vue-loader 14.1.0 ignores transformToRequire config

[andreyrd]

Version

14.1.0

Reproduction link

https://github.com/andreyrd/vue-loader-transformtorequire-demo

Steps to reproduce

1. Clone the repo.
2. Run yarn install to install the project with vue-loader: 14.0.0.
3. Run yarn dev and note that there are two Vue logos showing up, one after the other.
4. Stop the server.
5. Edit the package.json and update vue-loader to 14.1.0.
6. Run yarn install to install vue-loader: 14.1.0.
7. Run yarn dev and note that the second Vue logo no longer shows up.

What is expected?

The second image should be showing up.
The second image is a custom component that relies on the transformToRequire config to have Test: 'source' in order to transform it's source prop into a require() statement.

See build/vue-loader.conf.js for the config I'm talking about.

What is actually happening?

Since 14.1.0, vue-loader is ignoring the transformToRequire property in the config.

yes, today I also found this issue after upgrading vue-loader.
It can be fixed by changing https://github.com/vuejs/vue-loader/blob/master/lib/template-compiler/index.js#L17 to

const defaultModules = [transformRequire(vueOptions.transformToRequire), transformSrcset()]
