Have you recently felt your react codebase has become unmanageable and produces an exponential amount of bugs? If yes, using React as a standalone library might be the root of the problem. React codebase tends to expand quickly in the long run, making it harder for developers to maintain accuracy in the long run. One of the alternatives for building a sustainable codebase in React is to combine it with efficient programming languages such as Typescript.

Typescript is an open-source and type-centric programming language that is becoming increasingly popular amongst web developers and software engineers. As an improvement to the existing JavaScript language, Typescript has been designed to make development easier, faster, and more efficient. This functionality allows developers to write less repetitious, shorter, and reusable code. In this article, we will learn about advanced TypeScript types built from existing types to allow for code reuse.

In the previous part of this series, we optimized our Lambda function. However, our API is open to the public — anyone with the URL can use it and get a response. In this take, we are going to secure our API using a tool called Amazon Cognito. This will only allow authenticated users access to our endpoints. Ready? Let’s go!

Serverless computing is an exciting alternative to hosting apps on the AWS cloud. In this four-part series, we’ll run through how to build AWS Lambdas with TypeScript, improve the dev experience, optimize it, and finally, use AWS Cognito for security. In this take, I would like to take you on a journey to explore AWS Lambdas using TypeScript. We will build a pizza API, use Claudia to help deploy the app, and use the AWS CLI tool to set up a DynamoDB database.

Developing against third-party or unfamiliar web APIs can be painful and slow compared to using native libraries. For example, making requests with an HTTP client is simple enough but offers no compile-time sanity checks and no way for code suggestion tools like Intellisense to help you navigate. Worst of all, if the API you are consuming introduces breaking changes, you won’t find out until runtime.
