A resume that you created on a **Vue.js Resume Builder**, a Vue.js Resume Builder that **YOU** created! Now **THAT’s** the good stuff. That’s that stuff that distinguishes **YOU** from the flock of **“Word” and “PDF”**.

### 5 Reason for Creating your Resume Builder in Vue

1. Vue.js is very **performant**: It works with a virtual DOM, a lightweight representation of the actual DOM. It allows Vue to optimize updates and significantly improves performance.

2. With its component-based development, Vue helps **structure code**, which makes maintaining it easier.

3. Vue.js simplifies the **rendering of content** immensely: When your data changes, the connected part of the DOM automatically re-renders.

4. Vue is a **progressive framework**: That means you can introduce Vue into an existing project. You don't have to rewrite everything, instead, you can only use Vue for a specific page or section of your project.

5. It is **open-source**, and you can be sure that it will be continued due to its popularity.

### Overcoming Challenges in Vue and Developing a Resume Builder

If you are already familar with CSS, HTML, and JavaScript, with the gentlest learning curve, Vue is your doorway into a fully-fledged front-end or even a full-stack web developer.

Mastering Vue can present a learning curve for absolute beginners unfamiliar with CSS, HTML, and JavaSrcript, this is due to its extensive features and concepts like data properties, methods, computed properties, custom events, and lifecycle hooks. While Vue offers excellent [documentation](https://vuejs.org/guide/introduction.html), it can be challenging for developers to get a deeper understanding without a structured learning path.

The best way to familarize yourself with a new framework is to work on a portfolio project, and this course is exactly that. You won't find anything about creating a portfolio project in any offical documentation. This course also provides a **structured learning path**, breaking down complex concepts into manageable lessons.

Our aim is to ensure that you progressively build your understanding of Vue, starting from the basics and advancing to more complex topics. And thus, this course is tailored for Vue.js beginners, leveraging the Options API in Vue 3 for its **beginner-friendly** approach.

We emphasize practical application as the most effective way to become familiar with the material, ensuring you apply newly introduced concepts from the course's very first lesson. Instead of practicing on simple to-do list apps, you have the opportunity to create a substantial portfolio project that you can showcase to friends, potential employers, and even use for yourself to create a Developer Resume.

## Editing the resume content

We have seen how to render data from the data object in the previous lesson. Now, we enable the user to change this data. We will learn two more directives in Vue: `v-model` and `v-on`.

The code editor contains the final code from the previous lesson. Feel free to use it as a starting point to dive into this lesson.

<ReplitEmbed src="https://replit.com/@newlineauthors/module-3-lesson-1" />

Vue provides a very useful directive, `v-model`, with which we can display as well as edit input data.

```html
<input v-model="name">
```

:::note

`v-model` sets the value attribute of an input element to the value it is tied to. At the same time, if the user inputs something, this would overwrite the default value in the data object. This is often referred to as two-way data binding.

:::

Without the v-model directive, we would do the data binding and the updating in two steps.

With `v-bind`, we can retrieve the value from the data property and display it.

```html
<input :value="name">
```

But we also want our input to get registered and update the state. For that, we would need an event listener that listens to the input event.
It should then update the value according to the input.

The way to add event listeners in Vue is with the `v-on` directive. You write `v-on:`, and then the event you want to listen to.
The value of this directive is the event handler.

```html
<input :value="name" v-on:input="myEventHandler">
```

When the user types or makes changes to the input's value, the "myEventHandler" method in your Vue component will be called. You can use this to capture the user's input, process it, and perform actions based on the changes in the input field.

Remember how the `v-bind` directive can be abbreviated with just a colon?
The `v-on` directive can be abbreviated with an `@` sign.

```html
<input :value="name" @input="myEventHandler">
```

Just like in Vanilla JavaScript, we can write the event listener inline if we want to. To update the value of the name property on input, we can use the following event handler:

```html
<input :value="name" @input="event => name = event.target.value">
```

The `v-model` directive is pretty neat and makes our life a lot simpler. It can be used on `input`, `textarea`, and `select` elements. So, one approach would be to convert all of our text into input elements and take advantage of the ease of the `v-model` directive.

Let’s test this out by converting the first headline into an input element.

```html
<input type="text" v-model="headlines[0]">
```

Of course, we would have to change the styling of the input element for this to make it look like a headline again. For this, we could remove the background and the border. What we cannot fix is that an input element is only one line long. It cannot break and continue in the next line.

It is best to keep the non-input elements, so `h4` in the case of the headlines, and add `contenteditable="true"` to it. We cannot use `v-model` on these non-input elements, but we can get the same functionality with v-bind and an event listener.

Let's add `contenteditable="true"` to the heading and see what happens. A box renders around the text when we click on it. We can edit the text in the box, and if we hit enter, we see that the box would also span across lines. If we lose the focus, our input remains visible. The data object still needs to be updated.

I will show you what I mean. Let's print out the current value of headline one.

```html
<div>current value of headline one: {{ headlines[0] }}</div>
```

You see, it does not get updated automatically. If we use an input element with `v-model`, it does update.

```html
<h4 class="section-headline" contenteditable="true">{{headlines[0]}}</h4>
<input v-model="headlines[0]">
```

That is because the `v-model` directive updates the data object. To achieve this functionality for our non-input elements, we need to add an event listener that updates the data property of the data object. As a reference point, this code is equivalent to `v-model`.

```html
<input :value="headlines[0]" @input="event => headlines[0] = event.target.value">
```

For a `non-input` element, the difference is that the text is not the `value` of the element but the `innerText`. Therefore, we need to access it with `event.target.innerText` instead of with `event.target.value`.

```html
<h4
  class="section-headline"
  contenteditable="true"
  @input="event => headlines[0] = event.target.innerText">
  {{ headlines[0] }}
</h4>
```

:::warning
If you are using a different browser than Chrome the `input` event might not work as expected. That is because some browsers move the cursor to the beginning of the element after each character is typed, which can disrupt the typing experience.

To prevent this, you can use the `blur` event instead.

For example: `@blur="event => headlines[0] = event.target.innerText"`

This way the event fires once the element you are editing loses focus, which means that the data you type gets saved once you click somewhere else.
To follow along from a browser other than Chrome, use `@blur` instead of `@input` in this course whenever we make text editable.
