Notes

• Update the code as needed and document what you have done in the readme below
• Will be nice if you can git tag the tasks by number

Solution

• Used method-override middleware in order to use PUT HTTP verb to edit item.
• Used docker and docker-compose to containerized deployment.
• Used mocha, chai, and supertest for testing.
• Used istanbul to display test coverage.
• Used sanitizer module to mitigate the XSS vulnerability.
• Added Helm Chart.
