XPRNKit:

Accelerating dApp Development for XPRNetwork

XPRNKit is a React-based library designed to streamline decentralized application (dApp) development and prototyping on the XPRNetwork blockchain. It offers a comprehensive set of tools, components, and utilities that enable developers to rapidly build, deploy, and test dApps with minimal setup. By abstracting away much of the underlying complexity of blockchain interactions, XPRNKit empowers developers to focus on core functionality and user experience.

Whether you're creating smart contracts, integrating wallets, or handling token transactions, XPRNKit simplifies common tasks and accelerates the development process. It’s perfect for both experienced blockchain developers looking to prototype quickly and newcomers who want to get up and running with XPRNetwork faster.

Key Features

• Pre-built Components: Ready-to-use UI components for common dApp functionality like wallet connections, token balances, and transaction history.
• Blockchain Integration: Simplified access to XPRNetwork’s blockchain features, reducing the need for extensive configuration.
• Developer-Friendly Hook: A simple unique hook to access objects and method to maximizing flexibility.

XPRNKit is the ideal toolkit for developers who want to build and deploy secure, scalable, and user-friendly dApps on XPRNetwork with greater efficiency.

Overview

XPRNSwapMarketsSelector is a React functional component that renders a dropdown selector for swap market providers. It uses the Select component from a UI library and populates it with market providers from the useXPRNSwap hook. The component must be wrapped in a XPRNSwapProvider in order to be fed by markets config provided through XPRNSwapProvider config.

Props

The component accepts the following props:

• children: React node (optional)
• className: string (optional)

These props are extended from React.HTMLAttributes<HTMLDivElement>.

Usage

  );
}

Functionality

1. The component uses the useXPRNSwap hook to get marketProviders.
2. It initializes services state with useState.
3. defaultServices are memoized using useMemo and set to DEFAULT_SWAP_SERVICES.
4. defaultService is memoized to find the first service marked as default or the first service in the list.
5. The component renders a Select component

Conditional Rendering

The component only renders if there is more than one market provider (marketProviders.length > 1).

Styling

The component uses classNames for conditional class application. The root div element receives the className prop if provided.

XPRNPairsSelector Component

The XPRNPairsSelector is a React component that provides a dropdown selector for available (filtered or not) trading pairs form the selected market provider. It's designed to work within the context of an XPRNSwapProvider.

Import Statement

import * as React from "react";
import classNames from "classnames";
import {useXPRNSwap} from "./xprn-swap-provider";
import {
  Select,
  SelectItem,
  SelectContent,
  SelectTrigger,
  SelectValue,
} from "../ui/select";

Props

The component accepts the following props:

• className?: string: Additional CSS classes for the root element.
• contentClassName?: string: Additional CSS classes for the dropdown content.
• itemsClassName?: string: Additional CSS classes for the dropdown items.

These props extend the standard HTMLDivElement attributes.

Functionality

1. The component uses the useXPRNSwap hook to access swap-related data and functions.
2. It displays a dropdown of available trading pairs when the loaded by the XPRNSwapProvider from the default or selected market provider.
3. Users can select a trading pair, which updates the current swap pair inside the XPRNSwapProvider.
4. The component shows loading and error states based on the XPRNSwapProvider loading status of the pair list.

Usage

<XPRNPairsSelector 
  className="custom-class"
  contentClassName="content-class"
  itemsClassName="item-class"
/>

Render Logic

• If loading of the is "idle":
  • Renders a Select component with the current pairs as options.
• If loading of the is "pending":
  • Displays "Loading Pairs".
• If loading of the is "fail":
  • Displays "Pairs shit" (consider changing this to a more appropriate error message).

Styling

The component uses classNames for conditional styling:

• Root element: Applies the className prop if provided.
• Dropdown content: Applies "bg-white" and the contentClassName prop if provided.
• Dropdown items: Applies "text-black" and the itemsClassName prop if provided.

Notes

• The component doesn't render anything if there's only one or zero market pairs available.
• The default selected value is set based on the currentSwapPair.
• Consider improving the error message for the "fail" state to be more user-friendly and informative.

toPrecision

Description

The toPrecision function adjusts a numeric value to a specified precision, with options for rounding behavior and decimal representation. It's used to format the an arbitrary price according to the token precision.

Function Signature

function toPrecision(
  value: number,
  precision: number,
  mode: 'ceil' | 'floor' | 'round' | 'none' = 'ceil',
  forceDecimal: boolean = true
): string

Parameters

• value (number): The input number to be adjusted.
• precision (number): The number of decimal places to round to.
• mode ('ceil' | 'floor' | 'round' | 'none', optional): The rounding mode to use. Defaults to 'ceil'.
  • 'ceil': Rounds up to the nearest integer.
  • 'floor': Rounds down to the nearest integer.
  • 'round': Rounds to the nearest integer.
  • 'none': Uses 'ceil' behavior (same as 'ceil').
• forceDecimal (boolean, optional): Whether to force the output to include decimal places. Defaults to true.

Returns

• (string): The adjusted value as a string, with or without forced decimal places based on the forceDecimal parameter.

Behavior

1. Multiplies the input value by 10^precision to shift the decimal point.
2. Applies the specified rounding mode to the shifted value.
3. Divides the result by 10^precision to shift the decimal point back.
4. If forceDecimal is true, returns the result with the specified number of decimal places.
5. If forceDecimal is false, returns the result as a string without forcing decimal places.

Example Usage

console.log(toPrecision(3.14159, 2)); // "3.15"
console.log(toPrecision(3.14159, 2, 'floor')); // "3.14"
console.log(toPrecision(3.14159, 2, 'round')); // "3.14"
console.log(toPrecision(3.14159, 2, 'ceil', false)); // "3.15"
console.log(toPrecision(3, 2,'none',true)); // "3.00"
console.log(toPrecision(3, 2, 'ceil', false)); // "3"

Notes

• The 'none' mode behaves the same as 'ceil' mode.
• When forceDecimal is true, the output will always have the specified number of decimal places, even if the input is an integer.
• When forceDecimal is false, the output may have fewer decimal places than specified if they are not needed (e.g., for whole numbers).
