When I first started building websites in 2021, the decision to use JavaScript was an easy one – it was strong, well-documented, had a good community and seemed straightforward. I can recall many late nights debugging runtime errors that could’ve easily been picked up at compile-time, grappling with type coercion, and losing my mind trying to make consistent decisions in with large and growing code bases.

TypeScript interface definitions are critical in maintaining type safety when a JavaScript application is being created. They enable developers to define object structures and help ensure consistent development in a project. Understanding, using, and maintaining interfaces in TypeScript is important in proving to be beneficial to development regardless of project size – whether it is an enterprise application or a small JS app – giving you an experience and quality of code that will be superb.

With the release of Node.js v23.6.0, developers can now use TypeScript natively without additional transpilation tools like ts-node or manual compilation steps. This milestone significantly streamlines development workflows, simplifying build processes and improving the overall developer experience by reducing complexity.

Single-table design is a powerful approach to modeling data in DynamoDB because it allows you to store all your data in one place. This approach can simplify your data model and reduce the number of tables you need to manage. In the traditional approach, you create a separate table for each entity in your application. For example, you might have a table for characters and a table for quests. Each table would have its own primary key and attributes.

DynamoDB is a fully managed NoSQL database service provided by AWS. It is highly available, scalable, and a great fit for applications that need to handle large amounts of data with low latency. DynamoDB is a key-value document database, meaning that it is schema-less and can store any kind of data. It is also a serverless service, so you don’t have to worry about managing and scaling servers. In this take, we will model data in DynamoDB using TypeScript.

AWS Fargate is a serverless compute engine that allows you to run containers without managing servers. With Fargate, you no longer have to provision clusters of virtual machines to run ECS containers: this is all done for you. Fargate has an Amazon ECS construct that can host an API. In this take, we will build a Fargate service using the AWS CDK, put the API in a docker image, and then host it inside Amazon ECS. The API will be a pizza API and we'll store the data in a DynamoDB table.

The AWS Cloud Development Kit (CDK) lets you build serverless applications with the expressive power of a programming language like TypeScript. The CDK defines cloud infrastructure in code and deploys via AWS CloudFormation. In this post, we will build a Lambda function, an AWS Gateway API, and an S3 bucket to upload CSV files. The API will take requests in JSON and seamlessly convert them to CSV format. We will use the AWS CDK in TypeScript to reliably deploy our app through AWS CloudFormation. Ready?

With Node.js and Express, you can easily create a JavaScript server. Then the obvious question would be, “Why Typescript?” While JavaScript remains the most popular scripting language, TypeScript emerges as a great alternative when your application becomes more complex or when you collaborate with a distributed team of developers.

In this post, we'll explain what server-side rendering (SSR) is and how it's different from the usual way websites work. We will run you through how to use SSR with Next.js, React, and TypeScript step-by-step. By the end, you'll know how SSR can make websites faster and better.

Learning encryption and decryption in TypeScript involves understanding cryptographic concepts and utilizing cryptographic libraries to perform secure encryption and decryption operations. In the digital age, data security has become paramount. Protecting sensitive information from unauthorized access has led to the widespread use of encryption and decryption techniques.
