# LnMe - your friendly ⚡ payment page
LnMe is a personal Bitcoin Lightning payment page/widget and self-hosted [Lightning Address](https://lightningaddress.com/) server.
LnMe is a personal Bitcoin Lightning payment website and payment widget.
![demo](./lnme-demo.gif)
**See it in action: [ln.michaelbumann.com](http://ln.michaelbumann.com/) - my lightning address: bumi@ln.michaelbumann.com**
It is a small service written in Go that connects to a [lnd node](https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md) and exposes a simple HTTP JSON API to create and monitor invoices.
It comes with a configurable personal payment website and offers a JavaScript widget to integrate in existing websites.
LnMe focusses on simplicity and ease of deployment. It connects to an existing lightning node (currently LND is supported).
If [webln](https://github.com/wbobeirne/webln) is available the widget automatically use webln to request the payment;
otherwise an overlay will be shown with the payment request and a QR code.
LnMe is one [simple executable](https://github.com/bumi/lnme/releases) file that can be deployed anywhere with no dependencies. (on your own node or for example with [one click on Heroku](#heroku))
## Motivation
## Features
I wanted a simple way for people to send Lightning payments using my own lightning node.
BTCPay Server is too big and hard to run for that and I do not need most of its features.
- [x] Embeded payment page - customizable (see demo)
- [x] [Lightning Address](https://lightningaddress.com/) support
- [x] WebLN integration - if [WebLN](https://webln.dev/) is not available a QRcode and the invoice will be shown
- [x] [JavaScript widget](#javascript-widget-integration) for existing websites
- [x] [Invoice API](https://github.com/bumi/lnme/wiki/API) - simple REST API to create LN invoices from existing JS code
- [x] [LNURL-pay](https://github.com/fiatjaf/lnurl-rfc/blob/luds/06.md) support
- [x] [LNURL-pay comment](https://github.com/fiatjaf/lnurl-rfc/blob/luds/12.md) support
## Installation
LnMe connects to your [LND node](https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md), so a running LND node is required.
LnMe can easily run next to LND on the same system or any other hosting provider.
There are no other dependencies. Simply download the binary and run it!

4. `$ ./lnme`
### Running in Docker
LnMe is now available in docker too.
You can start LnMe like this: `docker run -it --rm ghcr.io/bumi/lnme:master`
A list of existing tags is available [here](https://github.com/bumi/lnme/pkgs/container/lnme).
Note: You must have [go.rice installed](https://github.com/GeertJohan/go.rice#installation)
### Configuration
@ -51,25 +41,22 @@ A list of existing tags is available [here](https://github.com/bumi/lnme/pkgs/co
To connect to the lnd node the cert, macaroon and address of the lnd node has to be configured. LnMe uses the LND defaults.
- `lnd-address`: Host and port of the LND gRPC service. default: localhost:10009
- `lnd-cert-path`: Path to the LND TLS cert file. default: ~/.lnd/tls.cert
- `lnd-macaroon-path`: Path to the LND macaroon file. default: ~/.lnd/data/chain/bitcoin/mainnet/invoice.macaroon (invoice.macaroon is recommended)
* `lnd-address`: Host and port of the LND gRPC service. default: localhost:10009
* `lnd-cert-path`: Path to the LND TLS cert file. default: ~/.lnd/tls.cert
* `lnd-macaroon-path`: Path to the LND macaroon file. default: ~/.lnd/data/chain/bitcoin/mainnet/invoice.macaroon (invoice.macaroon is recommended)
Instead of the path to the macaroon and cert files you can also provide the hex strings:
- `lnd-cert`: LND TLS cert as HEX string.
- `lnd-macaroon`: LND macaroon HEX string. (invoice.macaroon is recommended)
* `lnd-cert`: LND TLS cert as HEX string.
* `lnd-macaroon`: LND macaroon HEX string. (invoice.macaroon is recommended)
#### Other configuration
- `static-path`: Path to a folder that you want to serve with LnMe (e.g. /home/bitcoin/lnme/website). Use this if you want to customize your ⚡website. default: disabled
- `lnurlp-comment-allowed`: Allowed length of LNURL-pay comments, maximum around [~2000 characters](https://stackoverflow.com/a/417184). (default: 210)
- `disable-website`: Disable the default LnMe website. Disable the website if you only want to embed the LnMe widget on your existing website.
- `disable-cors`: Disable CORS headers. (default: false)
- `disable-ln-address`: Disable [Lightning Address](https://lightningaddress.com/) handling.
- `port`: Port to listen on. (default: 1323)
- `listen`: IP and port to listen to. Supersedes `port`. (default: :1323).
- `request-limit`: Limit the allowed requests per second. (default: 5)
* `static-path`: Path to a folder that you want to serve with LnMe (e.g. /home/bitcoin/lnme/website). Use this if you want to customize your ⚡website. default: disabled

Depending on your deployment needs LnMe can be configured using the following options:
@ -97,119 +84,30 @@ All environment variables must be prefixed by `LNME_` use `_` instead of `-`
$ LNME_LND_ADDRESS=127.0.0.1:10005 lnme
### LND Permissions
LnMe needs the following LND permissions:
### Deployment
- Read/Write permission for `invoices`
- Write permission for `address` (if you want to use the onchain option)
Use the LND [macaroon bakery](http://macaroon-bakery.freedomnode.com/) to create a new macaroon for LnMe.
To get the HEX versions of the files use `xxd -plain` e.g. `xxd -plain invoice.macaroon | tr -d '\n'`
### TOR
LnMe can connect to your lightning node through [Tor](https://www.torproject.org/). You need to have Tor installed on your system and then simply provide your LND `.onion` address (don't forget to specify the port).
## Deployment
It is the easiest to run LnMe on the same node as LND. But you can run it anywhere as long as your LND node is accessible. Simply run the binary and make sure the PORT is accessible.
If you run LNMe on a different server you will need your LND address, the LND TLS certificate (HEX) and the macaroon (HEX). (see above)
When getting the HEX of the LND files use `xxd -plain YOUR_FILE.cert | tr -d '\n'`. For example for the TLS certificate, use `xxd -plain tls.cert | tr -d '\n'`.
The TLS cert is located in the lnd directory:
- ~/umbrel/lnd/tls.cert on Umbrel
- /mnt/hdd/lnd/tls.cert on Raspiblitz
- /embassy-data/package-data/volumes/lnd/data/main/tls.cert on Start9 Embassy
- Can also be located in ~/.lnd
You should find the macaroon files in the LND data dir (e.g. ~.lnd/data/chain/bitcoin/mainnet/) or see "LND Permissions" how to create a new one.
### Heroku
It is the easiest to run LnMe on the same node as LND. But you can run it anywhere as long as your LND node is accessible.
#### Heroku
One click deployment with Heroku:
[![Deploy on Heroku](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy?template=https://github.com/bumi/lnme)
Here is a [Video Demo of the Heroku deployment](https://www.youtube.com/watch?v=hSFXhnLp_Rc)
In order to run Tor on Heroku, the Heroku deployment includes a non-official buildpack: https://github.com/iamashks/heroku-buildpack-tor-proxy
This buildpack can be disabled and removed if not needed or desired, through the Settings tab on the Heroku dashboard, or by editing app.json and removing the buildpack.
Lastly, using the Heroku deployment, you can link the app to your own domain by following the directions here: https://help.heroku.com/MTG1BIA7/how-do-i-connect-a-domain-to-my-heroku-app
### Fly.io
#### 0. Clone the repo
$ git clone https://github.com/bumi/lnme.git
$ cd lnme
#### 1. Create a new app
$ flyctl launch --generate-name // or set a custom app name: flyctl launch --name lnme-test-1
You will be asked a few things:
* Copy the configuration to the new app
* You do NOT need to create a Postgresql Database
* Do NOT deploy it directly, we first need to set some configs
#### 2. Set the configuration using environment variables:
The LND config variablse are required. Others are optional:
$ flyctl secrets set LNME_LND_ADDRESS="xxx.xxx.xxx.xxx:10009" LNME_LND_CERT=xxx LNME_LND_MACAROON=xxx
$ flyctl secrets set DISABLE_WEBSITE=1 // etc.
#### 3. Launch the app:
$ flyctl deploy
#### 4.Configure your domain
To configure a custom domain check the [fly.io guides](https://fly.io/docs/app-guides/custom-domains-with-fly/)
### Custom deployment notes
#### Notes
To run LnMe as systemd service have a look at the [systemd service example config](https://github.com/bumi/lnme/blob/master/examples/lnme.service)
I am running LnMe behind a reverse proxy using [caddy](https://caddyserver.com/) which comes with [fully-managed HTTPS](https://caddyserver.com/docs/quick-starts/https) via [letsencrypt](https://letsencrypt.org/).
Example Caddyfile:
```
lnme.michaelbumann.com {
reverse_proxy 127.0.0.1:1323
}
```
`$ caddy --config /etc/caddy/Caddyfile`
`$ caddy --config /etc/caddy/Caddyfile`
## Feature Usage
### Lightning Address
The Lightning Address is an Internet Identifier that allows anyone to send you Bitcoin over the Lightning Network.
Lightning Address builds on [LNURL-pay](https://github.com/fiatjaf/lnurl-rfc/blob/luds/06.md) LnMe handles the necessary requests for you.
For more information check out the website: [lightningaddress.com](https://lightningaddress.com/)
Your Lightning Address: `{anything}@{your domain}`
### LNURL
if you got the Lightning Address enabled you also get a LNURL-pay URL:
https://`{your domain}/lnurlp/{anything}`

To request a lightning payment simply call `request()` on a `new LnMe({value: value, memo: memo})`:
```js
var lnme = new LnMe({ value: 1000, memo: "high5" });
var lnme = new LnMe({ value: 1000, memo: 'high5' });
lnme.request();
```
Use it from a plain HTML link:
```html
<a
href="#"
onclick="javascript:new LnMe({ value: 1000, memo: 'high5' }).request();return false;"
>Tip me</a
>
<a href="#" onclick="javascript:new LnMe({ value: 1000, memo: 'high5' }).request();return false;">Tip me</a>
```
##### More advanced JS API:
```js
let lnme = new LnMe({ value: 1000, memo: "high5" });
let lnme = new LnMe({ value: 1000, memo: 'high5' });
// get a new invoice and watch for a payment
// promise resolves if the invoice is settled
lnme.requestPayment().then((invoice) => {
alert("YAY, thanks!");
lnme.requestPayment().then(invoice => {
alert('YAY, thanks!');
});
// create a new invoice
lnme.addInvoice().then((invoice) => {
console.log(invoice.PaymentRequest);
lnme.addInvoice().then(invoice => {
console.log(invoice.PaymentRequest)
});
// periodically watch if an invoice is settled
lnme.watchPayment().then((invoice) => {
alert("YAY, thanks!");
lnme.watchPayment().then(invoice => {
alert('YAY, thanks!');
});
```
## Motivation
I wanted a simple way for people to send Lightning payments using my own lightning node.
BTCPay Server is too big and hard to run for that and I do not need most of its features.
## Development
Use `go run` to run the service locally:
Use `go run` to ron the service locally:
$ go run lnme.go --address=127.0.0.1:10009 --cert=/home/bitcoin/lightning/tls.cert --macaroon=/home/bitcoin/lightning/invoice.macaroon
## Build
LnMe uses [go.rice](https://github.com/GeertJohan/go.rice) to embed assets (HTML, JS, and CSS files). run `rice embed-go` (needs to be [installed](https://github.com/GeertJohan/go.rice#installation))
$ rice embed-go
