• What you expected to happen

Works.

Config

import {join} from 'path'
import fs from 'fs'
import {resolve} from 'import-meta-resolve'

export default (overrides = {}) =>
  async ({projectDir}) => {
    console.log('Ava using project dir:', projectDir)

    const loaderStr = await resolve(
      '@live/esm-loader/index.js',
      import.meta.url,
    )

    const config = {
      verbose: true,
      extensions: {
        ts: 'module',
      },
      nonSemVerExperiments: {
        //nextGenConfig: true,
        //configurableModuleFormat: true,
      },
      nodeArguments: [
        '--no-warnings',
        `--experimental-loader=${loaderStr}`,
        '--conditions=transpile',
        '--experimental-specifier-resolution=node',
        '--experimental-import-meta-resolve',
      ],
      files: [
        '**/*.test.ava.ts',
        '!**/node_modules/**', // I think this is ignored by default. Maybe not needed here.
        '!.dev/**', // This was needed otherwise we get some `ENAMETOOLONG` error. Probably from circular symlinks or something.
      ],
      ignoredByWatcher: ['.dev'],
      ...overrides,
    }

    return config
  }

So '--experimental-specifier-resolution=node' was causing this error.

Although its also caused by '--loader=ts-node/esm'.

I don't understand how this is suppose to work. When require(base) is called, the async run is kicked off which sets the getRunner export. So getRunner will not be set by the time the module is returned.

main.js

const runner = require('./base').getRunner();
module.exports = runner.chain;

base.js

async run = () => {
...
    let accessedRunner = false;
    exports.getRunner = () => {
        accessedRunner = true;
        return runner;
    };
...
}

if (isRunningInThread) {
    const {workerData} = require('worker_threads');
    const {options} = workerData;
    delete workerData.options; // Don't allow user code access.
    run(options).catch(onError);
} else if (isRunningInChildProcess) {
    channel.send({type: 'ready-for-options'});
    channel.options.then(run).catch(onError); // eslint-disable-line promise/prefer-await-to-then
}

Also, I dont get the chalkOptions error when using ava --no-worker-threads.

I think I found my issue. I am using pnpm and two different versions of ava are being used - a global one and a local one. I've seen this elsewhere with workers. It depends on how the path to the worker script is being resolved.

So when ava is invoked globally, it invokes its workers locally when using pnpm...I think.

AVA 4 no longer wants to be installed globally, see the discussion in https://github.com/avajs/ava/commit/1ee1e82678a9a2024d2635a9adeb8f14d98669f8.

pnpm exec ava should work.
