Updated to latest release causes compiler errors.

[niemyjski]

I just updated to rc3 and I'm seeing the following starting to occur in my project with the latest webpack 3 + rc3 plugin.

Is this a known issue?

ERROR in [at-loader] ./node_modules/aurelia-webpack-plugin/dist/types/AureliaDependenciesPlugin.d.ts:4:29 
webpack: Failed to compile.

I am getting the same.

[Miklet]

I have also just updated to the newest rc version and got other compile error when using ModuleConcatenationPlugin:
Error: Can't figure out a normalized module name for undefined, please call PLATFORM.moduleName() somewhere to help.

Seems like I get this error when requesting \\node_modules\\aurelia-validation\\dist\\native-modules\\validate-binding-behavior.js' from aurelia-validation.

[Robula]

Similar issues here.

Cannot find namespace 'Webpack'.
Cannot find name 'DependencyOptionsEx'.

Rolled back to RC2 in the meantime.
Thank you

[vincentw56]

Funny thing is I haven't had any issues with it. I mean I get the errors, but it still works fine. At least for me, everything still works as expected.

[jods4]

Those errors don't impact runtime, it's just bad TS definitions apparently.

Do you guys use a Typescript webpack.config.ts?

Or does it really come from your app compilation? If so, that's rather strange because the .d.ts in question are for compile-time components. They shouldn't be picked up by your build.

I notice at-loader (awesome TS loader) in the original issue. Is it relevant or is it the same with ts-loader?

@Miklet that's unrelated, please open another issue. Aurelia webpack plugin RC3 should have brought compatibility with ModuleConcatenationPlugin, are you sure you're not using the RC2 bits?

[jods4]

I received a repro.

It used awesome TS loader but the error went away when I switched to ts-loader.

I'm not too familiar with at-loader, I'll dig the docs later.
For some reason it includes in the compilation .d.ts files that should not be included (it's the type defs for the compile-time plugin).

[vincentw56]

I use at-loader. It is during the build process and not from the webpack.config file. Here is a list of my errors:

[Vheissu]

Another at-loader user here and experiencing the same issue as above from @vincentw56

[Vheissu]

I can confirm using ts-loader fixes the issue. The main issue however, is the official Webpack TypeScript skeleton uses Awesome TypeScript Loader which is probably the reason this is affecting people. Do we fix the issue with ATS or just move the skeletons (which will be sunset soon anyway) to ts loader?

[vincentw56]

Is ts-loader better than at-loader? From what I've seen, at-loader is faster. Maybe that has changed.

[Robula]

I was also using at-loader along with a webpack.config.ts file.

[jods4]

@Vheissu I'd like to try to figure out why at-loader behaves this way and if it can be fixed before changing the skeletons.
Haven't had the time to so far :(

[vincentw56]

I tried switching to ts-loader, but that just caused a bunch of other errors. Plus, ts-loader is so much slower than at-loader.

[JeroenVinke]

We've just hit this in the CLI. aurelia/cli#700 (comment) is a good solution until we can figure out what's going on

[JeroenVinke]

I may have some clues.

The webpack typescript definition has import statements, which makes it a module: microsoft/TypeScript#5506 (comment). So you need to import it before using it.

The typescript definitions of the webpack plugin doesn't do this: https://github.com/aurelia/webpack-plugin/blob/master/dist/types/AureliaPlugin.d.ts#L27-L28. This wasn't a problem until this change that adds the typings file to package.json.

[jods4]

We found that removing typings from project.json works around the issue, i.e. at-loader does not include those definitions in the compilation anymore.

We'll publish this work-around until a better solution is found, I opened s-panferov/awesome-typescript-loader#484.

If you used those definition to build webpack.config.js from TS sources, you'll need to import them manually until the work-around is reversed.

[jods4]

A few months later... clarifying the status of this open issue:

• the issue occurs no more because of published work-around above. It would be nice to bring back typings but it's not critical.
• the issue at awesome-typescript-loader has gotten zero reply 😞

[jods4]

I'm closing this as we worked-around the issue by removing typings.

#143 tracks adding them back, but I'm not sure if/when it's gonna happen, given the lack of support from awesome-typescript-loader.
