After cloning a repository for an Electron React Boilerplate on GitHub, I came across this code snippet in the main.js file:
if ( process.defaultApp || /[\\/]electron-prebuilt[\\/]/.test(process.execPath)I understand that this is regex, but I'm unclear on its purpose and what it does. What is the significance of /[\\/] in this context?
This usage is unfamiliar to me, and I don't even know what keyword to use for searching on Google since I lack a reference point.
It is performing a test to determine its current environment. By checking if any of the regex patterns match with process.defaultApp or evaluate to true, the code can identify whether it is in a development or production environment. This distinction is useful for running specific code in development, such as logging details or debug messages, without affecting the production environment. An example of how this is implemented can be found here, where dev tools are only enabled during development.
The code specifically uses the regular expression /[\\/] to check if the path references electron-prebuilt. The brackets `[]` match any character within them, accounting for variations in file paths based on different operating systems. For instance, Windows paths may use backslashes `\`, so the presence of `\\` indicates an escape sequence for a backslash.
For example, C:/users/blah/someOtherFolder/electron-prebuilt/etc/etc
If the code is being executed from a path that includes electron-prebuilt, it suggests that it is not a deployed production application.
