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 🙏

Readme

rdkit-provider

Initialises a web worker with RDKitModule instance from @rdkit/rdkit and exposes it via a react context

Setup

Assets

The project using this package needs to provide it with RDKit package assets

After installing @rdkit/rdkit copy to your public folder node_modules/@iktos-oss/rdkit-provider/lib/rdkit-worker*.js node_modules/@rdkit/rdkit/dist/RDKit_minimal.js node_modules/@rdkit/rdkit/dist/RDKit_minimal.wasm

Usage

Wrap your components/App with RDKitProvider

import { RDKitProvider } from '@iktos/rdkit-provider';
<RDKitProvider>
  <Component />
</RDKitProvider>

you can also enable caching for molecule, which would enhance performance

import { RDKitProvider } from '@iktos/rdkit-provider';
<RDKitProvider cache={{ enableJsMolCaching: true, maxJsMolsCached: 50 }}>
  <Component />
</RDKitProvider>

Options that can be passed to RDKitProvider :

| prop | type | functionality | required/optional | | ----------------------- | ----------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ----------------- | | cache | RDKitProviderCacheOptions = { enableJsMolCaching?: boolean; maxJsMolsCached?: number; } | enables JSMol caching for better performance | optional | | preferCoordgen | boolean | will be passed to @rdkit/rdkitjs prefer_coordgen to use Schrodinger’s open-source Coordgen library to generate 2D coordinates of molecules | optional | | removeHs | boolean | toggles removing hydrogens molecules. Defaults to true | optional | | initialWorkerInstance | Worker instance of rdkit-worker.js | pass an rdkit worker instance, if not passed rdkit-provider creates one for you | optional | | rdkitPath | string default to /RDKit_minimal.js in initRDKit.ts | pass a custom path to rdkit module | optional | | rdkitWorkerPublicFolder | string, default is '', meaning the file is at the root level of the public folder | path to the folder containing the rdkit-worker-[version].js relative to the public folder | optional |

You can make use of a set of helper functions exposed by the package

import { useRDKitUtils, useRDKit } from '@iktos/rdkit-provider';

const Component = () => {
  const { worker } = useRDKit();
  const { isValidSmiles } = useRDKitUtils();
  const submit = useCallback(
    async (smiles) => {
      const { isValid } = await isValidSmiles({ smiles });
      if (!isValid) return;
      // ...
    },
    [isValidSmiles],
  );

  if (!worker) return 'loading ...';
  return <>...</>;
  //...
};
