    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.

    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.

    Dredd

    Dredd

    Language-agnostic HTTP API Testing Tool

    Dredd is a language-agnostic command-line tool for validating API description documents against the backend implementation of the API. Dredd reads your API description and step by step validates whether your API implementation replies with responses as they are described in the documentation. Dredd supports writing hooks — a glue code for each test setup and teardown.

    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.
