lapswim's Introduction

Lapswim

Today's lap swim schedule at Baltimore's Waverly and Towson Ys in the terminal.

Schedules are scraped with Playwright, logged to stdout, and cached in a local json file for the day. The app is ran automatically by launchd on login and every 5 minutes.

Assumptions

macOS
jq installed via Homebrew at /opt/homebrew/bin/jq
Node.js installed via nvm at ~/.nvm
lapswim installed at ~/Code

Usage

Clone lapswim
Install dependencies

npm i

Copy the sample plist file to your user agent directory and rename it

cp ./src/local.lapswim.plist.sample ~/Library/LaunchAgents/local.lapswim.plist

Edit the Program and StandardErrorPath key values in ~/Library/LaunchAgents/local.lapswim.plist so the paths correspond to your machine
Load the plist file with launchd

launchctl load ~/Library/LaunchAgents/local.lapswim.plist

Set an alias in your terminal config file

# .zshrc, .bashrc, etc
alias swim='node ~/Code/lapswim/src/lapswim.mjs'

Open a new terminal and run the swim alias to get today's lap swim times!

lapswim's Issues

Run app on machine startup for preemptive data update

Cache today's data on first run for subsequent runs throughout the day

Handle alerts for possible closures

All Ys are closed today for some event, yet the schedule that this app scrapes doesn't reflect this. As a result the output from this app shows that there are three lap swim times today.

Check for alerts when scraping data and include any in the logged output.

Alerts are represented in a XHR response:
