Here is the situation you might have.
You work on a WordPress theme and use SASS to create your files. Here is an example structure of your theme:
my-theme/ scss/ style.scss style.css style.css.map ...
To watch your SASS changes and generate your CSS, you usually run the terminal command like this one.
$ sass --watch style.scss style.css
This command will listen to all changes you make inside your SCSS generate and save the CSS file.
Important: Your CSS file must be opened inside the Sublime Text 3 for this method to work. If you close it, you lose the monitor. To assure you have it always opened, you may use another Sublime package called Lock Tab.
However, the SFTP package won’t upload the dynamically created CSS file by default, and you need to do this manually by creating a monitor.
See the screenshot below to apply this to your style.css file. All files with monitor will have the SFTP: Monitoring displaying in the bottom toolbar. In reality, you can monitor any dynamically generated file this way.
You can open the SFTP output console to see the result, and it will be something like this:
Uploading "/path/to/local/folder/sass/style.scss" to "/public/wp-content/themes/my-theme/sass/style.scss Uploading "/path/to/local/folder/style.css" to "/public/wp-content/themes/my-theme/style.css
I hope this will help you improve your workflow and save you some time.
