> [!NOTE]
> Do you want to help us shape the future of this library? [We're hiring](https://jobs.ashbyhq.com/supabase/85d07345-47c6-4980-82e2-57782f83ab4e).
## Usage
First of all, you need to install the library:
```sh
npm install @supabase/supabase-js
```
Then you're able to import the library and establish the connection with the database:
```js
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 ``s to import supabase-js from CDNs, like:
```html
<script src="https://cdn.jsdelivr.net/npm/@supabase/supabase-js@2">
```
or even:
```html
```
Then you can use it from a global `supabase` variable:
```html
const { createClient } = supabase
const _supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')
console.log('Supabase Instance: ', _supabase)
// ...
```
### ESM
You can use `` to import supabase-js from CDNs, like:
```html
<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)
// ...
```
### Deno
You can use supabase-js in the Deno runtime via [JSR](https://jsr.io/@supabase/supabase-js):
```js
import { createClient } from 'jsr:@supabase/supabase-js@2'
```
### Custom `fetch` implementation
`supabase-js` uses the [`cross-fetch`](https://www.npmjs.com/package/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:
```js
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),
},
})
```
