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 🙏

paypal-utils

A utility library that helps you when using the PayPal node.js API. This library also helps you calculate the payment (credit-card charge) and payout fees, which can be useful if you want to charge the fees to the sender. Currently, there is no method to derive the fees directly from the PayPal API. This library uses the PayPal official fee structure documented at https://www.paypal.com/us/webapps/mpp/merchant-fees for its calculations. This is particularly useful in marketplace type transactions.

API

getCreditCardType(cardNumber: string) : string

Identifies credit card types and returns the PayPal identifier for it. This is useful when processing credit-card charges. Supported card types include visa, mastercard, discover and maestro as specified here: https://developer.paypal.com/docs/api/vault/

getPaymentFee(amount: number, currency: string): number

Returns the amount to be charged if you want to include the credit-card processing charges for a payment. Currently 2.9%

getPayoutFee(amount: number, currency: string): number

Returns the PayPal processing charges for a payout. Currently, only the flat fee is supported. Refer section PayPal Payouts and Mass Pay Fees here: https://www.paypal.com/us/webapps/mpp/merchant-fee

getTotalFee(amount: number, currency: string): number

Returns the total PayPal fee inclusive of both the payment and payout fee. Charge the sender with this amount in the recipient's currency if you don't want the receiver to pay processing fees. Reference: https://www.paypal.com/us/webapps/mpp/merchant-fees

formatAsString(amount: number, currency: string): string

Formats an amount in a particular currency to its PayPal API compatible string representation with appropriate rounding for use in APIs: https://developer.paypal.com/docs/classic/api/currency_codes/
