| [Authentication Basic](https://start.ktor.io/p/auth-basic) | Handles 'Basic' username / password authentication scheme |
## Building & Running
To build or run the project, use one of the following tasks:
| Task | Description |
|-------------------------------|----------------------------------------------------------------------|
| `./gradlew test` | Run the tests |
| `./gradlew build` | Build everything |
| `buildFatJar` | Build an executable JAR of the server with all dependencies included |
| `buildImage` | Build the docker image to use with the fat JAR |
| `publishImageToLocalRegistry` | Publish the docker image locally |
| `run` | Run the server |
| `runDocker` | Run using the local docker image |
If the server starts successfully, you'll see the following output:
```
2024-12-04 14:32:45.584 [main] INFO Application - Application started in 0.303 seconds.
2024-12-04 14:32:45.682 [main] INFO Application - Responding at http://0.0.0.0:8080

#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.
