Build complex rules, serialize them as JSON, and execute them in JavaScript

json-logic-js-jit

Another implementation of JsonLogic, which precompile JSON rules for high speed performance.

Examples

Basic

import { compile } from 'json-logic-js-jit';

const fn = compile({ "and" : [
  { ">" : [3,1] },
  { "<" : [1,3] }
]});

fn(); // true

Add operation

import { compile, addOperation } from 'json-logic-js-jit';

addOperation("plus", (a, b) => a + b);

const fn = compile({ plus: [1, 2] });

fn(); // 3

Pass data

import { compile, addOperation } from 'json-logic-js-jit';

addOperation("var", (key, data) => data[key]);

const fn = compile({ var: ["fruit"] });

fn({ fruit: "apple" }); // "apple"

Potential for Collaboration (json-logic-engine) + publish benchmark script

Hey! Nice work on the JIT Engine!

I've a similar project json-logic-engine with some similar capability. I wanted to reach out & ask if you would be interested in collaborating on the compilation mechanism.

Could you also publish the benchmark script?
