent") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "dedent" works alongside it.

## What to do

1. Nothing to change. require("dedent") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import * as dedent from "dedent" works alongside it; use named imports for what the ESM entry exports.
2. TypeScript: types are bundled; install nothing extra.
