Prerequisites
Before starting the project make sure to install the following utilities:
Creating a new Svelte application
Let's create a fresh Svelte application so that we can go through all the steps together.
Step 1
Create new project.
npm create svelte@latest my-project
cd my-project
Step 2
Install all dependencies.
npm install
Installing and configuring Tailwind CSS and Tailwind Elements
Step 1
Install Tailwind CSS
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init tailwind.config.cjs -p
Step 2
Add the paths to all of your template files in your
tailwind.config.cjs file.
/** @type {import('tailwindcss').Config} */
module.exports = {
content: [
"./src/**/*.{html,js,svelte,ts}",
"./node_modules/tw-elements/dist/js/**/*.js"
],
theme: {
extend: {},
},
darkMode: "class",
plugins: [require("tw-elements/dist/plugin.cjs")]
}
Step 3
In your svelte.config.js file, import
vitePreprocess to enable processing style blocks
as PostCSS.
import adapter from '@sveltejs/adapter-auto';
import { vitePreprocess } from '@sveltejs/kit/vite';
/** @type {import('@sveltejs/kit').Config} */
const config = {
kit: {
adapter: adapter()
},
preprocess: vitePreprocess()
};
export default config;
Step 4
Create a ./src/app.css file and add the
@tailwind directives for each of Tailwind’s layers.
@tailwind base;
@tailwind components;
@tailwind utilities;
Step 5
Attach the Roboto font in app.html.
<link
href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700,900&display=swap"
rel="stylesheet" />
Step 6
Create a ./src/routes/+layout.svelte file and import the
newly-created app.css file.
<script>
import "../app.css";
</script>
<slot />
Step 7
Install Tailwind Elements.
npm install tw-elements
Step 8
Create file +page.svelte in src directory and then
import components which are you intend to use and necessary function
initTE. Initialize initTE in a lifecycle method.
<script>
import { onMount } from "svelte";
import { Datepicker, Input, initTE } from "tw-elements";
onMount(() => {
initTE({ Datepicker, Input });
});
</script>
<div
class="relative mb-3"
data-te-datepicker-init
data-te-input-wrapper-init>
<input
type="text"
class="peer block min-h-[auto] w-full rounded border-0 bg-transparent px-3 py-[0.32rem] leading-[1.6] outline-none transition-all duration-200 ease-linear focus:placeholder:opacity-100 peer-focus:text-primary data-[te-input-state-active]:placeholder:opacity-100 motion-reduce:transition-none dark:text-neutral-200 dark:placeholder:text-neutral-200 dark:peer-focus:text-primary [&:not([data-te-input-placeholder-active])]:placeholder:opacity-0"
placeholder="Select a date" />
<label
for="floatingInput"
class="pointer-events-none absolute left-3 top-0 mb-0 max-w-[90%] origin-[0_0] truncate pt-[0.37rem] leading-[1.6] text-neutral-500 transition-all duration-200 ease-out peer-focus:-translate-y-[0.9rem] peer-focus:scale-[0.8] peer-focus:text-primary peer-data-[te-input-state-active]:-translate-y-[0.9rem] peer-data-[te-input-state-active]:scale-[0.8] motion-reduce:transition-none dark:text-neutral-200 dark:peer-focus:text-primary"
>Select a date</label
>
</div>
Initializing via JS
By default all components have autoinit which means they are initialized by data attributes. But if you want to make init by JavaScript - there is also possibility to do that.
Step 1
Import library and initialize components in lifecycle method.
<script>
import { onMount } from "svelte";
import { Datepicker, Input } from "tw-elements";
onMount(() => {
const myInput = new Input(document.getElementById("myDatepicker"));
const options = {
format: "dd-mm-yyyy",
};
const myDatepicker = new Datepicker(
document.getElementById("myDatepicker"),
options
);
});
</script>
<div class="relative mb-3" id="myDatepicker">
<input
type="text"
class="peer block min-h-[auto] w-full rounded border-0 bg-transparent px-3 py-[0.32rem] leading-[1.6] outline-none transition-all duration-200 ease-linear focus:placeholder:opacity-100 peer-focus:text-primary data-[te-input-state-active]:placeholder:opacity-100 motion-reduce:transition-none dark:text-neutral-200 dark:placeholder:text-neutral-200 dark:peer-focus:text-primary [&:not([data-te-input-placeholder-active])]:placeholder:opacity-0"
placeholder="Select a date" />
<label
for="floatingInput"
class="pointer-events-none absolute left-3 top-0 mb-0 max-w-[90%] origin-[0_0] truncate pt-[0.37rem] leading-[1.6] text-neutral-500 transition-all duration-200 ease-out peer-focus:-translate-y-[0.9rem] peer-focus:scale-[0.8] peer-focus:text-primary peer-data-[te-input-state-active]:-translate-y-[0.9rem] peer-data-[te-input-state-active]:scale-[0.8] motion-reduce:transition-none dark:text-neutral-200 dark:peer-focus:text-primary"
>Select a date</label
>
</div>
