exframe-rules

A lightweight module to handle fetching and evaluating rules

Constructor arguments:

• db object The database object
• cacheTimeout number (optional, default 60) The time in seconds to cache the rules

evaluate() arguments:

• context object The context object
• rule object The rule object
  • companyCode string
  • state string
  • product string
  • code string
• document object The document object

Based on the 'condition' of the fetch rule, returns either the default 'onTrue' or 'onFalse' output value. See the test/index.test.js file for examples.

Example usage:

import { Rules } from 'exframe-rules';
const rules = new Rules(db);

const { companyCode, state, product } = document.csp;
const result = await rules.evaluate(
    context,
    {
        companyCode,
        state,
        product,
        code: shortRated
    },
    document
);
