Upgrade AWS Lambda Node.js version

AWS has announced the end of support for Node.js 10.x. Hence, I have to upgrade our existing Node.js 10.x Lambda functions to 14.x.

In this post, I will share my changes on CI/CD and SAM scripts:

  • CodeBuild project Docker image

    • old: aws/codebuild/nodejs:10.1.0 identifier
    • new: aws/codebuild/standard:5.0 identifier 
      AWSTemplateFormatVersion: 2010-09-09
Description: My CI/CD

Parameters:
ServiceName:
    Type: String
    Default: my-api          
BuildImageName:
    Description: Docker image for application build
    Type: String
    Default: aws/codebuild/nodejs:10.1.0
CodeBuildProject:
    Type: AWS::CodeBuild::Project
    Properties:
        Environment:
            Type: LINUX_CONTAINER
            ComputeType: BUILD_GENERAL1_SMALL

  • Lambda Node.js runtime version

    • old: Node.js 10 (nodejs14.x identifier )
    • new: Node.js 14 (nodejs10.x identifier ) 
      SAM template.yaml
      Transform: AWS::Serverless-2016-10-31

  • Node Oracle DB package

    • old: 3.1.2
    • new: 5.2.0 Use node-oracledb 5.2 to connect Node.js 12, or later, to Oracle Database. Older versions of node-oracledb may work with older versions of Node.js.
      package.json
      {
"name": "accommodation",
"version": "1.0.0",
"description": "",
"dependencies": {
    "aws-sdk": "^2.501.0",
    "axios": "^0.21.1",
    "oracledb": "^5.2.0"
},
"devDependencies": {},
"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
},
"author": "Fairtech",
"license": "ISC"
}

  • CodeBuild buildspec.yaml
    Add command to install Node.js 14.17.3

    buildspec.yaml
    version: 0.2

phases:
pre_build:
    commands:
    - echo "Installing node"
    - n 14.17.3

  • Last, trigger the CI/CD to deploy all Lambda functions:

    All functions are using Node.js 14.x now.
