It's that easy! ?

By the way,
If you like the plugin, star-ing this repo on GitHub really DOES boost my motivation to keep improving it ?

Available Options

Name Type Default Description
logUpdatedComponents Boolean false When true, log the updated components' names in the console with debug level.
isProduction Boolean false When true, disable the plugin.

In order to prevent random users from using the plugin on production sites, you're encouraged to pass a boolean value to the isProduction option. Recommended way of doing so is by passing process.env.NODE_ENV === 'production' to the plugin, and let module bundlers like webpack to transform the environment variable.

import FlashPlugin from 'vue-devtool-flash-updates'
Vue.use(FlashPlugin, {
  isProduction: process.env.NODE_ENV === 'production' // The plugin is disabled on production, enabled on other environments
