Upon updating the file extension from js to ts, Ionic is no longer able to locate the module

I have been using the Ionic framework to develop a mobile application by following the guidance provided at http://ionicframework.com/docs/v2/getting-started/tutorial/.

ionic start my-mobileapp sidemenu --v2

After that, I launched the app in a browser using the command below.

ionic serve

Everything was working smoothly until I decided to change my file extensions from *.js to *.ts.

Error: Cannot find module './pages/getting-started/getting-started' from '/Users/jwayne/git/my-mobileapp/app'

Surprisingly, switching back the file extensions to js resolved the issue.

My query is regarding how Ionic can differentiate between TypeScript and JavaScript code stored in a .js file?

Answer №1

It is my recommendation that you enter the following command...

ionic start my-mobileapp sidemenu --v2 --ts

Answer №2

To embark on a Typescript journey, kickstart your project with the --ts flag, as mentioned previously. Next, gradually transition parts of your code to adhere to Typescript standards.

For a brief comparison between Javascript (ECMA6) and Typescript, check out this informative link:

If your project isn't too convoluted at the moment, it's strongly advisable to heed the guide and make the switch to Typescript.
