▶ Introduction
I've been a fan of Svelte for a long time now and started every project I came up with in 2020 with the sveltejs/template. While working on these ideas, I discovered a self-hosted Firebase alternative called Appwrite.
❓ What is Appwrite?
Appwrite is an open-source backend-as-a-service server that abstracts and simplifies complex and repetitive development tasks behind a very simple to use REST API. Appwrite aims to help you develop your apps faster and in a more secure way.
If you haven't heard of Appwrite before, you should really check it out! 👀
If you ask yourself, why you should use Appwrite over something like Firebase, I've written down my reasons here:
Why I moved from BaaS to Appwrite (self-hosted Backend)

Hooked by the concept, I started contributing to Appwrite, became part of its community, and in 2021 I became a fulltime Core Member.
Using the Javascript SDK worked right away, but didn't really fit the component driven approach of Svelte. So I sat down, inspired by sveltefire, and worked out a collection of components which feel at home in Svelte projects. This resulted in the project svelte-appwrite
.
🔎 Comparison
Enough talking, let's start with a code comparison between appwrite
and svelte-appwrite
:
Short isn't always better, except in this case. Let's take a look at the shorter variant, the svelte-appwrite
one:
<script>
import { Appwrite, User, AuthEmail } from "svelte-appwrite";
const config = {
endpoint: "http://localhost/v1",
project: "5ffc6c043586d",
};
let email = "";
let password = "";
</script>
<Appwrite {...config}>
<User let:user let:actions>
<p>Hello {user.name}!</p>
<button on:click={actions.logout}>Logout</button>
<div slot="error">
<AuthEmail let:authorize on:success={actions.reload}>
<input type="text" bind:value={email} />
<input type="text" bind:value={password} />
<button on:click={authorize(email, password)}>
Login
</button>
</AuthEmail>
</div>
</User>
</Appwrite>
This small snippet handles Initialization and Authentication via E-Mail with an Appwrite project for you with just a few lines.
🧬 Let's break it down
<Appwrite {...config}>
The <Appwrite />
component initializes the SDK for your Appwrite project and must wrap every svelte-appwrite
component. You can simply spread a configuration like this:
const config = {
endpoint: "http://localhost/v1",
project: "5f4938898667e",
locale: "de"
};
<User let:user let:actions>
The <User/>
component requests the currently logged in user and provides you 2 let:directives:
- let:user
- let:actions
The user
directive provides you with the currently logged-in user and actions
with following set of functions:
reload()
logout()
logoutFrom(session: string)
logoutAll()
By default, everything inside the <User />
component is only shown when a user is logged in. By using the error
slot we can show content when a user is not logged in.
<User let:user>
<h1>Hello {user.name}!</h1>
<div>{user.email}</div>
<div slot="error">
You are not logged in!
</div>
<div slot="loading">
Loading...
</div>
</User>
<AuthEmail let:authorize on:success>
The last component we used lets users authenticate via e-mail with the provided authorize(email, password)
method. This component can also emit success
and failure
events.
<AuthEmail let:authorize on:success={actions.reload}>
<input type="text" bind:value={email}>
<input type="text" bind:value={password}>
<button on:click={authorize(email,password)}>Login</button>
</AuthEmail>
As you can see in the example above, the on:success
event points to the reload()
function from <User />
. This way, when a successful login happens, the component will fetch the user from Appwrite and renders the default slot.

👆 Conclusion
Of course, there are many more components that cover all the functionalities (except teams, that's coming) of Appwrite. This library allows you to kickstart ideas in no time with Svelte. If you have any feedback you'd like to share with me, I'd be glad to read your comments!
To support this claim, a tutorial series will be published in the coming weeks, in which I will present all aspects of this library and Appwrite itself by building an Instagram clone.

looks really nice for dev experience. appwrite seems promising too, but I'm missing realtime functionalities and offline capabilities for the database. hope they will be added sometime.
Hey Manuel, this is Eldad from Appwrite 👋 realtime features are already a work in progress, you can learn more here: github.com/appwrite/appwrite/pull/692 - got lots of cool plans on that department. We'll also be sharing some more tutorials about how to accomplish offline support.
Thanks for your response. Looks awesome, will definitely check it out in the future!
