Certain hierarchies are not appearing

If you're only publishing a sub-set of your notes (i.e. not everything under root), all the hierarchies you want to appear on the site must be listed in dendron.yml under siteHierarchies. E.g.

        - topics
        - projects
        - areas

My favicon isn't showing up

This might be due to favicon caching on localhost. It should resolve when published.

Search isn't working on the site

This could be the result of a CORS issue. Make sure that both siteUrl and cname are referring to the same domain.

This is good


This is bad


My image isn't showing up

  • Make sure your images have a leading /. So /assets/images/foo.jpg instead of assets/images/foo.jpg.
  • If you are publishing to GitHub, check if assetsPrefix is set

Command failed when installing or upgrading dependencies

Command failed with ENOENT: npm install 

This could be due to multiple reasons:

- Make sure the default shell you have for VS Code is set to a shell that has npm in it. See [here]( for changing your default shell.
- Make sure that `package.json` is not open during installation (you might see `operation not permitted` on windows)


Inspect and Kill Existing Process

Dendron runs the preview on port 8080. Make sure you don't have something already running there.

  • windows
# get ids of processes
Get-Process -Id (Get-NetTCPConnection -LocalPort 8080).OwningProcess

# if you see any result, you can stop them using the following command
Stop-process -Id {IDS_FROM_ABOVE}
  • linux
# get ids
lsof -l -n -P -i tcp:8080 

# kill
kill -9 {IDS}
