    phantomas

    phantomas

    Headless Chromium-based web performance metrics collector

    Headless Chromium-based modular web performance metrics collector. Modular approach, each metric is generated by a separate "module". phantomas "core" acts as an events emitter that each module can hook into. In-depth metrics such as: number of events bound via jQuery, calls to window.writeor complex and duplicated CSS selectors (via analyze-css). JSON as an output format. Easy integration with other nodejs projects via CommonJS module (see API docs). Metrics can be emitted from the JavaScript code of the page phantomas is run against (thanks to helper functions available in window.__phantomas). Device profiles allow phantomas to emulate mobile or tablet (by setting a proper user agent and viewport). phantomas comes as a CommonJS module that you can use in your nodejs projects. Use grunt to automate daily dev tasks, including your's application web performance.

    jQuery Form

    jQuery Form

    jQuery form plugin

    The jQuery Form Plugin allows you to easily and unobtrusively upgrade HTML forms to use AJAX. The jQuery Form Plugin allows you to easily and unobtrusively upgrade HTML forms to use AJAX. The main methods, ajaxForm and ajaxSubmit, gather information from the form element to determine how to manage the submit process. Both of these methods support numerous options which allows you to have full control over how the data is submitted. Submitting a form with AJAX doesn’t get any easier than this! When this form has been submitted the name and comment fields will be posted to comment.php. If the server returns a success status then the user will see a “Thank you” message. Add a form to your page. Just a normal form, no special markup required. Include jQuery and the Form Plugin external script files and a short script to initialize the form when the DOM is ready.

    Wretch

    Wretch

    A tiny wrapper built around fetch with an intuitive syntax

    A tiny (~ 3Kb g-zipped) wrapper built around fetch with an intuitive syntax. Wretch is compatible with modern browsers out of the box. For older environments without fetch support, you should get a polyfill. Converts a javascript object to query parameters, then appends this query string to the current url. String values are used as the query string verbatim. Only compatible with browsers that support AbortControllers. Otherwise, you could use a (partial) polyfill. Associates a custom controller with the request. Useful when you need to use your own AbortController, otherwise wretch will create a new controller itself. Aborts the request after a fixed time. If you use a custom AbortController associated with the request, pass it as the second argument. Returns the automatically generated AbortController alongside the current wretch response as a pair.

    AST explorer

    AST explorer

    A web tool to explore the ASTs generated by various parsers

    Paste or drop code into the editor and inspect the generated AST. Depending on the parser settings, it not only supports ES5/CSS3. Since the future syntax is supported, the AST explorer is a useful tool for developers who want to create AST transforms. In fact, transformers are included so you can prototype your own plugins. Save and fork code snippets. Copy the URL to share them. Copying an AST or dropping a file containing an AST into the window will parse the AST and update the code using escodegen. Otherwise, the content of the text editor will be replaced with the content of the file (i.e. you can drag and drop JS files). Choose between multiple parsers and configure them. shift+click on a node expands the full subtree. Hovering over a node highlights the corresponding text in the source code. Editing the source or moving the cursor around will automatically highlight the corresponding AST node (or its ancestors of it isn't expanded).

    Bliss

    Bliss

    Blissful JavaScript

    Want to use Vanilla JS but find native APIs a bit unwieldy? Bliss is for you. Designed to work with Vanilla JS, not replace it. Only adds one _ property (optional, customizable). Know what you’re running. Excellent for learning. Use polyfills to extend browser support. Adding new blissful methods is easy as pie! Only 3KB minified & gzipped! Bliss is just a collection of helpers and light syntactic sugar over Vanilla JS. It does not account for browser bugs or lack of support of certain APIs, although it only uses features that are both supported across most modern browsers and can be polyfilled. For example, it uses Promises throughout (supported by all latest browsers, can be polyfilled), but, despite the temptation, not arrow functions (syntactic extension, cannot be polyfilled). The idea is that you can extend support by using polyfills, depending on your needs.

    Koa Router, based on OpenAPI, Swagger and Json Schema

    I have used Markdown and wiki to manage API doc, from which I have suffered a lot. It wastes too much time and is very boring. The document should be repaired when you change the API. It's very inconvenient to test and debug. The management of API doc totally depends on people. As a result, it is hard to make documents have high quality. Meanwhile, the developers will spend more time on testing, which may have a bad effect on the project.

    Pjax module

    Pjax module

    Easily enable fast Ajax navigation on any website

    Pjax is a standalone JavaScript module that uses AJAX (XmlHttpRequest) and pushState() to deliver a fast browsing experience. It allows you to completely transform the user experience of standard websites (server-side generated or static ones) to make users feel like they are browsing an app, especially for those with low bandwidth connections. Pjax does not rely on other libraries, like jQuery or similar. It is written entirely in vanilla JS. Pjax loads pages using AJAX and updates the browser's current URL using pushState() without reloading your page's layout or any resources (JS, CSS), giving a fast page load. It works with all permalinks and can update all the parts of the page you want (including HTML metas, title, and navigation state). It listens to every click on links you want (by default all of them). When an internal link is clicked, Pjax fetches the page's HTML via AJAX.

    Tabulator

    Tabulator

    Interactive tables and data grids for JavaScript

    Tabulator allows you to create interactive tables in seconds from any HTML Table, Javascript Array or JSON formatted data. Simply include the library and the css in your project and you're away! Tabulator has an enormous number of features to help customize your table experience to your needs. With new features released every month, there is bound to be something to get your interactive table juices flowing. Tabulator is built to work with all the major front-end JavaScript frameworks including React, Angular and Vue. Header filters and programmatic filters can be set independently allowing you to use a header filter to further restrict the rows shown in an already filtered data set. If an input element is used as the filter element, the table will be filtered in real-time as the user types in the input element. To prevent excessive redrawing of the table Tabulator will wait 300 milliseconds after the user has finished typing before triggering the filter.

    css-spinner

    css-spinner

    Small, elegant pure css spinner for ajax or loading animation

    Open source CSS loading animations dedicated for speed, simplicity & dev-friendly. Loading.io's CSS spinner uses CSS Animation, which is wildly supported by all modern browsers such as Google Chrome and Mozilla Firefox. However, the Microsoft Internet Explorer version earlier than 10 doesn't support CSS Animation. To support older IE, you have to use a GIF format image. Choose one from loading.io's online spinner gallery and you can customize a unique loader GIF with our icon editor easily. Some older browsers need prefixes like '-WebKit-' to use CSS Animation. To minimize file size, we omitted all vendor prefixes in loaders' CSS, but you can customize this by building CSS from the source. We also provide stylus and pug source files for better integrating these spinners into your project. Find corresponding stylus and pug files for your desired spinners under src/ folders.
