Usage

In its simplest form:

npm create @fastly/compute

You may also pass a number of optional command line options, in the form of npm create @fastly/compute -- [<options>]:

  --directory=<pathspec>        - Specifies the directory to create the new
                                  application. If the directory exists, it
                                  must be empty. Defaults to the current
                                  directory.
  --author=<author-name>, ...   - Sets the author(s) in fastly.toml.
  --language=<lang>             - Used to select a category of starter kit.
                                  Can be 'javascript' or 'typescript'.
                                  Cannot be used with --from.

                                  Cannot be used with --default-starter-kit,
                                  --list-starter-kits, or --from.
  --default-starter-kit         - Uses 'default' as the starter kit.
                                  Equivalent to --starter-kit=default.
                                  Cannot be used with --starter-kit,
                                  --list-starter-kits, or --from.
  --list-starter-kits           - Fetches a list of available starter kits
                                  and outputs it.
                                  Cannot be used with --starter-kit,
                                  --default-starter-kit, or --from.
  --from=<pathspec-or-url>      - Specifies a directory with a fastly.toml,
                                  a URL to a GitHub repo path with a
                                  fastly.toml, or a URL to a Fiddle, and
                                  will be used as the starting point of the
                                  new application.
                                  Cannot be used with --language,
                                  --list-starter-kits, or --starter-kit.
  --fastly-cli-path=<pathspec>  - By default, this initializer uses a
                                  built-in copy of the Fastly CLI. Use this
                                  option to specify the path of an
                                  alternative Fastly CLI to use.
  --no-confirm                  - Do not show confirmation prompt before
                                  creating the application.

Selecting a Starter Kit

After choosing a language (or specifying one via --language), you are prompted to select a starter kit. The initial list will contain a small selection of common starter kits. If you wish to pick from the full list of Fastly-provided Starter Kits for the selected language, select Choose a starter kit from GitHub., and the tool will query GitHub for the widest selection.

Specifying a template

By using the --from option, or by selecting Specify starter kit or directory from the interactive prompts, you may specify an existing Compute JavaScript application to base your new application from. You may provide one of the following:

• A path to a local directory that contains a Compute program, e.g., /path/to/existing/app.
• A direct URL to a GitHub repository of a Fastly Compute Starter Kit.
• A URL to a Fastly Fiddle. This should take the form of https://fiddle.fastly.dev/fiddle/<fiddle-id>.

Listing available Starter Kits and selecting from them

To obtain a complete list of available starter kits, use the --list-starter-kits option:

npm create @fastly/compute -- --list-starter-kits

Sample output:

Available starter kits:

Language: javascript
  [default] - Default package template for JavaScript based Fastly Compute projects
  [empty] - Empty package template for JavaScript based Fastly Compute projects

To initialize a project with a Starter Kit, specify it using the identifier within the brackets (such as default and empty) for the --starter-kit=<id> value.

Fastly CLI

By default, this initializer uses a copy of the Fastly CLI builtin to it. Alternatively, to use a copy of the Fastly CLI (version >= 10.0.0) available on your system, specify it using the --fastly-cli-path option:

npm create @fastly/compute -- --fastly-cli-path=/path/to/fastly

Prerequisites:

• Node.js >= 18
