• Documentation: https://supabase.com/docs/reference
• TypeDoc: https://supabase.github.io/supabase-js/v2/

Usage

First of all, you need to install the library:

npm install @supabase/supabase-js

Then you're able to import the library and establish the connection with the database:

import { createClient } from '@supabase/supabase-js'

// Create a single supabase client for interacting with your database
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')

UMD

You can use plain <script>s to import supabase-js from CDNs, like:

<script src="https://cdn.jsdelivr.net/npm/@supabase/supabase-js@2"></script>

or even:

<script src="https://unpkg.com/@supabase/supabase-js@2"></script>

Then you can use it from a global supabase variable:

<script>
  const { createClient } = supabase
  const _supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')

  console.log('Supabase Instance: ', _supabase)
  // ...
</script>

ESM

You can use <script type="module"> to import supabase-js from CDNs, like:

<script type="module">
  import { createClient } from 'https://cdn.jsdelivr.net/npm/@supabase/supabase-js/+esm'
  const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')

  console.log('Supabase Instance: ', supabase)
  // ...
</script>

Deno

You can use supabase-js in the Deno runtime via JSR:

import { createClient } from 'jsr:@supabase/supabase-js@2'

Custom fetch implementation

supabase-js uses the cross-fetch library to make HTTP requests, but an alternative fetch implementation can be provided as an option. This is most useful in environments where cross-fetch is not compatible, for instance Cloudflare Workers:

import { createClient } from '@supabase/supabase-js'

// Provide a custom `fetch` implementation as an option
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key', {
  global: {
    fetch: (...args) => fetch(...args),
  },
})
