east migration progress indicator helper

East (node.js database migration tool) which provides migration helper to log progress.

Installation

npm install east-migration-progress-indicator-helper

Usage

Add this plugin to the plugins section to .eastrc e.g.:

{
  "plugins": ["east-migration-progress-indicator-helper"]
}

After that createProgressIndicator can be used in migrations e.g.:

exports.migrate = function(client, done) {
	const indicator = client.createProgressIndicator({total: 150});

	indicator.tick(5);

	setTimeout(() => {
		indicator.tick(45);
	}, 100);
	setTimeout(() => {
		indicator.tick(50);
	}, 100);
	setTimeout(() => {
		indicator.tick(50);
	}, 500);

	setTimeout(done, 1000);
};

indicator will be displayed as progress bar when stdout is tty:

Target migrations:
	2_doSomething
Migrate "2_doSomething"
[==============================] 150 / 150
Migration done

in case of non-tty stdout (file, etc) it will periodically log progress:

Target migrations:
	2_doSomething
Migrate "2_doSomething"
Progress: 5 / 150
Progress: 50 / 150
Progress: 100 / 150
Progress: 150 / 150
Migration done
