Hold up! This library is currently experimental, and in early development. Be careful if you intend on using this in production.

Supercharge your Sveltekit + PocketBase project!

Svelte-Pocketbase is the perfect companion to your next Sveltekit + PocketBase project. This library provides declarative components that effortlessly query data from your PocketBase database.

Getting Started

# install svelte-pocketbase with pnpm, npm or yarn
pnpm i -D svelte-pocketbase

PocketBase Store

To get started, instantiate a new pbStore in a +page.svelte or +layout.svelte.

// src/+layout.svelte OR src/+page.svelte

<script>
  import PocketBase from 'pocketbase';
  import { pbStore } from 'svelte-pocketbase';
  import { env } from '$env/dynamic/public';

  pbStore.set(env.PUBLIC_POCKETBASE_URL);
</script>

<slot />

The pbStore is the ultimate marriage of PocketBase and Svelte Writable magic! Simply create an instance of pbStore and you've got a PocketBase instance wrapped up in a shiny svelte store. Need to use it in your app? No problem! Just subscribe to $pbStore and you're good to go.

// src/+page.svelte
<script>
  import { pbStore } from 'svelte-pocketbase';
  let id = "RECORD_ID"

  const record = $pbStore.collection('categories').getOne('RECORD_ID');
</script>

{#await record}
  <span>Loading...</span>
{:then data}
  <pre>{JSON.stringify(data, null, 2)}</pre>
{:catch error}
  <p style="color: red">{error.message}</p>
{/await}

This is a fair amount of boilerplate for simply retrieving a bit of data from your database. Instead, maybe try out one of the data retrieval components, like Record. These components handle all the tedious bits of querying and data retrieval, leaving you free to focus on more important things (like obsessively fine-tuning your Tailwind CSS config).

Components

  • Record
  • List
  • FullList
  • FirstListItem

Every data retrieval component receives a collection prop, and an optional query prop that can be used to sort and filter the results. Each component also contains an error slot that can be used to notify the user.

Retrieving Data

Individual Records by ID

<script>
  import { Record } from 'svelte-pocketbase';
</script>

<Record collection="posts" id="RECORD_ID" let:record >
  <span slot="loading">Loading...</span>
  <pre>{JSON.stringify(record, null, 2)}</pre>
  <span slot="error" let:error>{error}</span>
</Record>

The Record component is intended to retrieve single records from your database by their RECORD_ID.

Simply pass in the name of the collection to the collection prop and a RECORD_ID to the id prop and let the component do the heavy lifting.

You can also pass an HTMLElement into the loading slot in the event that your server is being naughty, and you need to keep your audience captivated with a fancy loading element.

Want to access the data? No problem, just use the handy let:record directive.

As an extra sprinkle of magic, there is no need to fuss about with { #await } blocks. The Record component, along with all other data components handle the async action for you!

Paginated Lists

<script lang="ts">
  import List from '$lib/List.svelte';

  let page = 1;

  function setPage(number: number) {
    page = number;
  }
</script>

<List collection="posts" {page} perPage={2} query={{ sort: '-created' }} let:items let:pages>
  {#each items as item}
    <h1>{item.title}</h1>
  {/each}
  {#each pages as pageNumber}
    <button on:click={() => setPage(pageNumber)}>{pageNumber}</button>
  {/each}
  <pre>{JSON.stringify(items, null, 2)}</pre>
  <span slot="error" let:error>{error}</span>
</List>

Need to retrieve a list of records from your PocketBase database? Check out the List component! You can easily paginate through your data just like you would with the getList function in the PocketBase JavaScript SDK.

The component defaults to displaying 50 records per page, starting at page 1, but you can customize the current page and results per page to fit your needs using the page and perPage props.

Declarative Pagination

You can even break the List down even further using the Pagination helper to cut down on the { #each } blocks within your markup. Simply pass your items array into the items. The component will loop over any items in the array, and expose the individual item data via the let:item directive.

You can also pass content to the pages slot provided that you also include a pages array to the pages prop. This is helpful if you want to have a list of pagination buttons. The pages slot is optional, since you may want to provide your own pagination navigation.

<script lang="ts">
  import List from '$lib/List.svelte';
  import Pagination from '$lib/Pagination.svelte';

  let page = 1;

  function setPage(number: number) {
    page = number;
  }
</script>

<List collection="posts" {page} perPage={2} query={{ sort: '-created' }} let:items let:pages>
  <Pagination {items} {pages} let:item>
    <h1>{item.title}</h1>
    <button slot="pages" let:pageNumber on:click={() => setPage(pageNumber)}>{pageNumber}</button>
  </Pagination>
  <span slot="error" let:error>{error}</span>
</List>

Full List

<script>
  import { FullList } from 'svelte-pocketbase';
</script>

<FullList collection="posts" batch={50} let:records>
  {#each records as record}
    <p>{record.title}</p>
  {/each}
  <span slot="error" let:error>{error}</span>
</FullList>

If you want to retrieve all records from a collection as you would using the getFullList function, you can use the FullList component.

By default, the component will return a batch of 100 records, but you are free to increase or decrease this to fit your specific needs.

First Item Within a List

<script>
  import { FirstListItem } from 'svelte-pocketbase';
</script>

<FirstListItem
  collection="posts"
  filter={'slug="my-post"'}
  let:record>
    <h1>{record.title}</h1>
    <span slot="error" let:error>{error}</span>
</FirstListItem>

If you are looking to find that one specific record that matches a certain parameter, the FirstListItem component has got your back! Set the collection prop and provide a filter, and it will return the first record that fits the bill. It's like the firstListItem function, but without all the chaining.

Conditional User Rendering

<script>
  import { User } from 'svelte-pocketbase';
</script>

<User let:user>
  <div>
    <p>Name: {user?.name}</p>
    <p>Email: {user?.email}</p>
  </div>
  <div slot="signedout">
    <li><a href="/login">Log in</a></li>
    <li><a href="/register">Register</a></li>
  </div>
</User>

Need to show (or hide) certain parts of your UI based on a user's authentication status? Simply wrap any content you want to conditionally render with the User component, and it will only appear if there is a valid user object in the authStore.

If you want a fallback element for signed-out users? Just assign it to the signedout slot.

Also, if you want to render a placeholder during the loading phase, assign an element to the loading slot as we do for all other components.

To access the user's data, just use the let:user directive to pass it down to any child elements.

Protecting Specific Routes

The User component is pretty sweet, but it is not a sufficient method for protecting critical areas of your application. If you need to protect specific routes, you should consider using a hooks.server.(ts|js) alongside load functions inside your +page.server.(ts|js).

To save you the hassle of looking it up yourself, I've included a few examples below that can help get you started.

hooks.server.ts

//    src/hooks.server.ts

import { env } from '$env/dynamic/public';
import type { Handle } from '@sveltejs/kit';
import PocketBase from 'pocketbase';

export const handle: Handle = async ({ event, resolve }) => {
    event.locals.pb = new PocketBase(env.PUBLIC_POCKETBASE_URL);

    // Grab the cookie from request headers
    const cookie = event.request.headers.get('cookie');

    // load the store data from the request cookie string
    event.locals.pb.authStore.loadFromCookie(cookie || '');

    try {
        // get an up-to-date auth store state by verifying and refreshing
        // the loaded auth model (if any)
        event.locals.pb.authStore.isValid && (await event.locals.pb.collection('users').authRefresh());
    } catch (_) {
        // clear the auth store on failed refresh
        event.locals.pb.authStore.clear();
    }

    const response = await resolve(event);

    // send back the default 'pb_auth' cookie to the client with the
    // latest store state
    response.headers.set('set-cookie', event.locals.pb.authStore.exportToCookie());

    return response;
};

+page.server.ts

//    src/routes/protected-route/+page.server.ts

import { redirect } from '@sveltejs/kit';
import type { PageServerLoad } from './$types';

export const load = (({ locals }) => {
    //    check to see if the user is authenticated
    if (!locals.pb.authStore.isValid) {
        //    if not, redirect them to "/login"
        throw redirect(303, '/login');
    }
}) satisfies PageServerLoad;

Contribute

This library is still very much work-in-progress. As mentioned before, you may want to avoid using this in a production setting until things are a bit more polished. I hope to add additional features such as realtime features and CRUD helpers in the near future.

Feel free to contribute to this project if you have ideas or suggestions for improvements.
