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.

QMK 65% Esc and Backtick

Last updated on August 24, 2021 by Sal Ferrarello

When I downsized to a 65% keyboard I knew I was giving up function keys and a number pad but what caught me off-guard was the loss of my backtick (a.k.a. grave accent(`)) key. Because my keyboard runs QMK firmware, I’ve tried a number of modifications.

QMK Drop Alt

Last updated on August 14, 2021 by Sal Ferrarello

I replaced my keyboard of many years with a Drop.com Alt keyboard. This keyboard uses QMK firmware, which allows you to create modified firmware and run it on your keyboard. These are my notes about how I built a copy of the firmware locally and pushed it to my keyboard.

Manually Trigger WordPress Heartbeat from Browser

Last updated on August 2, 2021 by Sal Ferrarello

When developing code related to the WordPress heartbeat, it is frustrating to make your code changes and then wait for the next heartbeat to occur. You can trigger the WordPress heartbeat in the browser manually to eliminate this delay.

What are PHP Namespaces?

Last updated on January 28, 2023 by Sal Ferrarello

When two functions (or classes) have the same name, it triggers a fatal error in PHP. Namespaces are used to avoid these naming collisions.

Remove newline at end of text file

Last updated on February 10, 2022 by Sal Ferrarello

Sometimes when I’m working with files in Git, I find myself with a change in a file that says “No newline at end of file”. This occurs when my editor adds the missing newline at the end of the file. While you should have a newline at the end of the file, you may have a reason for not wanting to add this change. In that case, you can remove the newline from the end of the file.

SemVer TLDR

Last updated on April 23, 2023 by Sal Ferrarello

Semantic versioning (SemVer) is a standard for defining the version numbers. A version number consists of three numbers separated by periods (X.Y.Z). The type of change being introduced (e.g. a new feature or a change that breaks backwards compatibility) determines which numbers are incremented.

What is a Git Commit?

Last updated on February 7, 2021 by Sal Ferrarello

A Git commit, represented by a single building block in my Git mental model, is a frozen moment in time for your project (sometimes referred to as a snapshot). Along with this snapshot Git stores metadata about the commit (e.g. the author of the commit). Each commit has a unique identifier called the commit hash (a.k.a. SHA), a 40 character long alphanumeric string that is often abbreviated to just the first seven characters (e.g. “2b3a38b”).
