Building a Complete To-Do App with SvelteKit: Taking Your Skills to the Next Level
Hello again, passionate developers! Our journey through Svelte's wonders has been remarkable, but the adventure continues. Today, we're stepping up our game by creating a full-fledged to-do app using the cutting-edge SvelteKit framework. Brace yourself for a transformative experience as we craft an interactive web app from scratch!
Crafting a User-Friendly To-Do App
Our focus now shifts to the creation of a user-friendly to-do app, a quintessential project in web development. Leveraging the power of SvelteKit, we'll witness firsthand how effortlessly we can design engaging interfaces and manage user interactions.
Getting Started with SvelteKit
Before diving into the details, let's set up our project using SvelteKit, the future-oriented framework designed for a seamless developer experience.
- Initialize a new SvelteKit project:
npm create svelte@latest my-todo-app
You will be prompted to select the SvelteKit Demo App and other options.
Choose the "Skeleton project" option and proceed to the next prompt.
Choose:
Yes, using JavaScript with JSDoc comments & Add ESLint for code linting
Navigate to our newly initialized app and install the required dependencies:
cd my-app
npm install
Now, run the command below to launch your project:
npm run dev -- --open
This will open a browser window with your empty SvelteKit app, as seen below:
Congratulations! You've now set up your SvelteKit project. Let's dive into creating the to-do app.
Building the To-Do App
With the project foundation laid, it's time to begin crafting our to-do app. Open the src/routes/+page.svelte file and replace its content with the following:
<script>
let tasks = [];
let newTask = '';
function addTask() {
if (newTask) {
tasks = [...tasks, newTask];
newTask = '';
}
}
function removeTask(index) {
tasks.splice(index, 1);
tasks = [...tasks]; // Update the tasks array to trigger reactivity
}
</script>
<main>
<h1>SvelteKit To-Do App</h1>
<div class="add-task">
<input class="task-input" bind:value={newTask} placeholder="Add a new task" />
<button class="add-button" on:click={addTask}>Add</button>
</div>
<ul class="task-list">
{#each tasks as task, index (task)}
<li class="task-item">
{task}
<button class="remove-button" on:click={() => removeTask(index)}>Remove</button>
</li>
{/each}
</ul>
</main>
<style>
main {
font-family: Arial, sans-serif;
text-align: center;
margin: 20px;
}
h1 {
color: #333;
}
.add-task {
margin-bottom: 20px;
}
.task-input {
padding: 5px;
border: 1px solid #ccc;
border-radius: 5px;
}
.add-button {
padding: 5px 10px;
background-color: #007bff;
color: white;
border: none;
border-radius: 5px;
cursor: pointer;
}
.task-list {
list-style-type: none;
padding: 0;
}
.task-item {
display: flex;
align-items: center;
justify-content: space-between;
padding: 10px;
border: 1px solid #ccc;
border-radius: 5px;
margin-bottom: 10px;
}
.remove-button {
background-color: #dc3545;
color: white;
border: none;
border-radius: 5px;
cursor: pointer;
}
</style>
Running the SvelteKit App
With the to-do app in place, let's witness its magic:
Start the development server:
npm run dev
Open your browser and navigate to http://127.0.0.1:5173.
