What is TypeScript?
- To eliminate inaccuracies, it is necessary to manually check the types and syntactic correctness of the code. This lengthens development time and extends the delivery cycle to production, which increases development costs.
- Prolonged onboarding of new developers can result, as developers must determine the properties of the structures they are working with, as well as the data types. Although JSDoc can be used to document code and annotate types, there is still a need to synchronize the actual code and documentation. Lack of synchronization, in turn, can mislead developers and make it difficult to introduce new features requested by the business.
The TypeScript advantage
TypeScript also helps developers quickly understand the purpose of a variable in code. It can also suggest properties available in functions, classes or components. Being able to quickly find a variable is important because it reduces the likelihood of calling the wrong function or accidentally skipping a variable declaration. Any reduction in bugs and errors reduces the time it takes to resolve these issues and, therefore, reduces overall development time. This gives developers more time to work on the logic of the application and correct errors that can adversely affect the performance and usability of the application. According to a post mortem analysis of Airbnb, 38% of the bugs they encountered were preventable with TypeScript after the company adopted it across the organization.
As a static language, TypeScript performs compile-time type checks, reports type errors, and helps developers spot errors early in development. Reducing errors when working with large code bases can save development hours.
Clear, readable code is easy to maintain, even for newly integrated developers. Since TypeScript calls for type assignment, code instantly becomes easier to use and understand. In essence, TypeScript code is self-documenting, allowing distributed teams to work much more efficiently. Teams (and individual developers) don’t have to spend inordinate amounts of time learning about a project.
TypeScript’s integration with editors also makes it easier to validate code with contextual suggestions. TypeScript can determine which methods and properties can be assigned to specific objects, and these suggestions tend to increase developer productivity.
TypeScript is widely used to automate the deployment of CI / CD infrastructure and pipelines for backend and web applications. In addition, the client part (for example, when using Angular) and the backend can be written in the same language, TypeScript. This flexibility allows an engineer who knows a programming language to cover all parts of the system.
The advantages of TypeScript have been noticed by developers. TypeScript was used by 78% of 2020 State of JS respondents, 93% of them saying they would use it again. TypeScript continues to gain popularity. It was voted the second most popular programming language in the Stack Overflow Developer Survey 2020.
TypeScript and AWS: Better Together
There is another compelling reason to consider TypeScript for large-scale application development projects. It is fully supported by AWS, the leading cloud platform for the design and development of modern applications, as discussed in Gartner Magic Quadrant for Cloud Infrastructure and Platform Services.
The following services and tools have a seamless out-of-the-box integration with TypeScript, allowing you to use this language for a variety of tasks:
- AWS CDK provides infrastructure-as-code (IaC) to automatically deploy the entire infrastructure with one click. You can also automate the creation of CI / CD pipelines for future launch of specific jobs on demand.
- AWS Lambda Allows you to run compute tasks in serverless mode using automatic scaling and an efficient pricing system.
- Amazon EC2, DHW and EKS can cover all your tasks and provide a wide range of solutions to run applications written in TypeScript, from bare metal servers to complex clusters of hundreds of Docker containers.
Optimize your application development projects
All decisions made during an application development project can impact overall costs and time to market. This involves using the right programming language and using the most appropriate platform and cloud resources.
When approaching an application development project, a one-size-fits-all approach rarely works. Take the time to define your needs and priorities and select the best resources for the best results.
