Fast css compilation thanks to PostCSS
-
PostCSS theme fallback / child theme support
-
Small (as possible) set of PostCSS base styles and settings needed to get a working development system. Hey, it looks somehow like a Magento base theme, right? ;)
-
BrowserSync - instant css injecting into browser & weinre support
-
Theme static content is watched & transferred directly into pub/static via Gulp. No need to use Magento content deploy during development.
-
Added gulp clean and deploy tasks. If there is a need,
gulp clean
will remove everything invar/cache
,var/generation
,var/view_preprocessed
&pub/static
folder (Except .htaccess, magento blank & magento luma theme) andgulp deploy
will deploy Magento static content (short ofbin/magento setup:static-content:deploy
). -

Gulpfile paths.cssSrc would be 'app/design/fronted/Trive/theme-name' and paths.cssDest: 'pub/static/frontend/Trive/theme-name/'. Child theme will need to have styles.css and settings.css inside the same folder structure like Strive (web/src/preCSS/), so it'll be needed to copy those two files from Trive/blank to child theme.
'postcss-import' looks for imported css files inside Trive/theme-name and if it can't find them here, it'll look into Trive/blank. To override existing blank theme css file, add css file with same name and path in child theme. postcss-import will take it instead of Trive/blank css.
File override example: Trive/blank/web/src/preCSS/theme/icons.css -> Trive/theme-name/web/src/preCSS/theme/icons.css
-
gulp
- Default gulp task (runs 'css', 'static', 'watch' & 'browser-sync' tasks). It watches css, html, images & js files. Browser-sync injects css file into the browser. These files, if changed, are auto transferred from theme to pub/static folder, so deployment of Magento static content would not be needed. Gulp-watch package is added to gulpfile so newly added files are watched also. This means it's not needed to restart gulp task anymore. -
gulp clean
- Removes everything invar/cache
,var/generation
,var/view_preprocessed
&pub/static
folder (Except .htaccess, magento blank & magento luma theme) -
gulp deploy
- It's a short ofbin/magento setup:static-content:deploy
. There is no problem to use longer option either :)
-
gulp upgrade
- Short of 'bin/magento setup:upgrade' -
gulp deploy
- Excluded Magento/blank & Mageto/luma by default. Faster deployment this way...
