A server may want to respond to a request that originated from htmx differently than a regular request. One way htmx can provide the same feel as a Single Page Application (SPA) is by swapping out the `body` content (or an element within it) instead of reloading the entire page. In this case, the developer can provide a partial layout to be used for these responses, while returning the full page for regular requests. The `IsHtmx` property makes this easy...
```fsharp
// "partial" and "full" are handlers that return the contents;
// "view" can be whatever your view engine needs for the body of the page
let result view : HttpHandler =
// "partial" and "full" are handlers that return the contents;
// "view" can be whatever your view engine needs for the body of the page
let result view : HttpHandler =
fun next ctx ->
match ctx.Request.IsHtmx && not ctx.Request.IsHtmxRefresh with
| true -> partial view
| false -> full view
if ctx.Request.IsHtmx && not ctx.Request.IsHtmxRefresh then
partial view
else
full view
```
htmx also utilizes [response headers](https://htmx.org/docs/#response_headers) to affect client-side behavior. For each of these, this library provides `HttpHandler`s that can be chained along with the response. As an example, if the server returns a redirect response (301, 302, 303, 307), the `XMLHttpRequest` handler on the client will follow the redirection before htmx can do anything with it. To redirect to a new page, you would return an OK (200) response with an `HX-Redirect` header set in the response.
```fsharp
let theHandler : HttpHandler =
let theHandler : HttpHandler =
fun next ctx ->
// some interesting stuff
withHxRedirect "/the-new-url" >=> Successful.OK
// some interesting stuff
withHxRedirect "/the-new-url" >=> Successful.OK
```
Of note is that the `HX-Trigger` headers can take either one or more events. For a single event with no parameters, use `withHxTrigger`; for a single event with parameters, or multiple events, use `withHxTriggerMany`. Both these have `AfterSettle` and `AfterSwap` versions as well.

@ -57,10 +60,10 @@ _(As `hx-boost="true"` is the usual desire for boosting, `_hxBoost` implies true
Some attributes have known values, such as `hx-trigger` and `hx-swap`; for these, there are modules with those values. For example, `HxTrigger.Load` could be used in the example above, to ensure that the known values are spelled correctly. `hx-trigger` can also take modifiers, such as an action that only responds to `Ctrl`+click. The `HxTrigger` module has a `Filter` submodule to assist with defining these actions.
```fsharp
let shiftClick =
let shiftClick =
p [ _hxGet = "/something"; _hxTrigger (HxTrigger.Filter.Shift HxTrigger.Click) ] [
str "hold down Shift and click me"
]
str "hold down Shift and click me"
]
```
If you want to load htmx from unpkg, `Htmx.Script.minified` or `Htmx.Script.unminified` can be used to load the script in your HTML trees.

_Note that htmx 2.0 is a BETA release. The [migration guide](https://v2-0v2-0.htmx.org/migration-guide-htmx-1/) does not currently specify any request or response header changes. This means that, as of this release, there are no required code changes in moving to this major version._

```fsharp

let myHandler : HttpHander =
fun next ctx ->

| Some prompt -> ... // do something with the text the user provided
| None -> ... // no text provided
match ctx.HxPrompt with

fun next ctx ->
// some meaningful work
withHxPushUrl "/some/new/url" >=> [other handlers]
// some meaningful work
withHxPushUrl "/some/new/url" >=> [other handlers]
```
The `HxSwap` module has constants to use for the `HX-Reswap` header. These may be extended with settle, show, and other qualifiers; see the htmx documentation for the `hx-swap` attribute for more information.

- `HxRequest` has a `Configure` function, which takes a list of strings; the other functions in the module allow for configuring the request.

```
- `HxTrigger` is _(by far)_ the most complex of these modules. Most uses won't need that complexity; however, complex triggers can be defined by piping into or composing with other functions. For example, to define an event that responds to a shift-click anywhere on the document, with a delay of 3 seconds before firing:
```fsharp
HxTrigger.Click
|> HxTrigger.Filter.Shift
|> HxTrigger.FromDocument
|> HxTrigger.Delay "3s"
