Juno Vite Plugin

A Vite plugin for Juno.

Getting started

The plugin automatically loads your Satellite and Orbiter IDs.

With these values, you can instantiate Juno in your code without the need to manually define environment variables.

await Promise.all([initSatellite(), initOrbiter()]);

Environment variables

Those following environment variables are injected by this plugin:

Environment variable	Value in mode development	Value for other modes
VITE_SATELLITE_ID	jx5yt-yyaaa-aaaal-abzbq-cai	The Satellite ID for the mode from your Juno configuration file.
VITE_ORBITER_ID	undefined	The Orbiter ID from your Juno configuration file.
VITE_INTERNET_IDENTITY_ID	rdmx6-jaaaa-aaaaa-aaadq-cai	rdmx6-jaaaa-aaaaa-aaadq-cai
VITE_ICP_LEDGER_ID	ryjl3-tyaaa-aaaaa-aaaba-cai	ryjl3-tyaaa-aaaaa-aaaba-cai
VITE_ICP_INDEX_ID	qhbym-qaaaa-aaaaa-aaafq-cai	qhbym-qaaaa-aaaaa-aaafq-cai
VITE_NNS_GOVERNANCE_ID	rrkah-fqaaa-aaaaa-aaaaq-cai	rrkah-fqaaa-aaaaa-aaaaq-cai
VITE_CMC_ID	rkp4c-7iaaa-aaaaa-aaaca-cai	rkp4c-7iaaa-aaaaa-aaaca-cai

VITE_ is the default prefix used by Vite. It can be customized as described in Vite's documentation.

Installation

npm i @junobuild/vite-plugin -D

Usage

// vite.config.js
import juno from '@junobuild/vite-plugin';

export default defineConfig({
  plugins: [juno()]
});

Options

The plugin can be customized using the optional juno configuration object. This allows you to control how the Juno Docker container is used in your project, especially during local development or end-to-end (E2E) testing.

juno.container

Use the container option to enable, disable, or fine-tune the use of Juno Docker.

You can provide:

• false — to disable the container entirely.
• true — to enable the container with default settings (only in development mode), which is also the default behavior.
• An object with the following fields:
  • url (string, optional): A custom container URL, including the port. Example: http://127.0.0.1:8000
  • modes (string[], optional): An array of modes (e.g., ['development', 'test']) during which the container should be used.

By default, the container is mounted only in development mode.

// vite.config.js
import juno from '@junobuild/vite-plugin';

export default defineConfig({
  plugins: [
    juno({
      container: {
        url: 'http://127.0.0.1:8000',
        modes: ['development', 'test']
      }
    })
  ]
});
