gatsby-cli

The Gatsby command line interface (CLI). It is used to perform common functionality, such as creating a Gatsby application based on a starter, spinning up a hot-reloading local development server, and more!

Lets you create new Gatsby apps using Gatsby starters. It also lets you run commands on sites. The tool runs code from the gatsby package installed locally.

The Gatsby CLI (gatsby-cli) is packaged as an executable that can be used globally. The Gatsby CLI is available via npm and should be installed globally by running npm install -g gatsby-cli to use it locally.

Run gatsby --help for full help.

You can also use the package.json script variant of these commands, typically exposed for you with most starters. For example, if we want to make the gatsby develop command available in our application, we would open up package.json and add a script like so:

{
  "scripts": {
    "develop": "gatsby develop"
  }
}
