Quickstart

Learn how to create a satellite, set up a collection, and save data from a Vue app.

1. Set up a satellite and new collection

Create a new satellite in the Juno's console.

After your project is ready, create a collection in your datastore, which we'll call demo, using the console.

2. Create a Vue app

Create a Vue app using the npm init command.

npm init vue@latest myjunoapp

3. Install the Juno SDK core library

Use @junobuild/core client library which provides a convenient interface for working with Juno from a Vue app.

Navigate to the Vue app and install @junobuild/core.

cd myjunoapp && npm i @junobuild/core

4. Insert data from your app

In App.vue, initialize the library with your public satellite ID.

Add an insert function to persist a document.

App.vue
<script setup>
import { initJuno, setDoc } from "@junobuild/core";
import { onMounted, ref } from "vue";

onMounted(
async () =>
await initJuno({
satelliteId: "wjar4-kiaaa-aaaal-ab4va-cai",
})
);

const doc = ref(undefined);

const insert = async () => {
doc.value = await setDoc({
collection: "demo",
doc: {
key: `my-key-${new Date().getTime()}`,
data: {
hello: "world",
},
},
});
};
</script>

<template>
<button @click="insert">Insert a document</button>
<span v-if="doc !== undefined">Key: {{ doc.key }}</span>
</template>

5. Start the app

Start the app, go to http://localhost:5173 in a browser, click "Insert a document," and you should see the data successfully persisted in your satellite on the blockchain.


Note-taking app

This tutorial, published as a blog post, demonstrates how to build a basic note-taking app. The app authenticates and identifies the user, stores their notes in a simple key-pair database, some files in storage, and allows the user to log in and retrieve their data. The app uses:

  • Juno datastore: a simple key-pair database for storing user data and other information.
  • Juno storage: a file storage system to store and serve user-generated content, such as photos.
  • Juno authentication: easy-to-use SDKs that support truly anonymous authentication.

Hosting

If you're looking to deploy your existing app or website developed with Vue and Juno, this guide is for you.

1. Set up a satellite

If you haven't created a satellite yet, go ahead and create a new one in the Juno's console.

2. Install Juno CLI and log in

Install the Juno command line interface by executing the following command in your terminal:

npm i -g @junobuild/cli

After the CLI is ready, log in to your satellite from your terminal to authenticate your device.

juno login

3. Deploy

Build your app:

npm run build

Deploy your project by running the following command from your project’s root folder:

juno deploy

When prompted to provide the name or path of the folder containing your built dapp files, answer dist.

4. Open

Open your browser and you should see your deployed app or website.

juno open
