$ npm install 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 is installed globally by running npm install -g gatsby-cli
.
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"
}
}
All the following documentation is available in the tool by running gatsby --help
.
