This is an example on how to host SPA static websites in S3

The cdk.json file tells the CDK Toolkit how to execute the app.

Getting started

  • sudo npm install -g aws-cdk to install AWS CDK CLI
  • npm install to install all dependencies for the project
  • curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"; sudo installer -pkg ./AWSCLIV2.pkg -target / to install AWS CLI

Verifications

$ cdk --version
2.103.0 (build d0d7547)

$ aws --version
aws-cli/2.13.29 Python/3.11.6 Darwin/22.6.0 exe/x86_64 prompt/off

$ npx ts-node --version
v10.9.1

AWS account setup

  • Add .env file containing details around the account ID, which region to use, and the default gateway ID in the account's default VPC
ACCOUNT='your account number <123456789>'
REGION='your desired region <us-east-2>'
IGW='internet gateway ID <igw-12abcd45>'
  • Create a programmatic user under console to use its creds with aws-cli and configure it in CLI
$ aws configure
AWS Access Key ID [None]: A*****************7
AWS Secret Access Key [None]: R**************************************M
Default region name [None]: ap-southeast-2
Default output format [None]: json
  • Now, you should be able to run cdk diff
$ cdk diff
