| # Plugin Component | ||
|
|
||
| A wrapper that creates an iframe for a specified plugin and establishes a two-way communication channel with said plugin, allowing you to pass props (including callbacks between an app and a plugin). Note that the plugin must be built using the app-platform with entryPoints.plugin specified in the d2.config.js file. | ||
|
|
||
| ## Basic Usage (Defining a plugin within an app) | ||
|
|
||
| Within an app you can specify a plugin (either by providing its short name `pluginShortName`, or by specifying a URL directly (`pluginSource`). If you have provided `pluginSource`, this will take precedence (Note: lookup logic is TBD? Should we allow a URL only in development mode, for example?). | ||
|
|
||
| ```jsx | ||
| import { Plugin } from '@dhis2/app-runtime' | ||
|
|
||
| // within the app | ||
| const MyApp = () => ( | ||
| <Plugin | ||
| pluginShortName={mutation} | ||
| onError={(err) => { | ||
| console.error(err) | ||
| }} | ||
| showAlertsInPlugin={true} | ||
| numberToPass={'42'} | ||
| callbackToPass={({ name }) => { | ||
| console.log(`Hi ${name}!`) | ||
| }} | ||
| /> | ||
| ) | ||
| ``` | ||
|
|
||
| ## Basic Usage (Using properties from the parent app) | ||
|
|
||
| You must build your plugin with the app-platform. If you have done this, your entry component will be passed the props from the parent app. From the example above, the properties `numberToPass` and `callbackToPass` will be available in the build plugin (when it is rendered with a <Plugin> component). | ||
|
|
||
| ```jsx | ||
| // your plugin entry point (the plugin itself) | ||
|
|
||
| const MyPlugin = (propsFromParent) => { | ||
| const { numberToPass, callbackToPass: sayHi } = propsFromParent | ||
| return ( | ||
| <> | ||
| <p>{`The meaning of life is: ${numberToPass}`}</p> | ||
| <button onClick={() => sayHi({ name: 'Arthur Dent' })}> | ||
| Say hi | ||
| </button> | ||
| </> | ||
| ) | ||
| } | ||
| ``` | ||
|
|
||
| ## Plugin Props (reserved props) | ||
|
|
||
| | Name | Type | Required | Description | | ||
| | :--------------------: | :------------: | :---------------------------------------------: | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | ||
| | **pluginShortName** | _string_ | _required_ if `pluginSource` is not provided | The shortName of the app/plugin you wish to load (matching the result from api/apps). Used to look up the plugin entry point. If this is not provided, `pluginSource` must be provided. `pluginSource` will take precedence if provided. | | ||
| | **pluginSource** | _string_ (url) | _required_ if `pluginShortName` is not provided | The URL of the plugin. If this is not provided, `pluginShortName` must be provided. | | ||
| | **onError** | _Function_ | _optional_ | Callback function to be called when an error in the plugin triggers an error boundary. You can use this to pass an error back up to the app and create a custom handling/UX if errors occur in the plugin. In general, it is recommended that you use the plugin's built-in error boundaries | | ||
| | **showAlertsInPlugin** | _boolean_ | _optional_ | If `true`, any alerts within the plugin (defined with the `useAlert` hook) will be rendered within the iframe. By default, this is `false`. It is recommended, in general, that you do not override this and allow alerts to be hoisted up to the app level | | ||
|
|
||
| ## Plugin Props (custom props) | ||
|
|
||
| You can specify pass any other props on the <Plugin> component and these will be passed down to the plugin (provided it was built with app-platform). When props are updated, they will be passed back down to the plugin. This mimics the behaviour of a normal React component, and hence you should provide stable references as needed to prevent rerendering. | ||
|
|
||
| ## Extended example | ||
|
|
||
| See these links for an extended example of how <Plugin> component can be used within an [app](https://github.com/tomzemp/workingplugin/blob/plugin-wrapper-in-platform/src/App.js) and consumed within the [plugin](https://github.com/tomzemp/workingplugin/blob/plugin-wrapper-in-platform/src/Plugin.js). |
