How to obtain the uniapp applet plug-in after subcontracting

The UniApp applet supports plug-in subcontracting. After subcontracting, the plug-in can be independently released and updated. The steps to obtain the subcontracted plug-in include: referencing the subcontracted plug-in in the main package manifest.json; using the is attribute in the page to use the subcontracted plug-in; obtaining the subcontracted plug-in instance through getPluginManager().getPlugin(pluginId); the subcontracted plug-in is not When loading, you can pass in a callback function to obtain the instance asynchronously.

How to obtain the UniApp applet plug-in after subcontracting

The UniApp applet supports plug-in subcontracting. After subcontracting Plugins can be released and updated independently of the main package. To obtain the plug-in in the sub-package, you can follow the following steps:

1. Reference the sub-package plug-in in the main package

In the manifest of the main package Add a reference to the subpackaging plug-in in the .json file, for example:

{
  "usingComponents": {
    "my-plugin": "../packages/my-plugin/index"
  }
}

2. Use the subpackaging plug-in in the page

In the page, you can pass The is attribute in <template> uses a subcontracting plug-in, for example:

<template>
  <my-plugin is="plugin-from-subpackage"></my-plugin>
</template>

3. Get the subcontracting plug-in instance through the plug-in ID

If you need to get the subcontracted plug-in instance in JavaScript code, you can use the getPluginManager().getPlugin(pluginId) method, where pluginId is the subcontracted plug-in manifest.json The ID specified in the file, for example:

const pluginManager = getPluginManager();
const pluginInstance = pluginManager.getPlugin('plugin-from-subpackage');

4. Asynchronously obtain the subcontracting plug-in instance

If the subcontracting plug-in has not been loaded, getPlugin(pluginId) method will return null. At this point, you can pass in a callback function to be executed after the subpackaged plug-in is loaded:

pluginManager.getPlugin('plugin-from-subpackage', (pluginInstance) => {
  // 分包插件已加载完成
});

By following these steps, you can easily obtain the subpackaged plug-in in the UniApp applet.
