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.

Redemeum Frontend Blockchain Service

Installation

npm install redeemeum-blockchain-service --save

Prerequisites

You have to have Metamask extension installed on your browser in order this package to work properly.

Description

In order to interact with the Blockchain you would need to set the contract addresses in your .env file in the following manner:

TOKEN_CONTRACT=0x...
VOUCHER_KERNEL_CONTRACT=0x...
CASHIER_CONTRACT=0x...

Here are all the functions the Service currently provides and some useful information:

async getSigner() returns JsonRpcSigner
async getUserAddress() -> returns current logged user eth address
async signMessage(signer, nonce) -> returns signature which later will be used by the API service to authenticate the user
async requestCreateOrder(contractArgs: Array, value) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
async commitToBuy(contractArgs: Array, value) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
async refund(voucherID) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
async complain(voucherID) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
async cancelOrFault(voucherID) -> Broadcast tx to the blockchain. Returns parsed event from the BC transaction
