Optimize Toolset

Iโ€™ve always been into building performant and accessible sites, but lately Iโ€™ve been taking it extremely seriously. So much so that Iโ€™ve been building a tool to help me optimize and monitor the sites that I build to make sure that Iโ€™m making an attempt to offer the best experience to those who visit them. If youโ€™re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, ๐Ÿ‘‹, Iโ€™m Ryan Hefnerย  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If youโ€™re interested in other things Iโ€™m working on, follow me on Twitter or check out the open source projects Iโ€™ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soonโ€“ish.

Open Software & Tools

This site wouldnโ€™t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you ๐Ÿ™

npm version NPM License

Installation

You can install the Rainbow Swap SDK using either npm or Yarn:

Using npm:

npm install rainbow-swap-sdk

Using Yarn:

yarn add rainbow-swap-sdk

Integrate Your dApp

Example: Swapping 1.35 TON to USDT

import {getAssetsList, getBestRoute, toNano} from 'rainbow-swap-sdk';

// 1. Load the list of available tokens
const assetsList = await getAssetsList({
    userAssets: [] // Array of asset addresses the user holds; see AssetsListParams for more details.
});

// Retrieve specific assets by their address
const inputAsset = assetsList.find(asset => asset.address === 'ton');
const outputAsset = assetsList.find(asset => asset.address === 'EQCxE6mUtQJKFnGfaROTKOt1lZbDiiX1kCixRv7Nw2Id_sDs');

// 2. Load the best swap route and swap messages
const bestRouteResponse = await getBestRoute({
    inputAssetAmount: toNano('1.35', inputAsset.decimals).toString(), // Convert 1.35 TON to nano format
    inputAssetAddress: inputAsset.address,
    outputAssetAddress: outputAsset.address,
    senderAddress: 'UQDGGjjuwhikx8ZPJsrLbKXGq7mx26D8pK_l8GqBejzB52Pa', // Optional user wallet address; if set, swap messages will be returned
    partnerId: 'demo-partner' // Optional unique identifier in our App Developer Partnership program
});

// 3. Sign and send messages to the blockchain to execute the swap.
// This example uses the React UI client. For other frameworks, refer to https://docs.ton.org/develop/dapps/ton-connect/overview
import {useTonConnectUI} from '@tonconnect/ui-react';

const [tonConnectUI] = useTonConnectUI();

const result = await tonConnectUI.sendTransaction({
    validUntil: Math.floor(Date.now() / 1000) + 60, // 60 seconds from now
    messages: bestRouteResponse.swapMessages
});

Application Status Check

You may want to check the status of your application to ensure everything is functioning correctly. For example, temporarily disable swaps if block production on TON is disrupted due to an external event like the DOGS listing.

import {getAppStatus} from 'rainbow-swap-sdk';

const {
    isSwapsEnabled, // true if everything is working fine
    message // Explanation of why swaps are disabled, if applicable
} = await getAppStatus();
