This topic describes how to deploy an expressCart application to Function Compute. Function Compute provides a method different from traditional deployment methods. You can deploy a traditional expressCart application to Function Compute and use the application for production without performing operations such as purchasing a server. The deployed expressCart application can use the auto scaling, pay-as-you-go, and O&M-free features of Function Compute.

Prerequisites

The following operations are complete:

Background information

An expressCart application is a component based on expressCart, an open source shopping website. You can use this component to deploy your own e-commerce shopping website with high efficiency.

Procedure

  1. Run the following command in the specified directory to initialize a project: 
    s init  start-expresscart
    Sample command output:
    Serverless Awesome: https://github.com/Serverless-Devs/package-awesome

 Specify your project name (init dir) start-expresscart// By default, the system sets the project name for you. You can modify the project name as required. 
 file decompression completed
 Specify the endpoint of the ApsaraDB for MongoDB (Serverless) instance: mongodb://[username:password@]host[:port]// Specify the endpoint of the ApsaraDB for MongoDB (Serverless) instance as required. 

 Thanks for using Serverless-Devs
 You could [cd /test/start-expresscart] and enjoy your serverless journey!
 If you need help for this example, you can use [s -h] after you enter folder.

expressCart:
  serviceName:  expresscart-test
  functionName: express-cart
  domain:       60657313-188077086902****.example.com

Result

After the project is deployed, you can view the temporary domain name generated by Function Compute in the execution output. The temporary domain name can be used to access the newly deployed application. For example, run the following command to access the application: 

curl 60657313-188077086902****.example.com
Note The temporary domain name is used only for demonstration and development purposes. It is valid for a limited period of time. You must use a domain name that has obtained an Internet Content Provider (ICP) filing from Alibaba Cloud for production. For more information, see Configure a custom domain name.
