Electron Packager
Customize and package your Electron app with OS-specific bundles
Electron Packager is a command line tool and Node.js library that bundles Electron-based application source code with a renamed Electron executable and supporting files into folders ready for distribution. For creating distributables like installers and Linux packages, consider using either Electron Forge (which uses Electron Packager internally), or one of the related Electron tools, which utilizes Electron Packager-created folders as a basis. Note that packaged Electron applications can be relatively large. A zipped, minimal Electron application is approximately the same size as the zipped prebuilt binary for a given target platform, target arch, and Electron version (files named electron-v${version}-${platform}-${arch}.zip). Building an Electron app for the Windows target platform requires editing the Electron.exe file. Currently, Electron Packager uses node-rcedit to accomplish this. -

HTM
JSX alternative using standard tagged templates, with compiler support
htm is JSX-like syntax in plain JavaScript, no transpiler necessary. Develop with React/Preact directly in the browser, then compile htm away for production. It uses standard JavaScript Tagged Templates and works in all modern browsers. The syntax you write when using HTM is as close as possible to JSX. htm actually takes the JSX-style syntax a couple steps further! No transpiler necessary. HTML's optional quotes: <div class=foo>. Component end-tags: <${Footer}>footer content<//>. Syntax highlighting and language support via the lit-html VSCode extension and vim-jsx-pretty plugin. Multiple root element (fragments): <div /><div />. Support for HTML-style comments: <div><!-- comment --></div>. htm is published to npm, and accessible via the unpkg.com CDN. If you're using Preact or React, we've included off-the-shelf bindings to make your life easier. They also have the added benefit of sharing a template cache across all modules. -

Retire.js
Scanner detecting the use of JavaScript libraries
There is a plethora of JavaScript libraries for use on the web and in node.js apps out there. This greatly simplifies, but we need to stay updated on security fixes. "Using Components with Known Vulnerabilities" is now a part of the OWASP Top 10 and insecure libraries can pose a huge risk for your web app. The goal of Retire.js is to help you detect the use of versions with known vulnerabilities. Scan a web app or node app for use of vulnerable JavaScript libraries and/or node modules. grunt-retire scans your grunt-enabled app for use of vulnerable JavaScript libraries and/or node modules. Scans visited sites for references to insecure libraries and puts warnings in the developer console. An icon on the address bar displays will also indicate if vulnerable libraries were loaded. Retire.js has been adapted as a plugin for the penetration testing tools Burp and OWASP ZAP. -

Rollup
A module bundler for JavaScript
Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD. ES modules let you freely and seamlessly combine the most useful individual functions from your favorite libraries. This will eventually be possible natively everywhere, but Rollup lets you do it today. Rollup can be used either through a command line interface with an optional configuration file, or else through its JavaScript API. Rollup allows you to write your code using the new module system, and will then compile it back down to existing supported formats such as CommonJS modules, AMD modules, and IIFE-style scripts. This means that you get to write future-proof code. -

SQLite compiled to JavaScript
A javascript library to run SQLite on the web
sql.js is a javascript SQL database. It allows you to create a relational database and query it entirely in the browser. You can try it in this online demo. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a JavaScript typed array. sql.js uses emscripten to compile SQLite to webassembly (or to javascript code for compatibility with older browsers). It includes contributed math and string extension functions. sql.js can be used like any traditional JavaScript library. If you are building a native application in JavaScript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to JavaScript. A native binding will not only be faster because it will run native code, but it will also be able to work on database files directly instead of having to load the entire database. -

Viewer.js
JavaScript image viewer
You may set viewer options with new Viewer(image, options). If you want to change the global default options, You may use Viewer.setDefaults(options). Enable the modal backdrop, specify static for the backdrop that will not close the modal on click. Specify the visibility and the content of the title. Filter the images for viewing (should return true if the image is viewable, return false to ignore the image). Indicate if toggle the image size between its natural size and initial size when double click on the image or not. As there are some asynchronous processes when start the viewer, you should call a method only when it is available. If you have to use another viewer with the same namespace, call the Viewer.noConflict static method to revert to it. -
