Migration -t Flag Documentation Missing

[arnmishra]

Documentation Issue

What was unclear or otherwise insufficient?

It seems like the -t flag for typeorm migrations is missing in the documentation. We found a reference to it here #1408 and were able to figure out other options (like each) by looking at the code here

typeorm/src/commands/MigrationRunCommand.ts

Lines 61 to 73 in 4f7481b

	switch (args.t) {
	case "all":
	options.transaction = "all";
	break;
	case "none":
	case "false":
	options.transaction = "none";
	break;
	case "each":
	options.transaction = "each";
	break;
	default:
	// noop

and here https://github.com/typeorm/typeorm/blob/master/src/migration/MigrationExecutor.ts#L23-L26. I was looking at the documentation here https://typeorm.io/#/migrations/running-and-reverting-migrations

Recommended Fix

I think we should add documentation around the different -t options and what they result in.
