lift/framework

This system is the Lift web framework, a Scala-based toolkit for building web applications. It provides core infrastructure for asynchronous processing, HTTP request handling, and template rendering, while offering utilities for JSON, Markdown, and HTML manipulation. The codebase has been significantly refactored to modernize its build system, migrate to Jakarta Servlet APIs, and support Scala 2.13 and 3, while removing numerous legacy components and deprecated integrations.

How it got here

2009 · Legacy code and test cleanup

This period was dominated by the removal of deprecated and legacy components across the entire codebase, including old actor models, JSON parsing, and various widget implementations. The cleanup extended to test suites and build configurations, reflecting a broad effort to modernize the framework's architecture and eliminate outdated APIs.

2010–2011 · Lift 3.0 architecture and modernization

This period focused on the structural overhaul of the Lift framework for version 3.0, introducing a new actor system with asynchronous future support and migrating the codebase to Scala 3 and Jakarta EE standards. The work involved significant refactoring of the web and HTTP provider layers, alongside the addition of comprehensive test coverage and Java interop utilities.

2012–2026 · Scala 3 and modern Scala compatibility

This period focused on extending the Lift framework to support Scala 3 and modern Scala versions (2.12, 2.13, 3) through new implementations and comprehensive test coverage. It also introduced new features such as server-side JavaScript execution, flexible menu rendering, and Markdown parsing, alongside updating brand assets.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 7ea53e8dc2 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
