Utilizing TypeScript browser types within a Blazor application: A guide

Recently, I delved into experimenting with TypeScript within Blazor and found myself wanting to access some data from the browser (the specific data is not important as this is a general issue).

While I don't have much experience with TypeScript (having only dabbled in JavaScript previously), my C# skills are quite solid. Given that TypeScript has types unlike JavaScript, I began to wonder if there were any pre-defined types in TypeScript that could be used in my project?

After consulting the Mozilla documentation, I came across this link: https://developer.mozilla.org/en-US/docs/Web/API/Document

Considering that the `document` object has numerous properties, I assumed that there must be a specific datatype in TypeScript for such objects. Isn't that the essence of this language - providing typings?

However, when I tried utilizing `document`, nothing noteworthy happened; the suggestions menu remained empty (in contrast to C#, where it would prompt me regarding imports or other necessary steps).

Therefore, my inquiry is whether TypeScript includes predefined types for these web-based objects and how I can integrate them into Blazor (potentially requiring third-party libraries to import)?

Answer №1

Typescript language primarily focuses on defining fundamental types such as boolean, string, number, enum, and more. Being a super-set of javascript, Typescript allows you to interact with the Document Object Model just like in regular javascript coding. It is important to note that all valid javascript code can also be used in Typescript.

If you encounter difficulties with code completion, it is likely due to environmental factors rather than any inherent flaw in the Typescript language itself.
