[Can be defered] [Not blocking PP, lower priority than compatible modes docs]

While we are at this. It would nice if sdk:generate also takes optional [serviceId] [connectorId] like other commands.

The rule of thumb from go/fdc:multi-data-source: if there are >1 services / connectors / datasource, it defaults to run the same routine against all relevant resources.

  dataconnect:services:list                                      list all deployed services in your Firebase

Filed b/369400626 to update all commands per go/fdc:multi-data-source, as I believe right now an error is thrown in diff/migrate/grant if serviceId isn't specified and multiple services exist.


export const command = new Command("dataconnect:sdk:generate")
.description("generates typed SDKs for your Data Connect connectors")
.action(async (options: Options) => {
.option(
"--watch",
"watch for changes to your connector GQL files and regenerate your SDKs when updates occur",
)
.action(async (options: GenerateOptions) => {
const projectId = needProjectId(options);

const services = readFirebaseJson(options.config);
