# Window
The vast majority of plugins should be developed using this method. It provides a browser window where you can develop the desired features, and this window will automatically pop up when the user clicks on the plugin.
We can set the window properties by setting the main field in the manifest.json file.
{% code lineNumbers="true" %}
```json
{
"main": {}
}
```
{% endcode %}
Set the default open link URL for the window:
```json
{
"main": {
"url": "index.html"
}
}
```
Set the default width and height of the window:
```json
{
"main": {
"url": "index.html",
"width": 640,
"height": 480
}
}
```
After setting other metadata.json fields, the final code is as follows:
{% tabs %}
{% tab title="manifest.json" %}
```json
{
"id": "LBCZE8V6LPCKD",
"version": "1.0.0",
"name": "Window Plugin",
"logo": "/logo.png",
"keywords": [],
"main":
{
"url": "index.html",
"width": 640,
"height": 480
}
}
```
{% endtab %}
{% tab title="index.html" %}
```html
```
{% endtab %}
{% tab title="plugin.js" %}
```javascript
eagle.onPluginCreate((plugin) => {
console.log('eagle.onPluginCreate');
console.log(plugin);
document.querySelector('#message').innerHTML = `
id: ${plugin.manifest.id}
version: ${plugin.manifest.version}
name: ${plugin.manifest.name}
logo: ${plugin.manifest.logo}
path: ${plugin.path}
`;
});
eagle.onPluginShow(() => {
console.log('eagle.onPluginShow');
});
eagle.onPluginHide(() => {
console.log('eagle.onPluginHide');
});
eagle.onPluginBeforeExit((event) => {
console.log('eagle.onPluginBeforeExit');
});
```
{% endtab %}
{% endtabs %}
