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.

 component. The ImgUpload component needs an input field of the type file. We explicitly state which file types we accept. In this case, we want to accept all the common image file types. Some browsers use this information to filter the file selection dialog so the user sees only files with the specified extensions.

<template>
    <label>
        Upload Image
        <input
            type="file"
            accept="image/jpeg, image/png, image/jpg"
        >
    </label>
</template>

In order for us to change the photo, we need to add an event listener to the input element. I will call the event handler 

<template>
    <label>
        Upload Image
        <input type="file"
            accept="image/jpeg, image/png, image/jpg"
            @change="changeImage">
    </label>
</template>

Let’s add the event handler method. The handler takes in the event argument and extracts the selected file from it. The

We are able to upload our image now, but what if we don’t want an image at all?
Personal information is expected in a resume depending on the country, and in some countries, applicants apply without a picture.

Therefore, we will add a configuration option with which the user can choose to display or hide the picture.

## Configuring the photo

### Uploading an image

For that, we will create an `ImgUpload` component. The ImgUpload component needs an input field of the type file. We explicitly state which file types we accept. In this case, we want to accept all the common image file types. Some browsers use this information to filter the file selection dialog so the user sees only files with the specified extensions.

```html
<template>
    <label>
        Upload Image
        <input
            type="file"
            accept="image/jpeg, image/png, image/jpg"
        >
    </label>
</template>
```

In order for us to change the photo, we need to add an event listener to the input element. I will call the event handler `changeImage`.

```html
<template>
    <label>
        Upload Image
        <input type="file"
            accept="image/jpeg, image/png, image/jpg"
            @change="changeImage">
    </label>
</template>
```

Let’s add the event handler method. The handler takes in the event argument and extracts the selected file from it. The `files` attribute will contain a `FileList` object. If a file was selected, we can access that file with an index of `0`. If no file is selected, the event will still fire, and the `FileList` object will be empty. Therefore, we need to check if our `selectedFile` contains a value. If so, we create an instance of the `FileReader`. The `FileReader` is a built-in JavaScript object that allows us to read the contents of files.

With `reader.readAsDataURL(selectedFile)`, we initiate the process of reading the selected file, and when this is complete, the `load` event fires. In order to react to this event, we register an event listener. We add that listener above the `reader.readAsDataURL(selectedFile)` call to make sure that it is available when the `load` event fires.

Once the file is loaded, the reader contains a `result` property with our file as a data URL. A data URL represents the file’s data as an encoded string. You can read more about this [here](https://developer.mozilla.org/en-US/docs/Web/API/FileReader/readAsDataURL).

We will inform our parent component about this value by emitting a custom event with this value.

```html
<script>
export default {
  methods: {
    changeImage(event) {
      const selectedFile = event.target.files[0];
      if (selectedFile) {
        const reader = new FileReader();

        reader.addEventListener('load', () => {
          this.$emit('imageChanged', reader.result)
        });

        reader.readAsDataURL(selectedFile);
      }
    }
  }
}
</script>
```
