QueryCurve

This tool allows you to invoke queries against a curve you've laid out at https://querycurve.com

Once you have a curve in the shape you'd like:

You'll get a resulting encoded curve that'll look like this: 2BLnMW-2BLnMW--KyjA--KyjA-0-KyjA-CaR6-XZAG-KyjA-TN1E-KyjA-KyjA-KyjA-CaR6-TN1E-8OI4-fxSK-KyjA

Time to query!

Installation from npm

$ npm install --save @query-curve/query

Usage

import { getEncodedCurveQueryFunction, queryEncodedCurve } from '@query-curve/query';

queryEncodedCurve('5SNUPI-8nlt2n2-0-0-0-fxSK-3yGp-fn3A-TzAp-e6zY-bau8-PAsC-dGxk-LXPh-f3xT-9cbF-fxSK-0', 0);

Querying with a dynamically loaded curve

If you are pulling your curve from a db or otherwise need it to be dynamic:

const dynamicallyLoadedCurve = 'fxSK-fxSK-0-0-0-0-KyjA-0-KyjA-fxSK-fxSK-fxSK'; // assume this was loaded from db
const myXValue = 0.35;

// Gets the corresponding y value along the curve for a given x
const result = queryEncodedCurve(dynamicallyLoadedCurve, myXValue);

Note: While decoding the curve is fast, repeatedly querying against the same curve can be optimized by preloading the curve. If you anticipate multiple queries against the same curve, consider using:

Querying with a preloaded or reused curve

If the curve you're using will be used to facilitate multiple queries, this alternative for querying will bypass the need to decode the curve on every query.

import { getEncodedCurveQueryFunction } from '@query-curve/query';
const fixedCurve = 'fxSK-fxSK-0-0-0-0-KyjA-0-KyjA-fxSK-fxSK-fxSK';
// Returns a function with a reference to the decoded curve
const queryMyCurve = getEncodedCurveQueryFunction(fixed_curve) ;

queryMyCurve(0);
queryMyCurve(0.5);
queryMyCurve(0.37);
