In the PR Remove gulp and upgrade webpack by vimal1083 · Pull Request #2748 · HyphaApp/hypha · GitHub we have removed Gulp and replaced it with Webpack and plain npm scripts. The main reson was to bring down the number of security issues regarding outdates npm packages.
Examples of new/old commands:
gulp deploy → npm run build
gulp watch → npm run watch
See package.json for all commands.
I have updated Local Development from Scratch - Hypha Docs.
