🍿 Serverless Movie Search Engine

A movie search engine that utilises Terraform for provisioning cloud resources and hosted on the AWS Cloud with AWS Lambda function and Amazon API Gateway stack.

Techstack

• Terraform is an open-source infrastructure as code software tool that provides a consistent CLI workflow to manage hundreds of cloud services.
• Typescript is an open-source language which builds on JavaScript, one of the world’s most used tools, by adding static type definitions.
• AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers, creating workload-aware cluster scaling logic, maintaining event integrations, or managing runtimes.
• Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale.

Prepare before deploy 🚀

Before going to deploy step, you need to request an ACM Public Cerfiticate, read the AWS docs for more details:

• Request a public certificate using the console

After that, you need to create API Gateway > Custom domain name with the ACM Public Certificate on the previous step, read the AWS Docs for more details:

• Setting up custom domain names for REST APIs

Deployment 🚀

• Run yarn lint to lint TS code using both ESLint and Prettier working together
• Run yarn script:build-dependency-layer this will run a bash script to zip up production dependencies and add them to the lamba as a layer
• Run yarn build to run TSC to compile TS code to plain JS
• Run yarn cleanup to remove generated files after deployment steps
• Run yarn tf:init to get aws provider plugin downloaded
• Run yarn tf:plan to see changes that will be made
• Run yarn tf:apply to actually make those changes to your provider
• Visit AWS and see all your services provisioned via terraform
• Run yarn tf:destroy to destroy all the services that were built

You can also simply call yarn deploy:all to both zip up an archive and provision the resources together. Similarly you could run yarn update:all to destroy all resources and re-provision them.
