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 🙏

API

Wallet

A wallet instance is always required to start working with Wallet API. You configure RxJS subjects to handle password management between UI subscriber and Wallet API.

Creating a wallet with createWallet

    const wallet = new Wallet();
    this.wallet.onRequestPassphraseSubscriber.subscribe(async (i) => {
      this.canUnlock = true;
      this.loading = true;
      if (i.type === 'wallet') {
        this.passphraseSubject.subscribe((passphrase) =>
          this.wallet.onRequestPassphraseWallet.next({ type: 'ui', passphrase })
        );
      } else {
        this.canUnlock = false;
        this.loading = false;
      }
    });

    let { id } = await wallet.createWallet(this.password, null, mnemonic);

Unlocking using open

Now with that id, be sure to save it somewhere, you always query the Wallet API DB to open the wallet. It will ask you for your password if you configure the RxJS Subscribers as defined in the previous step.

 await this.wallet.open(id);

Wallet.generateMnemonic

Creates a new mnemonic

     const mnemonic = Wallet.generateMnemonic();
     const selectedWallet = await Wallet.createHDWallet({ mnemonic, password: '123password' });

deriveChild

Creates a new child HD Wallet

      const child1 = wallet.deriveChild(1, `m/44'/60'/0'/0`);
      const child2 = wallet.deriveChild(2, `m/44'/60'/0'/0`);
      const child3 = wallet.deriveChild(3, `m/44'/60'/0'/0`);

deriveFromPath

Creates a new child HD Wallet

      const child1 = wallet.deriveFromPath(`m/44'/60'/0'/0/1`);
      const child2 = wallet.deriveFromPath(`m/44'/60'/0'/0/2`);
      const child3 = wallet.deriveFromPath(`m/44'/60'/0'/0/3`);

getEd25519

Creates a new Ed25519 curve

    const kp = await wallet.getEd25519();

getP256

Creates a new P256/secp256r1 curve

    const kp = await wallet.getP256();

getES256k

Creates a new secp256k1 curve

    const kp = await wallet.getES256k();

    const kp = await wallet.getRSA256Standalone();

getBlsMasterKey

Creates a new BLS key pair. Returns an object.

    const kp = wallet.getBlsMasterKey();
    const deriveValidatorKey1 = await kp.deriveValidatorKeys(1);
