不使用 es6 语法无法导入 Chessjs

Question

In all of the chessjs documentation, const chess = require('chess'); is used.

However, when I try to use this syntax, I get this error:

const Chess = require('chess');
              ^

Error [ERR_REQUIRE_ESM]: require() of ES Module is not supported.
Instead change the require of main.js to a dynamic import() which is available in all CommonJS modules.
    at Object.<anonymous> {
  code: 'ERR_REQUIRE_ESM'
}

Is there a solution for this?

Answer 1

The dynamic import() looks like this

async function loader(){
  const Chess = await import('chess')
  // things with Chess
}

As Evert mentioned, this can also cover the conditional import in an ESModule

Answer 2

Although this isn't the solution to the general question (which is why I'm not marking this as the solution), I ended up just migrating away from the module chess which doesn't allow commonjs requires to the module chess.js which allows both.

New code:

const { Chess }= require('chess.js');
