For today's hackday I am going to try and start to build an access controlled "route" in solid-server, which grants access to a resource based on a credit system. If you have credits, it will show you the resource. If not you will get a 402. This builds a bit more functionality on the code written for the previous hack day. I'll try and incorporate the work from the web payments WG


The demo contains 4 components

  • /pay -- the resource that costs 25 credits to view
  • /balance -- shows your balance
  • /faucet -- a small app that will see your balance
  • /home -- navigation and instructions

Each was deployed as a custom route with its own handler.


Installation is via

git clone

Then run

npm install
$ bin/server.js  --port 8443 --ssl-key path/to/ssl-key.pem --ssl-cert path/to/ssl-cert.pem
# server running on https://localhost:8443/
How do I get the --ssl-key and the --ssl-cert?

You need an SSL certificate you get this from your domain provider or for free from Let's Encrypt!.

If you don't have one yet, or you just want to test solid, generate a certificate

$ openssl genrsa 2048 > ../localhost.key
$ openssl req -new -x509 -nodes -sha256 -days 3650 -key ../localhost.key -subj '/CN=*.localhost' > ../localhost.cert


Using webcredits it is possible to set up a faucet using

credit create

credit genesis

credit insert 50000 ''
