What is the solution for addressing the deprecation warning "The 'importsNotUsedAsValues' flag will no longer work in TypeScript 5.5"?

Is anyone familiar with how to resolve this tsconfig error?

The flag 'importsNotUsedAsValues' is outdated and will no longer work in TypeScript 5.5. To address this error, use 'ignoreDeprecations: "5.0"' or switch to using 'verbatimModuleSyntax' instead.

I'm working with vscode and recently set up a new Vue project instance using Vite

Should I simply ignore this error or is there a specific solution for editing the tsconfig file?

Answer №1

Based on the information provided in the typescript verbatimModuleSyntax documentation, instead of using

"importsNotUsedAsValues": "error"

You should opt for

"verbatimModuleSyntax": true

For more detailed insights, take a look at the pull request.

Answer №2

Encountered a similar issue and was able to resolve it by following this workaround provided in the GitHub problem thread:

If you happen to be utilizing @vue/tsconfig/tsconfig.web.json or something of the sort, you can reset those properties causing errors when enabling verbatimModuleSyntax.

{
  "extends": "@vue/tsconfig/tsconfig.web.json",
  "compilerOptions": {
    // workaround for https://github.com/vuejs/tsconfig/issues/6
    "preserveValueImports": false,
    "importsNotUsedAsValues": "remove",
    "verbatimModuleSyntax": true,
    // end workaround
  },
}

I noticed that you are using @vue/tsconfig/tsconfig.web.json.

Answer №3

To remove this alert, simply include the following command in the tsconfig.json file within your project:

{
  "compilerOptions": {
    "dismissWarnings": "4.0",
    ....
  }
}

Answer №4

After updating VS code, an issue started to arise even though I wasn't using typescript in my project. It appears that VS code is utilizing typescript 5. The solution proposed by MRAH involving adding ignoreDeprecations in the compilerOptions did resolve the problem for me.

If you are working with VScode and have typescript included in your project, make sure to click on the TS banner in your status bar:

Then, choose Switch Version and select the typescript version that matches your project workspace:

Answer №5

The connectivity issue I faced was due to network restrictions. Once I switched to private mode, everything ran smoothly.
