ESLint integration fail

[ivanbanov]

Im in the process of migrating a codemod from jscodeshift to putout so I can integrate it with ESLint and properly test it.

Unfortunately Im facing the following error in a minimal setup:

> eslint index.ts

Oops! Something went wrong! :(

ESLint: 8.57.0

Error: Key "rules": Key "no-debugger": create(context) {
            const {options} = context;
            const prepared = prepare(plugin, context, ...<omitted>... } could not be cloned.

What am I doing wrong? Is it a bug?

I have no access to repository, show me ESLint config you are using.

oh sorry, I made it private for no reason, it's public now

You need to update ESLint to v9, and fix config.

Try something like this:

module.exports = [
  {
    files: ['*.ts'],
    languageOptions: {
      parser,
      parserOptions: {
        project: true,
      },
    },
    plugins: {
      '@typescript-eslint': tseslintPlugin,
      'poc': {
        rules: {
            'no-debuger': createPlugin(require('./.putout/no-debugger.js')),
        },
    },
    rules: {
      'poc/no-debugger': 'error'
    }
  }
]

Declare poc in plugins section and use it in rules.

nice! thanks for spotting the issue in the config. it worked, even with v8 :)
