## What it is
T3 is a minimal, unopinionated client-side JavaScript framework from Box for building large-scale web applications with loosely-coupled components (services, modules, and behaviors). It is explicitly deprecated as of 2018, with Box having migrated to React and webpack.

## Use cases
- structure large-scale client-side JavaScript applications
- build loosely-coupled frontend components without MVC
- maintain legacy Box T3-based web applications
- combine a lightweight component framework with jQuery or Backbone
- enforce explicit dependencies between frontend modules

## When to choose
- you are maintaining an existing codebase already built on T3
- you want a tiny, unopinionated component structure alongside libraries like jQuery or Backbone

## When to avoid
- starting any new project, since the framework is deprecated and unsupported
- you need modern tooling, React integration, or ongoing community support
- you want a full-featured MVC or state-management solution

## Facets
- artifact type: framework
- maturity: abandoned
- function: frontend-framework, state-management
- domain: web-development, frontend, developer-tools
- platform: browser
- tags: component-based, loose-coupling, deprecated, client-side, modular-architecture, javascript
