Kit

Lightweight, modular framework for scalable production systems.

Goal

The goal of Kit is to provide a template for a robust, scalable Clojure web application. It hides common plumbing that is standard across projects via its libs system, while exposing code that tends to be customized in the template.

Thanks to integrant, and aero, the libs are simple skeletons with the bulk of the customization being done in the system configuration EDN file.

Quick start

The recommended way to create a new Kit application is using deps-new.

Using neil (recommended):

brew install babashka/brew/neil
neil new io.github.kit-clj/kit yourname/app

Or directly with deps-new:

clojure -Sdeps '{:deps {io.github.seancorfield/deps-new {:mvn/version "RELEASE"}}}' \
  -Tnew create :template io.github.kit-clj/kit :name yourname/app

Libs

• kit-core - basic utility functions used by some other libs
• kit-xtdb - Simple binding to connect to a XTDB database node
• kit-hato - HTTP client using hato
• kit-nrepl - nREPL component for use in a running system. e.g. to connect to a production REPL
• kit-metrics - Configurable metrics using iapetos
• kit-quartz - Scheduler using cronut as an integrant binding for quartz. Exposes the cronut API, simply some extensions for aero and utilities
• kit-redis - An extension of core.cache for Redis via carmine
• kit-repl - Socket REPL integrant binding for use in a running system. e.g. to connect to a production REPL
• kit-selmer - Templating configuration with selmer
• kit-sql - Deprecated. Use kit-sql-conman and kit-sql-migratus. Pulls in both of these as generic SQL integrant binding. Uses conman , next.jdbc , hugsql, and migratus directly, or implicitly
• kit-sql-conman - Uses conman , next.jdbc , hugsql,
• kit-sql-hikari - General sql layer, just contains connection pooling ( via hikari-cp) and jdbc wrapper ( via next.jdbc) .
• kit-sql-migratus - uses migratus for SQL migrations
• kit-postgres - lib with data bindings and utilities for working with Postgres
• kit-mysql - lib with data bindings and utilities for working with MySQL8+
• kit-undertow - Server binding via ring-undertow-adapter

Build Tool Support

Presently only Clojure deps is supported, however there are plans to add Leiningen support.

Emacs Integration

An emacs package is available which provides a Magit-style interface to clj-new and deps-new and provides a command to create Kit web applications.

Inspiration and thanks to

• integrant as the basis of the project
• aero for powerful configuration used throughout
• re-frame template for code used directly in kit-template
• Luminus framework from which the initial project that Kit's predecessor was built upon
