@pevey/medusa

Extended Medusa JS SDK with support for custom plugins. Drop-in replacement for @medusajs/js-sdk that adds typed methods for Reviews, Content, Forms, and Analytics alongside all core Medusa functionality.

Installation

yarn add @pevey/medusa

Setup

import Medusa from '@pevey/medusa'

const sdk = new Medusa({
  baseUrl: 'http://localhost:9000',
  publishableKey: 'pk_...',
  auth: {
    type: 'session'
  }
})

All configuration options from @medusajs/js-sdk are supported, plus:

Option	Type	Description
analytics.salesChannelId	string	Default sales channel ID for analytics events
analytics.cartId	string	Default actor ID (typically cart ID)
analytics.batchSize	number	Flush when batch reaches this size (default: 10)
analytics.flushInterval	number	Flush interval in ms (default: 2000)

Store

All core store methods from @medusajs/js-sdk are available unchanged:

const regions = await sdk.store.region.list()
const cart = await sdk.store.cart.create({})
const products = await sdk.store.product.list()

Reviews

// List approved reviews for a product
const { reviews, count } = await sdk.store.review.list('prod_123')

// Submit a review (requires customer authentication)
const { review } = await sdk.store.review.create('prod_123', {
  rating: 5,
  body: 'Excellent quality',
  author_name: 'Alice',
  author_email: '[email protected]'
})

Content

// List content collections
const { content_collections } = await sdk.store.content.list()

// Get a specific collection
const { content_collection } = await sdk.store.content.retrieve('blog')

// List published items in a collection
const { content_items } = await sdk.store.content.listItems('blog', {
  tag: 'announcements',
  limit: 10
})

// Get a specific content item
const { content_item } = await sdk.store.content.retrieveItem('blog', 'hello-world')

Forms

// Submit a form
const { submitted } = await sdk.store.form.submit('contact', {
  data: {
    name: 'Alice',
    email: '[email protected]',
    message: 'Hello!'
  },
  cf_turnstile_response: 'token...'  // optional, if Turnstile is enabled
})

Products (Expanded Types)

sdk.store.product.list() and sdk.store.product.retrieve() return an expanded StoreProduct type that includes review data when the reviews plugin is installed:

const { products } = await sdk.store.product.list()

// products[0].reviews       — Review[]
// products[0].review_stats  — { average_rating: number, count: number }

Admin

All core admin methods from @medusajs/js-sdk are available unchanged:

const { orders } = await sdk.admin.order.list()
const { products } = await sdk.admin.product.list()

Reviews

// List reviews with filtering
const { reviews } = await sdk.admin.review.list({
  status: 'pending',
  product_id: 'prod_123'
})

// Get a single review
const { review } = await sdk.admin.review.retrieve('rev_123')

// Update a review
await sdk.admin.review.update('rev_123', { status: 'approved' })

// Delete a review
await sdk.admin.review.delete('rev_123')

// Bulk approve/reject
await sdk.admin.review.approve(['rev_123', 'rev_456'])
await sdk.admin.review.reject(['rev_789'])

Analytics

Privacy-focused event tracking with automatic batching. Events are sent to the Mildred analytics endpoint at /store/ping.

// Track an event
sdk.analytics.track('product_viewed', {
  properties: { product_id: 'prod_123' }
})

// Identify a customer
sdk.analytics.identify('cust_123', {
  anonymous_id: 'cart_abc'
})

// Set default actor/sales channel
sdk.analytics.setCartId('cart_abc')
sdk.analytics.setSalesChannelId('sc_123')

// Force flush queued events
await sdk.analytics.flush()

// Cleanup (flushes and stops timer)
await sdk.analytics.destroy()

Browser behavior: Events are queued and flushed in batches (default: 10 events or every 2 seconds). On page unload, remaining events are sent via navigator.sendBeacon for reliability.

Server behavior: Events are sent immediately with no batching.

Authentication

Authentication works exactly like @medusajs/js-sdk:

// Customer login
await sdk.auth.login('customer', 'emailpass', {
  email: '[email protected]',
  password: 'password'
})

// Customer registration
await sdk.auth.register('customer', 'emailpass', {
  email: '[email protected]',
  password: 'password'
})

// Logout
await sdk.auth.logout()

Raw Client

For endpoints not covered by the SDK, use sdk.client.fetch():

const result = await sdk.client.fetch('/admin/custom-endpoint', {
  method: 'POST',
  body: { key: 'value' }
})

Types

All types are exported for use in your application:

import type {
  // Custom plugin types
  Review,
  StoreCreateReviewInput,
  ContentCollection,
  ContentItem,
  FormSubmitInput,
  TrackOptions,

  // Expanded core types
  StoreProduct,
  AdminProduct,

  // SDK config types
  MedusaConfig,
  Config,
  ClientHeaders,
