[AskJS] What is the one npm package that changed your life?

• redux

  13 55,566 8.8 TypeScript

  Discontinued Predictable state container for JavaScript apps [Moved to: https://github.com/reduxjs/redux] (by reactjs)

  

I got involved with Redux rather "accidentally" about 6 months after it came out, by volunteering to write an FAQ page for the docs.

• ESLint

  380 24,281 9.7 JavaScript

  Find and fix problems in your JavaScript code.

  

I'd have to say utilities like eslint and stylelint. Being able to open a repo from anyone in my company and know that it's going to be formatted in exactly the same style is incredible. I don't have to juggle different stylistic choices, tabs vs spaces, or any of that nonsense. And it integrates seamlessly into VSCode. Or even when opening repos from other users or companies - if they have a good linting workflow setup, I don't have to worry about breaking their style guidelines as I can just run their autofix scripts before submitting a PR.

• SurveyJS

  surveyjs.io sponsored

  Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc.

• lodash

  187 58,868 5.1 JavaScript

  A modern JavaScript utility library delivering modularity, performance, & extras.

  

In recent past? lodash for sure. Having so many utilities in a single package was fantastic. Nowadays many of these have native (faster) alternatives, but it's still a great little package.

• jQuery

  166 58,890 8.5 JavaScript

  jQuery JavaScript Library

  

In the distance past? Definitely jquery. Whilst there's no reason to start a new project with it today, jQuery set the standard for cross-browser DOM manipulation long before we had consensus on querySelector and things, and it'll always have a place in my heart.

• liqvid

  40 738 5.6 TypeScript

  Library for interactive videos in React

  

ractive-player since I've spent hundreds of hours of my life on it :)

• fs-extra

  16 9,347 5.6 JavaScript

  Node.js: extra methods for the fs object like copy(), remove(), mkdirs()

• moment

  97 47,790 7.2 JavaScript

  Parse, validate, manipulate, and display dates in javascript.

  

Moment - I loathe having to fight dates and times with vanilla JS.

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• Flarum

  59 14,904 2.8 PHP

  Simple forum software for building great communities.

  

Mithril is pretty great, they're big lovers of it over at https://flarum.org/. I love being able to use it with JSX without all the complexities of React.

• async

  16 28,071 8.1 JavaScript

  Async utilities for node and the browser
