Bluebird Tools

Tools to improve the bluebird promises with control flow and logging.

Install

npm install --save bluebird-tools

How to use

const Promise = require('bluebird-tools');

Control Flow

promise.iif(condition, success, fail) -> promise

Calls success if pass the condition or calls fail

Promise.resolve(1)
   .iif(x => x === 1, x => console.log('success', x), x => console.log('fail', x));

promise.when(condition, success) -> promise

Calls success if pass the condition or calls fail

Promise.resolve(1)
   .when(x => x === 1, x => console.log('success', x));

promise.unless(condition, fail) -> promise

Calls success if pass the condition or calls fail

Promise.resolve(1)
   .unless(x => x === 2, x => console.log('fail', x));

promise.thenMonitor(name, method) -> promise

Calls method monitoring starting and ending

Promise.resolve()
   .thenMonitor('something', () => executeSomething());
   // logs:
   // - starting something
   // - finishing something - 654ms

Logging

Configure logging for all Promise with the logging function. Default levels to call the log:

• silly
• debug
• verbose
• info
• warning
• error

Promise.configureLog(logging)

const winston = require('winston');

// configure winston

Promise.configureLog(function logging(level, text, ...args) {
	winston.log(level, text, ...args);
});

Promise.log(level, text, ...args) -> promise

Promise.log('info', 'testing log', 1, 2, 3);

promise.log(level, text, ...args) -> promise

Promise.resolve().log('info', 'testing log', 1, 2, 3);

promise.silly(text, ...args) -> promise

Promise.resolve().silly('testing log', 1, 2, 3);

promise.debug(text, ...args) -> promise

Promise.resolve().debug('testing log', 1, 2, 3);

promise.verbose(text, ...args) -> promise

Promise.resolve().verbose('testing log', 1, 2, 3);

promise.info(text, ...args) -> promise

Promise.resolve().info('testing log', 1, 2, 3);

promise.warning(text, ...args) -> promise

Promise.resolve().warning('testing log', 1, 2, 3);

promise.error(text, ...args) -> promise

Promise.resolve().error('testing log', 1, 2, 3);

promise.whenLog(level, conditional, text, ...args) -> promise

Promise.resolve(1).whenLog('into', x => x === 1, 'testing log', 1, 2, 3);

promise.unlessLog(level, conditional, text, ...args) -> promise

Promise.resolve(1).unlessLog('into', x => x === 2, 'testing log', 1, 2, 3);

Manipulating promises

Promise.convert(promise) -> promise

Converts a native promise to a BluebirdTools promise

Promise.convert(promise)
