The ticket says "let customers export their statement."

I needed to pull a few fields out of some JSON.

You're building the kind of feature where the logic can't all live in your code.

A while back I wrote about how Erlang's parser tools saved my DSMR library: the story of binning a pile of regex and letting leex and yecc read the telegrams that Dutch and Belgian smart meters spit out every second.

You search for "regex postcode Nederland" because you need the small answer.

I already wrote about why international address handling gets messy in Ruby.

I've always been the type of developer who starts with the simplest solution.

You're building an e-commerce site, and a customer from Japan reaches checkout.

You're building a React app with server-side rendering, and the client needs a little data before it can do anything useful: user preferences, API endpoints, feature flags, that sort of thing.

I've rebuilt my notes too many times.

You're building a page with a long scroll.

I've written changesets that were trying very hard to be impressive.

Fetching data in a React component looks harmless at first.

React Hooks took me a little while to get used to after they were introduced in React v16.8.0.

You're adding Stripe to a Rails app.

I've built this screen more times than I can count: a table of orders, a search field, a status filter, maybe a date range, a few tabs across the top, pagination at the bottom.

A few years ago I wrote about how I started thinking about my styles.

If you have ever tried to edit files on Linux through the terminal, you have probably run into Vim.

To capitalize a JavaScript string, you do not need another npm dependency.

React Context, introduced in React v16.3.0, lets components read values from a shared context instead of receiving everything through props.

Some interactions need to move focus into a specific part of the page and keep it there.

Search inputs have a funny way of looking finished before they touch the network.

React refs give you access to the underlying DOM element when you need a browser API directly.

Applications often need to show a person's name in more than one format: full name, first name, initials, mention handle, sorted name, and so on.

You're reviewing a pull request and everything looks normal until one small line turns up in the diff: node_modules/ public/build/ + .idea/ Harmless enough, maybe.

The last few React projects I worked on used Redux Observable heavily.

If I had received a dollar for every time I promised myself I was about to write the most maintainable CSS I had ever seen, I could have bought a lot of coffee by now.

As a web developer, you have probably run into polymorphic JavaScript, or universal JavaScript.

One useful addition to PHP's testing tools is Behat.

Before it changed its name to Passenger, the application server was called mod_rails and ran as a module inside Apache HTTPD for Ruby on Rails applications.

After I tweeted about direnv, I noticed that a lot of people were dealing with the same problem in their Node.js projects: project-specific environment variables.

Suppose you need to render something inside a Symfony template, like a toolbar.

When you write in a foreign language, you probably reach for Google Translate.

If you mostly work with PHP, Heroku may not be the first platform you reach for.

If you build Symfony applications, you will run into translations sooner or later.

Most web applications talk to at least one external service.

Today I released a small module for hiding parts of your content from everyone except specific roles, users, or organic groups.

Drush is one of those tools you want nearby when working on Drupal.

As you may have guessed from my previous post, I was using MAMP on a Mac.

When you start building Drupal themes, you quickly find a lot of default stylesheets in the page.

For a better editing experience on node forms, I installed the WYSIWYG module with the CKEditor plugin.

Most web applications need more than one environment.
