Oops! Unable to locate the module specifier "highlight.js" in the ES6 module compiled from TypeScript

I'm currently experimenting with the highlight.js library for code highlighting, and while it does support ES modules, I encountered an issue when trying to use it in an ES6 module compiled from TypeScript. The error message that pops up is:

Uncaught TypeError: Failed to resolve module specifier "highlight.js". Relative references must start with either "/", "./", or "../".
Despite having installed @types/highlight.js and highlight.js itself via NPM.

highlight.ts

import hljs from "highlight.js";

hljs.highlightAll();

tsconfig.json

{
    "compilerOptions": {
        "target": "ES2022",
        "module": "CommonJS",
        "esModuleInterop": true,
        "forceConsistentCasingInFileNames": true,
        "strict": true,
        "skipLibCheck": true,
        "outDir": "js",
        "rootDir": "ts",
        "moduleResolution": "node",
        "baseUrl": ".",
        "paths": {
            "highlight.js": ["/node_modules/@types/highlight.js"]
        }
    }
}

In my attempt to resolve this issue, I tried implementing an importmap as shown below, only to be met with a new error:

Uncaught SyntaxError: The requested module '../lib/core.js' does not provide an export named 'default'

<script type="importmap">
   { 
      "imports": {
        "highlight.js": "/node_modules/highlight.js/es/core.js"
      } 
   }
</script>

I also experimented by changing the module setting in tsconfig.json to CommonJS, which led to yet another error:

Uncaught ReferenceError: export is not defined
. This was eventually resolved by adding
<script>var exports = {};</script>
to the DOM. However, a subsequent error surfaced:
Uncaught ReferenceError: require is not defined
, despite not utilizing require anywhere in my code.

I am seeking a resolution that avoids using tools like Webpack.

Answer №2

Here's a quick yet unconventional fix. I employed a script tag to fetch highlight.min.js, then simply disregarded any code in the highlight.ts file by using @ts-ignore.
