Will quarto preview also do the works that quarto render do? Where is the output of quarto preview?

Description

quarto render is very slow and renders every file every time. I have 20+ ipynb files in a project using quarto to render, and it take me about half an hour to see it finish, even if I only add a single small change to existing file and even if I only add a new ipynb file that is independent of the previous ones. When some types of contents that are fine in vscode jupyter notebook fails to compile in quarto, I spend hours on debugging this.

quarto preview can be faster since it watch file changes. However, I don't know where to find the files rendered by quarto preview. After all, I want to publish my docs, so I need the files, not the just the web page showing in my browser.

It seems Documentations https://quarto-dev.github.io/quarto-r/reference/quarto_preview.html and https://quarto.org/docs/tools/text-editors.html didn't cover this, so I came here to ask a question.

I've seen this discussion #4684

The output are located either next to the Quarto document used as input or inside the output-dir if you set one.
The behaviour is the same with quarto render and quarto preview.
quarto preview is quarto render + watching input files + opening the rendered files.

Note that the R package is only a wrapper and is not the main tool.
Use quarto --help to get Quarto CLI helps.

didn't cover this, so I came here to ask a question.

How so? From the link you shared I can read:

The document will be rendered and a web browser with a “live preview” opened.

And there is a "render without preview" section: https://quarto.org/docs/tools/text-editors.html#render-without-preview

What's not clear or missing?

Regarding you project taking time, are you leveraging caching/freezing?

Incremental rendering?

Don't quarto render/preview, do quarto render/preview path/to/my/new/file.qmd/ipynb.
