Web components to connect to a lightning wallet and power a website with WebLN
This project includes web components for connecting to Lightning Wallets and enabling WebLN. Websites only need to implement a single interface to connect with multiple wallets (WebLN), and users can connect from both desktop and mobile devices. These components work with pure HTML and all Javascript libraries frameworks such as React, Angular, Vue, Solid.js, etc.
npm install @getalby/bitcoin-connect-react or yarn add @getalby/bitcoin-connect-react
npm install @getalby/bitcoin-connect or yarn add @getalby/bitcoin-connect
### HTML (CDN)
You can use Bitcoin Connect without any build tools:

## 🤙 Usage
Bitcoin Connect exposes the following web components for allowing user to connect their desired Lightning wallet:
- `<bc-button/>` - launches the Bitcoin Connect Modal on click
- Optional Arguments:
- `icon-only` - display the button as an icon without "Connect wallet"
- `disabled` - mark the button as disabled
- `<bc-modal/>` - render the modal on its own
- `<bc-connector-list/>` - render the list of connectors on their own
- _more components coming soon_
Bitcoin Connect exposes the following events:
- `bc:connected` window event which fires when a wallet is connected and window.webln is ready to use
- `bc:connecting` window event which fires when a user is connecting to their wallet
- `bc:disconnected` window event which fires when user has disconnected from their wallet
- `bc:modalopened` window event which fires when Bitcoin Connect modal is opened
- `bc:modalclosed` window event which fires when Bitcoin Connect modal is closed
Current wallets supported:
- [Alby Browser extension] (https://getalby.com)
- [Alby NWC](https://nwc.getalby.com)
- [Generic NWC URL](https://github.com/nostr-protocol/nips/blob/master/47.md)
### Styling
- the following css variables can be configured as hex or rgb:

Yes! that's the main benefit.
Yes. It will use the desktop extension as the default connector if it exists.
That depends. The connection to your lightning node / wallet needs to be asynchronous so that you can use Bitcoin Connect natively on mobile websites or PWAs.
It will only work for the connectors that are shown in the modal. Some of these connectors (e.g. the Alby Browser Extension) allow to connect multiple wallets themselves. Feel free to contribute to add a new connector.
Yes. Your connection is saved to localStorage
You should have a certain level of trust on the website you decide to connect your wallet with, and that they ensure there is no malicious third-party scripts which would intend to read the wallet connection configuration, either from memory or storage. Connectors with budget controls or confirmation dialogs (Alby extension or NWC) are recommend so you have full control over your connection.
