Pseudo-fork of react-new-window by Rubens Mariuzzo

Features

• Small footprint
• Support the full window.open api.
• Built for React 16 and 17 (uses ReactDOM.createPortal).
• Handler for blocked popups (via onBlock prop).
• Handler for created popups (via onOpen prop)
• Center popups according to the parent window or screen.
• No external dependencies Only React 16 or 17 as a peer dependency.

What's different from react-new-window?

• Codebase has been rewritten in TypeScript with many bugs discovered and fixed in the process.
• Codebase uses React hooks making react-new-improved-window functionally declarative.
• closeWithParent property indicating to close the new window when the parent window closes.
• Installation doesn't require the --force switch since both React 16 and 17 are supported.
• If the title property is missing the new window will use the parent window's title.
• The features property no longer require height and width if not given and the center property is set then this will default to height: 600, width: 640.
• Note: Internet Explorer will no longer be supported.

Installation

npm i react-new-improved-window --save

Usage

import React from 'react'
import NewImprovedWindow from 'react-new-improved-window'

const Demo = () => (
  <Index>
    <h1>Hi 👋</h1>
  </Index>
)

When <Index /> is mounted a popup window will be opened. When unmounted then the popup will be closed.

The children contents is what will be rendered into the new popup window. In that case Hi 👋 will be the content. The content can include any react-stateful code.

Development

To start contributing to this project, please do:

1. Fork and clone this repo.
2. Make the changes you want to.
3. Create and push a PR.

To build the library you should have TypeScript installed globally npm install -g typescript

npm run build

Test (example)

In the base directory:

cd example
npm install # You only need to do this once
npm start

This will start the example React App. The example app is linked directly to react-new-improved-window and will pick up any changes made when the library is built.

See: example/src/App.tsx
