Setup

The project inherits code from a base repository.

The base / root project is: https://github.com/bitfinexcom/bfx-util-js

Setup

Set upstream

git remote add upstream https://github.com/bitfinexcom/bfx-util-js

Changes should go through the base project and merged from upstream, if applicable.

Configuration

bash setup-config.sh

Grapes

Run two Grapes:

grape --dp 20001 --aph 30001 --bn '127.0.0.1:20002'
grape --dp 20002 --aph 40001 --bn '127.0.0.1:20001'

Update Geo/ASN data

First, export your license key, for staging/prod we have a comercial license. For dev, you can get a free key key optained through https://dev.maxmind.com/geoip/geolite2-free-geolocation-data?lang=en

export MAXMIND_LICENSE='your secret license'

npm run update-geo-data
npm run update-asn-data

Periodic Updates for Geo/ASN data

Update geo-data at midnight every three days with cron. Update geo-data at 23:00 every three days with cron.

Let's assume the path to the deployed service is /opt/var/bfx-util-net.

0 0 */3 * * cd /opt/var/bfx-util-net && /usr/bin/npm run update-geo-data
0 23 */3 * * cd /opt/var/bfx-util-net && /usr/bin/npm run update-asn-data

The IP databases are watching the database files for changes and will load the updated data into the RAM as soon as the data changes.

Boot worker

node worker.js --env=development --wtype=wrk-util-net-api --apiPort 8721

SSL / ACL

To turn on ACL and SSL set up, copy sec-test to sec:

cp -R sec-test sec

Set access rules in sec/acl.json

Access is logged to sec/acl.log.

To use SSL in example.js, uncomment everything related to SSL: https://github.com/bitfinexcom/bfx-util-net-js/blob/8d07c144f3a4135db0d4c7bc51297ffc06e358f9/example.js#L16.L24
