Installation

Install

npm install tersify

pnpm add tersify

yarn add tersify

tersify ships as both ESM and CommonJS, with type declarations for each, so either module system works without a shim.

Import

import { tersify } from 'tersify'

const { tersify } = require('tersify')

Node and the browser

The package publishes a browser field that swaps two modules at bundle time:

Module	Node build	Browser build
constants	constants.ts	constants.browser.ts
tersifyFunction	tersifyFunction.ts	tersifyFunction.browser.ts

The Node build parses function source with acorn to produce the most compact representation it can. The browser build drops acorn entirely and falls back to string-based formatting, which keeps the bundle small. Any bundler that honours the browser field — Vite, webpack, esbuild, Rollup with @rollup/plugin-node-resolve — picks the right one for you.

Function output can therefore differ slightly between the two builds. Everything else — objects, arrays, primitives, class instances, options — behaves identically.
