Overseer

Overseer is a clojure web application which runs on the Jetty server. The site uses postgres for persistence.

Lein

You will need to get lein 2 installed and running.

To ensure you have the correct version, run: lein --version and verify that it is greater than 2.0.

Postgres

You will need a running postgres database on your system. Once that is complete, create a new database for overseer to use to run.

Profiles.clj

To run the site locally, you need to configure lein to pass the correct database connection settings to your running web site. To make this easier, lein allows for a file to be put in the same folder as the project.clj with machine-specific settings.

Make a file called profiles.clj in the base project directory. NEVER ADD IT TO GIT. Add in the following:

{
  :dev {:repl-options {:init-ns overseer.web}
        :migratus {:store :database
                  :migration-dir "migrations"
                  :db {:classname "org.postgresql.Driver",
                       :subprotocol "postgresql",
                       :user "USER",
                       :password "PASSWORD",
                       :subname "//localhost:5432/DATABASE"}}
        :dependencies [[clj-webdriver "0.7.2"]
                       [org.apache.httpcomponents/httpclient "4.3.5"]
                       [org.seleniumhq.selenium/selenium-java "2.48.1"]]
        :plugins [[com.jakemccrary/lein-test-refresh "0.23.0"]
                  [venantius/ultra "0.5.4"]]
        :env {:database-url "postgres://USER:PASSWORD@localhost:5432/DATABASE"
             :adminpass "web"
             :userpass "web"
             :host "0.0.0.0"
             :port "5000"
             :dev "true"
             :migratedb "true"
             :notify "false"
           }
        :jvm-opts ["-Duser.timezone=GMT"]
  }
}

Replace the following words in your profiles.clj:

• DATABASE - your desired local database name
• USER - your local postgres username
• PASSWORD - your local postgres username's password

Keep in mind that the assumed port number (5432) in the two connection strings is the postgres default. If your postgres uses a different port, you will need to change that too.

When starting with a new database, or when you want to "reset" your current database, set the key :newdb to true before you start the application. That will cause the database to be recreated empty, then some sample data be put inside it. CAUTION: leaving it set to true will cause it to drop EVERY TIME. You might want it true for the first time, then immediately set it to false after the application starts.

If you want to apply a new migration to an existing database, set the key :migratedb to true.

The application also sets up five default users for local testing. They are "admin", "super", "admin2", "user", and "demo". They all have the password "web". Typically, you will use "super" for local testing.

NPM

You will need to install Node.js and npm.

Running Locally

$ git clone https://github.com/steveshogren/overseer.git
$ cd overseer
$ npm install

To build the frontend and serve it while listening for changes, run make watch

To run the backend, run make start.

If both the frontend and backend are running, the app will be available at localhost:5000.

Logging

Exception and debugging logging can be added to the system via the log4j.properties in the src/ directory.

An example that logs all INFO messages to a file but only WARN to the console would look like this:

log4j.rootLogger=INFO, A1, CA

log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
log4j.appender.CA.Threshold = WARN

log4j.appender.A1=org.apache.log4j.RollingFileAppender
log4j.appender.A1.File=log/app.log
log4j.appender.A1.MaxFileSize=500MB
log4j.appender.A1.MaxBackupIndex=2
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p%c - %m%n
