Comparing the process of transpiling Typescript in the browser to pre-compiling JS files

After extensive searches, I have not been able to find any information on this specific topic. In my Typescript Angular 2 application, I have configured my tooling to compile .ts files into JavaScript locally and then serve them to the browser.

Recently, I discovered that by including typescript.js and making some adjustments to System.config, I can skip compiling the .ts files locally and have transpilation occur in the browser at runtime.

My main concern is whether in-browser transpilation poses a performance issue as my application grows larger. It seems logical to believe so, but I am seeking feedback from those with experience using this setup.

Answer №1

Utilizing browser compilation is beneficial when developing a Plunker or similar project, however, for optimal production results it is recommended to transpile before deployment. In-browser transpilation may result in decreased performance, larger download sizes, and longer loading times.

Answer №2

Given the widespread support for ES6 in various browsers, wouldn't it be logical to perform transpilation directly within the browsers? This way, only the unsupported features will need to be transpiled.
