Luminus-Template

A Leiningen template for projects using Luminus.

The template initializes a base Luminus application.

Requirements

Luminus requires Leiningen version 2.5.3+

Usage

The Luminus template ships out of the box with your latest Leiningen. Run the following command to create a new Luminus project which uses the default profile template:

lein new luminus <your project name>

However, if you would like to attach further functionality to your template you can append profile hints for these extended features:

Profile	Category	Description	Compare
+aleph	server	adds the Aleph server	diff
+http-kit	server	adds the fast HTTP Kit web server to the project	diff

+war	misc	adds support of building WAR archives for deployment to servers such as Apache Tomcat (should NOT be used for Immutant apps running on WildFly)	diff
+site	misc	creates template for site using the specified database (H2 by default) and ClojureScript	diff
+kibit	misc	adds lein-kibit plugin	diff
+servlet	misc	adds middleware for handling Servlet context	diff
+basic	misc	generates a bare bones luminus project	diff
+async	misc	support for async (= 3 argument) ring handlers

To add a profile simply pass it as an argument after your application name, e.g.:

lein new luminus myapp +cljs

You can also mix multiple profiles when creating the application, e.g.:

lein new luminus myapp +auth +postgres

To build as a executable Java ARchive (JAR) standalone, run the following command:

lein uberjar

Or if using the +boot profile:

boot uberjar

To run the resulting standalone executable .jar file, do as you would with any other:

user$ java -jar target/myapp.jar
15-Sep-14 16:06:21 APc47d.4f39.65e6.uhn.ca INFO [myapp.handler] -
-=[myapp started successfully]=-
16:06:21.685 INFO  [org.projectodd.wunderboss.web.Web] (main) Registered web context /
15-Sep-14 16:06:21 APc47d.4f39.65e6.uhn.ca INFO [myapp.core] - server started on port: 3002

Performance Testing

The app can be stress tested by running the Apache benchmark command:

ab -c 10 -n 1000 http://127.0.0.1:3000/

The memory and CPU usage can be inspected by running either jconsole or jvisualvm and attaching them to a running Luminus server.

Async Ring Handlers

Using async ring handlers is possible but adds another layer of complexity. If things go wrong you'll see a blank screen, possibly without any error message.

The server (undertow, jetty, servlet) and every middleware in the chain has to support async request handling.

To enable: add :async? true to your config maps.

Tested combinations:

• default (undertow)
• +war
• +servlet +war (this implies jetty9): http://localhost:3000/your-ns instead of just /
• +jetty +war: http://localhost:3000/your-ns instead of just /
• +jetty: works
• +http-kit
• +aleph
