All is explained in the writeup

Dev setup

Frontend

Requires node.js and I'm using pnpm as well but should work just fine with npm.

• cd into the frontend folder
• pnpm install
• pnpm run dev
• visit http://localhost:3000

Backend

Replace the macaroon/tls/url with the right values for you

cd backend
go get ./...
go run *.go serve --lnd.macaroon /Users/a/.polar/networks/1/volumes/lnd/dave/data/chain/bitcoin/regtest/admin.macaroon --lnd.tls /Users/a/.polar/networks/1/volumes/lnd/dave/tls.cert --lnd.url 127.0.0.1:10004

Subscriber

An initial subscriber process has been created to do the pull-based subscription payments once the macaroon has been created by the payer.

Running:

Pass it a macaroonHex that has been created with the above bakery API, and the subscriber pubkey where the payment should go. Make sure accept-keysend is running on the receiving node.
