Function Compute (2.0):Deploy a code package

Preparations

1. Create a code directory for tests and specify a name for the directory. In this example, mycode is used.

   • Linux and macOS

     Run the mkdir -p /tmp/mycode command to create the directory.

   • Windows

     Create a folder and name it mycode.

2. In the mycode directory, create the index.js or index.mjs file.

   Sample code:

   ECMAScript modules

   Note

   This example supports only Node.js 18 or later.

   // index.mjs
   'use strict';
   import * as emoji from 'node-emoji'
   
   export const handler = async (event, context) => {
     console.log('hello world');
     return emoji.get(':unicorn:');
   }
   

   CommonJS modules

   // index.js
   'use strict';
   var emoji = require('node-emoji')
   
   exports.handler = (event, context, callback) => {
     console.log('hello world');
     callback(null, emoji.get(':unicorn:'););
   }
   

Use npm to install dependencies and deploy code

Prerequisites

• npm is installed on your on-premises machine, and the permissions to execute npm commands are obtained.

• A Node.js function is created in the Function Compute console. For more information, see Create a function.

Procedure

1. Run the npm install node-emoji command in the mycode directory to install the emoji dependency library to the current directory.

2. Package files in the mycode directory.

   • Linux and macOS

     Go to the mycode directory and run zip code.zip -r ./*.

     Note

     Make sure that you have the read and write permissions on the directory.

   • Windows

     Go to the mycode directory, select all files, right-click the files, and then compress the files into a ZIP package.

   Note

   Make sure that the index.js file that you created is located in the root directory of the package.

3. In the Function Compute console, find the desired function. In the upper-right corner of the function details page, click Upload Code to upload the ZIP package.

Use Serverless Devs to install dependencies and deploy the project

Before you start

• Install Serverless Devs and Docker

• Configure Serverless Devs

Procedure

1. Run the cd /tmp/mycode command to go to the mycode directory.

2. Create the s.yaml file.

   The following sample code provides an example of the file:

   edition: 1.0.0          # The version of the YAML specification. The version complies with semantic versioning.
   name: fcDeployApp       # The name of the project.
   access: "default"  # The alias of the key.
   
   services:
     fc-deploy-test: # The name of the service.
       component: fc  # The name of the component.
       props: # The attribute value of the component.
         region: cn-shanghai
         service:
           name: fctest
           description: 'test'
           internetAccess: true
         function:
           name: emoji
           description: this is a emoji
           runtime: nodejs14
           codeUri: ./
           handler: index.handler
           memorySize: 128
           timeout: 6

3. Add the package.json file.

   The following sample code provides an example of the file:

   {
     "dependencies": {
       "node-emoji": "^1.11.0"
     }
   }

4. Run sudo s build --use-docker to install dependencies.

   After the execution is complete, the .s directory is generated in the mycode directory, and the dependencies are installed in the .s/build/artifacts/{serviceName}/{functionName} directory.

5. Run sudo s deploy to deploy the project.

   After the execution, you can deploy functions to Function Compute.
