Examples of JavaScript SDK Usage

The PocketBase JavaScript SDK is user-friendly, facilitating rapid development for web and mobile applications. Below are some usage examples that highlight the SDK’s capabilities.

Note: PocketBase also offers a Dart SDK for additional integration options.

Real-time Database Operations

Utilize the JavaScript SDK to manage your real-time database. Key methods include getList(), getOne(), delete(), create(), and subscribe().

import PocketBase from 'pocketbase';

const pb = new PocketBase('http://127.0.0.1:8090');

// List records from the 'example' collection
const list = await pb.collection('example').getList(1, 100, {
  filter: 'title != "" && created > "2022-08-01"',
  sort: '-created,title',
});

// Fetch a single record
const record = await pb.collection('example').getOne('RECORD_ID');

// Delete a record
await pb.collection('example').delete('RECORD_ID');

// Create a new record
const newRecord = await pb.collection('example').create({
  title: 'Lorem ipsum dolor sit amet',
});

// Subscribe to changes
pb.collection('example').subscribe('*', function (e) {
  console.log(e.record);
});

// Unsubscribe from changes
pb.collection('example').unsubscribe();

User Authentication Management

Manage user authentication with methods such as create(), authWithPassword(), authWithOAuth2(), requestVerification(), requestPasswordReset(), and requestEmailChange().

import PocketBase from 'pocketbase';

const pb = new PocketBase('http://127.0.0.1:8090');

// Sign up a user
await pb.collection('users').create({
  email: 'test@example.com',
  password: '123456',
  passwordConfirm: '123456',
  name: 'John Doe',
});

// Sign in a user
await pb.collection('users').authWithPassword('test@example.com', '123456');

// OAuth2 authentication
await pb.collection('users').authWithOAuth2({ provider: 'google' });

// Request email verification
await pb.collection('users').requestVerification('test@example.com');

// Request password reset
await pb.collection('users').requestPasswordReset('test@example.com');

// Change email request
await pb.collection('users').requestEmailChange('new@example.com');

File Management

Manage files easily with methods like create() and update().

import PocketBase from 'pocketbase';

const pb = new PocketBase('http://127.0.0.1:8090');

// File input reference
const fileInput = document.getElementById('fileInput');

const formData = new FormData();

// Listen to file input changes
fileInput.addEventListener('change', function () {
  for (let file of fileInput.files) {
    formData.append('yourFileField', file);
  }
});

// Set additional fields
formData.append('title', 'Hello world!');

// Create a new record and upload files
await pb.collection('example').create(formData);

// Delete files from a record
await pb.collection('example').update('RECORD_ID', {
  'yourFileField': null,
});

Extending PocketBase Functionality

Utilize the SDK to enhance PocketBase with custom functionalities through hooks and routes.

// pb_hooks/main.pb.js

// Intercept requests
onRecordAfterUpdateRequest((e) => {
  console.log(e.record.id);
});

// Intercept system emails
onMailerBeforeRecordVerificationSend((e) => {
  // Send custom email
  e.mailClient.send(...);
  return false; // Stops propagation
});

// Register custom routes
routerAdd("get", "/hello", (c) => {
  return c.string(200, "Hello!");
});

// Schedule jobs
cronAdd("hello", "*/2 * * * *", () => {
  console.log("Hello!"); // Logs "Hello!" every 2 minutes
});
