I would love to see some sort of frontend build process similar to what Integrated Composer does for the Drupal source code.
Using the Integrated Composer workflow, Pantheon attaches a build artifact for release. Assuming that you already have an existing CI workflow in place to handle the frontend side of things, that’s awesome!
If Pantheon had support for compiling SASS files and minifying JavaScript through something like Gulp – I think it would really push the platform to the next level. Just imagine being able to set up a custom upstream with the code in place to run a gulp build
command and the resulting files getting attached to the build artifact!
