Elements CLI

The Elements CLI provides command-line access to the Elements design system. Use it to scaffold new projects pre-configured with Elements, look up component APIs and design tokens, validate templates, and generate shareable playgrounds -- all without leaving your terminal

Install CLI

Install the Elements CLI to your system. This creates a canonical executable path and adds the nve command to your path when possible.

macOS / Linux Windows PowerShell NodeJS

Usage

Project Creation

Use the CLI to quickly bootstrap frontend UIs pre-configured with Elements.

The CLI also can provide API search results withing the terminal.

API Validation

Check paths or glob patterns, or pass one typed document through standard input. Supplied content defaults to HTML; use --lang json with --filename for JSON.

Markdown is the default format. JSON returns ok, complete summary counts, and diagnostics with locations, severity, rule, suggestion, and whether a fix is available. Errors produce a nonzero exit code; warnings do not. The command always uses the recommended Elements rules. Use --max-diagnostics to limit returned findings, and use --fix only with path inputs. It respects .gitignore, skips node_modules, and by default reads at most 200 files, 5 MiB total, and returns 100 diagnostics. It also refuses paths outside the current directory.

Search result output:

Skills

Troubleshooting

403 Forbidden

A 403 Forbidden error means your token has expired. Re-authenticate to resolve it.

Unsupported Engine

An Unsupported engine warning means your Node.js version is out of date. The CLI requires Node.js v20 or later. Update Node.js and try again.
