    vue-i18n

    vue-i18n

    Internationalization plugin for Vue.js

    You can introduce internationalization into your app with simple API. In addition to simple translation, support localization such as pluralization, number, datetime, etc. You can manage locale messages on single file component. Vue I18n is internationalization plugin of Vue.js. It easily integrates some localization features to your Vue.js Application. You can translate with pluralization. You must define the locale that have a pipe | separator, and define plurals in pipe separator. Such pluralization, however, does not apply to all languages (Slavic languages, for example, have different pluralization rules). In order to implement these rules you can pass an optional pluralizationRules object into VueI18n constructor options. If your current locale is not found in a pluralization map, the default rule of the english language will be used.

    vuex-persistedstate

    vuex-persistedstate

    Persist and rehydrate your Vuex state between page reloads

    Persist and rehydrate your Vuex state between page reloads. New plugin instances can be created in separate files, but must be imported and added to plugins object in the main Vuex file. It is possible to use vuex-persistedstate with Nuxt.js. It must be included as a NuxtJS plugin. Provides an array of any paths to partially persist the state. If no paths are given, the complete state is persisted. If an empty array is given, no state is persisted. Paths must be specified using dot notation. If using modules, include the module name. If it's not ideal to have the state of the Vuex store inside local storage, one can easily implement the functionality to use cookies for that (or any other you can think of). Any object following the Storage protocol (getItem, setItem, removeItem, etc) could be passed. If you need to use Local Storage (or you want to) but want to prevent attackers from easily inspecting the stored data, you can obfuscate it.

    webpack DevServer

    webpack DevServer

    Serves a webpack app and updates the browser on changes

    webpack-dev-server can be used to quickly develop an application. Options that are compatible with webpack-dev-middleware have a key icon next to them. This set of options is picked up by webpack-dev-server and can be used to change its behavior in various ways. When the server is started, there will be a message prior to the list of resolved modules. If you're using dev-server through the Node.js API, the options in devServer will be ignored. Pass the options as a second parameter instead: new WebpackDevServer(compiler, {...}). Be aware that when exporting multiple configurations only the devServer options for the first configuration will be taken into account and used for all the configurations in the array. HTML template is required to serve the bundle, usually it is an index.html file. Make sure that script references are added into HTML, webpack-dev-server doesn't inject them automatically.
