The SLS framework deployment scheme has been upgraded. You can use an SCF HTTP-triggered function to quickly deploy your Express service to the cloud.
Note:What are the differences between SLS console deployment and direct function deployment?
Both SLS console deployment and function deployment can be based on HTTP-triggered functions, and quick deployment is usually used for web frameworks.
This document introduces the SLS console deployment scheme. You can also complete the deployment in CLI by referring to Deploying Web Function on Command Line.
The Node.js runtime environment has been installed locally.
npm install express --save
npm install express-generator --save
express WebApp
cd WebApp
npm install
http://localhost:3000
in a browser, and you can access the sample Express project locally.npm start
Next, perform the following steps to make simple modifications to the initialized project, so that it can be quickly deployed through an HTTP-triggered function. The project transformation here is usually divided into the following two steps:
0.0.0.0:9000
.scf_bootstrap
file.The detailed steps are as follows:
In the sample Express project, you can specify the listening address and port through the environment variable in the ./bin/www
file. If you don't specify it, port 3000 will be listened on by default.
Create the scf_bootstrap
file in the root directory of the project. This file is used to configure environment variables and specify service start commands.
Note:You can also complete the configuration in the console.
#!/bin/bash
export PORT=9000
npm run start
After the file is created, you need to run the following command to modify the executable permission of the file. By default, the permission 777
or 755
is required for the service to start normally.
chmod 777 scf_bootstrap
You can configure the scf_bootstrap
file in the console. When the configuration is completed, the console automatically generates the scf_bootstrap
file and packages it and the project code for deployment.
Note:The actual
scf_bootstrap
file in your project prevails. If thescf_bootstrap
file already exists in your project, its content will not be overwritten.
When the configuration is completed, click Complete to deploy your Express project.
