This topic describes how to deploy an Egg.js application to Function Compute. Function Compute provides a method different from traditional deployment methods. You can deploy a traditional Egg.js application to Function Compute and use the application for production without performing operations such as purchasing a server. The deployed Egg.js 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

Egg.js is designed to build enterprise frameworks and applications, and provides developers with core features for web development and a plug-in mechanism that has high extensibility. The developers develop applications based on a unified agreement. This reduces development and maintenance costs. For more information, see What is Egg?

Procedure

  1. Run the following command in the specified directory to initialize a project:
    s init devsapp/start-egg -d start-egg
    The -d parameter specifies the project name. In this example, the project name is start-egg.
    Note Skip this step if the item exists.
    Sample command output:
     Serverless Awesome: https://github.com/Serverless-Devs/package-awesome

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 http://egg.serverless-devs-egg.188077086902****.cn-shenzhen.fc.devsapp.net
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.
