Spark: Beautiful & Functional Applications Guide

Overview

You are a web coding playground generating runnable code micro-apps ("sparks"). This guide helps you produce experiences that are not only functional but aesthetically refined and emotionally resonant.

Doing tasks

The user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. The request from the user might be an initial request (initial generation), where you are working from a brand new state in a skeleton vite project. The request could also be a followup for an existing project with lots of content.

Getting started with Python Development

Setting up your Dev Environment

Highly recommend using VSCode for developing.
Learn and always use virtual environments: venv
Highly recommend only developing on a Mac or Linux. If you are on Windows you can use Docker + VSCode to give you a Linux shell. This will reduce your likely hood of having problems install dependencies.
I really love using ptpython and ptipython because it helps with autocomplete. https://github.com/prompt-toolkit/ptpython
Real Python is definitely one of the best resources from learning Python. This is their Intro Learning Path https://realpython.com/learning-paths/python3-introduction/

Backup:

pg_dump -p 5432 database_name > database_name_data.sql

Restore backup dump into local db

psql -U username -d database_name -f objects.sql

pg_restore --verbose --clean --no-acl --no-owner -h localhost -d [db_name] db_backup.dump

React Native Guide

React Native Debugger Reactotron

Open React Native Debugger first and set the RN publishing Port to 19001. Then enabled Debug Remote JS in the Expo app.

Name Patterns for JS & React

I'm able to visually identify and understand React components. However, I do not know the names used to identify them.

Class Component:

class MyList extends React.Component {...}

Function component:

function App() {return (...)}

kill $(ps -e | grep hung_tasks | awk '{print $1}')

	#!/bin/bash

	# Set default region (you can modify this)
	AWS_REGION="us-east-1"

	# Error handling function
	error_exit() {
	echo "Error: $1" >&2
	exit 1
	}

	export $(printf "AWS_ACCESS_KEY_ID=%s AWS_SECRET_ACCESS_KEY=%s AWS_SESSION_TOKEN=%s" \
	$(aws sts assume-role \
	--role-arn arn:aws:iam::123456789012:role/MyAssumedRole \
	--role-session-name MySessionName \
	--query "Credentials.[AccessKeyId,SecretAccessKey,SessionToken]" \
	--output text))

	# Python dict.iteritems became just dict.items.
	# Easily coherse the generator into a list with: `list(gen_dict_extract("KeytoFind", MyDict))`

	def gen_dict_extract(key, var):
	if hasattr(var, 'items'):
	for k, v in var.items():
	if k == key:
	yield v
	if isinstance(v, dict):
