Digital Experience Site for React UI Bundles

Create and configure Digital Experience Sites that host React UI bundles on Salesforce. This skill generates the minimum necessary site infrastructure — Network, CustomSite, DigitalExperienceConfig, DigitalExperienceBundle, and the sfdc_cms__site content type — so a React app can be served from Salesforce.

React sites differ from standard LWR sites: they don't need routes, views, theme layouts, or branding sets. The site acts as a thin container (appContainer: true) that delegates rendering to the React UI bundle referenced by appSpace.

Required Properties

Resolve all five properties before generating any metadata. Each has a fallback chain — work through each option in order until a value is found.

The appNamespace and appDevName properties record the intended UIBundle binding for a future follow-up update; they are not substituted into appSpace at initial site creation. appSpace in the sfdc_cms__site content.json is always "" at initial creation — see [configure-metadata-digital-experience.md](references/configure-metadata-digital-experience.md) for the reason and the follow-up flow.

Language Properties

The skill always emits sfdc_cms__languageSettings alongside sfdc_cms__site. Resolve defaultLocale for every site (defaults to en_US); resolve languages only when the user requests additional languages beyond the default.

The content-item folder name (languages), title (LanguageContent), and urlName (languagecontent) are fixed Experience Builder auto-defaults — they are not user-authored. See [configure-metadata-language-settings.md](references/configure-metadata-language-settings.md).

Pre-flight: Target Org Release (Multi-Language Only)

The sfdc_cms__languageSettings content type accepts multi-language declarations only on Salesforce Release 264 (API v68.0 or higher). Sites reduced to a single-locale en_US declaration work on any org and do not need this check.

When the user requests multiple languages, verify the target org's maximum supported API version before writing any metadata. sf api request rest hits /services/data/ on the instance directly and handles authentication at the transport layer, so the org's true ceiling is returned without any access token entering this script's context.

MAX_API=$(sf api request rest "/services/data/" --target-org "${usernameOrAlias}" \
          | jq -r '[.[].version | tonumber] | max')

awk -v v="$MAX_API" 'BEGIN{ exit !(v+0 >= 68.0) }' \
  || { echo "ERROR: multi-language site containers require Salesforce Release 264 (API v68.0+). Target org's maximum supported API version is v${MAX_API}. Retarget to a Release 264+ org, or reduce the site to a single-locale (en_US) declaration." >&2; exit 1; }

If the check fails, do not write metadata. Report the version mismatch to the user and stop.

Generation Workflow

Step 1: Resolve All Required Properties

Determine values for all five required properties and the defaultLocale language property before constructing anything. Use the resolution strategies in the tables above, falling through each option until a value is found. Resolve the languages property only when the user has requested multiple languages — and when they do, run the [Pre-flight](#pre-flight-target-org-release-multi-language-only) check above before continuing to Step 2.

Step 2: Create the Project Structure

Use available Salesforce metadata schema and field context for Network, CustomSite, DigitalExperienceConfig, and DigitalExperienceBundle to ensure each file uses valid structure.

Create any files and directories that don't already exist, using these paths:

Each DigitalExperience content-type directory contains only meta.json and content.json. Both sfdccms__site and sfdc_cms__languageSettings are always required inside the bundle. The sfdc_cms__languageSettings default declares only the resolved defaultLocale (e.g. en_US); it is extended with additional languages when the user requests multi-language support. No other content types are permitted.

Step 3: Populate All Metadata Fields

Use the default templates in the docs below. Values in {braces} are resolved property references — substitute them with the actual values from Step 1.

For URL updates, see [update-site-urls.md](references/update-site-urls.md).

Execution Note for Step 3: Load and use the docs

• Agents MUST read the full contents of each references/*.md file referenced in Step 3 before attempting to populate metadata fields.
• Use your platform's file-read tool (for example, read_file) to load these files in full, then perform placeholder substitution for values in {braces} using the resolved properties from Step 1.
• Files to load:

- references/configure-metadata-network.md - references/configure-metadata-custom-site.md - references/configure-metadata-digital-experience-config.md - references/configure-metadata-digital-experience-bundle.md - references/configure-metadata-digital-experience.md - references/configure-metadata-language-settings.md

• Read entire file contents, replace placeholders (e.g. {siteName}) with the resolved values, then use the expanded templates to populate the metadata XML/JSON content.

Step 4: Do Not Modify Non-Templated Properties

Do not modify any default property values for Network, CustomSite, DigitalExperience, DigitalExperienceConfig, or DigitalExperienceBundle metadata that are not expressed as variables wrapped in {braces}.

Verification Checklist

Before deploying, confirm:

• All five required properties are resolved, and defaultLocale is resolved (defaulting to en_US when the user does not specify one)
• All metadata directories and files exist per the project structure
• All metadata fields match the Step 3 templates with {braces} substituted only; no other default property values were added or changed
• appSpace in sfdc_cms__site content.json is the empty string "" (initial site creation never binds appSpace; that is a separate follow-up update after the UIBundle is deployed to the target org)
• The sfdc_cms__languageSettings/languages/ files exist. The language declaration satisfies every platform rule below:

- [ ] defaultLocale matches the locale of one declared language, which is active - [ ] every locale is Salesforce-supported, every language is isActive: true, each locale + label combination is unique, and the number of declared languages does not exceed the platform maximum - See [configure-metadata-language-settings.md](references/configure-metadata-language-settings.md) for the full rule catalog. Single-language default declarations satisfy every rule trivially.

• Deployment validates successfully (the DigitalExperience type already covers sfdc_cms__languageSettings — no change to the --metadata list is needed):

sf project deploy validate --metadata Network CustomSite DigitalExperienceConfig DigitalExperienceBundle DigitalExperience --target-org ${usernameOrAlias}

Common Workflows

Updating Experience Site URLs

Use when user wants to update or change site URLs (urlPathPrefix).

Steps:

• Read [update-site-urls.md](references/update-site-urls.md) to understand the three-component architecture and URL update workflow
• Follow the step-by-step workflow in the doc to update URLs consistently across all three components (DigitalExperienceConfig, Network, CustomSite)

Configuring Multi-Language Support

Use when user wants the site to support multiple languages, locales, internationalization, or translation — beyond the default-locale-only declaration that every site already receives.

Steps:

• Collect the additional languages the site should support and which locale is the default (resolve the defaultLocale and languages properties above)
• Run the [Pre-flight: Target Org Release](#pre-flight-target-org-release-multi-language-only) check — abort if the org is below Release 264 (API v68+)
• Read [configure-metadata-language-settings.md](references/configure-metadata-language-settings.md) for the templates, field reference, and platform validation rules
• Extend the sfdc_cms__languageSettings/languages/content.json (which already exists with the default locale) to include the additional language entries, then re-run deploy validation

Note: This is authoring-only — declared locales deploy cleanly, but locale-in-path routing does not resolve at request time yet. Do not translate the UI bundle content itself; this only declares the site's supported languages.
