How it got here

2013 · Ecto API expansion and tooling

This period focused on expanding Ecto's capabilities with support for window functions, a new query API, and advanced ordering options. The team also introduced dedicated Mix tasks and generators for database management and repository scaffolding, while significantly increasing test coverage for core components and tasks.

2014–2015 · Ecto modularization and test expansion

This period focused on refactoring Ecto's internal architecture by splitting large modules like Ecto.Adapter and Ecto.Query.Builder into specialized, modular components. The team simultaneously expanded test coverage across query building, repository operations, and association handling to ensure the new structure was robust and correct.

2016–2023 · Ecto API and example modernization

This period focused on modernizing the Ecto codebase by introducing dedicated modules for schema loading and metadata management, replacing ad-hoc structures with robust, typed structs. Concurrently, the Friends example application was refactored to align with current Elixir and Ecto best practices, while new reference guides were added to document associations and CRUD operations.

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 5 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 6c0c457be6 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
