OSCAL Website

This subdirectory contains source code for the OSCAL website at https://pages.nist.gov/OSCAL. Below are instructions for building the site for local development if making any contributions to the documentation.

The website is built using the Hugo static site generator and the United States Web Design System (USWDS).

Prerequisites

If using Docker:

If not using Docker:

  • macOS, Linux or Windows Subsystem for Linux (WSL) (model doc build scripts don't support Windows natively at this time)
  • Saxon-HE for Java
  • Hugo

Generating the model documentation

Before you can build and serve the site using Hugo directly or Docker, you must generate the OSCAL model documentation using the provided shell scripts. This step assumes that you've already downloaded Saxon-HE for Java and that you've set the $SAXON_HOME environment variable in your shell to the directory in which you extracted Saxon-HE.

From the root directory of the repository, execute the following command to generate the model documentation:

./build/ci-cd/generate-model-documentation.sh

Using Hugo

Hugo is a popular open source static site generator that is used to develop all of the content for the OSCAL website. It is a general-purpose framework that builds pages when the content is created or updated.

Instructions for installing the Hugo CLI on your OS can be found here.

The website's visual styling is also backed by the U.S. Web Design System (USWDS) via an open source Hugo theme at https://github.com/usnistgov/hugo-uswds.

The USWDS framework is documented here: https://designsystem.digital.gov/.

Building the site with LiveReload

Hugo provides built-in LiveReload which watches for any changes to the source content and automatically reloads the site when changes are detected.

  1. Pull the currently used USWDS Hugo theme revision to your locally cloned copy of the OSCAL repo by executing the following command from within the folder of the git repo
git submodule update --init
  1. Verify that Hugo is installed
hugo version

NOTE: The extended version of Hugo is required. The reported version should include the word "extended".

  1. Navigate into the docs/ directory
cd docs
  1. Start the Hugo server
hugo server -v --debug --minify

alternatively, you may bind Hugo to a network adapter on your workstation using its assigned IP address

hugo server -v --debug --minify --bind [ipv4-address] -b http://[ipv4-address]:1313/OSCAL
  1. Open your browser and navigate to http://localhost:1313/OSCAL to view the locally built site.

If you bound Hugo to an IP address, navigate to http://[ipv4-address]:1313/OSCAL either locally or with another device on the network.

Whenever you make any changes to the content with the Hugo server running, you'll notice that the site automatically updates itself to reflect those changes.

Developing with Docker

The website can also be developed and built using the included Docker resources.

Assuming you've installed Docker and Docker Compose for your system, you can build and serve the site using Docker Compose as follows:

docker compose build
docker compose up

Once the site is running, it can be accessed at http://localhost:1313/OSCAL. Whenever you make any changes to the content with the Hugo server running, you'll notice that the site automatically updates itself to reflect those changes.
