Slack tipping bot using LN for payments
Fetch sources from the git repository:
git clone https://github.com/CryptoFR/ln-tip-slack.git
Move into the newly created directory:
Fetch the dependencies and build the application by running:
If not started automatically, run the following command to build the application:
lncli-web is now fully compatible with macaroons and encrypted wallets.
But if you want to start
lnd with wallet encryption and macaroons disabled, just add those two parameters to the command line:
lnd [...] --no-macaroons --noencryptwallet
If you want to use macaroons, you need to copy the
admin.macaroon file to the
lncli-web root directory (by default). The default path to the
admin.macaroon file can be modified in the
Generate lnd certificates compatible with NodeJS gRPC
Beware that lnd autogenerated certificates are not compatible with current NodeJS gRPC module implementation.
Lnd uses the
P-521 curve for its certificates but NodeJS gRPC module is only compatible with certificates using the
P-256 curve (link).
You need to generate your own lnd certificates using the following commands (thanks to Alex Akselrod for helping me on this):
# Enter the Lnd home directory, located by default at ~/.lnd on Linux or # /Users/[username]/Library/Application Support/Lnd/ on Mac OSX # $APPDATA/Local/Lnd on Windows. Also change '/CN=localhost/O=lnd' to '//CN=localhost\O=lnd' if you are using Git Bash. cd ~/.lnd openssl ecparam -genkey -name prime256v1 -out tls.key openssl req -new -sha256 -key tls.key -out csr.csr -subj '/CN=localhost/O=lnd' openssl req -x509 -sha256 -days 36500 -key tls.key -in csr.csr -out tls.cert rm csr.csr
Copy generated certificate file into lncli-web directory
cp tls.cert [lncli-web_directory]/lnd.cert
Start the Webserver
Available command-line arguments:
node server --help Usage: server [options] Options: -h, --help output usage information -V, --version output the version number -s, --serverport [port] web server listening port (defaults to 8280) -h, --serverhost [host] web server listening host (defaults to localhost) -l, --lndhost [host:port] RPC lnd host (defaults to localhost:10009) -t, --usetls [path] path to a directory containing key.pem and cert.pem files -u, --user [login] basic authentication login -p, --pwd [password] basic authentication password -r, --limituser [login] basic authentication login for readonly account -w, --limitpwd [password] basic authentication password for readonly account -d, --disable-macaroon set this flag if you do not want to use macaroon files for auth -f, --logfile [file path] path to file where to store the application logs -e, --loglevel [level] level of logs to display (debug, info, warn, error) -n, --lndlogfile <file path> path to lnd log file to send to browser -k, --le-email [email] lets encrypt required contact email
Open your browser at the following address: http://localhost:8280
If you want to access
lncli-web using a domain, add the
--serverhost flag like so:
node server --serverhost <yourdomain>
Open your browser at the following addres: http://yourdomain:8280
Build the container
(from inside the lncli-web folder)
docker build . -t lncli-web
Run in a Docker container
Mount your .lnd directory to the container:
docker run -v /path/to/.lnd/:/config lncli-web
The container will generate certs if necessary.
Any commandline option (see below) can be overridden by setting an appropriate environment variable.
--lndhost, or set
Running in a Docker container connecting to a remote LND instance
Copy the admin.macaroon, tls.key and tls.cert to your machine, for example in /tmp/config.
docker run accordingly:
docker run -it -e SET_LNDHOST=[IP of lightning host]:10009 -v /tmp/config:/config --net=host lncli-web
Then just browse to http://127.0.0.1:8280. Note: this still requires you to re-generate your certificates as per above.

Enabling https for remote access
You need to have a
key.pem (private key) file and a
cert.pem (certificate) file available in your path (check the --usetls command-line option).
On Linux you can create the above files using a self-signed certificate by executing the following command:
openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 36500
You might need to run this extra command to remove the password protection:
openssl rsa -in key.pem -out newkey.pem && mv newkey.pem key.pem
And the you need to add the
--usetls command-line option to point to the directory containing your two
Example command starting a password protected Lnd Web Client with readonly account enabled, running on port 443, and using https with corresponding
pem files located in the app directory:
node server -s 443 --usetls . --user manager --pwd 33H966wG --limituser lnd --limitpwd rocks
Hoping that helps.
The lightning network graph rendering functionality requires to have
graphviz installed on the server.
Contributing to the project
As of September 27th, all new code that is created or refactored should abide by the Airbnb JS Style guide. You can use automated tooling to maintain the style guide using eslint. For simplicity, I have outlined a suggested workflow:
- write your code changes. For example, you are fixing a bug in
- once you are finished your patch, run
eslint app/lightning.js. This will show you the errors in the source code
- optionally, you can also run
eslint --fix app/lightning.jsto let eslint fix errors that it can fix without human intervention
- fix the remainig style issues. You are only required to change and commit style for the code you changed (although the more, the merrier!)
- commit your clean code
