namespace-bundler

1.0.7 verified Sat Apr 25 auth: no javascript abandoned

A JavaScript bundler (v1.0.7, last updated 2017) that concatenates files following namespace patterns without requiring import/require statements. Designed for legacy browser support including IE8, it produces readable output in dev tools. Simple API with bundle() returning content and writeToFile() for synchronous output. No active development since 2017.

Common errors

error Error: Cannot find module 'namespace-bundler' ↓

cause Package not installed.

fix

npm install --save-dev namespace-bundler

error TypeError: Bundler.bundle is not a function ↓

cause Wrong import style (ESM import used).

fix

Use const Bundler = require('namespace-bundler');

error Cannot read property 'value' of undefined ↓

cause bundle() called with invalid path or empty directory.

fix

Ensure the path is absolute and contains JavaScript files.

Warnings

gotcha No import/require in source files: the bundler relies on namespace pattern ordering. ↓

fix Ensure files use namespace pattern (e.g., window.MyApp = window.MyApp || {};) for dependency order.

gotcha writeToFile is synchronous; may block event loop for large projects. ↓

fix Use value property and write asynchronously with fs.writeFile if needed.

deprecated No updates since 2017; consider modern bundlers like webpack or esbuild. ↓

fix Migrate to an actively maintained bundler.

Install

npm install namespace-bundler

yarn add namespace-bundler

pnpm add namespace-bundler

Imports

default

wrong

import Bundler from 'namespace-bundler'

correct

const Bundler = require('namespace-bundler')

Package uses CommonJS; no ESM exports.

bundle

wrong

const { bundle } = require('namespace-bundler')

correct

const Bundler = require('namespace-bundler'); Bundler.bundle('/path')

bundle is a method on the default export, not a named export.

value

wrong

const { value } = require('namespace-bundler').bundle('/path')

correct

const result = require('namespace-bundler').bundle('/path'); result.value

value is a property of the returned object, not a direct export.

Quickstart

Shows basic usage: bundle a directory and get content or write to file.

const Bundler = require('namespace-bundler');
const result = Bundler.bundle('/path/to/src');
console.log(result.value);
result.writeToFile('/path/to/output.js');
