Upgrading to 3.0.2 : Errors in previously 'clean' build

[roddypratt]

I've been using 2.3.7 for a while without issues. Upgraded to 3.0.2, and suddenly I see loads of errors in the build.

Most are JQuery related, like

ERROR in ./src/buttonbus.ts
[tsl] ERROR in C:\WebCentre\src\buttonbus.ts(30,11)
      TS2304: Cannot find name 'JQuery'.

I'm using TS 2.5.3, Webpack 3.7.1

Webpack.js has this snippet

      {
        test: /\.ts$/,
        loader: 'ts-loader',
        options: {
            logLevel: "info"
          }
      },

... and my tsconfig.json looks like this.

{
  "compileOnsave": true,
  "compilerOptions": {
    "module": "es6",
    "removeComments": true,
    "outDir": "js_out",
    "allowJs": true,
    "sourceMap": true,
    "noImplicitAny" : false,
    "noUnusedLocals": false,
    "noImplicitReturns": true,
    "noImplicitThis": true,
    "forceConsistentCasingInFileNames": true,
    "target": "es6",
    "types" : ["fb", "gapi.youtube"]
  },
  "include": [ "src/*.ts" ]
}

Any suggestions welcome. I appreciate there's a big change to V3 but I can't see anything relevant in the options that I'd need to adjust?

Do you want to try adding entryFileCannotBeJs: true as an option? That's the only thing that occurs...

[johnnyreilly]

Would you be able to supply a minimal reproduction of the issue if that doesn't work? I'm really keen not to break people's projects. It's a breaking changes release but I was anticipating that most of the breaking changes wouldn't affect anyone. I've had some publishing issues with npm today so I'm trying to isolate the problem

[roddypratt]

Thanks! entryFileCannotBeJs: true fixes it. (Also, removing the allowJs:true from my tsconfig.json works - I'm not actually sure why that was there in the first place...)

[johnnyreilly]

Great! Would you still be able to supply me with a minimal repro of the issue?. I think what you've stumbled on is a bug in ts-loader that I'd like to fix. But without being able to reproduce it, I can't!

[roddypratt]

Sure. I'll see what I can do...

[johnnyreilly]

Thanks - I appreciate it

[roddypratt]

@johnnyreilly Fairly minimal example here. Better late than never...

Hopefully this will back up that this is a dupe of 657.

[johnnyreilly]

Thanks @roddypratt - I'll use it to double check.

[johnnyreilly]

Looking good so far - hopefully v3.0.3 of ts-loader will remove the need to use entryFileCannotBeJs: true

Fix released with 3.0.3

Verified fixed!
