Diamond is a powerful full-stack web-framework written in the D Programming Language.

Diamond can be used to write powerful websites, webapis or as stand-alone as a template parser.

Key-Features

Key features of Diamond

Goals

  • To provide a powerful consistent API
    • The API of Diamond should be rich of features, but still with powerful performance and the style should be consistent all over.
  • High performance without complexity
    • The performance of Diamond should be high without making the API complex to use.
  • Compile-time template parsing
    • Templates are parsed at compile-time and thus produce very little run-time overhead.
  • Easy-to-use and feature-rich template syntax
    • The syntax of templates should be feature-rich, with an easy-to-use syntax.
    • It should be easy to create advanced templates without complex looking code.
  • Secure & less error-prone API
    • The API of Diamond should provide security to battle error-prone code, enabling code to be written "bug-free".
  • Enterprise development
  • Diamond should be stable enough and have enough features to be used in enterprise and commercial work.
  • Always free & open-source
    • Diamond should always remain free and open-source, no matter the framework's size or popularity.
  • As little dependencies as possible
    • The less dependencies Diamond has, the better.
    • library dependencies for database drivers etc. are okay
  • Cross-platform
    • Should always be able to support all platforms that vibe.d/DMD supports.
  • Natural development feeling
    • Using Diamond should feel natural without annoyance, so you can focus more on developing your application, rather than setting up Diamond.

Dependencies

Package Version Description
vibe.d 0.8.3 Used as the backend for Diamond's web applications. From 3.0.0 vibe.d will be an optional dependency.
DMD/Phobos 2.072.2 - 2.077.0 The standard library of D and thus a required dependency.
Mysql-native 2.2.1 A native wrapper for Mysql. It's a dependency, because of the MySql ORM.
ddbc X.X.X A database wrapper in D to a lot of database systems. Diamond will be using it for PostgreSQL, Sqlite and MSSQL.

2.10.0+ is generally backward compatible, but 3.0.0 is not.

Currently supported versions: 2.10.0 - 3.0.0

No longer supported (Only available in release.): < 2.10.0

Note: 3.0.0 is not yet supported, but the master branch is 3.0.0
