Always Bring Your Pull Requests Up to Date

Last updated on April 26, 2022 by Sal Ferrarello

A Pull Request (PR) should always be up to date with the branch into which it is being merged. Another way of saying this is you should be able to merge your PR as a fast-forward merge (even if you decide not to do a fast-forward merge). In this post we’ll look at how a safe looking PR that is out of date can be catastrophic to merge.

JavaScript Unix Timestamp from String in Time Zone

Last updated on February 27, 2022 by Sal Ferrarello

Given a string like “2022-01-01 13:00:00”, which represents a time in the “Europe/Paris” timezone, how can we get the corresponding Unix Timestamp in JavaScript? This problem is sufficiently complex that in my opinion leveraging a third-party library is the best solution.

Disable Core WordPress Update Notice

Last updated on February 7, 2022 by Sal Ferrarello

When working on projects, I often want to strictly control the version of WordPress that is running. However sometimes one of the other administrators on the site sees the “WordPress 5.9 is available! Please update now.” message and clicks it, thereby prematurely updating to a newer version of WordPress core. This notice can be disabled.

git alias tab completion for functions

Last updated on February 6, 2022 by Sal Ferrarello

When creating a Git alias that points to a function, sometimes Git provides the wrong tab completion by default (e.g. filename completion instead of branch name completion). This is how we can tell Git, which type of completion to use.

Check CORS Value from Command Line

Last updated on November 11, 2021 by Sal Ferrarello

I was checking a number of URL endpoints for CORS restrictions today and I wondered if I could check from the command line. Here are some example curl statement that get me the information I’m looking for. I think there is an opportunity for a custom function here but for now, these notes will do.

Display Keyboard Shortcut in WordPress Gutenberg

Last updated on October 15, 2021 by Sal Ferrarello

In Gutenberg (a.k.a. the WordPress Block Editor), keyboard shortcuts are displayed differently on Apple devices and other devices, e.g. ^H on an Apple device and Ctrl+H on other devices. This is accomplished with wp.keycodes.displayShortcut.

Using jq and nvm to set Node version

Last updated on March 3, 2022 by Sal Ferrarello

The nvm command allows you to switch between versions of node. Often a project will include a .nvmrc file to specify the version of node to use. Even if a project does not contain an .nvmrc file, you may be able to read the preferred node version from package.json and use that value with nvm.

ReactJS Component Limited Time Render HOC

Last updated on October 8, 2021 by Sal Ferrarello

I wanted to render a ReactJS component for a limited amount of time every time (think of a notification that pops up and then goes away). Ideally, we would like to be able to apply this limited time rendering to any component, so this was an excellent candidate for a Higher Order Component (HOC).

WordPress Filter Early Return Pattern

Last updated on August 31, 2021 by Sal Ferrarello

A common programming pattern when using WordPress filters is the early return pattern (also know as the “short-circuit” pattern). This pattern is useful when you want to allow a filter to override a value that is “expensive” to calculate.
