Grunt is a popular task runner on NodeJS. It is flexible and widely adopted. It is preferred tool when it comes to task automation. It offers lots of bundled plugins for common tasks.


  • It makes the workflow as easy as writing a setup file
  • It allows automating repetitive tasks with minimum effort
  • It has a straightforward approach. It includes tasks in JS and config in JSON
  • Grunt includes built-in tasks for extending the functionality of plugins and scripts
  • It speeds up the development process and increase the performance of projects
  • The ecosystem of Grunt is huge; so it is possible to automate anything with very less effort
  • This web development tool reduces the chance of getting errors while performing repetitive tasks


 Using Grunt, you can perform minification, compilation, and testing of files easily. You can easily work with a new codebase usingGrunt because it contains less infrastructure. It speeds up the development workflow and enhances the performance of projects.

What is grunt used for?

Grunt (software) Grunt is a JavaScript task runner, a tool used to automatically perform frequent tasks such as minification, compilation, unit testing, and linting. It uses a command-line interface to run custom tasks defined in a file (known as a Gruntfile). Grunt was created by Ben Alman and is written in Node.js.

Benefits of Grunt

Many people are of the opinion that the benefit of using Grunt (or any build tool for that matter) is to possibly save time, and often this tradeoff—of learning time versus actual development time is deemed too risky, which then leads to the programmer staying safe with the manual method. This perception is misguided. The added efficiency is only one of benefits of using Grunt, the other main benefits include: build consistency, increased effectiveness, community utilization, and task flexibility.


Hypothetically, let's say it takes us 2 minutes per build and we need to build (and run the tests) numerous times every hour, resulting in approximately 50 builds per day. With this schedule, it costs us approximately 100 minutes.

Building a foundation

If you have aspirations to lead a team, be responsible for other employees or grow into a C suite position, then it pays to develop the ability to relate to people in order to effectively manage them. One of the best ways to relate to people is to have empathy. And that comes from knowing the context of the hurdles they face and having first hand knowledge of what they are working on. This provides insight into their pain points and the techniques needed to solve them.

In fact, some of the most innovative leaders and best technical managers are the ones that still carve time out of their day to tinker. And while is it true that they may not have the time to engage in in a full coding set or build something complex from scratch, they still understand the language enough to know what they are looking for when they critique others’ work.

Proving worth

Grunt work also builds character. Because we grew up on technology where answers are often at our fingertips, we tend to think things should come to us much faster. In fact, if we cannot find a short cut it can feel as though valuable time is wasting away. But establishing credibility and building a reputation and rapport with colleagues takes time and considerable effort. And it is ok, even preferable in the long run, that most day to day work is not easy or perfect. Spending a lot of effort to achieve something provides a deeper level of satisfaction and fulfillment than accomplishing an easy goal.
