    TheoremJS

    TheoremJS

    A Math library for computation in JavaScript

    TheoremJS is a mathematical framework that is packed up with tons of useful mathematical functions. It is composed of functions in most mathematical fields such as algebra, number theory, statistics, etc... It was designed to fit your need, whatever you are trying to do. With TheoremJS, you won't feel the need of running the code on a server, you can run it right on the browser, or on a NodeJS notebook (Jupyter like). Even though we loose performances with BigNumber, our algorithms are well-engineered and ensure decent performances on every device. You can use TheoremJS for every project, ranging from doing your math homework to launching a rocket into deep space. (Ok, maybe if you're planning to launch a rocket into space, you might want to use other tools in addition to TheoremJS).

    TinyColor

    TinyColor

    Fast, small color manipulation and conversion for JavaScript

    TinyColor is a microframework for inputting colors and outputting colors as different formats. Input is meant to be as permissive as possible. TinyColor is a small, fast library for color manipulation and conversion in JavaScript. It allows many forms of input, while providing color conversions and other color utility functions. It has no dependencies. The string parsing is very permissive. It is meant to make typing a color as input as easy as possible. All commas, percentages, parenthesis are optional, and most input allow either 0-1, 0%-100%, or 0-n (where n is either 100, 255, or 360 depending on the value). HSL and HSV both require either 0%-100% or 0-1 for the S/L/V properties. The H (hue) can have values between 0%-100% or 0-360. RGB input requires either 0-255 or 0%-100%.

    TodoMVC

    TodoMVC

    Helping you select an MV* framework

    TodoMVC is a project that helps developers choose an MV* framework by providing a structured way of comparing JS libraries and frameworks. These days there are so many MV* frameworks developers can choose from to structure and organize JavaScript web apps. TodoMVC helps developers navigate through this sea of choices on the basis of actual project code, so they can choose which one matches them and their needs best. TodoMVC has been called the 'Speed-dating' and 'Rosetta Stone' of MV* frameworks, however there may be more that certain frameworks are capable of. The best way to use TodoMVC is to invest time in researching its offered solutions in greater depth before opting for them.

    Tonic

    Tonic

    Easy to audit, zero-dependencies and build-tool-free

    A low-profile component framework. 1 file. 1 class. ~350 lines of code. No build tools are required. Native web components. Ideal for JAM stacks. Identical on client & server. Composition oriented. Event delegation by default. Lots of examples. Building a component with Tonic starts by creating a function or a class. The class should have at least one method named render which returns a template literal of HTML. onic is a thin wrapper around web components. Web components require a name with two or more parts. So your class name should be CamelCased (starting with an uppercase letter). Tonic has no templating language, it uses HTML! But since HTML only understands string values, we need some help to pass more complex values to a component, for that we use this.html. There is no evidence that Virtual DOMs improve performance across a broad set of use cases, but it's certain that they greatly increase complexity. Tonic doesn't use them. Instead, we recommend incremental updates.

    Tracing Framework

    Tracing Framework

    Web Tracing Framework libraries and extensions

    The Web Tracing Framework (WTF) is an open source suite of tools, libraries, and visualizers created by Google to help developers analyze and optimize the performance of complex web applications. By adding lightweight instrumentation to their code, developers can trace execution flow, identify bottlenecks, and detect performance regressions. The framework provides fine-grained insights into application behavior, making it particularly useful for achieving smooth, high-performance experiences, such as maintaining 60fps animations in web interfaces. It includes visualization tools that allow for detailed analysis of timing, resource usage, and event flow, enabling developers to diagnose and fix inefficiencies effectively. While still experimental, WTF is designed to be extensible and community-driven, encouraging contributions and adaptations for various types of web applications.

    TuiCss

    TuiCss

    Text-based user interface CSS library

    TuiCss is a library focused to create web applications using an interface based on ASCII table, like the old MS-DOS applications. This kind of interface is very legible because the ultra-contrast colors used and because the reduced effects used on the components in the view. The base of this project is Turbo Vision Framework, but some other frameworks were also checked to introduce some features to TuiCss, like curses, ncurses, Newt, etc. Check the examples page in the wiki to stay on top of some creations, or check the getting started page to start using this library! To start to use TuiCss in your project, you can just download the repository content and import the files that are in the dist folder with the html directives. Alternatively, you can install the package with NPM.

    TypeScript Koa Starter

    Koa with TypeScript's application generator. Creates a new typescript koa application. application is configured to use TypeScript instead of plain JavaScript. Node Js is great for the rapid development of web-projects, but is often neglected because of the lack of type safety. TypeScript solves this issue and (along with its linter file) can even make your code more robust than some other static languages like Java.
