In `@packages/cli/src/actions/proxy.ts`:
- Line 29: Fix the typo in the console log by removing the extra colon in the
template string used in the console.log call (console.log(colors.gray(`Loading
ZModel schema from:: ${schemaFile}`))); change "from::" to "from:" so it reads
`Loading ZModel schema from: ${schemaFile}`.
- Around line 156-171: The signal handlers for 'SIGTERM' and 'SIGINT' call
client.$disconnect() but don't await it before calling process.exit(0), so
convert the server.close callback to a promise (e.g., new Promise(resolve =>
server.close(resolve)) or use util.promisify) inside the process.on handlers,
await that promise and then await client.$disconnect() (wrap awaits in
try/catch), and only call process.exit(0) after both awaits complete to ensure
graceful cleanup; update both handlers where process.on('SIGTERM', async () => {
... }) and process.on('SIGINT', async () => { ... }) reference server.close and
client.$disconnect.
- Around line 58-60: The code passes an undefined provider into createDialect
because dataSource or its provider field may be missing; update the logic around
dataSource, the fields.find(...) result, and getStringLiteral to validate that a
provider string was actually found before calling createDialect, and if not,
throw or return a clear error (e.g., "Missing or invalid datasource provider")
that references the dataSource and provider, rather than allowing
createDialect(provider, ...) to receive undefined and produce an ambiguous
message.
In `@packages/cli/src/index.ts`:
- Around line 193-202: The port CLI option is parsed as a string by Commander
but your Options type and downstream functions (run(), startServer()) expect a
number; update the proxy command setup (the .addOption for '-p, --port <port>'
in the program.command('proxy') block) to parse the value into a number (e.g.,
use Option.argParser(Number) or a parseInt wrapper) and keep the default as a
numeric 8008, and ensure proxyAction signature/usage reads the parsed numeric
port to pass to run()/startServer().
🧹 Nitpick comments (3)
packages/cli/src/index.ts (1)
239-242: Consider a more robust check for the proxy command.The check
program.args.includes('proxy')could match if "proxy" appears as a value to another option (e.g.,--output proxy). While unlikely, this mirrors the existing pattern forgenerate --watch. If this becomes problematic, consider tracking the executed command name explicitly.packages/cli/src/actions/proxy.ts (2)
84-85: Variable shadowing reduces readability.The inner
valueshadows the outervalueparameter. Consider renaming for clarity.Suggested fix
const env = (varName: string) => { - const value = process.env[varName]; - if (!value) { + const envValue = process.env[varName]; + if (!envValue) { throw new CliError(`Environment variable ${varName} is not set`); } - return value; + return envValue; };
150-153: Consider adding a default port.If
options.portis undefined, Express will listen on a random port. Consider providing a sensible default for better developer experience.Suggested fix
- const server = app.listen(options.port, () => { - console.log(`ZenStack proxy server is running on port: ${options.port}`); + const port = options.port ?? 3000; + const server = app.listen(port, () => { + console.log(`ZenStack proxy server is running on port: ${port}`);

Learning: Do not use ts-expect-error in production code within the zenstackhq/zenstack-v3 repo (e.g., packages/*). Use explicit type annotations, targeted type assertions, or refactor to resolve the type error. ts-expect-error may be acceptable only in test files for stubbing or temporary silencing. Ensure production code is type-safe and maintainable.

Pull request overview
This pull request adds a new proxy command to the ZenStack CLI that starts a proxy server for connecting to ZenStack databases. The proxy server exposes REST API endpoints for database operations and schema introspection, enabling tools like ZenStack Studio to interact with the database.
Changes:
- Added new
proxycommand with support for SQLite and PostgreSQL databases - Refactored
getOutputPathutility to be shared betweengenerateandproxycommands - Moved
@zenstackhq/orm,@zenstackhq/server, and database driver dependencies from devDependencies to dependencies

For PostgreSQL connections, the Pool is created but never explicitly closed during shutdown. While client.$disconnect() might handle this, it's better to explicitly close the pool to ensure proper cleanup of database resources. Consider storing the pool reference and calling pool.end() in the shutdown handlers.

The port option accepts any number value without validation. Consider adding validation to ensure the port is within the valid range (1-65535) and providing a helpful error message if an invalid port is specified.

The cors package is added as a dependency in package.json and the type definitions are included, but cors is never imported or used in the code. If CORS functionality is needed for the Express server, it should be imported and applied using app.use(cors()). If not needed, the dependency should be removed.
