# Plugins
The app will load all plugins from the source checkout in the dev mode, from the user's plugins directory at all times (click `Open Plugins Directory` under `Settings` > `Plugins`) and from the directory specified by the `TABBY_PLUGINS` environment var.
Only modules whose `package.json` file contains a `tabby-plugin` keyword will be loaded.
If you're currently in your plugin's directory, start Tabby as `TABBY_PLUGINS=$(pwd) tabby --debug`
A plugin should only provide a default export, which should be a `NgModule` class (or a `NgModuleWithDependencies` where applicable). This module will be injected as a dependency to the app's root module.
```javascript
import { NgModule } from '@angular/core'
@NgModule()
export default class MyModule {
constructor () {
console.log('Angular engaged, cap\'n.')
}
}
```
Plugins provide functionality by exporting singular or multi providers:
```javascript
import { NgModule, Injectable } from '@angular/core'
import { ToolbarButtonProvider, ToolbarButton } from 'tabby-core'
@Injectable()
export class MyButtonProvider extends ToolbarButtonProvider {
provide (): ToolbarButton[] {
return [{
icon: 'star',
title: 'Foobar',
weight: 10,
click: () => {
alert('Woohoo!')
}
}]
}
}
@NgModule({
providers: [
{ provide: ToolbarButtonProvider, useClass: MyButtonProvider, multi: true },
],
})
export default class MyModule { }
```
See `tabby-core/src/api.ts`, `tabby-settings/src/api.ts`, `tabby-local/src/api.ts` and `tabby-terminal/src/api.ts` for the available extension points.
Also check out [the example plugin](https://github.com/Eugeny/tabby-clippy).
Publish your plugin on NPM with a `tabby-plugin` keyword to make it appear in the Plugin Manager.
