How to use Mapbox to convert from coordinates to address and back again

Back in January, I promised that a future post would cover how to go from a street address to latitude / longitude coordinates.  Previously, we have covered how to get the user’s street address, using navigator.geolocation and MapQuest and more recently, we covered converting addresses to latitude and longitude but that wasn’t an actual street...

How to autofill an address using mapbox

I have been poking at the Milwaukee County Trasit System (MCTS) APIs over the past few weeks.  A few years ago, I tried to write a bus app using Angular and it just didn’t work out well.  I figured that I would try it again, using what I have learned since then.  The first step...

How to calculate the sunset and sunrise times in JavaScript

Over the holidays, I created Good Morning, Milwaukee! (a Mastodon bot that posts a “Good Morning” toot every morning).  The problem is that it hasn’t been behaving correctly since shortly after I finished it.  I want to simplify it a bit, so I can make it a little less fragile.  The first component of the...

Are you still working on the State Parks app?

Yup, I am. Last year, I posted a lot about how I was building a state parks app to help with my goal of eventually visiting every park in the Wisconsin State Parks system.  The most recent post was around November, though.  Well, I am working on the app again and I am hoping to...

Three ways to create a modal dialog

Today, we are going to look at three ways to add a modal dialog to your app.  The first option just uses CSS and JavaScript (no special libraries).  The second option uses Bootstrap (a topic that I haven’t touched in a few years).  The third and final option uses Bulma.  I looked back at my...

Where art thou: Converting addresses to latitude and longitude.

Previously, we have covered how to identify where the user is, based upon navigator.geolocation and based upon their IP address (there are definitely ways to make IP-based geolocation suck less).  I figured that in today’s post, we would look at how to go from an arbitrary physical location (zip code or city name) to latitude...

How to know your user

There are times when it is very important to know as much as you can about the user of your application.  A good example is how I need to know where the user physically is in order to calculate the distance between them and the park in the state parks app.  Another example is if...

State Parks App: I made some new APIs for the app

Last week, I wrote about creating a cloudflare worker.  When I created that worker, I knew that I wanted to leverage that for the state parks app.  This week, I created three new workers: one to get the user’s location, one to get the list of parks, and one to get an individual park.  Let’s...

Playing with Vue Router

Back in July, we looked at how Vue CLI and webpack work and I figured that it was time to look at Vue Router, as a follow-up.  Vue Router is going to be pretty necessary for the state parks app, moving forward. Like I did last time, I used VueCLI and Bulma.  I also put...

New things in ECMAScript 2021: String.prototype.replaceAll()

This is going to be a pretty quick post (mainly because I am on vacation, next week).  I was skimming through what is new in ECMAScript 2021 and spotted replaceAll().  It is already supported in everything except for Internet Explorer.  Let’s take a look at a quick example. The reference is within computed properties but...
