Possibility to support vue-loader?

[HerringtonDarkholme]

Thanks for building ts-loader for webpack! I wonder whether ts-loader can support vue.js' single file component.

Related issue in vue-loader
vuejs/vue-loader#109

The current problem is ts-loader cannot resolve files with extension name .vue. However, TypeScript compiler supports customizing module resolution.

Since ts-loader has already implemented a custom resolveModuleNames function, supporting it is feasible.

I tried locally and it works. However I'm a newbie to webpack and I think my try is dirty and hacky...

Do you have any good ideas? I'm happy to implement them.

I forked ts-loader for this. But it seems ts-loader changes quite fast. Any possibility to support vue natively in ts-loader?

[johnnyreilly]

Quite possibly. I'm just doing a bit of a refactor on the code to get it to a more maintainable place. I'd be interested in getting vue support in once that's done. (I'm currently guessing I'll be done with the refactor inside a week or 2).

Does adding vue to your webpack.config not resolve the issue?:

 resolve: {
    extensions: ['', '.ts', '.tsx', '.js', 'vue']

Forgive me if that's a naïve question; I have 0 vue experience....

It still need some special handling in loader, but rather small modification.

The core modification is appending .ts suffix to *.vue file, then every thing is fine. My concern is its hard coding nature.

[johnnyreilly]

I'm on my phone and so can't really look at this properly. But I think we can avoid hard coding and just add another option. As I see it

function appendSuffixToVue(fileName: string) {
    if (/\.vue$/.test(fileName)) {
        return fileName + '.ts';
    }
    return fileName;
}

Is something that tests a file path ends with vue and if so suffixes .ts on the end. So what say we introduce a ts-loader option called appendTsSuffixTo that, when supplied, is used to suffix .ts in the manner your fork does. Sound good?

[HerringtonDarkholme]

That's great. More generic. 👍

[johnnyreilly]

Great - we'll need an integration test to cover this. You may already have one we can use. We've recently introduced "execution tests" as well as the pre-existing "comparison tests". Either will do. The comparison tests only run against the latest released version of TypeScript. The execution tests against all versions back to 1.6.

I will submit a pull request once refactor is done. Looking forward to your refactor :)

[johnnyreilly]

Cool! The refactor is basically done. Just waiting on some feedback. Will let you know when I merge 😄
