Projects

A MappView project captures your whole workspace in a single .mappview.json file: the map view, the basemap, every layer with its source and style, map preferences, plugin state, and environment variables. Everything in this section lives under the Project menu.

New

Project → New… starts a fresh project. MappView offers to save the current project first, then resets the layers, map view, controls, and plugin state to defaults.

Open

Project → Open From has two sources:

• File… opens a .mappview.json file from disk (desktop app).
• URL… loads a public .mappview.json from an HTTP or HTTPS URL. This works in the browser too and adds the project to your recent list.

Project → Open Recent lists the projects you have opened before, each with its name, path, and the time you last opened it. Click an entry to reopen it, use the small remove button to drop a single entry, or choose Clear Recent Projects to empty the list. On the desktop app the recent list persists across sessions; in the browser it tracks URL-based projects.

!!! note “Loading a project at startup” You can open a project directly by passing its URL with the url query parameter, for example ?url=https://share.example.com/you/project.mappview.json. See Embedding & Sharing.

Save and Save As

• Save writes back to the project’s existing file path.
• Save As… prompts for a new name and location.

Both capture the current map view, basemap, layers, styles, preferences, and plugin state at the moment you save. Projects that were opened from a URL have no writable local path, so both Save and Save As fall back to the save dialog. Saving requires the desktop app.

Share

Project → Share… uploads the current project to the configured MappView Share service and returns a public URL you can send to anyone or open in the viewer. Sharing uses a personal API token, which you set once as the MappView API token in Settings → Environment Variables. The shared file is the same .mappview.json the app saves locally, so anyone who opens the link sees the same layers, styles, and map view. See the Sharing & Embedding tutorial.

Print

Project → Print… opens the Print panel, which exports the current map to a PDF or image. Choose the page size and orientation, then export. The Print panel is backed by the MapLibre components plugin.
