Bulk download Modeler files

[engineering-issue-sync-app[bot]]

Value Proposition Statement 🚀

Easily download the contents of your web modeler project for offline development or storage in version control

User Problem 🤦

Individual files can be downloaded through a menu in the editing screen, but it's not easy to find Many files can be downloaded through API, but it's not well adopted This doesn't provide a good user experience.

Release Notes 📝

The Web Modeler UI now supports bulk download files within a project to serve as backups or easily copy to a local folder synchronized with their version control system. See the documentation for more details

User Stories 🧑‍🚀

• [x] (M) (Primary) Download all files in a given container (e.g. project OR folder) to work locally.
• [x] (S) (Secondary) Download a single file to hand off to someone else. It's important that single files are not zipped.
• [x] (C) (Tertiary) Download all the files that changed after a certain date. This can be accomplished by sorting by "Last Changed"
• [x] (C) (Tertiary) Bulk download of arbitrarily nested folders
• [x] ~(W) (Out of scope) Bulk upload of arbitrarily nested folders~

Implementation 👷

• The user should know what to expect. Personally, I would expect any download of >1 files to be in ZIP format)
• An off-the-shelf library should cover this use case. I'd expect around 5MB and 25 files, but that doesn't have to be a hard limit
• The roundtrip experience from modeler to desktop is important. We should not offer features (e.g. preserve folder structure) that make it harder for users to upload their content
  • Note: uploading folders to Web Modeler silently fails
• In the future, we may wish to consider export/import of process applications. The roundtrip experience will become more important.
• Downloading through the diagram also gives the option to download PNG or SVG. Alternate filetypes are out of scope

Hi there, I just wanted to pass along a piece of feedback we received recently. A user tried to export the projects but couldn't find the way to do it. They didn't make it to the model itself. They were expecting to find it in the Project view

or at least on the project list

Thanks!

Hi @maria-alcantara, Thanks for sharing this feedback! We will soon introduce the option to download files or folders from the project page.
