Instructions

Architecture dependencies

1. Node >=8.12.0
2. NPM
3. Postgres >=10.5 # https://www.postgresql.org/download/linux/ubuntu/
4. LND >=0.5 #https://github.com/lightningnetwork/lnd

DB Setup

1. Create a system user, e.g. lnpoker
2. Create a postgres role with the same username, e.g. lnpoker

sudo adduser lnpoker # go through prompts for password etc.

su - postgres # switch to postgres user

createuser --interactive # role name should be same as system user created above

3. Create a database with the same name

psql # enter psql command line

create database lnpoker; # dbname should be same as role name and system user created earlier

4. Switch to newly created system user and create test DB

su - lnpoker

psql # enter psql command line

create database lnpokertest;

5. Download file in the repo named "lnpokerschema.sql" and move it to the home folder of our user

cd \home\lnpoker

https://raw.githubusercontent.com/tonyea/lnpoker/master/lnpokerschema.sql

6. Import DB schema into the two DBs.

psql -U lnpoker lnpoker < lnpokerschema.sql # as system user lnpoker
psql -U lnpoker lnpokertest < lnpokertestschema.sql # as system user lnpoker

Repo Setup

1. Clone repo and install dependencies

git clone https://github.com/tonyea/lnpoker.git

npm install

npm run client-install # package.json command that installs dependencies in client folder

2. Create a .env file in root folder of repo and input connection credentials for your lightning node. See https://dev.lightning.community/guides/installation/

PORT=5000
SOCKET_PORT=8010
jwtSecretOrKey=createownkeyhere
PGHOST=localhost
PGUSER=lnpoker
PGDATABASE=lnpoker
PGTESTDATABASE=lnpokertest
PGPASSWORD=passwordcreatedearlier
PGPORT=5432 # in psql as lnpoker, check /conninfo to find port if unsure
LNPOKER_MACAROON=/location/of/admin.macaroon
LNPOKER_TLS=/home/.lnd/tls.cert # this is the default, change as per your lightning settings
LNPOKER_HOST=localhost:10001 # depends on which port your node is running
GRPC_SSL_CIPHER_SUITES=HIGH+ECDSA
NODEURI=03e61c6a47778c4521d96b059bd782b15eb3d8c165306587ceae08014119bbc4cc@localhost:10011 # use own node uri. Get by running command lncli getinfo on node

3. Run tests and check if DB connection worked

npm run test

4. Serve file
5. Visit localhost, create at least two profiles, create a game as profile 1 and join game as profile 2 (separate browser or anonymous browsing) to play.

lnpoker's Issues

Install issue: JwtStrategy requires a secret or key

Hi,
I get the following error message when I run node app.js:

D:\wamp64\www\vamppoker\node-poker\node_modules\passport-jwt\lib\strategy.js:45
        throw new TypeError('JwtStrategy requires a secret or key');
        ^

TypeError: JwtStrategy requires a secret or key
    at new JwtStrategy (D:\wamp64\www\vamppoker\node-poker\node_modules\passport-jwt\lib\strategy.js:45:15)
    at module.exports.passport (D:\wamp64\www\vamppoker\node-poker\passport.js:15:5)
    at Object.<anonymous> (D:\wamp64\www\vamppoker\node-poker\app.js:34:22)

How does the .env file look like or how can I solve this issue?

I installed everything with npm install, but what should I do then? A lot has changed since you did the fork :)

regards

Can I contribute?

Hi,
glad that I found this repo. Can I contribute to this repo?
Would be fun and I am willing to contribute to the UI on the game table.
