COVID-19 Dashboard

This is for fun :)

Prerequisites

• NodeJS

Install

yarn install --frozen-lockfile

Start for development

yarn start:dev

Runs the app in the development mode. Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits. You will also see any lint errors in the console.

Test the project

yarn test

Launches the test runner in the interactive watch mode. See the section about running tests for more information.

Test the project on CI

yarn test:ci

It will force to test all test cases and then quit once completed

Build the production bundle

yarn build

Builds the app for production to the build folder. It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes. Your app is ready to be deployed!

See the section about deployment for more information.

run the production bundle

start:prod

You have to build the production bundle first

Demo

Please visit the dashboard here

Remarks:

• The data (COVID-19 data) is from WHO

• As the WHO restricts its data by using CORS, I used a proxy server to bypass the CORS

• The country information is from REST Countries

• The UI is powered by React and PrimeReact

Deployment

Prerequisites

• AWS CLI 2+

• Serverless 2+

Pre deployment (create cert)

As creat cert takes very long time, so, we should create the cert before everything Besides, we have to create the cert in us-east-1

1. run aws --region us-east-1 cloudformation create-stack --stack-name create-covid-19-dashboard-cert --template-body file://deployment/create-cert.yml --tags Key=project,Value=covid-19

2. Go to AWS cert manager page and validate the cert (add CNAME record in Route53)

3. wait for the validation to be completed

4. capture the ARN in the cloudformation stack output

Deploy infrastructure

we could run the serverless deployment to deploy the infrastructure

• run serverless deploy --stage prod --certArn {cert arn captured from above}

Deploy application

Most of the time we only need to deploy the application once the infrastructure is created

• run serverless client deploy --no-confirm --no-config-change --no-policy-change -no-cors-change
