How to test your code in Node.js?

 The assert module in Node.js provides easy way of writing test in a limited ways. It provides no feedback when running your tests unless one fails. It provides 11 methods to test our code to check it is working as we expect. Some of them are: assert.equal, assert.deepEqual, assert.throws.

assert.equal(2 + 2, 4, 'two plus two is four');

Other than this, we can use testing frameworks like, mocha, chai and karma.

Which node logger did you use in your project?

Following are the common logger modules: 1) logger SUMMARY A simple logging library that combines the simple APIs of Ruby's logger.rb and browser-js console.log() USAGE A logger has 5 different levels of logging in a specific order: 'fatal', 'error', 'warn', 'info', 'debug' Each of these log levels has its own method on the logging instance. You can set the maximum log level on a logger at runtime. By default, a logger writes to STDOUT, but given a writeable file path, it will log directly to a file. Instantiation: // node/common.js style var logger = require('./logger').createLogger(); // logs to STDOUT var logger = require('./logger').createLogger('development.log'); // logs to a file 2)  simple-node-logger A simple multi-level logger for console, file, and rolling file appenders. Features include: levels: trace, debug, info, warn, error and fatal levels (plus all and off) flexible ap...

What is promise, promise.all and promise.race? How do you chain promises?

A promise is an object that may produce a single value some time in the future : either a resolved value, or a reason that it’s not resolved (e.g., a network error occurred). A promise is an object which can be returned synchronously from an asynchronous function. It will be in one of 3 possible states: Fulfilled:   onFulfilled()  will be called (e.g.,  resolve()  was called) Rejected:   onRejected()  will be called (e.g.,  reject()  was called) Pending:  not yet fulfilled or rejected A promise is  settled  if it’s not pending (it has been resolved or rejected). Sometimes people use  resolved  and  settled  to mean the same thing:  not pending . Once settled, a promise can not be resettled. Calling  resolve()  or  reject()  again will have no effect. The immutability of a settled promise is an important feature. Promises following the spec must follow a specific set of rules: A promise or...
