Use Juno with Vue

Explore how to create a Juno project developed with Vue.

Table of contents​

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
