## Threads

`Prologue` supports two HTTP server: `httpbeast` and `asynchttpserver`. If you are in Linux or MacOS, use `--threads:on` to enable the multi-threads HTTP server. If you are in windows, `threads` should not be used. You can use `-d:usestd` to switch to `asynchttpserver` in Linux or MacOS.

## Benchmarking and debug

If you want to benchmark `prologue` or release your programs, make sure to set `settings.debug` = false.

```nim

let

# debug attributes must be false

env = loadPrologueEnv(".env")

settings = newSettings(appName = env.getOrDefault("appName", "Prologue"),

debug = false,

port = Port(env.getOrDefault("port", 8080)),

secretKey = env.getOrDefault("secretKey", "")

)

```

or in `.env` file, set `debug = false`.

```nim

# Don't commit this to source control.

# Eg. Make sure ".env" in your ".gitignore" file.

debug=false # change this

port=8080

appName=HelloWorld

staticDir=/static

secretKey=Pr435ol67ogue

```

## Disable logging

There are two ways to disable logging messages:

- set `settings.debug` = false

- set a startup event

```nim

proc setLoggingLevel() =

addHandler(newConsoleLogger())

logging.setLogFilter(lvlInfo)

let

event = initEvent(setLoggingLevel)

var

app = newApp(settings = settings, startup = @[event])

```

## Avoid using a function name which is same to the module name.

`src/index.nim`

```nim

proc index(ctx: Context) {.async.} =

...

```

## Use the full path of JS, CSS files.

For instance in your HTML file use `templates/some.js` instead of `some.js`.

## Run in async mode

The server can run in async mode, this is useful to perform other tasks beside

accepting connections.

```nim

import prologue

proc handler(ctx: Context) {.async.} =

resp "Hello world"

let settings = newSettings(port = Port(8000))

let app = newApp(settings)

app.all("/*$", handler)

waitFor app.runAsync()

```
