Overview

This task shows you how to use Serverless Framework to quickly create, configure, and deploy a Serverless application on Tencent Cloud.

Note：

• Serverless Framework provides a Visualized Page for you to view and manage the resources of a Serverless application.
• Serverless Framework Component V2 has been released. We advise you to use the latest version.

Prerequisites

• Ensure that Serverless Framework 1.67.2 or later has been installed in advance.
• If your Tencent Cloud account is the root account, you can continue implementing deployment. If your account is a sub-account, please go to Account and Permission Configuration to get permission before implementing deployment.

Directions

Creating an Application

You can run the sls init command to quickly create an SCF, Express.js, or static website hosting application. For example, to create an Express.js application:

sls init express-demo

Note：

You can run the sls registry command to view the supported demo.

Go to the express-demo directory and perform deployment:

cd express-demo && sls deploy

After the deployment is completed, visit the URL returned from the CLI to access the deployed application.

Note：

To view the detailed information during deployment, you can add the --debug parameter.

Viewing the Deployment Information

To view the application deployment statuses and resources again, go to the directory that is successfully deployed and run the following command:

$ cd express-app #Go to the project directory.
$ sls info

Note：

sls is short for the serverless command.

Developing and Debugging

Run the sls dev command to enable the real-time deployment log. This capability automatically detects the updates of the local code and deploys the updates on cloud. In addition, the invoked log can be output in real time. For a Node.js 10 application, cloud debugging is available. For more information, please see “In-cloud Debugging: Node.js 10+” in Development Mode and In-cloud Debugging

$ cd express-app
$ sls dev

Removing the Project

Run the sls remove command to remove all on-cloud resources, as shown below:

$ cd express-app #Go to the project directory.
$ sls remove
