Liza Data Collection Framework

Liza

Liza is a data collection, validation, and processing framework for JavaScript.

About

The Liza Data Collection Framework—"Liza" for short—is an effort to clean up, formalize, and expand upon a framework that was developed at RT Specialty / LoVullo for collecting, validating, and processing large amounts of user input for insurance quoting.

Configuring

If your distribution does not contain a `configure' file in the project root, then you likely have the sources as committed to the project repository; you may generate the script by issuing the following command:

  ./autogen.sh

You may then see ./configure --help for more information.

Building

If configure is not available, see the section "Configuring" above.

First time setup:

  ./bootstrap

Subsequent builds:

  make

Additional Make Targets

  make format   # run auto-format with prettier
  make fix      # attempt to auto-fix linting errors

Delta Processor

See DELTA-PROCESSOR-README.md for more information on the delta processor daemon.

Dullahan

See DULLAHAN-README.md for more information on the Dullahan daemon.

Documentation

Compiled documentation for the latest release is available via our GitLab mirror, which uses the same build pipeline as we do on our internal GitLab instance. Available formats are:

• Multi-page HTML
• PDF
• Info

Hacking

Local Development Setup with the Connector

To be able to develop out of ~/gitrepos/rating-fw and ~/gitrepos/liza, you must use symlinks in the Connector repository:

# Ensure that liza is built properly

# create symlinks in ~/gitrepos/connector/node_modules
$ cd node_modules
$ rm -rf rating-fw
$ rm -rf liza
$ ln -s ~/gitrepos/rating-fw rating-fw
$ ln -s ~/gitrepos/liza liza

In quote-server file in Connector repo add this line

NODE_SERVER="$(pwd)/node_modules/liza/bin/server"

You should now be able to continue running the Quote Server as before while developing out of ~/gitrepos/.

Blacklisting Keys

Should a Key Encryption Key (KEK) be leaked, it must be blacklisted to prevent it from being used to encrypt additional information.

To do this, a configuration file, located in rating-fw, must be updated with the offending key. Note that blacklisted keys can still be used for decryption to allow for key rotation.

e.g.

"blacklistedKeks": [
  "leaked_kek:1"
]

Where leaked_kek is the name of the secret in Secret Manager and 1 is the version number.

NB: There are multiple environments in this directory; make sure you update the correct environment corresponding to the leaked KEK.
