    Serverless Webpack

    Serverless Webpack

    Serverless plugin to bundle your lambdas with Webpack

    A Serverless Framework plugin to build your lambda functions with Webpack. When enabled in your service configuration, functions are packaged and compiled individually, resulting in smaller Lambda packages that contain only the code and dependencies needed to run the function. This allows the plugin to fully utilize WebPack's Tree-Shaking optimization. Configuration possibilities range from zero-config to fully customizable. Support of serverless package, serverless deploy and serverless deploy function. Support of serverless invoke local and serverless invoke local --watch. Support of serverless run and serverless run --watch. Integrates with serverless-offline to simulate local API Gateway endpoints. Cleaned up configuration. You should now use a custom.webpack object to configure everything relevant for the plugin. The old configuration still works but will be removed in the next major release.

    Shimport

    Shimport

    Use JavaScript modules in all browsers, including dynamic imports

    Shimport is a tiny JavaScript shim for using module import and export syntax in browsers that do not fully support native modules. It allows developers to work with JavaScript modules, including dynamic import behavior, across a wider range of browser environments. The project is intentionally small, making it useful when developers need compatibility without adding a large bundling or transpilation layer. Shimport helps bridge modern module syntax with older runtime support expectations. It can be useful for demos, lightweight applications, educational examples, and compatibility experiments. Its main value is making native-style JavaScript modules more broadly usable with minimal overhead.

    SingleFileZ

    SingleFileZ

    Web Extension for Firefox/MS Edge and CLI tool

    SingleFileZ is a fork of SingleFile that allows you to save a webpage as a self-extracting HTML file. This HTML file is also a valid ZIP file that contains the resources (images, fonts, stylesheets, and frames) of the saved page. This ZIP file can be unzipped on the filesystem in order, for example, to view the page in a browser that would not support pages saved with SingleFileZ. To open saved pages from the filesystem in a Chromium-based browser, SingleFileZ must be installed and the option "Allow access to file URLs" must be enabled in the details page of the extension. Otherwise, the browser must be started with the switch. To open saved pages from the filesystem in Safari, the option "Disable Local File Restrictions" must be selected in the "Develop" menu. SingleFileZ is available on Firefox, Chrome and Microsoft Edge. You can save web pages to HTML from the command line interface.

    SlimerJS

    SlimerJS

    A scriptable browser like PhantomJS, based on Firefox

    SlimerJS is a scriptable browser. It allows you to manipulate a web page with an external Javascript script: opening a webpage, clicking on links, modifying the content... It is useful to do functional tests, page automation, network monitoring, screen capture etc. It is a tool like PhantomJs, except that it runs Gecko instead of Webkit, and it is headless when using Firefox 56+. It can be used with Firefox 59. Higher version of Firefox is not supported and probably will not be supported in the future, as the development is suspended for now. SlimerJS provides the same API of PhantomJS. The current version of SlimerJS is highly compatible with PhantomJS 2.1. See current release notes in docs/release-notes-*.rst, and read the compatibility table to know the implementation level. The main goal of SlimerJS is to allow to execute all scripts developed for PhantomJS. So you could use tools like CasperJS. In fact, CasperJs 1.1 and higher can be executed with SlimerJS!

    SystemJS

    SystemJS

    Dynamic ES module loader

    SystemJS is a hookable, standards-based module loader. It provides a workflow where code written for production workflows of native ES modules in browsers (like Rollup code-splitting builds), can be transpiled to the System.register module format to work in older browsers that don't support native modules, running almost-native module speeds while supporting top-level await, dynamic import, circular references and live bindings, import.meta.url, module types, import maps, integrity and Content Security Policy with compatibility in older browsers back to IE11. SystemJS allows to write and use modular javacsript code that relies on ECMAScript 6 import and export statements. One good example is moment.js library, which started publishing ECMAScript 6 source code on npm since 2.10.0 release of moment.js. SystemJS requries a transpiler to compile ECMAScript 6 javacsript into a code that could be run in current versions of browsers and node.js.
