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 🙏

Fetchers

Fetchers for Lido Finance projects. Part of Lido JS SDK

Install

yarn add bido-sdk-fetch

Fetch

node-fetch package NPM, Github

import { fetch } from 'bido-sdk-fetch';

const response = await fetch('https://example.com');
const result = await response.json();

Fetch With Fallbacks

Source

A wrapper over fetch which takes an array of URLs instead of a single URL. If a request throws an exception, it takes the following URL from the array and repeats the request to it.

import { fetchWithFallbacks } from 'bido-sdk-fetch';

const urls = ['https://example.com', 'https://fallback.com'];

const response = await fetchWithFallbacks(urls);
const result = await response.json();

Fetch RPC

Source

A wrapper over fetchWithFallbacks, which is useful as a backend part of proxying RPC requests from frontend to API provider.

import { fetchRPC } from 'bido-sdk-fetch';

const options = {
  urls: [
    'http://your_rpc_server.url',
    (chainId) => `http://your_rpc_server.url/?chainId=${chainId}`,
  ],
  providers: {
    infura: 'INFURA_API_KEY',
    alchemy: 'ALCHEMY_API_KEY',
  },
};

const rpc = async (req, res) => {
  // chainId and body from request
  const chainId = Number(req.query.chainId);
  const body = JSON.stringify(req.body);

  const response = await fetchRPC(chainId, { body, ...options });
  const result = await response.json();

  res.json(result);
};

Options

Options extend RequestInit interface with the urls and providers. urls have priority over providers.

import { CHAINS } from 'bido-sdk-constants';
import { RequestInit } from 'node-fetch';

interface FetchRPCOptions extends RequestInit {
  providers?: {
    infura?: string;
    alchemy?: string;
  };
  urls?: Array<string, (chainId: CHAINS) => string>;
}

Helpers

getInfuraRPCUrl

Returns infura endpoint for API key and chainId

import { getInfuraRPCUrl } from 'bido-sdk-fetch';
import { CHAINS } from 'bido-sdk-constants';

const url = getInfuraRPCUrl(CHAINS.Mainnet, 'YOUR_API_KEY');
console.log(url); // https://mainnet.infura.io/v3/YOUR_API_KEY

getAlchemyRPCUrl

Returns alchemy endpoint for API key and chainId

import { getAlchemyRPCUrl } from 'bido-sdk-fetch';
import { CHAINS } from 'bido-sdk-constants';

const url = getAlchemyRPCUrl(CHAINS.Mainnet, 'YOUR_API_KEY');
console.log(url); // https://eth-mainnet.alchemyapi.io/v2/YOUR_API_KEY
