Serverless Scripting CLI

StackPath's serverless scripting platform allows you to add custom logic to your applications or even build entire applications on the edge. A single deployment distributes your scripts across StackPath's vast network containing over 45 POPs.

This CLI makes deploying as easy as running a single command, no matter the number of scripts you have. It's easy to use, but allows for a variety of use cases. Run the CLI locally to make for fast deployments, run it in a CI/CD pipeline to automate deployments, or implement it in any other way you can think of.

Installation

Run any of the following commands to install the CLI depending on your platform and preferences:

Using NPM

Run npm install -g @stackpath/serverless-scripting-cli to install sp-serverless as a global package.

Using Yarn

Run yarn global add @stackpath/serverless-scripting-cli to install sp-serverless as a global package.

Using Homebrew or Linuxbrew

StackPath maintains a Homebrew tap for users to access utilities through the popular Homebrew and Linuxbrew package managers for macOS and Linux.

Run brew tap stackpath/stackpath to install the tap, then run brew install sp-serverless to install the sp-serverless utility.

Configuration

Perform the following to configure the CLI utility after it's installed:

Setting authentication details

The CLI saves your authentication data in a file in your home directory (~/.stackpath/credentials). Once this is set up, the CLI will continue to read the credentials from the file, meaning you don't have to provide your credentials over and over again.

You need a StackPath API client ID and client secret in order to authenticate. You can find them in the StackPath customer portal.

Authenticating in an interactive environment (e.g. on your local machine)

Run sp-serverless auth to authenticate in an interactive environment. The CLI will prompt you for required details.

Authenticating in a non-interactive environment (e.g. in a CI/CD pipeline)

Are you integrating the CLI with a non-interactive environment? Then provide the client ID and the client secret as flags of the command. For example:

sp-serverless auth --client_id example-client-id --client_secret example-client-secret --force

Use the --force (or -f) flag so that the credentials file is always overwritten, even if it already exists.

Configuring a project

The serverless scripting CLI works with a per-project (or per-directory) based configuration. Each project should have its own configuration file defining the scripts that apply to that project. You might use it to order scripts by site, category (such as firewalls), or otherwise.

Start by creating a sp-serverless.json file in your project's directory.

The configuration file

When deploying via sp-serverless deploy, the CLI looks for the sp-serverless.json configuration file in the directory you're running the command from. Through this file you can configure which scripts you'd like to deploy to which site. For example:

{
  "stack_id": "2dad0e92-61f1-4fb2-bbc0-0c26466e91bf",
  "site_id": "1cb3a9ba-06a4-4528-96a4-c4e04598c856",
  "scripts": [
    {
      "name": "Admin IP firewall",
      "paths": [
        "admin/*"
      ],
      "file": "serverless_scripts/ip-firewall.js",
      // The ID is generated on first deploy, or optionally you can configure it yourself.
      "id": "dcdf7824-b6bd-42b8-9b16-9235eefd583d"
    },
    {
      "name": "Script to show a deploy to a different site",
      "paths": [
        "demo/*"
      ],
      "file": "serverless_scripts/demo.js",
      "site_id": "15ece821-9eed-4590-9577-b83beda947f7"
    },
    {
      "name": "Script to show a deploy to a different site and stack",
      "paths": [
        "demo/*"
      ],
      "file": "serverless_scripts/demo.js",
      "site_id": "15ece821-9eed-4590-9577-b83beda947f7",
      "stack_id": "7be2de57-d6d9-4c27-8361-aef01e1870f0"
    }
  ]
}

Note that you can define the site_id either in a global scope or in a per-script scope. This allows you to deploy to different sites from a single configuration file.

The configuration file contains the following parameters:

stack_id: The ID or slug of the stack where your site is in
site_id: The ID of the site to apply the scripts to
scripts[name]: The name of the script. This should be descriptive and unique to each site
scripts[paths][]: The HTTP request paths the script should apply to, relative to the site root and without an initial /. For example, use the path admin/* to apply the script to requests to https://example.org/admin/*
scripts[file]: The local path to the JavaScript file to use as the serverless script, relative to sp-serverless.json's path and without an initial /.
scripts[id]: The ID of the script in the serverless scripting platform. This is created after your first deployment. It should be checked into version control after being created

Finding the stack slug and site ID

Find the stack slug and site ID in the URL when you're logged into the StackPath customer portal and have selected the CDN site you'd like to deploy scripts to.

Deploying serverless scripts

Run sp-serverless deploy from your project directory. To push your configured scripts to the StackPath edge.

Deploying from a non-interactive environment

The CLI may prompt you in certain situations when deploying scripts. For example, if your sp-serverless.json file contains an ID that cannot be found in the platform, the CLI will then prompt you if you'd like to re-create the script. Use the --force or -f flag to always try to re-create the script.

Development

Development requires nodejs versions 10 and up. The CLI doesn't have any build commands. Make code changes and run yarn test to run the test suite or bin/run to test changes directly.
