## Run the code

All the code blocks can be copied and used directly (they are actually tested Python files).

To run any of the examples, copy the code to a file `main.py`, and start `fastapi dev` with:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>

plugins {
  kotlin("jvm")
  id("com.github.johnrengelman.shadow")
}

tasks.compileJava {
  options.isWarnings = false
}

tasks.jar {
  manifest {
    attributes("Main-Class" to "okhttp3.sample.SampleServer")
  }
}

dependencies {
  implementation(projects.mockwebserver)
}

tasks.shadowJar {
  mergeServiceFiles()
