This is the first episode of "Apps For Your Portfolio" series. In this post, we are going to build a Meditation App with my favorite front-end framework Vue.js.

<a name="table-of-content"></a>
## 1.0 / Setup
   * [ 1.1 | Install Vue ](#vue-3-installation)
   * [ 1.2 | Creating a new project ](#vue-3-new-project)
   * [ 1.3 | Install Vuex & Sass Loader ](#vue-3-vuex-sasss-loader)

## 2.0 / Assets
   * [ 2.1 | Images ](#assets-images)
   * [ 2.2 | Sounds ](#assets-sounds)
   * [ 2.3 | Svg ](#assets-svg)
   * [ 2.4 | Videos ](#assets-videos)

## 3.0 / Components
   * [ 3.1 | ContainerBackground.vue ](#container-background)
   * [ 3.2 | ContainerPopUp.vue ](#container-pop-up)
   * [ 3.3 | Sound.vue ](#sound)
   * [ 3.4 | ContainerTimer.vue ](#container-timer)
   * [ 3.5 | ContainerLinks.vue ](#container-links)

## [ 1.1 ] Vue 3 Config <a name="vue-3-installation"></a>

```
# Install latest stable of Vue

yarn global add @vue/cli
```

## [ 1.2 ] Creating a new project <a name="vue-3-new-project"></a>

```
# Create a New Vue Application name 'meditation-app'

vue create meditation-app
cd meditation-app
yarn
```

## [ 1.3 ] Install Vuex & Sass Loader <a name="vue-3-vuex-sasss-loader"></a>

We also need to install sass-loader pre-processors to animate easily our future timer. If you don't know Sass is an extension of CSS that enables you to use things like variables, nested rules, inline imports and more. 

You can find more information on the official documentation :

https://sass-lang.com/documentation

```
yarn add -D sass-loader sass
```

To help my code organized in this application. I decide to use the state management pattern Vuex.

```
yarn add vuex@next --save
```

To use Vuex, we need also to change main.js and create a new folder name "store" with four files :

- index.js
- actions.js
- mutations.js
- getters.js

```js
# ../src/main.js

import { createApp } from 'vue';

import App from './App.vue';
import store from './store/index.js'

const app = createApp(App);

app.use(store);

app.mount('#app');

```

```
src
|
|-- store |-- actions.js
          |-- getters.js 
          |-- index.js
          |-- mutations.js
```

To build our meditation application, let's initialize all states, actions, mutations and getters as following :

'isPlaying'
'timeSelected'
'vibeSelected'
'step'
'choices'

```js
# ../store/index.js

import { createStore } from 'vuex'

import rootMutations from './mutations.js'
import rootActions from './actions.js'
import rootGetters from './getters.js'

const store = createStore({
  state() {
    return {
      isPlaying: false,
      timeSelected: 0,
      vibeSelected: { value: 'bird'},
      step: 0,
      choices: [
        { 
          id: 1,
          name: '10 minutes',
          imgSrc: require("@/assets/images/Bouton_10_minutes.png"),
          category: 'timer',
          value: 600,
        },
        { 
          id: 2,
          name: '20 minutes',
          imgSrc: require("@/assets/images/Bouton_20_minutes.png"),
          category: 'timer',
          value: 1200,
        },
        { 
          id: 3,
          name: '30 minutes',
          imgSrc: require("@/assets/images/Bouton_30_minutes.png"),
          category: 'timer',
          value: 1800,
        },
        {
          id: 4,
          name: 'In The Space',
          imgSrc: require("@/assets/images/Bouton_Space.png"),
          category: 'vibe',
          value: 'space',
        },
        {
          id: 5,
          name: 'On The Beach',
          imgSrc: require("@/assets/images/Bouton_Beach.png"),
          category: 'vibe',
          value: 'beach',
        },
        {
          id: 6,
          name: 'Under The Rain',
          imgSrc: require("@/assets/images/Bouton_Rain.png"),
          category: 'vibe',
          value: 'rain',
        },
      ]
    }
  },
  mutations: rootMutations,
  actions: rootActions,
  getters: rootGetters,
});

export default store;

```

```js
# ../src/store/actions.js

export default {
  changeTimer(context, time) {
    context.commit('changeTimer', time)
  },
  changeVibe(context, vibe) {
    context.commit('changeVibe', vibe)
  },
  changeStep(context) {
    context.commit('changeStep')
  },
  activeIsPlaying(context) {
    context.commit('activeIsPlaying')
  },
  togglePlayPause(context) {
    context.commit('togglePlayPause')
  },
}
```

```js
# ../src/store/mutations.js

export default {
  changeTimer(state, time) {
    state.timeSelected = time
  },
  changeVibe(state, vibe) {
    state.vibeSelected = vibe 
  },
  changeStep(state) {
    state.step++
  },
  activeIsPlaying(state) {
    state.isPlaying = true
  },
  togglePlayPause(state) {
    state.isPlaying = !state.isPlaying
  },
}
```

```js
# ../src/store/getters.js

export default {
  timeSelected(state) {
    return state.timeSelected
  },
  vibeSelected(state) {
    return state.vibeSelected
  },
  step(state) {
    return state.step
  },
  choices(state) {
    return state.choices
  },
  isPlaying(state) {
    return state.isPlaying
  }
}
```

Great ! The next step is importing all assets.

Let's create four new folders in assets :
- images,
- sounds,
- svg,
- videos,

```
src
|
|-- assets --|-- images
             |-- sounds
             |-- svg
             |-- videos

```

## [ 2.1 ] Assets Images <a name="assets-images"></a>

Maybe you didn't notice but the state 'choices' is an array of objects. Each object has an attribute 'imgSrc' as this example.

```js
{
  id: 6,
  name: 'Under The Rain',
  imgSrc: require("@/assets/images/Bouton_Rain.png"),
  category: 'vibe',
  value: 'rain',
},
``` 

As you can see it **'require("@/assets/images/Bouton_Rain.png")'** is the path to import the file 'Bouton_Rain.png'

You need to create six illustrations relative to timer and to background video as following :

![Button Timer](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/j3tdx1inhr5vsa4u0d9d.png)

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ej5l86150te6ey5fir6j.png)

I took some image from https://unsplash.com/ and resizing it to 375px width | 250px height.

```
src
|
|-- assets --|-- images -- Bouton_10_minutes.png
                       |-- Bouton_20_minutes.png
                       |-- Bouton_30_minutes.png
                       |-- Bouton_Beach.png
                       |-- Bouton_Rain.png
                       |-- Bouton_Space.png

```

## [ 2.2 ] Assets Sounds <a name="assets-sounds"></a>

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fn5c7kdccrnl1rsnk0f6.png)

Download four sound effects from https://www.videvo.net/ and import them in sounds folder.


```
src
|
|-- assets -- sounds -- beach.mp3
                    |-- calmSpace.mp3
                    |-- rain.mp3
                    |-- songOfBirds.mp3

```
## [ 2.3 ] Assets Svg <a name="assets-svg"></a>

Create eight components in svg folder :

```html
src
|
|-- assets -- svg -- BeachSvg.vue
                 |-- GithubSvg.vue
                 |-- LinkedInSvg.vue
                 |-- PauseSvg.vue
                 |-- PlaySvg.vue
                 |-- PraySvg.vue
                 |-- RainSvg.vue
                 |-- SpaceSvg.vue

```

## [ 2.4 ] Assets Videos <a name="assets-videos"></a>

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qkxte3hnczxvws039jq4.png)

From https://www.videvo.net/ download and import 4 background videos in assets.

```
src
|
|-- assets -- videos -- bird.mp4
                    |-- rain.mp4
                    |-- space-galaxy.mp4
                    |-- sunny-beach.mp4
```

All assets are imported now ! Let's create all components 🙂

## [ 3.1 ] ContainerBackground.vue <a name="container-background"></a>

Add a new folder "container" in "../src/components" and create a new component "ContainerBackground.vue"

```html
# ../src/components/container/ContainerBackground.vue

<template>
  <div class="video-container">
    <video
      v-if="vibeSelected === 'space'"
      class="video-wrapper"
      autoplay
      muted
      loop
    >
      <source
        :src="updateBackground"
        type="video/mp4"
        rel='preload'
      />
    </video>
    <video
      v-if="vibeSelected === 'beach'"
      class="video-wrapper"
      autoplay
      muted
      loop
    >
      <source
        :src="updateBackground"
        type="video/mp4"
        rel='preload'
      />
    </video>
    <video
      v-if="vibeSelected === 'rain'"
      class="video-wrapper"
      autoplay
      muted
      loop
    >
      <source
        :src="updateBackground"
        type="video/mp4"
        rel='preload'
      />
    </video>
    <video
      v-if="vibeSelected === 'bird'"
      class="video-wrapper"
      autoplay
      muted
      loop
    >
      <source
        :src="updateBackground"
        type="video/mp4"
        rel='preload'
      />
    </video>
  </div>  
</template>

<script>
export default {
  computed: {
    updateBackground() {
      if (
          this.vibeSelected === 'space' || 
          this.vibeSelected === null
        ) 
      {
        return require("@/assets/videos/space-galaxy.mp4")
      } else if (this.vibeSelected === 'beach') {
        return require("@/assets/videos/sunny-beach.mp4")
      } else if (this.vibeSelected === 'rain') {
        return require("@/assets/videos/rain.mp4")
      } else {
        return require("@/assets/videos/bird.mp4")
      }
    },
    vibeSelected() {
      return this.$store.getters['vibeSelected'].value
    }
  },
}
</script>

<style>
.video-container {
  position: absolute;
  z-index: -5;
  display: flex;
  width: 100vw;
  height: 100vh;
}

.video-wrapper {
  position: absolute;
  width: 100%;
  height: auto;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
  z-index: -10;
  overflow: none;
}

@media (min-aspect-ratio: 16/9) {
  .video-wrapper {
    width:100%;
    height: auto;
  }
}

@media (max-aspect-ratio: 16/9) {
  .video-wrapper { 
    width:auto;
    height: 100%;
  }
}
</style>

```
This component change background video depending of user choice.

## [ 3.2 ] ContainerPopUp.vue <a name="container-pop-up"></a>

Unlike the 'ContainerBackground.vue' 'ContainerPopUp.vue' is a nested component. It allow us to encapsulate functionality and easily reuse them in multiple places in this application.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ll30fotjc1inv9aw25s4.png)

```
ContainerPopUp.vue
   |-- ContainerSelector.vue
                     |-- Selector.vue
```

Firstly, Let's create 'ContainerPopUp.vue'

```html
# ../src/components/container/ContainerPopUp.vue

<template>
  <div v-if="step < 2" class="overlay">
    <div class="popup">
      <PraySvg
        size="80"
        color="white"
      />
      <h1>Welcome to<br> Vibe Meditation App</h1>
      <ContainerSelector
        :question="questionDisplaying"
      >
        <Selector
          v-if="step === 0"
          :size="'normal'"
          :mode="'timer'"
        />
        <Selector 
           v-if="step > 0"
          :size="'normal'"
          :mode="'vibe'"
        />
      </ContainerSelector>
    </div>
  </div>
</template>

<script>
import { mapGetters } from 'vuex'

import PraySvg from '@/assets/svg/PraySvg'
import ContainerSelector from '@/components/container/ContainerSelector'
import Selector from '@/components/Selector'

export default {
  components: {
    PraySvg,
    ContainerSelector,
    Selector
  },
  computed: {
    questionDisplaying() {
      if (this.step === 0) {
        return 'How long do you want to meditate ?' 
      } else {
        return 'Where do you want to meditate ?'
      }
    },
    ...mapGetters([
      'timeSelected',
      'vibeSelected',
      'step'
    ])
  }
}
</script>

<style scoped>
.overlay {
  position: absolute;
  width: 100vw;
  height: 100vh;
}

.popup {
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  position: absolute;
  width: 600px;
  height: 600px;
  top: 50%; 
  right: 50%;
  transform: translate(50%,-50%);
  background-color: rgba(5, 5, 5, 0.900);
  border-radius: 15px;
  box-shadow: 1px 1px rgba(255, 255, 255, 0.200);
  color: white;
}

.bouton-primary {
  width: 200px;
  line-height: 30px;
  border-radius: 5px;
  margin: 30px;
  background-color: rgba(193, 99, 89, 0.800);
  border: rgba(193, 99, 89, 0.800);
  color: aliceblue;
}

.bouton-off {
  width: 200px;
  line-height: 30px;
  border-radius: 5px;
  margin: 30px;
  background-color: rgba(35, 35, 35, 0.500);
  border: white;
  color: aliceblue;
}
</style>

```
Second step is creating 'ContainerSelector.vue'

```html
# ../src/components/container/ContainerSelector.vue

<template>
  <section class="selector-container">
    <h3>{{ question }}</h3>
    <div class="selector-wrapper">
      <slot></slot>
    </div>
  </section>
</template>

<script>
export default {
  props: ['question']
}
</script>

<style>
.selector-container {
  position: relative;
  display: flex;
  flex-direction: column;
  width: 500px;
  justify-content: center;
}

h3, .selector-container {
  margin-bottom: 50px;
}

.selector-wrapper {
  display: flex;
  flex-wrap: wrap;
  flex-direction: row; 
  justify-content: space-around;
  width: 100%;
}
</style>

```
Third step is creating 'Selector.vue'

```html
# ../src/components/Selector.vue

<template>
  <div
    v-for="choice in filteredChoices"
    :key="choice.id"
    @click="selectChoice(choice.id)"
    class="choice-card"
    :class="hideUnselectedImg(choice.id)"
  >
    <img
      :src="choice.imgSrc"
      :alt="choice.name"
    >
    <label 
      :for="choice.name"
      :style="fontSizeDynamic(choice.id)"
    >
      {{ choice.name }}
    </label>
  </div>
</template>

<script>
import { mapGetters } from 'vuex'

export default {
  props: ['size', 'mode'],
  methods: {
    hideUnselectedImg(id) {
       if (this.vibeSelected.id === id) {
        return 'img-selected'
       }
       else {
         return 'img-unselected'
       }
    },
    selectChoice(id) {
      let index = this.choices.findIndex(x => x.id === id);
      if (this.step === 0) {
        let timeSelecting = {
          id: this.choices[index].id,
          value: this.choices[index].value
        }
        this.$store.dispatch('changeTimer', timeSelecting)
        this.$store.dispatch('changeStep')
      } else {
        let vibeSelecting = {
          id: this.choices[index].id,
          value: this.choices[index].value
        }
        this.$store.dispatch('changeVibe', vibeSelecting)
        this.$store.dispatch('changeStep')
        this.$store.dispatch('activeIsPlaying')
      }
    },
    fontSizeDynamic(id) {
       if (this.timeSelected.id === id || this.vibeSelected.id === id) {
        return 'font-weight: bold;'
       }
       else {
         return 'font-weight: normal;'
       }
    },
  },
  computed: {
    filteredChoices() {
      return this.choices.filter(choice => 
        {
          if 
            ( 
              this.mode === 'timer' &&
              choice.category.includes('timer')
            )
          {
            return true
          }
          if 
            (
              this.mode === 'vibe' &&
              choice.category.includes('vibe')
            ) 
          {
            return true;
          }
        }
      )
    },
    ...mapGetters([
      'timeSelected',
      'vibeSelected',
      'step',
      'choices'
    ])
  }
}
</script>

<style scoped>
.choice-card {
  cursor: pointer;
  display: flex;
  flex-direction: column;
}

.img-selected {
  display: none;
}

img:hover {
  opacity: 1;
}

img {
  opacity: 0.5;
  height: 100px;

Perfect ! With this first nested component, the user can select time of meditation and the virtual area where he wants to meditate.

## [ 3.3 ] Sound.vue <a name="sound"></a>

Previously, we created files which allow us to change background video. For a better User Experience, we need to implement sound effects !

Let's create a new simple component 'Sound.vue'

```html
# ../src/components/Sound.vue

<template>
  <audio :src="updateSound" preload="auto" autoplay loop ref="audioPlayer" />
</template>

<script>
export default {
  computed: {
    updateSound() {
      if (this.vibeSelected === 'space') {
        return require("@/assets/sounds/calmSpace.mp3")
      } else if (this.vibeSelected === 'beach') {
        return require("@/assets/sounds/beach.mp3")
      } else if (this.vibeSelected === 'rain') {
        return require("@/assets/sounds/rain.mp3")
      } else {
        return require("@/assets/sounds/songOfBirds.mp3")
      }
    },
    vibeSelected() {
      return this.$store.getters['vibeSelected'].value
    }
  },
}
</script>

```

## [ 3.4 ] ContainerTimer.vue <a name="container-timer"></a>

Background Video, sound effects so what's next ? Timer Animation of course.

Let's create a new nested component 'ContainerTimer.vue'

```
ContainerTimer.vue
   |-- TimerHeader.vue
   |-- Timer.vue
   |-- TimerRemaining.vue
   |-- VibeSwitcher.vue

```

```html
# ../src/components/container/ContainerTimer.vue

<template>
  <section
    v-if="step === 2"
    class="container"

    <VibeSwitcher />

      'step',

    ]),
    timeLeft() { 
      if (this.timerInterval === null) {
        return 0
      } else if (this.timePassed === this.timeSelected.value) {
        clearInterval(this.timerInterval)
        this.$store.dispatch('changeVibe', { value: 'bird' })
        this.$store.dispatch('changeStep')
        console.log('step : ', this.step)
        return 0
      } else {
        return this.timeSelected.value - this.timePassed
      }
    },
  },
  watch: {
    isPlaying(isInProgress) {
      if (isInProgress) {
        this.timerInterval = setInterval(() => (this.timePassed += 1), 1000);
      } else {
        clearInterval(this.timerInterval)
      }

What do you think ? Nice view right ?

## [ 3.5 ] ContainerLinks.vue <a name="container-links"></a>

When Timer is over, I prepared a last view with my linkedIn, Github and my Portfolio.

You just need to replace links and Svg in this last component.

```html
# ../src/components/container/ContainerLinks.vue

<template>
  <div 
    v-if="step === 3"
    class="container-end"

        <GithubSvg :size="'80'" :color="'white'" />
        <span>Github</span>

      <a

Everything is already now ! We need to import all components in App.vue

```html

export default {
  name: "App",
  components: {
    ContainerPopUp,
    ContainerBackground,
    ContainerTimer,
    ContainerLinks,
    Sound
  },
};

There are so many other way to build this meditation application.

I hope this will help a beginner in Vue. See you in the next post of this series "Portfolio Apps".

You can try this meditation-app here :
