SuperTest
Super-agent driven library for testing node.js HTTP servers
A super-agent driven library for testing node.js HTTP servers using a fluent API. The motivation with this module is to provide a high-level abstraction for testing HTTP, while still allowing you to drop down to the lower-level API provided by superagent. Install SuperTest as an npm module and save it to your package.json file as a development dependency. You may pass an http.Server, or a Function to request(), if the server is not already listening for connections then it is bound to an ephemeral port for you so there is no need to keep track of ports. One thing to note, is that superagent now sends any HTTP error (anything other than a 2XX response code) to the callback as the first argument if you do not add a status code expect (i.e. .expect(302)). Expectations are run in the order of definition. This characteristic can be used to modify the response body or headers before executing an assertion. -

Svelte
Cybernetically enhanced web apps
Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM. Svelte shifts as much work as possible out of the browser and into your build step. No more manual optimizations, just faster, more efficient apps. Write breathtakingly concise components using languages you already know, HTML, CSS, and JavaScript. Oh, and your application bundles will be tiny as well. Built-in scoped styling, state management, motion primitives, form bindings and more — don't waste time trawling npm for the bare essentials. It's all here. -

TableExport
The simple, easy-to-implement library to export HTML tables to xlsx
The simple, easy-to-implement library to export HTML tables to xlsx, xls, csv, and txt files. To use this library, include the FileSaver.js library, and TableExport library before the closing body tag of your HTML document. In order to provide Office Open XML SpreadsheetML Format ( .xlsx ) support, you must include the following third-party library in your project before both FileSaver.js and TableExport. To support legacy browsers ( Chrome < 20, Firefox 13, Opera 12.10, IE, 10, Safari 6 ) include the Blob.js polyfill before the FileSaver.js script. Additional properties can be passed-in to customize the look and feel of your tables, buttons, and exported data. Notice that by default, TableExport will create export buttons for three different filetypes xls, csv, txt. You can choose which buttons to generate by setting the formats property to the filetype(s) of your choice. -

Vulcan
A toolkit to quickly build apps with React, GraphQL & Meteor
Vulcan is a framework that gives you a set of tools for quickly building React & GraphQL-based web applications. It can handle data loading, e-mail notifications, automatic form generation, and much more, out of the box. Vulcan is unique in that it spans the full-stack, from the database to the browser. While there exist many excellent back-end frameworks or backend-as-a-service providers, these all still require you to handle the front-end code yourself, including building a set of components to read, write, and display data. However, being full-stack, Vulcan is able to speed up these repetitive tasks by providing a whole range of helper components that are fine-tuned to the Vulcan back-end, and as a result just work out of the box. In order to make working with Vulcan easier (especially when it comes to updating the core packages), you are also free to follow the more complicated “two-repo” pattern, with the two repositories. -

Wasp
A programming language that understands what a web app is
Wasp (Web Application Specification Language) is a declarative DSL (domain-specific language) for developing, building and deploying modern full-stack web apps with less code. Concepts such as app, page, user, login, frontend, production, etc. are baked into the language, bringing a new level of expressiveness and allowing you to get more work done with fewer lines of code. While describing high-level features with Wasp, you still write the rest of your logic in your favorite technologies (currently React, NodeJS, Prisma). Wasp is in alpha and is therefore likely to change a lot, have bugs and miss important features. Due to its expressiveness, you can create and deploy a production-ready web app from scratch with very few lines of concise, consistent, declarative code. When you need more control than Wasp offers, you can write code in existing technologies such as js/html/css/... and combine it with Wasp code! -

eslint-plugin-jsdoc
JSDoc specific linting rules for ESLint
JSDoc specific linting rules for ESLint. Install ESLint either locally or globally. Rules may, as per the ESLint user guide, have their own individual options. In eslint-plugin-jsdoc, a few options, such as, exemptedBy and contexts, may be used across different rules. eslint-plugin-jsdoc options, if present, are generally in the form of an object supplied as the second argument in an array after the error level (any exceptions to this format are explained within that rule's docs). One can use minLines and maxLines to indicate how many line breaks (if any) will be checked to find a jsdoc comment block before the given code block. These settings default to 0 and 1 respectively. In conjunction with the require-jsdoc rule, these settings can be enforced so as to report problems if a jsdoc block is not found within the specified boundaries. The settings are also used in the fixer to determine how many line breaks to add when a block is missing. -

jqGrid
jQuery grid plugin
jqGrid is an Ajax-enabled JavaScript control that provides solutions for representing and manipulating tabular data on the web. Since the grid is a client-side solution, loading data dynamically through Ajax callbacks, it can be integrated with any server-side technology, including PHP, ASP, Java Servlets, JSP, ColdFusion, and Perl. Improve the maxGridHeigh method. Add a third parameter to indicate the minimum height at which the method run. jqGrid uses a jQuery JavaScript Library and is written as a plug-in for that package. JqGrid was developed by Tony Tomov at Trirand Inc., a software development firm based in Sofia. Trirand specializes in the development of web components and embraces free and open standards like jQuery, ThemeRoller, & jQuery UI. Tony got the idea for jqGrid when he needed an easy way to represent database information in a project. The first requirement was speed and the second, was independence from server-side technology and the database backend. -

stylus
Expressive, robust, feature-rich CSS language built for nodejs
Stylus is a revolutionary new language, providing an efficient, dynamic, and expressive way to generate CSS. Supporting both an indented syntax and regular CSS style. Installing Stylus is very easy once you have Node.js. So get the binaries for your platform and make sure that they also include npm, Node’s package manager. Stylus features powerful in-language function definitions. Function definitions appear identical to mixins; however, functions may return a value. Optional arguments may default to a given expression. With Stylus we may even default arguments to earlier arguments! Stylus is an innovative stylesheet language that compiles down to CSS. Inspired by SASS, Stylus is built with node.js and capable of running in the browser. Stylus is “pythonic” (i.e. indentation-based). Whitespace is significant, so we substitute { and } with an indent, and an outdent. Stylus, just like CSS, allows you to define properties for several selectors at once through comma separation. -

ungit
A tool to simplify the use of git, on any platform, anywhere
Git is known for being a versatile distributed source control system that is a staple of many individuals, communities, and even for the City of Chattanooga to crowd source bicycle parking locations. However, it is not known for userfriendliness or easy learning curve. Ungit brings user friendliness to git without sacrificing the versatility of git. Git and github both supports PGP signing. Within Ungit these features can be enabled. Currently, Ungit DOES NOT support GPG authentication! While git allows robust programmatic authentication via credential-helper, I could not find an easy way to do something equivalent with GPG. Therefore, password-less gpg authentication or 3rd party gpg password must be configured when using Ungit to commit with gpg. Ungit will watch git directory recursively upon page view and automatically refresh contents on git operations or changes on files that are not configured to be ignored in .gitignore. -
