Initialize SDK
Before you can use Appwrite, you need to create the Appwrite Client and set the project ID and endpoint. The client is then used to create services like Databases and Account, so they all point to the same Appwrite project.
Create a function to build services you need in a file like src/lib/server/appwrite.js and exporting the instances.
As part of the function, set the current user's session if they are logged in. This is done by accessing the session cookie from the request and calling the setSession(session) with the cookie value.
Appwrite client security
Notice that createAppwriteClient returns a new instance of the Appwrite Client. When using Appwrite in server-integrations, it's important to never share a Client instance between two requests. Doing so could create security vulnerabilities.
// src/lib/server/appwrite.js
import { Client, Account } from 'node-appwrite';
import { APPWRITE_KEY } from '$env/static/private';
import { PUBLIC_APPWRITE_ENDPOINT, PUBLIC_APPWRITE_PROJECT } from '$env/static/public';
export const SESSION_COOKIE = 'my-custom-session';
export function createAdminClient() {
const client = new Client()
.setEndpoint(PUBLIC_APPWRITE_ENDPOINT)
.setProject(PUBLIC_APPWRITE_PROJECT)
.setKey(APPWRITE_KEY); // Set the Appwrite API key!
// Return the services we want to use.
return {
get account() {
return new Account(client);
}
};
}
export function createSessionClient(event) {
const client = new Client()
.setEndpoint(PUBLIC_APPWRITE_ENDPOINT)
.setProject(PUBLIC_APPWRITE_PROJECT);
// Extract our custom domain's session cookie from the request
const session = event.cookies.get(SESSION_COOKIE);
if (!session) {
throw new Error("No user session");
}
client.setSession(session);
// Return the services we want to use.
return {
get account() {
return new Account(client);
}
};
}
Environment variables
APPWRITE_KEY, PUBLIC_APPWRITE_ENDPOINT and PUBLIC_APPWRITE_PROJECT_ID are environment variables that are exported in your project's .env file.
For example, your .env might look something similar to this.
APPWRITE_KEY=<YOUR_API_KEY>
PUBLIC_APPWRITE_ENDPOINT=https://cloud.appwrite.io/v1
PUBLIC_APPWRITE_PROJECT=<PROJECT_ID>
The PUBLIC_APPWRITE_ENDPOINT is the endpoint of your Appwrite project, and the PUBLIC_APPWRITE_PROJECT is the ID of the project you want to use. You can get the values for these variables from the Appwrite console.
The APPWRITE_KEY is an Appwrite API key with the necessary permissions to read and write accounts and sessions.
For this tutorial you'll need an API key with the following scopes:
| Category | Required scopes | Purpose |
| Sessions | sessions.write | Allows API key to create, update, and delete sessions. |
