# Introduction 🥳


In this blog, we'll guide you to create the About component for our portfolio website and it looks something like this


What'll be covered in this blog 🤓

Display image on website
Props in Svelte

Let's start 🤖
Create About component

Similar to our NavBar in part 2, we'll create an About.svelte in our components folder


NOTE: Don't forget to import our component in App.svelte - our main Svelte file

Display an Image on our website

To display an image, we'll need to use the <img src="" alt=""> </img> in HTML, but we first need to have an image link, it can be image link from the internet or your local image files

EX: Here's an online image link from Unsplash ( website for free images )
https://images.unsplash.com/photo-1586115457457-b3753fe50cf1?ixlib=rb-4.0.3&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=1576&q=80

EX: Here's a local image ( We downloaded a .svg image and put it in our assets folder )

Now, let's try to import our local image in our About.svelte
<script>
  import frank from "../assets/frank.svg"; // Import our local image
</script>

<section>
  <div class="container__about" id="About">
 
    <img width={180} height={123} src={frank} alt="" />
    <p class="header--small">Hi, I'm Frank </p>
    <p class="header--big">WELCOME TO MY PORTFOLIO</p>
  </div>
</section>

<style>
  .container__about {
    display: flex;
    flex-direction: column;
    align-items: center;
    margin-top: 10rem;
  }
  .header--small {
    font-size: 1.5rem;
    margin: 2rem 0 0 0;
    font-weight: 600;
  }

  .header--big {
    font-size: 2rem;
    color: #2C91C6;
    font-weight: 700;
  }
</style>
Then, after you save file, you should see the an image of Frank along with the welcome message 🦈
BONUS: Props in Svelte 👀
In any real application, you'll need to pass data from one component down to its children. To do that, we need to declare properties, generally shortened to 'props'. In Svelte, we do that with the export keyword
Let's see that with some code:
Passing props

App.svelte

<script>
  import About from "./components/About.svelte";
  import NavBar from "./components/NavBar.svelte";
</script>

<main>
  <NavBar/>
 
  <About name="Frank"/>
</main>

<style>
	main {
		margin: 1rem;
		font-size: 1.25rem;
	}
</style>
 
Receiving props

About.svelte

<script>
  export let name; // receive props ```name```
  import frank from "../assets/frank.svg";
</script>

<section>
  <div class="container__about" id="About">
    <img width={180} height={123} src={frank} alt="" />
   
    <p class="header--small">Hi, I'm {name}</p> 
    <p class="header--big">WELCOME TO MY PORTFOLIO</p>
  </div>
</section>

<style>
  .container__about {
    display: flex;
    flex-direction: column;
    align-items: center;
    margin-top: 10rem;
  }
  .header--small {
    font-size: 1.5rem;
    margin: 2rem 0 0 0;
    font-weight: 600;
  }

  .header--big {
    font-size: 2rem;
    color: #2C91C6;
    font-weight: 700;
  }
</style>
So, now if you change the props name into another string, it'll update the name in our About.svelte dynamically, so you can see that props will be helpful if we want to update dynamically instead of hard-coding the string 🥰
Now, you've successfully made the About component 🤩 🤩 You can always check the full code HERE

Dev Portfolio Project Part 3 - About

Introduction 🥳

===============

In this blog, we'll guide you to create a navigation bar for your website

Prerequisites 🥸

Cloned the website and able to run it locally ( If not: check previous part )

What you will learn 🤓

Brainstorming about website layout
Project folder + file structures
Components
Svelte #each loop
JavaScript Date object
... many more

Let's Start 🤖
I. Website Layout 🌐
Here's what our final website will look like

Here's how it'll be broken down before jumping to code

II. Let's take a look at our project structure 👀
Here's what you will see when first start

Although there're lots of folders to look at, we only focus on the "src" folder

Here're the main files/folders you need to know

App.svelte is our main Svelte file
App.cssis our main global CSS file
lib folder contains our components which we will rename to "components" later on instead

Let's do a quick clean up by removing things we don't need
App.svelte: Delete everything but the tags

App.css: Delete place-items:center ( line 30 ) since it'll make everything become center and we don't want that

lib : Rename to components

Delete Counter.svelte

III. Good job, now let's start making our NavBar 🥳

Here's the NavBar we want to make:


About, Experiences, Projects are link to our sections, Thursday is the current date ( we'll use JavaScript Date Object to make this )



In components folder, create a file called NavBar.svelte and add the necessary tags as follow


Note: You don't need to have all tags as below, you can even have just a <nav> </nav> tag and it's still valid in Svelte


Now, let's see how component works in Svelte

Type anything between <nav> </nav> ( because if you want to display something, it has to be within a HTML tag ) in your NavBar.svelte file and save it


<p> </p> tag stands for paragraph



Now, if you run your website using npm run dev, it won't display that words because you have to import it in App.svelte - our main Svelte file


Tada !! that's how you import a component , when you run your website again, you should see it display NavBar content

Now, let's go back to NavBar.svelte and start creating our navigation bar

You can copy paste this code block and read the comments to understand more

<script>

</script>

<nav>
 

     <section class="container__nav" id="/">
        <ol>  
  
           <li>
               <a href='#About' class="nav__item">
                  About
               </a>
          </li>
          <li>
               <a href='#Experiences' class="nav__item">
                 Experiences
               </a>
         </li>
      <li>
          <a href='#Projects' class="nav__item">
            Projects
          </a>
     </li>
   </ol> 
</section>
</nav>

<style>
/* This is CSS style for our navigation bar */
   ol {
    list-style: none;
  }
  li {
    padding: 0;
  }
  .container__nav {
    display: flex;
    justify-content: center;
    align-items: center;
    flex-direction: row;
  }
  .nav__item {
    color: white;
    font-weight: 600;
    font-size: 2rem;
    margin: 0 2rem;
    transition: all 400ms;
  }
  .nav__item:hover {
    color: rgb(0, 157, 255);
  }
  .time {
    color: #1a1a1a;
    font-weight: 700;
    background-color: #2C91C6;;
    padding: 0.35rem;
    margin: 0 2rem;
    border-radius: 12px;
  }
</style>
Now, when you save the file, our NavBar will look nicer

⚠️ BUT, don't you think this block of code is kinda repetitive? we don't want to type the same thing every time we add a new item to our nav bar
<ol class="container__nav" id="/">
  
      <li>
      <a href='#About' class="nav__item">
        About
      </a>
     </li>
     <li>
      <a href='#Experiences' class="nav__item">
        Experiences
      </a>
    </li>
     <li>
      <a href='#Projects' class="nav__item"\>
        Projects
      </a>
     </li>
  </ol>
💡So, what we can do better by using Svelte #each loop, we'll create an Array of Objects that hold our nav items and then loop through every items and render it to the browser

NavBar.svelte

<script>
  // @ts-nocheck
  history.scrollRestoration = "manual" // Prevent automatic scrolling
  const navItems = [
    { title: "About", url: "#About" },
    { title: "Experiences", url: "#Experiences" },
    { title: "Projects", url: "#Projects" },
  ];

</script>

<nav>
  <section class="container__nav" id="/">
    <ol class="container_nav" id="/">
      {#each navItems as { title, url }}
        <li>
          <a href={url} class="nav__item">
            {title}
          </a>
        </li>
      {/each}
    </ol> 
  </section>
</nav>

<style>
   ol {
    list-style: none;
  }
  li {
    padding: 0;
  }
  .container__nav {
    display: flex;
    justify-content: center;
    align-items: center;
    flex-direction: row;
  }
  .nav__item {
    color: white;
    font-weight: 600;
    font-size: 2rem;
    margin: 0 2rem;
    transition: all 400ms;
  }
  .nav__item:hover {
    color: rgb(0, 157, 255);
  }
  .time {
    color: #1a1a1a;
    font-weight: 700;
    background-color: #2C91C6;;
    padding: 0.35rem;
    margin: 0 2rem;
    border-radius: 12px;
  }
</style>
JavaScript Date Object 📆

Display the current date with custom parameters

We can do that in the <script> </script> that allows us to use JavaScript magic
let time = new Date(Date.now()); // Create Date Object
const options = { // We'll need this option for toLocaleDateString() method later on to display on the weekday
  weekday: "long",
};
Then we can display it in our html like this to display current weekday:
<p class="time">{time.toLocaleDateString(undefined, options)}<p>
Here's the full code for NavBar.svelte
<script>
  // @ts-nocheck
  history.scrollRestoration = "manual" // Prevent automatic scrolling
  const navItems = [
    { title: "About", url: "#About" },
    { title: "Experiences", url: "#Experiences" },
    { title: "Projects", url: "#Projects" },
  ];
  let time = new Date(Date.now());
  const options = {
    weekday: "long",
  };
</script>

<nav>
  <section class="container__nav" id="/">
    <ol class="container__nav" id="/">
      {#each navItems as { title, url }}
        <li>
          <a href={url} class="nav__item">
            {title}
          </a>
        </li>
      {/each}
    <p class="time">{time.toLocaleDateString(undefined, options)}</p>
  </ol>
  </section>
</nav>

<style>
   ol {
    list-style: none;
  }
  li {
    padding: 0;
  }
  .container__nav {
    display: flex;
    justify-content: center;
    align-items: center;
    flex-direction: row;
  }
  .nav__item {
    color: white;
    font-weight: 600;
    font-size: 2rem;
    margin: 0 2rem;
    transition: all 400ms;
  }
  .nav__item:hover {
    color: rgb(0, 157, 255);
  }
  .time {
    color: #1a1a1a;
    font-weight: 700;
    background-color: #2C91C6;;
    padding: 0.35rem;
    margin: 0 2rem;
    border-radius: 12px;
  }
</style>

Dev Portfolio Project Part 2 - NavBar

Introduction 🥳

This is a beginner friendly series made by acmDev team with the goal to help beginner developers create their first website using Svelte ( Javascript framework to build website )

What'll be covered in this blog 🤓

Required installation for the project
Setup the project  ( clone the repo )
Run the project locally

Let's start 🤖
A. Technology Installation:

VSCode ( text editor - where you'll code ) - Required
Node.js v16+ ( JavaScript environment to help you install Svelte later on ) - Required

Note for Ubuntu/Tuffix users: Refer to the instructions at the bottom of the page


Svelte Plugins ( after you've downloaded VSCode, open Extensions and search for Svelte to install the plugins - it helps you highlight code and autocomplete with Svelte syntax) - Required
Git ( for collaboration purpose and you'll need to use this in real world but not necessary for this project ) - Optional

B. Setup the project:

Project Template Link

1. Clone the repo ( 2 ways )

Using Git ( You'll need to Download Git first )


Type the command git clone https://github.com/acmCSUFDev/website-template.git in your terminal to clone


Download the ZIP file from this repo ( Beginner Friendly )


2. Open with VSCode

Once you've cloned our website template, UNZIP the folder if you choose method 2, then open the folder you've just unzipped  in VSCode


C. Run the project locally


Have Node.js installed.


In your VSCode, in the project folder, open Terminal and type
npm install


After npm install, you should see a folder called node_modules which indicated you've used npm install correctly


Run your website by typing and click on the link provided
npm run dev



After you click on the link provided, you should see our beautiful Svelte template :) congrats 🤩
Note on installing Node.js on Ubuntu/Tuffix
By default, sudo apt install nodejs will install node v10 which is incompatible with Svelte. To remedy this, first uninstall the existing nodejs and npm installation with sudo apt remove nodejs npm and install Node Version Manager using
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash
Afterwards, restart your terminal to load the new nvm command.
Now run nvm install 16 and nvm use 16 to install and set node v16 as the default version
Run node -v to verify the correct version is now in use
