EdgeRoutine CLI

Alibaba Cloud Content Delivery Network (CDN) provides the EdgeRoutine CLI tool to run custom JavaScript code on edge nodes. This topic describes how to use the EdgeRoutine CLI tool to deploy JavaScript code.

1. Install the EdgeRoutine CLI tool.
   On the command line of your terminal, run the following command to install EdgeRoutine CLI:

   $ npm install @alicloud/edgeroutine-cli -g

2. Run the following command to create a code directory and switch to the directory.

   $ mkdir yourProject; cd yourProject

3. Initialize the environment and create a code template.
   Run the following command to initialize the environment:

   $ edgeroutine-cli init

   The following example shows a code template. If you want to use your own code, you can move your code file to the code directory that you have created, and name the code file edge.js.

   /**
    * Add the necessary event listener
    * @param {Event} fetch event, {Function} async function
    */
   addEventListener('fetch', event => {
     event.respondWith(handleRequest(event.request))
   })
   /**
    * Make a response to client
    * @param {Request} request
    */
   async function handleRequest(request) {
     return new Response('Hello World!', { status: 200 })
   }

4. Configure the accelerated domain name and AccessKey ID and AccessKey secret.

   $ edgeroutine-cli config

5. Deploy the code to the phased release environment.
   Note Before you deploy the code to the production environment, you must validate the code in the phased release environment.
   1. Build the code in the phased release environment.

      $ edgeroutine-cli build

   2. View the code in the phased release environment.

      $ edgeroutine-cli build --show

   3. Delete the code in the phased release environment.

      $ edgeroutine-cli build --delete

   4. Roll back the code in the phased release environment.

      You can deploy the deleted code to the production environment at your convenience. Before the deployment, you must roll back the code to the status before the code was deleted.

      $ edgeroutine-cli build --rollback

6. Validate the code in the phased release environment.

   You must connect to the accelerated domain name in the terminal environment by using the IP address of the phased environment for EdgeRoutine. The IP address is 42.123.119.50 or 42.123.119.51.

   $ curl -v 'https://yourdomain.com/yourpath/' -x42.123.119.50:80

7. Deploy the code to the production environment.
   1. After you validate the code in the phased release environment, you can deploy the code to the production environment.

      $ edgeroutine-cli publish

   2. View the code in the production environment.

      $ edgeroutine-cli publish --show

   3. Delete the code in the production environment. Then, the code and relevant configurations are deleted. This is an optional step.

      $ edgeroutine-cli publish --delete

8. Test the production environment.
   You can test your workloads of the accelerated domain name.

   $ curl -v 'https://yourdomain.com/yourpath/'
