This repo has 3 packages: Node Package Package for browsers Package to implement with Salesoforce - Lightning Web Component framework (LWC)
You'd find a working example for RuleParser in the example module with each package, here's the description. Refer main.js/RuleParser js modules which are at the core of this library.
for node
const formulaParser = require("./index.js");
for lwc:
import { loadParserDependencies, formulaParser} from 'c/ruleParser'
ruleJSON = formulaParser.parse(userInput); //throws error if logic is incorrect
-use parantheses for logic separation for '&&' and '||' operators
