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 🙏

Polywrap React Integration

Readme

@polywrap/react

A React library that simplifies the integration of Polywrap wrappers into React applications. Instantiates the Polywrap Client, send WRAP invocations, and renders the results.

Documentation

https://docs.polywrap.io/reference/clients/js/libraries/react

Installation

npm install @polywrap/react

Usage

PolywrapProvider

Once installed, the first step is to add the PolywrapProvider to your DOM. This will instantiate an instance of the PolywrapClient for all queries within the nested DOM hierarchy to use.

To use the provider, simply wrap it around whatever DOM hierarchy you'd like to use Polywrap within:

import React from 'react';
import { PolywrapProvider } from '@polywrap/react';

export const App: React.FC = () => {
  return (
    <PolywrapProvider>
        <HelloWorld />
    </PolywrapProvider>
  );
};

PolywrapProvider Props

The PolywrapProvider component's props are the same as the PolywrapClient constructor's arguments. For example, you can configure URI redirects like so:

<PolywrapProvider redirects={ [] }/>

Multiple PolywrapProviders

If you need to use multiple providers, you can do so using the createPolywrapProvider("...") method, which accepts the name of your provider as an argument. For example:

import { createPolywrapProvider } from '@polywrap/react';

const CustomPolywrapProvider = createPolywrapProvider('custom');

export const CustomProvider = ({ children }: { children: JSX.Element }) => {
  return (
    <CustomPolywrapProvider>
      {children}
    </CustomPolywrapProvider>
  );
};

usePolywrapClient

You can obtain a copy of the client instance from your PolywrapProvider using the usePolywrapClient hook.

const client = usePolywrapClient();

usePolywrapInvoke

After enabling your React application with the PolywrapProvider, you may now use the usePolywrapInvoke hook to call into wrappers!

const { execute, data, error, loading } = usePolywrapInvoke({
  uri: 'ens/helloworld.polytest.eth',
  method: "logMessage",
  args: {
    message: "Hello World!",
  },
});

By default, the usePolywrapInvoke hook uses the first PolywrapProvider found in the DOM's hierarchy. If you'd like to specify a specific provider to be used, simply set the provider: property:

const { execute, data, error, loading } = usePolywrapInvoke({
  provider: "custom",
  uri: 'ens/helloworld.polytest.eth',
  method: "logMessage",
  args: {
    message: "Hello World!",
  },
});
