Having issues with property decorators

[arimus]

I'm having an issue where it seems the decorator is called when the class is initiated, but any object property defines, etc. all seem to be ignored / value never set, or getters never executed. Everything works property with tsc compilation, but not with tsup. I do have @swc/core installed.

Any thoughts?

tsconfig.json

{
  "compilerOptions": {
    "rootDir": "src",
    "outDir": "dist",
    "target": "ES2022",
    "module": "ESNext",
    "types": ["reflect-metadata", "mocha", "node"],
    "lib": ["ES2022", "dom"],
    "moduleResolution": "node",
    "declaration": true,
    "declarationMap": true,
    "sourceMap": true,
    "strict": true,
    "pretty": true,
    "importHelpers": true,
    "allowJs": true,
    "composite": false,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "useDefineForClassFields": true,

    "resolveJsonModule": true,

    "strictPropertyInitialization": false,
    "noImplicitAny": false,
    "noImplicitThis": false,

    "useUnknownInCatchVariables": false,
    "alwaysStrict": true
  },
  "include": ["src/**/*.ts", "test/**/*.ts"],
  "exclude": ["coverage", "node_modules", "dist"]

}

tsup.config.ts

import { defineConfig } from 'tsup';

export default defineConfig({
  entry: ['src/index.ts'],
  format: ['cjs'],
  dts: true, // Generates TypeScript declaration files
  sourcemap: true,
  clean: true,
  tsconfig: './tsconfig.json', // Make sure this points to the right tsconfig
  esbuildOptions(options) {
    options.tsconfig = 'tsconfig.json'; // Ensure tsconfig is respected
    options.target = 'es2022'; // Target ES2020 or your preferred version
    options.platform = 'node';
  },
});

I'm having the same problem. Did you find any solution?

Unfortunately no, I gave up. I ended up with rollup and @rollup/plugin-typescript which works well.
