    If your account is a Tencent Cloud sub-account, please get the authorization from the root account first as instructed in Account and Permission Configuration.


    Quick deployment

    In an empty folder directory, run the following command:


    Next, follow the prompts to initialize the project. Select the application framework template you want to deploy (Express is used as an example here):

    Serverless: No serverless project is detected. Do you want to create one? Yes
    Serverless: Please select the serverless application you want to create: express-starter
      eggjs-starter - quickly deploys a basic Egg.js application 
    ❯ express-starter - quickly deploys a basic Express.js application 
     flask-starter - quickly deploys a basic Flask application 
     fullstack - quickly deploys a full stack application (Vue.js + Express + Postgres) 
     koa-starter - quickly deploys a basic Koa.js application 
     laravel-starter - quickly deploys a basic Laravel application 
     nextjs-starter - quickly deploys a basic Next.js application 
    Serverless: Please enter the project name: demo
    Serverless: Installing the express-starter application...
    express-starter › Created
    The demo project has been successfully created!

    Select Deploy Now to deploy the initialized project to Tencent Cloud:

    Serverless: Do you want to deploy the project in the cloud now? Yes

    After the deployment is completed, click the API Gateway link output by the command line to quickly access the successfully deployed web framework application.

    Viewing deployment information

    If you want to check the deployment status and resources of the application again, you can go to the folder where the project is successfully deployed and run the following command to view the corresponding information:

    cd demo # Enter the project directory. Please change to your actual project's directory name here
    sls info

    sls is short for the serverless command.

    Viewing directory structure

    In the directory of the initialized project, you can see the most basic structure of an Express project:

    ├── serverless.yml  # Configuration file
    ├—— index.js    # Entry function
    ├—— package.json # Project dependencies
    └── .env # Environment variable file
    • The serverless.yml configuration file implements the quick configuration of the basic function information. All the configuration items supported by the SCF console can be configured in the .yml file (for more information, please see SCF Configuration Information).
    • index.js is the entry function of the project, which is the helloworld template here.
    • package is the dependent file of the project, which records the dependency package that should be installed for the Express project.
    • The .env file stores user login authentication information. You can also configure other environment variables in it.


    In the local project directory, you can modify the function template and configuration file, reinstall the dependencies, and then redeploy the project by running the following command:

    npm install && sls deploy

    If you want to view the details during the removal process, you can add the --debug parameter after sls deploy.

    Continuous development

    After the deployment is completed, you can log in to the SLS console to view the monitoring metric data output after project deployment, such as the basic information, the number of project requests, and project error statistics.
    View the monitoring metric data output after project deployment, such as the basic information, the number of project requests, and project error statistics, and implement the continuous development and deployment of the project.

    For more information, see Console Deployment Guide.
    Serverless Framework supports running different commands to help you implement continuous development, deployment, and grayscale release for the project. You can also use this component in conjunction with other advanced capabilities such as layer and custom domain name to configure advanced features for the application.


    • Problem 1: The wizard does not pop up by default when serverless is entered.
      Solution: Add the SERVERLESS_PLATFORM_VENDOR=tencent configuration item to the .env file.
    • Problem 2: After sls deploy is entered in a network environment outside the Chinese mainland, the deployment is very slow.
      Solution: Add the GLOBAL_ACCELERATOR_NA=true configuration item to the .env file to enable acceleration outside the Chinese mainland.
    • Problem 3: Ater sls deploy is entered, the deployment reports a network error.
      Solution: Add the following proxy configuration to the .env file.
      HTTP_PROXY= # Replace "12345" with your proxy port
      HTTPS_PROXY= # Replace "12345" with your proxy port
