Integrate TypeScript into the current project

As a newcomer to Typescript, I am currently exploring the option of integrating it into my current project.

In our MVC project, we have a single file that houses the definitions of all model objects. This file is downloaded to the client when the user first visits the page. If the user clicks on a button for a specific feature, only the relevant View/UI files are downloaded on demand to enhance responsiveness.

I have successfully converted all my model objects to Typescript objects and generated an output file similar to the existing one. Now, I am faced with the task of creating view files that contain only the logic related to views. However, when I import model objects in these view files, it also includes the definition of the model objects in the output js file, which in turn increases the file size.

My question is: Is there a way to reference model objects in view files without importing them since the model file is already downloaded to the client before the view files?

Answer №1

Many bundlers break up files based on dynamic imports. When you call import as a function, that is considered a dynamic import.

import('./myViewFile')

When the bundler encounters a dynamic import, it will try to separate related code into different files during compilation so that they can be requested independently when needed.

However, how you utilize these dynamic imports will vary depending on the frontend framework you are using.

In React, for example, it would look something like this:

const OtherComponent = React.lazy(() => import('./OtherComponent'));

(Refer to the React documentation on code splitting here: https://reactjs.org/docs/code-splitting.html)

The implementation of dynamic imports in your code will depend on various factors, but the approach mentioned here is commonly used in frontend development. This answer should at least provide you with the necessary keywords to research further.
