# node-window-polyfill
[](https://www.npmjs.com/package/node-window-polyfill)
Polyfill for the problem `window is not defined` in node.js.
It's inserting window object on globals
and inputing all needed sub-elements
with requiring web sockets dependency.
## Installation
Yarn
```
yarn add node-window-polyfill
```
Npm
```
npm install node-window-polyfill
```
### Requirements
Minimum ES5.
To use it in different environment it's required to clone and build it with the proper flag.
## Usage
Import it in global file, or in every file
where the source code requires the `window` object.
```typescript
import nodeWindowPolyfill from "node-window-polyfill";
nodeWindowPolyfill.register();
```
For shorter import that will call register directrly
```typescript
import "node-window-polyfill/register";
```
If you don't want to import 'ws' module and just create empty objects:
```typescript
import nodeWindowPolyfill from "node-window-polyfill";
nodeWindowPolyfill.register(false);
```
And the version previous ES versions:
```javascript
require('node-window-polyfill').register();
```
## What is polyfilled?
- usage of `window` in the code or libraries
- `window.setTimeout` - default `setTimeout` node function
- `window.clearTimeout` - default `clearTimeout` node function
- `window.WebSocket` - version from global object
- `window.ArrayBuffer` - version from global object only
- `window.addEventListener` - empty void function
- `window.navigator` - `{ onLine: true }`
- `window.isNodeJS` - to check if polyfills were aplied
- `window.localStorage` - in memory storage
- `window.Date` - version from global object
- `global.WebSocket` - using [ws](https://www.npmjs.com/package/ws) if the right flag is not set
- if the above functions/properties are already set in the `global` object then they will be taken into the account
## Configure
To configure development environment and run the tests,
first clone the repository:
```
git clone https://github.com/tgorka/node-window-polyfill.git
```
then (once you have `yarn` and node installed) install dependencies
```
yarn
```
## Build
To build the distribution and types
```
yarn build
```
The distribution is in the `dist` folder and types in the `types` folder.
To change defauld ES standard use `--target` flag. Ex.:
```
yarn build -target es3
```
## Test
After configuring we can run tests.
```
yarn test
```
We can use debug information logging with setting up env variable
```
DEBUG=nodeWindowPolyfill-* yarn test
```
