Dynamic imports don't work even with jsc.parser.dynamicImport set to true

[mgol]

Describe the bug

Dynamic imports don't work even with jsc.parser.dynamicImport set to true. Meanwhile, the script below prints:

$ node ../../_swc-run.js 
error: import(...) expressions requires `jsc.parser.dynamicImport` to be true
 --> /Users/myuser/test.ts:1:38
  |
1 | export const importSomething = () => import('lodash');
  |                                      ^^^^^^

/Users/myuser/project/node_modules/@swc/core/index.js:116
        return bindings.transformSync(isModule ? JSON.stringify(src) : src, isModule, toBuffer(options));
                        ^

Error: GenericFailure: failed to process js file

Input code

Save the following contents as /Users/myuser/test.ts (or any other path as long as you update it in the script as well):

export const importSomething = () => import('lodash');

and run the following code:

'use strict';

const fs = require('fs');
const swc = require('@swc/core');

const filePath = '/Users/myuser/test.ts';

const programmaticOptions = {
  jsc: {
    parser: {
      syntax: 'typescript',
      tsx: true,
      jsx: true,
      dynamicImport: true,
    },
    target: 'es2015',
  },
  sourceMaps: false,
  filename: filePath,
  sourceFileName: filePath,
};

const source = fs.readFileSync(filePath, 'utf-8');
const output = swc.transformSync(source, programmaticOptions);

console.log('output', output);

Config
Config is embedded in the script above.

Expected behavior
The code should compile.

Version
The version of @swc/core: 1.2.40

Additional context
Add any other context about the problem here.

You should remove jsx: true.

Anyway, this should be error... But it will be fixed by #1244.

Am still running into this using the swc-loader with @swc/[email protected] not sure if I should've made an issue there or just here since this seems related. Tried different parser options but didn't find a working combination.

@traverse Can you show me your config?

[traverse]

@kdy1 The config I was using is as follow

{
  loader: 'swc-loader',
  options: {
    jsc: {
      target: 'es2015',
      parser: {
        syntax: 'typescript',
        tsx: true,
        dynamicImport: true,
        classProperty: true,
        exportNamespaceFrom: true,
        exportDefaultFrom: true
      }
    }
  }
}

Like I said it's using Webpack with the swc-loader but I'd expect the config to be the same.

[kdy1]

@traverse I guess you should remove

        classProperty: true,
        exportNamespaceFrom: true,
        exportDefaultFrom: true

Seems like a bug of napi-rs.

I've tried several configurations also without those properties but it still kept showing the same error, I'll see if I can reproduce it again tomorrow.

Same here.
