Installation (Vue)

Check our Vue example application

To install Tolgee Vue integration library run:

npm install @tolgee/vue

First initialize Tolgee and use VueTolgee.

import { Tolgee, DevTools, VueTolgee, FormatSimple } from '@tolgee/vue';

const tolgee = Tolgee()
language: 'en',

// for development
apiUrl: import.meta.env.VITE_APP_TOLGEE_API_URL,
apiKey: import.meta.env.VITE_APP_TOLGEE_API_KEY,

// for production
staticData: {


app.use(VueTolgee, { tolgee });

Check all tolgee options and tolgee plugins.

VueTolgee plugin makes $t function globally available.

Wrap your application with TolgeeProvider component. TolgeeProvider will start tolgee at correct moment and waits for initial data to be loaded. You can provide fallback slot, to show custom loader while translations are being loaded.

<template v-slot:fallback>
<App />

If you bootstrapped your application with vue-cli, your .env.development.local file should look like this:


Otherwise, you can set the properties directly, or you can use plugins like dotenv-webpack plugin.

Obtaining Tolgee API key is described in Integration chapter.

Preparing for production

Tolgee will automatically omit DevTools from your bundle when you build your app for production. So it won't fetch translations directly from Tolgee Platform and it won't allow users to modify translations.

There are generally two ways how to use translations in production:

In production mode, you should never use localization data directly from Tolgee REST API, because it can negatively affect your page performance.
