A functional ReScript server framework for Javascript runtimes. Currently supports Express and Bun.
Inspired and heavily based on Dream for OCaml.
npm i @jvlk/rescript-dreamModify your project's rescript.json file.
{
"bs-dependencies": [
+ "@jvlk/rescript-dream"
]
}You might also want some JSX bindings to support returning HTML from the server. You can use any JSX bindings you like, but I recommend @jvlk/rescript-lite-jsx.
Check out the example folder for more examples, but here's a basic server with HTMX.
let router = Dream.router([
Dream.get("/", async _ => {
Dream.html(
<html>
<head>
<script src="https://unpkg.com/htmx.org@1.9.12" />
</head>
<button hxGet="/data" hxTarget="#data"> {Lite.string("Get data")} </button>
<div id="data" />
</html>,
)
}),
Dream.get("/data", async _ => {
Dream.html(<div> {"Data!"->Lite.string} </div>)
}),
])
// You can also use DreamExpress.run
let _ = DreamBun.run(router->Dream.logger)
