    Jimp

    Jimp

    An image processing library written entirely in JavaScript for Node

    An image processing library for Node written entirely in JavaScript, with zero native dependencies. If you're using this library with TypeScript the method of importing slightly differs from JavaScript. Instead of using require, you must import it with ES6 default import scheme. If you're using a web bundles (webpack, rollup, parcel) you can benefit from using the module build of jimp. Using the module build will allow your bundler to understand your code better and exclude things you aren't using. If you're using webpack you can set process.browser to true and your build of jimp will exclude certain parts, making it load faster. The static Jimp.read method takes the path to a file, URL, dimensions, a Jimp instance or a buffer and returns a Promise. In some cases, you need to pass additional parameters with an image's URL.

    SuperAgent

    SuperAgent

    Ajax for Node.js and browsers (JS HTTP client)

    SuperAgent is light-weight progressive ajax API crafted for flexibility, readability, and a low learning curve after being frustrated with many of the existing request APIs. It also works with Node.js! Small progressive client-side HTTP request library, and Node.js module with the same API, supporting many high-level HTTP client features. Browser-ready versions of this module are available via jsdelivr, unpkg, and also in the node_modules/superagent/dist folder in downloads of the superagent package. If you are using browserify, webpack, rollup, or another bundler, then you can follow the same usage as Node. SuperAgent is easily extended via plugins. The Node client supports making requests to Unix Domain Sockets. DELETE, HEAD, PATCH, POST, and PUT requests can also be used, simply change the method name. Absolute URLs can be used. In web browsers absolute URLs work only if the server implements CORS.

    Angular Websocket

    Angular Websocket

    The missing Angular WebSocket module for connecting client apps

    Angular Websocket is a WebSocket service tailored for AngularJS 1.x applications, exposed primarily through the $websocket factory in the ngWebSocket module. It wraps the native WebSocket API in a way that plays nicely with Angular’s digest cycle, ensuring that UI updates are triggered when messages arrive. The library manages an internal send queue so that messages requested before the socket is open are safely sent once the connection is ready. It offers a set of convenience methods and callbacks, such as onMessage, onOpen, onClose, and onError, to keep WebSocket handling consistent with other Angular services. Developers can filter messages by string or regular expression and optionally disable automatic $digest calls when needed for performance. The project can be consumed via Bower, npm, CDN, or manual download, making it easy to introduce into legacy build setups. It aims to be the “missing WebSocket module” for AngularJS.

    undici

    An HTTP/1.1 client, written from scratch for Node.js

    An HTTP/1.1 client, written from scratch for Node.js. This section documents our most commonly used API methods. Additional APIs are documented in their own files within the docs folder and are accessible via the navigation list on the left side of the docs site. Garbage collection in Node is less aggressive and deterministic (due to the lack of clear idle periods that browsers have through the rendering refresh rate) which means that leaving the release of connection resources to the garbage collector can lead to excessive connection usage, reduced performance (due to less connection re-use), and even stalls or deadlocks when running out of connections.

    Apisauce

    Apisauce

    Axios + standardized errors + request/response transforms

    Talking to APIs doesn't have to be awkward anymore. Low-fat wrapper for the amazing Axios HTTP client library. All responses follow the same flow: success and failure alike. Responses have a problem property to help guide exception flow, attach functions that get called each request, attach functions that change all request or response data. Detects connection issues (on React Native). The only required property is baseURL and it should be the starting point for your API. It can contain a sub-path and a port as well. The responses are promise-based, so you'll need to handle things in a .then() function. The promise is always resolved with a response object. Even if there was a problem with the request! This is one of the goals of this library. It ensures sane calling code without having to handle .catch and has 2 separate flows.

    Just-API

    Just-API

    Test REST, GraphQL APIs

    Just-API is a declarative, specification-based test framework for REST, GraphQL APIs. Users can test APIs without writing code, but they can also tap into code when they want to. It reads API test specifications from YAML files and runs them in serial/parallel mode. Test reports can be generated in several formats including HTML and JSON. In simple terms, users build a test suite by providing a set of request and response validation specification in a YAML file. Each suite can have one or more specs. Just-API builds the request, sends it to the server and validates the response as per the specification. Runs test suites in parallel/serial mode. Supports all widely used HTTP methods. Supports x-www-form-urlencoded requests, Multipart requests, File uploads. Built-in Response Validation Constructs(Headers, Cookies, Status code, JSON body, JSON schema) Custom Response validator functions. Supports running custom inline or module javascript sync/async functions.

    find-my-way

    find-my-way

    A crazy fast HTTP router

    A crazy fast HTTP router, internally uses a highly performant Radix Tree (aka compact Prefix Tree), supports route params, wildcards, and it's framework is independent. You can set a custom length for parameters in parametric (standard, regex and multi) routes by using maxParamLength option, the default value is 100 characters. If you are using a regex-based route, find-my-way will throw an error if detects potentially catastrophic exponential-time regular expressions (internally uses safe-regex2). According to RFC3986, find-my-way is case-sensitive by default. You can disable this by setting the caseSensitive option to false: in that case, all paths will be matched as lowercase, but the route parameters or wildcards will maintain their original letter casing.

    r2

    r2

    HTTP client, spiritual successor to request

    Early in Node.js I wrote an HTTP client library called request. It evolved along with Node.js and eventually became very widely depended upon. A lot has changed since 2010 and I've decided to re-think what a simple HTTP client library should look like. This new library, r2, is a completely new approach from request. Rather than being built on top of the Node.js Core HTTP library and shimmed for the browser, r2 is built on top of the browser's Fetch API and shimmed for Node.js. APIs are meant to be used with async/await, which means they are based on promises. Being written to the Fetch API is a huge benefit for browser users. When running through browserify request is ~2M uncompressed and ~500K compressed. r2 is only 66K uncompressed and 16K compressed.

    vue-resource

    vue-resource

    The HTTP client for Vue.js

    vue-resource is a plugin for Vue.js which provides services for making web requests and handle responses using a XMLHttpRequest or JSONP. You can install it via yarn or NPM. Available on jsdelivr, unpkg or cdnjs. Typescript for vue-resource should work out of the box since the type definition files are included within the npm package. The http service can be used globally Vue.http or in a Vue instance this.$http. A Vue instance provides the this.$http service which can send HTTP requests. A request method call returns a Promise that resolves to the response. Also the Vue instance will be automatically bound to this in all function callbacks. Shortcut methods are available for all request types. These methods work globally or in a Vue instance. The Recipes provide code examples to common use-cases. If you want to share your recipe feel free to send a pull request.
