Iosevka
Versatile typeface for code, from code
Iosevka is an open-source, sans-serif + slab-serif, monospace + quasi‑proportional typeface family, designed for writing code, using in terminals, and preparing technical documents. The Iosevka’s monospace family is provided in a slender outfit by default: glyphs are exactly 1/2em wide. Compared to the competitors, you could fit more columns within the same screen width. Iosevka provides two widths, Normal and Extended. If you prefer more breeze between the character, choose Extended and enjoy. Terminal emulators have a stricter compatibility requirements for fonts. Therefore, Iosevka and Iosevka Slab all contain two specialized families, Term and Fixed, targeting terminal users. In these families, the symbols will be narrower to follow terminals’ ideology of column count. In the Fixed families, the ligation will be disabled to ensure better compatibility in certain environments. -

eslint-plugin-jsx-a11y
Static AST checker for a11y rules on JSX elements
Static AST checker for accessibility rules on JSX elements. This plugin does a static evaluation of the JSX to spot accessibility issues in React apps. Because it only catches errors in static code, use it in combination with axe-core/react to test the accessibility of the rendered DOM. Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology. If you installed ESLint globally (using the -g flag in npm, or the global prefix in yarn) then you must also install eslint-plugin-jsx-a11y globally. To enable your custom components to be checked as DOM elements, you can set global settings in your configuration file by mapping each custom component name to a DOM element type. Enforce all elements that require alternative text have meaningful information to relay back to the end user. -

prettier-eslint
Formats your JavaScript using prettier followed by eslint --fix
The fix feature of eslint is pretty great and can auto-format/fix much of your code according to your ESLint config. prettier is a more powerful automatic formatter. One of the nice things about prettier is how opinionated it is. Unfortunately, it's not opinionated enough and/or some opinions differ from my own. So after prettier formats the code, I start getting linting errors. This formats your code via prettier, and then passes the result of that to eslint --fix. This way you can get the benefits of prettier's superior formatting capabilities, but also benefit from the configuration capabilities of eslint. The path of the file being formatted can be used to override eslintConfig (eslint will be used to find the relevant config for the file). -

Commander.js
node.js command-line interfaces made easy
The complete solution for node.js command-line interfaces. Commander exports a global object which is convenient for quick programs. For larger programs which may use commander in multiple ways, including unit testing, it is better to create a local Command object to use. Each option can have a short flag (single character) and a long name, separated by a comma or space or vertical bar ('|'). Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, followed by a single option taking a value (possibly followed by the value). You may specify a function to do custom processing of option-arguments. The callback function receives two parameters, the user specified option-argument and the previous value for the option. It returns the new value for the option. This allows you to coerce the option-argument to the desired type, or accumulate values, or do entirely custom processing. -

Lebab
Turn your ES5 code into readable ES6
Turn your ES5 code into readable ES6. Lebab does the opposite of what Babel does. Lebab transpiles your ES5 code to ES6/ES7. It does exactly the opposite of what Babel does. Convert your old-fashioned code using the lebab cli tool, enabling a specific transformation. The recommended way of using Lebab is to apply one transform at a time, read what exactly the transform does and what are its limitations, apply it to your code and inspect the diff carefully. Transforms can be applied with relatively high confidence. They use pretty straightforward and strict rules for changing the code. The resulting code should be almost 100% equivalent to the original code. Transforms should be applied with caution. They either use heuristics that can't guarantee that the resulting code is equivalent of the original code, or they have significant bugs which can result in breaking your code. -

eslint-config-alloy
Progressive ESLint config for your React/Vue/TypeScript projects
Progressive ESLint config for your React/Vue/TypeScript projects. The AlloyTeam ESLint config is not only a progressive ESLint config for your React/Vue/TypeScript projects but also the best reference for configuring your personalized ESLint rules. Let Prettier handle style-related rules. Inherit ESLint's philosophy and help everyone build their own rules. High degree of automation: advanced rules management, test as a document, as a website. Keep up with the times, follow up the latest rules as soon as possible. It is recommended to use npm init vue@3 to create a project with Vue, TypeScript and ESLint integrated. Our team initially used Airbnb rules, but because it was too strict, some rules still needed to be personalized, which led to more and more changes in the future and finally decided to maintain a new set. After more than four years of maintaining, eslint-config-alloy is now very mature and progressive and has been welcomed by many teams inside and outside the company. -

jscodeshift
A JavaScript codemod toolkit
jscodeshift is a toolkit for running codemods over multiple JavaScript or TypeScript files. It provides A runner, which executes the provided transform for each file passed to it. It also outputs a summary of how many files have (not) been transformed. A wrapper around recast, providing a different API. Recast is an AST-to-AST transform tool and also tries to preserve the style of original code as much as possible. As already mentioned, jscodeshift also provides a wrapper around recast. In order to properly use the jscodeshift API, one has to understand the basic building blocks of recast (and ASTs) as well. An AST node is a plain JavaScript object with a specific set of fields, in accordance with the Mozilla Parser API. The primary way to identify nodes is via their type. It's OK to not know the structure of every AST node type. The (esprima) AST explorer is an online tool to inspect the AST for a given piece of JS code. -

eslint-plugin-flowtype
Flow type linting rules for ESLint
Flow type linting rules for ESLint. This plugin exports a recommended configuration that enforces Flow type good practices. To enable this configuration use the extends property in your .eslintrc config file. ESLint is designed to be flexible and configurable for your use case. You can turn off every rule and run only with basic syntax validation or mix and match the bundled rules and your custom rules to fit the needs of your project. There are two primary ways to configure ESLint. Use JavaScript comments to embed configuration information directly into a file. Use a JavaScript, JSON, or YAML file to specify configuration information for an entire directory and all of its subdirectories. This can be in the form of a .eslintrc.* file or an eslintConfig field in a package.json file, both of which ESLint will look for and read automatically, or you can specify a configuration file on the command line. -

eslint-plugin-import
ESLint plugin with rules that help validate proper imports.
This plugin intends to support linting of ES2015+ (ES6+) import/export syntax, and prevent issues with misspelling of file paths and import names. All the goodness that the ES2015+ static module syntax intends to provide, is marked up in your editor. The maintainers of eslint-plugin-import and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open-source dependencies you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use. With the advent of module bundlers and the current state of modules and module syntax specs, it's not always obvious where import x from 'module' should look to find the file behind module. Up through v0.10ish, this plugin has directly used substack's resolve plugin, which implements Node's import behavior. This works pretty well in most cases. -

rest.js
GitHub REST API client for JavaScript
GitHub REST API client for JavaScript. Import the Octokit constructor based on your platform. Instantiate your octokit API. All options are optional, but authentication is strongly encouraged. API Previews can be enabled globally by setting the previews option. They can be set per-request as well. A default time zone can be enabled by setting the timeZone option. In order to use Octokit with GitHub Enterprise, set the baseUrl option. Most of GitHub’s REST API endpoints have matching methods. All endpoint methods are asynchronous, in order to use await in the code examples, we wrap them into an anonymous async function. Authentication is optional for some REST API endpoints accessing public data, but is required for GraphQL queries. Using authentication also increases your API rate limit. -

CSSLint
Automated linting of cascading stylesheets
CSSLint is an open-source CSS code quality tool originally written by Nicholas C. Zakas and Nicole Sullivan. A lint tool performs static analysis of source code and flags patterns that might be errors or otherwise cause problems for the developer. CSSLint is a tool to help point out problems with your CSS code. It does basic syntax checking as well as applying a set of rules to the code that look for problematic patterns or signs of inefficiency. The rules are all pluggable, so you can easily write your own or omit ones you don't want. You can integrate CSSLint into your favorite IDE to make checking your CSS code quality easy. In fact, some IDEs already have CSSLint built-in. Once you're familiar with the CSSLint command-line interface, the next step is to integrate it into your build system. -

Prepack
A JavaScript bundle optimizer
A tool for making JavaScript code run faster. Prepack is still in an early development stage and not ready for production use just yet. Please try it out, give feedback, and help fix bugs. Prepack is a tool that optimizes JavaScript source code: Computations that can be done at compile-time instead of run-time get eliminated. Prepack replaces the global code of a JavaScript bundle with equivalent code that is a simple sequence of assignments. This gets rid of most intermediate computations and object allocations. Prepack operates at the AST level, using Babel to parse and generate JavaScript source code. At the core of Prepack is an almost ECMAScript 5 compatible interpreter — implemented in JavaScript! The interpreter closely follows the ECMAScript 2016 Language Specification, with a focus on correctness and spec conformance. You can think of the interpreter in Prepack as a clean reference implementation of JavaScript. -

eslint-config
Anthony's ESLint config presets
Anthony's ESLint config presets. Auto fix for formatting (aimed to be used standalone without Prettier). Designed to work with TypeScript, Vue out-of-box. Lint also for json, yaml, markdown. Sorted imports, dangling commas for cleaner commit diff. Reasonable defaults, best practices, only one-line of config. -
19
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. -

esprint
Fast eslint runner
esprint (pronounced E-S-sprint) speeds up eslint by running the linting engine across multiple threads. esprint sets up a server daemon to cache the lint status of each file in memory. It uses a watcher to determine when files change, to only lint files as necessary. It also has a CI mode where it does not set up a daemon and just lints in parallel. In order to use esprint, first place an .esprintrc file in the root directory your project. This is similar to a .flowconfig if you use flow types. The .esprintrc file describes which paths to lint and which paths to ignore. You can also override the port to start the background server on. esprint will find the root of your project automatically and lint the whole project. In default mode, esprint will start a background server to watch source files and cache lint results in memory. -

mevn
Light speed setup for MEVN(Mongo Express Vue Node) Apps
MEVN-CLI takes care of everything from project scaffolding to the deployment phase. Deploy your production-ready application to the cloud solution of choice. Get up and running with a multi-container Docker application in no time. A CLI tool for getting started with the MEVN stack. It offers a super-simple boilerplate template and additional utilities for building a MEVN stack-based webapp. It takes away the hassle of setting up the local development environment which may become a nightmare especially for beginners who are just starting out. As per the traditional approach, Developers are required to make their hands dirty setting up the local development environment which can be a pain, especially for beginners (as mentioned above). Also, it consumes time which can be utilized in building the actual product. We can also see this in the deployment phase where they may face trouble. All these can serve as demotivating factors for novices. It is here where MEVN-CLI comes into play. -

Restangular
AngularJS service to handle Rest API Restful Resources
Restangular is an AngularJS service that simplifies common GET, POST, DELETE, and UPDATE requests with a minimum of client code. It's a perfect fit for any WebApp that consumes data from a RESTful API. Note This version of Restangular only supports Angular 1. For an Angular 2+ version of Restangular, check out ngx-restangular. It's a separate project with different maintainers, so issues regarding ngx-restangular should be reported over there. Learn Restangular! Try the live demo on plunkr. It uses the same example as the official Angular Javascript Project, but with Restangular! With $resource, you need to write the URL Template. In here, you don't write any urls. You just write the name of the resource you want to fetch and that's it. You don't have to know the URL, the path, or anything to do all of the HTTP operations you want. You can create your own methods to run the operation that you want. The sky is the limit. -
