Install and verify

Install WorkSpec with Node.js and verify the CLI and JavaScript package.

This tutorial prepares a local project to use WorkSpec from the terminal and JavaScript.

Prerequisites

Install Node.js 18 or a later version. Confirm the installed versions:

Terminal

node --version
npm --version

Install WorkSpec

Create a project directory and enter it.
Terminal
```
mkdir parcel-workflow
cd parcel-workflow
```
Create a local npm project.
Terminal
```
npm init --yes
```
Install WorkSpec.
Terminal
```
npm install workspec
```
Print the installed package version.
Terminal
```
npx workspec --version
```
The command prints a package version such as:
Text
```
1.2.5
```
Optional: Install WorkSpec globally to run workspec without npx.
Terminal
```
npm install --global workspec
workspec --version
```

Package version and language version

The command prints the npm package version. Your project files declare the WorkSpec language version separately.

Next step

Build your first WorkSpec project with validation, a snapshot, a Constraint, and SVG rendering.
