Deployment on AWS Lambda

Introduction

This document describes how to deploy Code Metrics on AWS Lambda.

Prerequisites

• AWS CLI
• Node.js 20.x or later

Deployment

The AWS Lambda deployment can be found on the Releases page.

Download the codemetrics-api.zip file. See the example template.yaml for an example of how to deploy the Lambda function.

The frontend web UI is a static site, so can be hosted anywhere. You can find the latest version of the web UI on the Releases page.

Download the codemetrics-ui.zip file and host it on a static site. You will need to set the apiBaseUrl variable in config.json to point to the API endpoint.

Example

Infrastructure and backend

Change directory to the codemetrics-api directory:

cd backend/lambda

Deploy bucket and CloudFront distribution:

sam deploy

Frontend

Set apiBaseUrl in config.json to the API base URL.

Deploy static web assets:

aws s3 sync dist/ s3://<bucket-name>/
