Once you've added content and configured your book, it's time to build the HTML for each page of your book. We'll use the jupyter-book build command-line tool for this. In the next step, we'll stitch these HTML pages into a book.

Prerequisites

In order to build the HTML for each page, you should have followed the steps in creating your Jupyter Book structure. You should have a Jupyter Book structure in a local folder on your computer, a collection of notebook/markdown files in your content/ folder, a _data/toc.yml file that defines the structure of your book, and any configuration you'd like in the config.yml file.

Build each page's HTML

Now that your book's content is in the content/ folder and you've defined your book's structure in _data/toc.yml, you can build the HTML for each page of your book.

Do so by running the following command:

jupyter-book build mybookname/

This will:

• Use the links specified in the _data/toc.yml file (pointing to files in /content/) and do the following:
  • Run nbconvert to turn the content files (e.g., .ipynb, .md, etc) files into HTML
  • Replace relative image file paths so that they work on your new built book
  • Place all these generated files in the mybookname/_build/ directory.

After this step is finished, you should have a collection of HTML files in your _build/ folder.

Page HTML caching

By default, Jupyter Book will only build the HTML for pages that have been updated since the last time you built the book. This helps reduce the amount of unnecessary time needed to build your book. If you'd like to force Jupyter Book to re-build a particular page, you can either edit the corresponding file in the content/ folder, or delete that page's HTML in the _build/ folder.

Next step: build and publish your book

Now that you've created the HTML for each page of your book, it's time to stitch them together into a book. That's covered in the next section.
