esbuild-plugin-remove-duplicate-require

0.0.0 verified Fri May 01 auth: no javascript

ESBuild plugin that removes duplicate require statements from minified builds, reducing bundle size. Version 0.0.0 is the initial release. It works by detecting and deduplicating repeated require() calls in the output, which can occur when multiple modules import the same dependency. Different from many plugins, it focuses specifically on the final bundle output rather than during tree-shaking. Ships TypeScript types.

Common errors

error Error: Cannot find module 'esbuild-plugin-remove-duplicate-require' ↓

cause Wrong package name used.

fix

npm install esbuild-plugin-rdi

error TypeError: rdiPlugin is not a function ↓

cause Default import used instead of named import.

fix

import { rdiPlugin } from 'esbuild-plugin-rdi'

Warnings

gotcha Plugin modifies the final bundle after minification; ensure it runs after other plugins that might introduce duplicates. ↓

fix Place rdiPlugin last in the plugins array.

deprecated The package name in npm is 'esbuild-plugin-rdi' not 'esbuild-plugin-remove-multiple-require'. ↓

fix Install as 'esbuild-plugin-rdi'. Import from 'esbuild-plugin-rdi'.

Install

npm install esbuild-plugin-remove-multiple-require

yarn add esbuild-plugin-remove-multiple-require

pnpm add esbuild-plugin-remove-multiple-require

Imports

rdiPlugin

wrong

import rdiPlugin from 'esbuild-plugin-rdi'

correct

import { rdiPlugin } from 'esbuild-plugin-rdi'

ESM default export not available; must use named import.

rdiPlugin

wrong

const rdiPlugin = require('esbuild-plugin-rdi')

correct

const { rdiPlugin } = require('esbuild-plugin-rdi')

CommonJS: destructure the required object to get the named export.

type imports
wrong
```
import { RdiOptions } from 'esbuild-plugin-rdi'
```
correct
```
import type { RdiOptions } from 'esbuild-plugin-rdi'
```
TypeScript only: plugin options type may be available as named export; use type import for runtime elimination.

Quickstart

Uses rdiPlugin in an esbuild build to remove duplicate require statements from the bundled output.

import { rdiPlugin } from 'esbuild-plugin-rdi';
import * as esbuild from 'esbuild';

await esbuild.build({
  entryPoints: ['app.ts'],
  bundle: true,
  outfile: 'out.js',
  plugins: [rdiPlugin()],
});
