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

@ -57,18 +60,20 @@ _(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"
]
```
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.

This package enables server-side support for [htmx](https://htmx.org) within [Giraffe](https://giraffe.wiki) and ASP.NET's `HttpContext`.
**htmx version: 2.0.3**
_Upgrading from v1.x: the [migration guide](https://htmx.org/migration-guide-htmx-1/) does not currently specify any request or response header changes. This means that there are no required code changes in moving from v1.* to v2.*._

withHxPush "/some/new/url" >=> [other handlers]
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.
### Learn
The naming conventions of this library were selected to mirror those provided by htmx. The header properties become `Hx*` on the `ctx.Request.Headers` object, and the response handlers are `withHx*` based on the header being set. The only part that does not line up is `withHxTrigger*` and `withHxTriggerMany`; the former set work with a single string (to trigger a single event with no arguments), while the latter set supports both arguments and multiple events.

This package enables [htmx](https://htmx.org) support within the [Giraffe](https://giraffe.wiki) view engine.
**htmx version: 2.0.3**
_Upgrading from v1.x: see [the migration guide](https://htmx.org/migration-guide-htmx-1/) for changes_
### Setup
1. Install the package.
@ -12,7 +16,7 @@ This package enables [htmx](https://htmx.org) support within the [Giraffe](https
Following Giraffe View Engine's lead, there are a set of attribute functions for htmx; for many of the attributes, there are also helper modules to assist with typing the values. The example below utilizes both:
```fsharp
let autoload =
let autoload =
div [ _hxGet "/this/data"; _hxTrigger HxTrigger.Load ] [ str "Loading..." ]
```
@ -21,29 +25,39 @@ Support modules include:
- `HxHeaders`
- `HxParams`
- `HxRequest`
- `HxSwap`
- `HxSwap` (requires `open Giraffe.Htmx`)
- `HxTrigger`
- `HxVals`
There are two `XmlNode`s that will load the htmx script from unpkg; `Htmx.Script.minified` loads the minified version, and `Htmx.Script.unminified` loads the unminified version (useful for debugging).
This also supports [fragment rendering](https://bitbadger.solutions/blog/2022/fragment-rendering-in-giraffe-view-engine.html), providing the flexibility to render an entire template, or only a portion of it (based on the element's `id` attribute).
### Learn
htmx's attributes and these attribute functions map one-to-one. The lone exception is `_hxBoost`, which implies `true`; use `_hxNoBoost` to set it to `false`. The support modules contain named properties for known values (as illustrated with `HxTrigger.Load` above). A few of the modules are more than collections of names, though:
htmx's attributes and these attribute functions map one-to-one. There are two exceptions:
- `_hxBoost` implies `true`; use `_hxNoBoost` to set it to `false`.
- `_hxSwapWithTransition` renders the standard `hx-swap` attribute and appends `transition:true` to the specified swap value.
The htmx `hx-on` attribute supports multiple events if they are separated with a newline (`\n`) character. The value provided to this attribute will be attribute-escaped, but in testing, it was interpreted correctly.
The support modules contain named properties for known values (as illustrated with `HxTrigger.Load` above). A few of the modules are more than collections of names, though:
- `HxRequest` has a `Configure` function, which takes a list of strings; the other functions in the module allow for configuring the request.
```fsharp
HxRequest.Configure [ HxRequest.Timeout 500 ] |> _hxRequest
HxRequest.Configure [ HxRequest.Timeout 500 ] |> _hxRequest
```
- `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"
|> _hxTrigger
HxTrigger.Click
|> HxTrigger.Filter.Shift
|> HxTrigger.FromDocument
|> HxTrigger.Delay "3s"
|> _hxTrigger
// or
// or
(HxTrigger.Filter.Shift >> HxTrigger.FromDocument >> HxTrigger.Delay "3s") HxTrigger.Click
|> _hxTrigger
(HxTrigger.Filter.Shift >> HxTrigger.FromDocument >> HxTrigger.Delay "3s") HxTrigger.Click
|> _hxTrigger
```
