Bug: Issue with Run Command - Services Fail to Start #17
Description
Describe the bug
There is a bug related to the run command in the create-polyglot repository. When invoking the run command (e.g., create-polyglot dev), certain services may not start correctly or expected behavior is not observed, especially for Node and frontend services. The runDev function in bin/lib/dev.js and the runner logic in scripts/dev-basic.cjs handle the service startup, but issues can occur if required directories or files are missing, or if script definitions are not present in the service's package.json.
To Reproduce
Steps to reproduce the behavior:
- Initialize a polyglot workspace.
- Add a service (e.g., Node, Python, etc.).
- Run
create-polyglot devto start services locally. - Observe if any services fail to start or expected logs/errors occur (e.g., "No auto-runnable Node/Frontend services found.", missing
polyglot.json, or missingservices/directory).
Expected behavior
All specified services should start successfully and pass health checks, with logs indicating successful startup.

Additional context
Relevant code snippets:
export async function runDev({ docker=false } = {}) {
const cwd = process.cwd();
const configPath = path.join(cwd, 'polyglot.json');
if (!fs.existsSync(configPath)) {
console.error(chalk.red('polyglot.json not found. Run inside a generated workspace.'));
process.exit(1);
}
const cfg = JSON.parse(fs.readFileSync(configPath, 'utf-8'));
const servicesDir = path.join(cwd, 'services');
if (!fs.existsSync(servicesDir)) {
console.error(chalk.red('services/ directory not found.'));
process.exit(1);
}
// ...
}const servicesDir = path.join(root, 'services');
if (!fs.existsSync(servicesDir)) {
console.error('No services directory found.');
process.exit(1);
}
const services = fs.readdirSync(servicesDir);
if (services.length === 0) {
console.log('No Node-based services with package.json to run.');
process.exit(0);
}it('starts node service and performs health check', async () => {
const repoRoot = process.cwd();
const cliPath = path.join(repoRoot, 'bin/index.js');
await execa('node', [cliPath, 'init', projName, '--services', 'node', '--no-install', '--yes'], { cwd: tmpDir, env: { ...process.env, CI: 'true' } });
// ...
});These code locations are relevant for debugging and fixing issues with service startup via the run command.
