The ELKrnStack – Comprises three open-source projects — Elasticsearch, Logstash, andrnKibana. It is a basic and strong answer for log examination and gives bits ofrnknowledge on application exhibitions. The stack is principally utilized forrngathering and breaking down logs from applications, empowering quickerrninvestigating, gaining security examination, and that's just the beginning.
Prometheusrnis an open-source observing and alarming arrangement created by SoundCloud. Itrngives multi-dimensional information assortment and information lining andrnrecording constant measurements in a period series data set.
Grafana isrnanother open-source investigation programming that permits developers torntime-series data sets into effectively reasonable charts and representations.rnThroughout the long term, Grafana and Prometheus have turned into a favoredrnobserving stack for DevOps groups. While Prometheus gives a capacity backend,rnGrafana goes about as an interface for investigation and representation.
Do theyrnhave an essential comprehension of the Front-end stack?
AlthoughrnNode.js engineer's job is to deal with the backend of the web application,rnrudimentary information on frontend advances grasps their range of abilities.rnOn the off chance that backend developers know how backend parts power the UIrnto give a reliable client experience, they can adjust the code in a like mannerrnand meet client assumptions. Besides, it further develops group cooperationrnsince they have a common comprehension of their jobs.
When talkingrnabout applicants, we can examine their insight into HTML, JavaScript, CSS,rnAJAX, frontend structures like Angular and Vue, and libraries like React andrnJQuery. Furthermore, we can get some information about the similarity ofrnfrontend advances that are a great fit for Node.js applications to check theirrnfrontend understanding.

Wouldrnthey be able to work with various Test Runners and Tools?
As Node.jsrnis well known among most developers around the world, fresher testingrninstruments and systems are created, remembering the Node.js applications. Inrnany case, picking the right testing device requires understanding thernreasonableness of instruments depending on the task type, intricacies,rnnecessities, and numerous different elements. An accomplished engineer outlinesrnevery one of the holes and likely dangers in the code and recommends a testingrnsystem that yields better outcomes in web organizations.

Testingrnapparatuses prescribed by developers to assist us with surveying a competitor'srnmastery in testing Node.js applications –
Mocha – An open-source JS testingrnstructure running on Node.js. It is straightforward, quick, and extensible andrnruns nonconcurrent tests on Node.js applications. Also, Mocha is profoundlyrnviable with Chai, a statement library for JS systems. Both Mocha and Chairnsupport the Behavior Driven Development (BDD)/Test Driven Development (TDD)rnapproach.
Jasmine – Another BDD system for JavaScriptrnthat doesn't rely upon some other JS structures or DOM control. It has a spotlessrngrammar that makes composing tests simpler for developers.
Joke – A JS testing system andrnattestation library for Node.js applications. One of the vital highlights inrnthis system is its usefulness to run recently bombed tests and arrange trialsrndependent on the time taken to test records.
Ava – A test-sprinter for Node.js withrnbasic language structure and the capacity to run quick and simultaneous tests.rnIt accompanies a succinct API, definite mistake yield, and takes out thernutilization of globals.
Do theyrnhave experience working with elective Package Managers?
Node.jsrnutilizes all-around tried and open-source bundles that dispense with the needrnto modify code and advance quicker improvement. Developers use bundle directorsrnto deal with these bundles. Check if the competitor we will enlist has insidernand out information on npm—default bundle administrator for Node.js. One methodrnfor checking how knowledgeable a designer is to get information about thernvarious options for npm bundles to improve results.
rnFor example, Yarn is the most popular elective bundle chief for Node.jsrnapplications. It introduces bundles quicker than npm and utilizes the neighborhoodrnstore memory as opposed to sitting tight for the downloading system to finish.rnMoreover, it introduces bundles parallelly and organizes network demands in arnline to advance the organization through and through.
rnAnother option is ppm. Developers hail it for settling the NPM doppelgangerrnissues, i.e., ppm introduces one duplicate of the multitude of required bundlesrnon the circle, and a hard connection to the hub modules catalog is accessiblernfor establishment. This element saves circle space by and large.
