Overriding `tsconfig.json` for ts-node in mocha

Question

Is it possible to override which tsconfig.json ts-node uses when called from mocha?

My main tsconfig.json contains \"module\": \"es20

Answer 1

You can also use ts-mocha (https://www.npmjs.com/package/ts-mocha)

Example

package.json

"test": "ts-mocha -p test/tsconfig.cjs.json test/**/*.test.ts"

test/tsconfig.cjs.json

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "module": "commonjs"
  }
}
