Using Playwright CLI with System Chromium on Omarchy

A quick guide to configuring Playwright CLI to use your system-installed Chromium browser instead of downloading its own, plus enabling skills for both OpenCode and Claude Code.

Stripe CreatePaymentIntent: Amount and Fee Handling

Your Observations Are Partially Correct

Amount Parameter (Decimal)

✅ Correct: The amount parameter comes in as a decimal (e.g., 10.00) and gets converted to cents internally:

Customer Pays Fees: Historical Bug Fixes and Issues

This document contains historical information about bugs discovered and fixed during the implementation of the Customer Pays Fees feature. This is preserved for reference but is not part of the current operational documentation.

Timeline

April 2025: Initial Implementation

• Only updated Payments::CalculateFee with fee rates per payable type
• Stripe::CreatePaymentIntent and Payments::Create still hardcoded booking_fee
• Root cause of subsequent bugs: Multiple fee calculation points with inconsistent rates

In this small guide I will share the setup I use to contribute to SpreeCommerce.

Disclaimer: This post contains some content written by me and others for the developer guides at SpreeCommerce.

Fork and setup upstream remote

Fork the repo the spree repository on github and clone the spree project on your local machine:

git clone YOUR-REPO-URL

peterberkenbosch

set = [1.1, 1.2, 0.85, 2.0, 1.3, 3.2]
geo_avg = (set.inject{|a,b| a*b}) ** (1.0/set.size)

peterberkenbosch

Spree.config do |config|
  config.send_core_emails = false
end

peterberkenbosch

config.payload_builder = {
  #... rest omitted for clearity.
  "Spree::Order" => { serializer: "Spree::Wombat::OrderSerializer", root: "orders", filter: "complete" }
}
