VA.gov Content Build

What is this?

This repository contains scripts and templates which generate static HTML pages for the VA.gov site.

There are several repositories that contain the code and content used to build VA.gov. If you're looking to get started running VA.gov locally, you should read the Setting up your local frontend environment documentation.

Common commands

Once you have the site set up locally, these are some common commands you might find useful:

I want to...	Then you should...
fetch all dependencies	yarn install. Run this any time package.json changes
build static HTML pages	yarn build
run the dev server	yarn serve. Uses port 3002, keeping 3001 free for vets-website dev server
watch for template/css changes	yarn watch. Runs the dev server while watching for changes
build CSS	yarn build:webpack. Runs the webpack
watch for CSS changes	yarn build:webpack --watch. Watch CSS for changes without watching templates
build in codespaces	yarn build:codespaces. Build with codespace options
watch in codespaces	yarn watch:codespaces. Watch with codespace options

Building static content

VA.gov contains many pages that include content generated from a Drupal-based content model. When testing changes to static pages, or to see what your application looks like on VA.gov, follow the sections below to build these static pages.

Prepare Your Environment Settings

The Content-Build can pull fresh content directly from Drupal endpoints. To do this the request for content must be authenticated. If pulling fresh content you must ensure that these command line arguments or environmnet variables are set:

Command Line Argument	Environment Variables	Purpose
--drupal-user	DRUPAL_USERNAME	Name of Drupal user that can read content.
--drupal-password	DRUPAL_PASSWORD	Password of Drupal user that can read content.
--drupal-address	DRUPAL_ADDDRESS	Drupal Endpoint to pull content from.

Authentication credentials are stored in a local .gitignore'd file .env. An example file is provided to get you started:

cp .env.example .env

File contents:

# .env file contents
DRUPAL_ADDRESS=https://content-build-medc0xjkxm4jmpzxl3tfbcs7qcddsivh.ci.cms.va.gov
DRUPAL_USERNAME=content_build_api
DRUPAL_PASSWORD=drupal8

In most cases, these values will be all you need to run a content build with fresh CMS content. However, if you need to connect to a different CMS endpoint, you can either override the values in the .env file, or else override specific values at the command line. For example:

yarn build --pull-drupal --drupal-address=https://some-other-endpoint.cms.va.gov

If you do need to pull content from https://prod.cms.va.gov please contact #cms-support and request a user with permissions to read the Drupal Content API. You will need to use your assigned credentials to access Production.

Build static pages using the following commands:

yarn build (fetches the latest content cache from S3 by default when cache is empty)

• use --pull-drupal to fetch fresh content from Drupal if needed (requires SOCKS proxy access). Add --use-cached-assets to skip asset download
• creates symlink to ../vets-website/build/localhost/generated by default, allowing access to app bundles (use --apps-directory-name to change the default apps directory name; e.g. --apps-directory-name application)
• run once to build the static HTML files
• need to run this again when adding new templates based on new Drupal entities

yarn serve

• starts a local server for the site using the latest build
• use --port to set the port for the server (3002 by default)
• use --buildtype to set the build type (localhost by default)

yarn watch

• watches for changes to liquid templates

yarn preview

• You can run this concurrently with yarn watch. It adds local routes needed to preview Drupal nodes (e.g. /preview?nodeId=XX).

If you do not have access to the SOCKS proxy, you can fetch the latest cached version of the content with the following:

yarn fetch-drupal-cache

Read the Codespaces documentation for this repository.

Running tests

Unit tests

To run all unit tests, use:

yarn test:unit

If you want to run only one test file, you can provide the path to it:

yarn test:unit src/site/filters/liquid.unit.spec.js

To run all tests in a directory, you can use a glob pattern:

yarn test:unit src/site/filters/**/*.spec.js

More commands

After a while, you may run into a less common task. We have a lot of commands for doing very specific things.

I want to...	Then you should...
build the production site (dev features disabled).	NODE_ENV=production yarn build --buildtype vagovprod
fetch the latest content cache from S3	yarn fetch-drupal-cache (does not require SOCKS proxy access)
reset local environment (clean out node modules and runs npm install)	yarn reset:env
run the site so that devices on your local network can access it	yarn watch --env.host 0.0.0.0 --env.public 198.162.x.x:3001 Note that we use CORS to limit what hosts can access different APIs, so accessing with a 192.168.x.x address may run into problems
run all unit tests and watch	yarn test:watch
run only E2E tests (headless)	Make sure the site is running locally (yarn watch) and run the tests with yarn cy:run
run E2E tests in the browser	yarn cy:open
run all linters	yarn lint
run only javascript linter	yarn lint:js
run lint on JS and fix anything that changed	yarn lint:js:changed:fix
run visual regression testing	Start the site. Generate your baseline image set using yarn test:visual:baseline. Make your changes. Then run yarn test:visual.
test for broken links	Build the site. Broken Link Checking is done via a Metalsmith plugin during build. Note that it only runs on build not watch.
add new npm modules	yarn add my-module. Use the --dev flag for modules that are build or test related.
get the latest json schema	yarn update:schema. This updates our vets-json-schema vets-json-schema https://github.com/department-of-veterans-affairs/ to the most recent commit.
check test coverage	yarn test:coverage
