# Vue.js HelloWorld

This tutorial shows you how to use the SDK in your Vue.js application.\
You will replace the content of the default `HelloWorld` component and display the current block height of the æternity testnet.

## 1. Install Vue.js

```bash
npm install -g @vue/cli
```

## 2. Create a new Vue.js project

```bash
vue create my-project
```

## 3. Switch to the folder of your Vue.js project

```bash
cd my-project
```

## 4. Install the SDK

```bash
npm install @aeternity/aepp-sdk
```

## 5. Modify the HelloWorld component

```js
<!-- src/components/HelloWorld.vue -->

<script>
import { AeSdk, Node } from '@aeternity/aepp-sdk'

export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: 'Loading latest block ...'
    }
  },
  async mounted () {
    // Init required Node class
    const node = new Node('https://testnet.aeternity.io')

    // Init SDK instance with AeSdk class
    const aeSdk = new AeSdk({
       nodes: [{ name: 'test-net', instance: node }],
    })
    // Start using the SDK
    const height = await aeSdk.getHeight()
    this.msg = 'Current Block: ' + height
  }
}
</script>
```

## 6. Run the application

```bash
npm run serve
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.aeternity.com/developer-documentation/aepp-sdk-js/docs/tutorials/vuejs/helloworld-blockheight.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
