VS Code sees JavaScript files as if they were Typescript

I have recently delved into the world of Typescript and have been using it for a few days now. Everything seems to be working smoothly - Emmet, linting, etc. However, I've encountered an issue when trying to open my older JavaScript projects in VS Code. The editor is flagging warnings and errors related to typing and other TypeScript-specific features, even though I am working with JavaScript.

PS. I am currently working on a Vue (Nuxt) project where the Vetur Plugin handles syntax highlighting, linting, and more.

Here are some examples of the errors:

'modifyHtml' is declared but its value is never read.ts(6133)

Property '$store' does not exist on type 'CombinedVueInstance<Record<never, any> & Vue, object, object, object, Record<never, any>>'.Vetur(2339)

In addition, here is a snippet from my settings.js file:

{
  "workbench.iconTheme": "material-icon-theme",
  ...
  "json.schemas": []
}

Answer №1

After facing a similar issue, I spent some time troubleshooting and finally found the solution. If you want to turn off type-checking for JavaScript files, simply include checkJs: false in the compilerOptions section of your project's jsconfig.json file located in the root directory.

Below is an example of my jsconfig.json:

{
    "include": ["./src/**/*"],
    "compilerOptions": {
        "checkJs": false
    }
}

Answer №2

If you're encountering issues, consider disabling any tslint settings. This could potentially resolve the problem as similar errors can occur in eslint as well.

Answer №3

I have found success with the following configurations in my development environment. In my settings.json:

{
  "vetur.validation.interpolation": false
}

As for my jsonfig.json settings:

{
  "include": ["./src/**/*"]
}
