Optimize Toolset

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

About

Hi, 👋, I’m Ryan Hefner  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 you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’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 soon–ish.

Open Software & Tools

This site wouldn’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 🙏

@swapdk/wdk-protocol-bridge-swapdk-common

Shared infrastructure for the SwapDK WDK protocol bridge family. Not intended to be consumed directly — bridge-specific packages (@swapdk/wdk-protocol-bridge-swapdk-evm, -solana, …) depend on this and re-export what their users need.

What lives here

  • SwapDKClient — HTTP client for swap-engine's REST API (/quote, /swap, /track) with timeout + exponential-backoff retry.
  • Typed error hierarchy — SwapDKError, SwapDKNetworkError, SwapDKApiError (with isStaleRoute / isNotFound / isProviderUnsupported getters), SwapDKProviderError, SwapDKUserError.
  • Route selection — pickBestRoute() filters zero-quote routes and returns the highest-output one.
  • Asset utilities — toHumanDecimal, fromHumanDecimal, parseSwapKitAsset, toBigInt and the destination-side native decimals table.
  • Token registry primitives — KnownToken type, lookupToken, registerToken, plus the destination-side ERC-20 entries (USDC / USDT / WETH / WBTC / DAI / wrapped natives across the supported EVM chains).
  • HTTP types — QuoteRequest / QuoteResponse / QuoteRoute, TrackRequest / TrackResponse / TrackLeg / TrackMeta / TrackStatus, SwapRequest / SwapResponse.

What does NOT live here

  • Source-chain-specific asset mapping (e.g. EVM's NATIVE_ADDRESS = "0x000…" vs Solana's "" marker, source-chain ERC-20s/SPLs).
  • Wallet account interfaces (EvmWalletAccount, SolanaWalletAccount) — defined in their respective packages.
  • Bridge classes — SwapDKBridgeEvm, SwapDKBridgeSwapEvm, SwapDKBridgeSolana.
  • Module-specific tx-builders.

Versioning

Independent semver via changesets. Bridge-specific packages depend on this with a normal semver range; bumps here cascade through changesets the next time they're released.
