CLI

Cloudflare provides a CLI command for creating new Workers and Pages projects — npm create cloudflare, powered by the create-cloudflare package ↗.

Create a new application

Open a terminal window and run:

Terminal window
npm create cloudflare@latest

Running this command will prompt you to install the create-cloudflare ↗ package, and then ask you questions about the type of application you wish to create.

Web frameworks

If you choose the “Framework Starter” option, you will be prompted to choose a framework to use. The following frameworks are currently supported:

When you use a framework, npm create cloudflare directly uses the framework’s own command for generating a new projects, which may prompt additional questions. This ensures that the project you create is up-to-date with the latest version of the framework, and you have all the same options when creating you project via npm create cloudflare that you would if you created your project using the framework’s tooling directly.

Deploy

Once your project has been configured, you will be asked if you would like to deploy the project to Cloudflare. This is optional.

If you choose to deploy, you will be asked to sign into your Cloudflare account (if you aren’t already), and your project will be deployed.

Creating a new Pages project that is connected to a git repository

To create a new project using npm create cloudflare, and then connect it to a Git repository on your Github or Gitlab account, take the following steps:

  1. Run npm create cloudflare@latest, and choose your desired options
  2. Select no to the prompt, “Do you want to deploy your application?“. This is important — if you select yes and deploy your application from your terminal (Direct Upload), then it will not be possible to connect this Pages project to a git repository later on. You will have to create a new Cloudflare Pages project.
  3. Create a new git repository, using the application that npm create cloudflare@latest just created for you.
  4. Follow the steps outlined in the Git integration guide

CLI Arguments

C3 collects any required input through a series of interactive prompts. You may also specify your choices via command line arguments, which will skip these prompts. To use C3 in a non-interactive context such as CI, you must specify all required arguments via the command line.

This is the full format of a C3 invocation alongside the possible CLI arguments:

Terminal window
npm create cloudflare@latest [--] [<DIRECTORY>] [OPTIONS] [-- <NESTED ARGS...>]

  • DIRECTORY string optional

    • The directory where the application should be created. The name of the application is taken from the directory name.

  • NESTED ARGS.. string[] optional

    • CLI arguments to pass to eventual third party CLIs C3 might invoke (in the case of full-stack applications).

  • --category string optional

    • The kind of templates that should be created.

    • The possible values for this option are:
