About the external.json File

The external.json file is created by developers. It stores component names and template paths in key-value pairs. The component name is used as the keyword, and the corresponding template path is used as the value.

Example

{
  "PluginProviderExample": "ets/pages/PluginProviderExample.js",
  "plugintemplate2": "ets/pages/plugintemplate2.js"
}
