Common errors

error Error: Cannot find module 'timestamp-webpack-plugin' ↓

cause Package not installed or installed in wrong directory.

fix

Run 'npm install --save-dev timestamp-webpack-plugin' from project root.

error TypeError: TimestampWebpackPlugin is not a constructor ↓

cause Using ESM import incorrectly or wrong import syntax.

fix

Use 'const TimestampWebpackPlugin = require('timestamp-webpack-plugin');'

error Error: webpack.optimize.OccurrenceOrderPlugin is not a function ↓

cause This plugin may conflict with older Webpack 1/2 patterns.

fix

Warnings

deprecated Package is unmaintained since 2016. May not work with modern Webpack 4/5. ↓

fix Use a maintained alternative like webpack-manifest-plugin or webpack-subresource-integrity.

gotcha The 'path' option must be an absolute path; relative paths may not work correctly. ↓

fix Use path.resolve(__dirname, 'my-folder') or an absolute path.

gotcha Output format 'MM' has leading space, not zero-padded. Example: " 06" for June. ↓

fix Use 'MM' with leading zero if needed, or parse as integer.

Install

pnpm add timestamp-webpack-plugin

Imports

TimestampWebpackPlugin

wrong

import TimestampWebpackPlugin from 'timestamp-webpack-plugin';

correct

const TimestampWebpackPlugin = require('timestamp-webpack-plugin');

This package does not ship ESM; must use CommonJS require.

TimestampWebpackPlugin (ESM)

wrong

const { TimestampWebpackPlugin } = require('timestamp-webpack-plugin');

correct

import TimestampWebpackPlugin from 'timestamp-webpack-plugin';

If using ESM, default import works but named import does not.

Configuration

module.exports = { plugins: [new TimestampWebpackPlugin({ path: './', filename: 'build.json' })] };

Options include 'path' (absolute or relative) and 'filename'.

Quickstart

Shows basic Webpack configuration to output a timestamp.json file with build date and time.

const path = require('path');
const TimestampWebpackPlugin = require('timestamp-webpack-plugin');

module.exports = {
  entry: './src/index.js',
  output: { path: path.resolve(__dirname, 'dist'), filename: 'bundle.js' },
  plugins: [
    new TimestampWebpackPlugin({
      path: path.resolve(__dirname, 'dist'),
      filename: 'timestamp.json'
    })
  ]
};
