💻 Code

This is the same code as given in the example of Typescript compiler api

import * as ts from "typescript";

const source = "let x: string  = 'string'";

let result = ts.transpileModule(source, { compilerOptions: { module: ts.ModuleKind.CommonJS }});

console.log(JSON.stringify(result));

🙁 Actual behavior

An error occurred, saying that ts.Modulekind is undefined

let result = ts.transpileModule(source, { compilerOptions: { module: ts.ModuleKind.CommonJS }});
                                                                                   ^

    at async Object.loadESM (internal/process/esm_loader.js:68:5)

🙂 Expected behavior

The result should've been printed

Ok, I replaced ts.Modulekind.CommonJS to 1, then i received a new error

let result = ts.transpileModule(source, { compilerOptions: { module: 1 }});
                ^

TypeError: ts.transpileModule is not a function

so I thought there is something wrong with my import statemenet
so i changed it to

import ts from "typescript"
// earlier was: import * as ts ...

and it worked, but still in Compiler API Wiki example it used import * as ts ... maybe its outdated?

The is a duplicate of #56366.

That code only works when in a TS file such that import helpers are in use. In native ESM in Node, you must write:

import ts from "typescript";

At some point, a namespace import used to cause Node to throw, but that is no longer true and I'm not sure why. Potentially we could update the wiki to use the default import for safety as that should work elsewhere.

it didn't work in the typescript file either

Do you have esModuleInterop enabled?
