Use this skill when starting a brand-new Salesforce UI bundle app (React or Angular) and the initial project must be scaffolded — trigger phrases include create, start, or scaffold a new UI bundle app, generate a starter project, or use a prebuilt/starter template.

Using a UI Bundle Template

Before building a Salesforce UI bundle app from scratch, offer the user a prebuilt starter template. The Salesforce CLI generates these — a complete, deployable SFDX project (UI bundle + toolchain + an npm run setup automation) — in one command. Starting from a starter is faster and less error-prone than hand-scaffolding.

The CLI command is sf template generate project.

Step 1: Offer the choice

Determine the framework. It is normally already decided by the calling context — either passed down by the root/coordinator skill that invoked this one, or stated in the user's request. Use that.

The frameworks this skill supports are exactly the reference files under <SKILL_DIR>/references/, each named <framework>-project-generate.md (so react → <SKILL_DIR>/references/react-project-generate.md). This is the single source of truth — adding a framework means adding a reference file, nothing here changes.

• If the framework is known — open <SKILL_DIR>/references/<framework>-project-generate.md.
• If it is unknown (a standalone run where nobody said which) — list <SKILL_DIR>/references/, derive the supported set by stripping the -project-generate.md suffix from each filename, and ask the user to pick one of those. If the user names a framework with no matching reference file, it is not supported here — hand off to experience-ui-bundle-app-coordinate to scaffold from scratch.

Each reference lists that framework's --template flags and what each starter contains. Pick the one that fits the user's audience (internal vs. external).

If the user prefers to start from scratch (or neither template fits), stop here and let experience-ui-bundle-app-coordinate scaffold a new project. This skill is opt-in — do not force a template.

Once the user picks, carry the chosen --template flag into Step 2.

Step 2: Generate the project into the target root

The project contents must land directly at the target root $DEST — so sfdx-project.json sits at $DEST/sfdx-project.json, with no extra wrapper subfolder. sf template generate project always nests its output under a --name subfolder, so <SKILL_DIR>/scripts/generate-project.mjs generates into $DEST, flattens the subfolder's contents up into $DEST (overwriting anything already there on conflict), and removes the now-empty subfolder — all through Node's fs/child_process APIs, so it runs the same way on Windows cmd/PowerShell as it does on macOS/Linux/Git Bash.

• <SKILL_DIR> = the absolute path to this skill's own directory — the folder containing this SKILL.md; resolve it from the skill path in context
• $NAME — the project name (alphanumerical only — no spaces, hyphens, underscores, or special characters). Ask the user for it. It also names the UI bundle, so it shows up inside the project.
• $DEST — the target root directory the contents land in (use . for the current directory).
• $TEMPLATE — the --template flag value from the framework reference chosen in Step 1 (e.g. reactinternalapp).

Run the script with the actual, literal values substituted for $NAME, $DEST, and $TEMPLATE — do not use shell variable assignment/interpolation (NAME=... / $NAME / %NAME% / $env:NAME) since that syntax differs across bash, cmd, and PowerShell and this command must work in all three:

node "<SKILL_DIR>/scripts/generate-project.mjs" "<name>" "<dest>" "<template>"

The script prints OK: project root landed at <dest> (...) and exits 0 on success. It exits non-zero (with a clear stderr message) if sf template generate project fails, the generated project has no sfdx-project.json, or the flatten didn't leave a valid project root — stop and surface the failure rather than continuing.

sfdx-project.json must sit at $DEST/sfdx-project.json. The project also contains package.json, force-app/main/default/uiBundles/$NAME/ (the UI bundle), scripts/, config/, and README.md. See the framework reference from Step 1 for the specific bundle contents.

Step 3: Install dependencies (you do this — do NOT hand off uninstalled)

If the generated project ships without node_modules, install dependencies yourself before handing the project back — a fresh template is not runnable (preview/build/lint all fail) until deps are present. The user should receive a ready-to-develop project.

There are multiple package.json files, each needing its own install:

• the project root ($DEST/package.json), and
• the UI bundle dir under $DEST/force-app/main/default/uiBundles/$NAME/ — this holds the toolchain the preview server loads, so it must have node_modules too.

<SKILL_DIR>/scripts/install-deps.mjs runs npm install for the root and for every UI bundle that has a package.json (via Node's child_process with an explicit cwd — no cd && shell chaining), then verifies node_modules landed everywhere it installed:

node "<SKILL_DIR>/scripts/install-deps.mjs" "<dest>"

Substitute the literal $DEST value from Step 2 for <dest>. The script prints OK: all dependencies installed. and exits 0 on success; it exits non-zero with a listed summary of which install(s) failed otherwise. First-run install of the bundle is the heavy step; expect a short wait. If an install fails, surface it — don't hand off a half-installed project.

Step 4: Confirm and hand off

install-deps.mjs already prints a verification summary (root + each UI bundle's node_modules) as part of Step 3. To look around the generated project yourself, use your own file-listing/read tools rather than a shell ls — that works identically regardless of the underlying OS shell.

The project is now ready to develop and deploy. If there's a README.md in the template, take a look at it to see if there is any extra step or guidance for the user.

From here, continue development with the other ui-bundle skills (experience-ui-bundle-frontend-generate, experience-ui-bundle-salesforce-data-access, experience-ui-bundle-deploy, etc.) against the now-scaffolded project — scaffolding and dependency install are already done.

Notes

• The starters are minimal — no seeded sample data or custom objects. Build the rest with the other ui-bundle skills.
• These templates use the uiBundles metadata convention. The UI bundle directory and meta XML are named after the project name you pass to --name.
• sf template generate project --help lists all available templates if the flag names ever change.
