Error encountered when importing a function in Typescript causes a compiler issue

When working with Typescript, I am utilizing the import function following the instructions provided at:

https://github.com/Microsoft/TypeScript/issues/12933

My implementation looks like this:

 import("../myScriptToBeImported").then((module) => {
                this.dosomethingWithModule(module);
            }).catch(this.doSomethingWithError.bind(this));

I am integrating this into an MVC project in Visual Studio with Webpack. Even though Webpack successfully compiles the Typescript and the project runs smoothly, Visual Studio constantly displays the following errors for the code above:

  • TS1128 (TS) Declaration or statement expected.
  • TS2391 (TS) Function implementation is missing or not immediately following the declaration.
  • TS7010 (TS) 'import', which lacks return-type annotation, implicitly has an 'any' return type.

The version of Typescript being used is 2.4.2. How can these errors be resolved?

In case it helps, here is a look at my tsconfig file:

{
  "compilerOptions": {
    "module": "esnext",
    "moduleResolution": "node",
    "noEmitOnError": true,
    "strict": true,
    "removeComments": false,
    "sourceMap": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [ "es6", "dom" ],
    "baseUrl": ".",
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true
  },
  "exclude": [
    "node_modules",
    "wwwroot"
  ],
  "compileOnSave": false,
  "buildOnSave": false
}

Using function-style import is not currently supported in the JavaScript module specification. To enable it, you must update your tsconfig.json file and set module to "esnext".

If you have already made this change and are still experiencing issues, it could be related to your Visual Studio configuration. Ensure that your project is set up to use the correct version of the TypeScript compiler.
