rollup-simple-configer

0.1.3 verified Mon Apr 27 auth: no javascript

A utility to quickly generate Rollup configurations for TypeScript projects. Version 0.1.3, stable but infrequent releases. Simplifies setup with minimal boilerplate, handling TypeScript compilation, CommonJS/ESM output, and external dependencies. Different from manual configs by offering a declarative API with sensible defaults, reducing the learning curve for bundling TypeScript with Rollup. Currently without active maintenance updates.

Common errors

error Error [ERR_REQUIRE_ESM]: require() of ES Module /path/to/rollup-simple-configer/index.mjs not supported. ↓

cause Package is ESM-only, but importing via require() in CommonJS project.

fix

Use dynamic import() or refactor project to use ESM.

error TypeError: Plugin is not a function ↓

cause Passing a plugin constructor instead of an instance in plugins array.

fix

Ensure plugins are instantiated (e.g., typescript() instead of typescript).

Warnings

breaking Package is ESM-only; importing via require() or using CJS projects will fail. ↓

fix Use dynamic import() or switch project to ESM.

deprecated All options are considered stable, but no active development is expected. Consider manual Rollup config for complex needs. ↓

fix Evaluate if custom config is needed.

gotcha The `plugins` option must include an array of Rollup plugins; it does not preset TypeScript plugin automatically. ↓

fix Always pass the desired plugins in the options.

gotcha The package does not handle TypeScript config resolution; tsconfig must be handled separately via plugin options. ↓

fix Configure TypeScript plugin explicitly with tsconfig path.

Install

npm install rollup-simple-configer

pnpm add rollup-simple-configer

Imports

createConfig

wrong

const { createConfig } = require('rollup-simple-configer')

correct

import { createConfig } from 'rollup-simple-configer'

Package is ESM-only since v0.1.0

default

wrong

const createConfig = require('rollup-simple-configer')

correct

import createConfig from 'rollup-simple-configer'

Default export available, but prefer named import for clarity

ConfigOptions
```
import type { ConfigOptions } from 'rollup-simple-configer'
```
TypeScript type, not a runtime value, only for type annotations

Quickstart

Creates a Rollup configuration for a TypeScript project with CJS and ESM outputs, using @rollup/plugin-typescript.

import { createConfig } from 'rollup-simple-configer';
import typescript from '@rollup/plugin-typescript';

const config = createConfig({
  input: 'src/index.ts',
  output: [
    { file: 'dist/bundle.cjs.js', format: 'cjs' },
    { file: 'dist/bundle.esm.js', format: 'esm' }
  ],
  plugins: [typescript()],
  external: ['lodash']
});

export default config;
