@jvlk/rescript-remix
ReScript bindings, modules, and functions for Remix.
Requires ReScript v11.
This is a work in progress and is not complete
Installation
npm install @jvlk/rescript-remixUpdate rescript.json to include it in your dependencies.
"bs-dependencies": [
"@jvlk/rescript-remix"
],If you want to have .res files directly in the app/routes directory you will need to set the file extension to .jsx in rescript.json.
Note: ReScript does not allow you to have
$in file names so you will need to create a JavaScript file for routes with params such asblog/$id.jsxand import from your generated JavaScript files.
Add ReScript extenstions to Remix's ignored files so it doesn't try and load them in as routes and uses the generated .jsx files.
// remix.config.js
export default {
ignoredRouteFiles: ["**/.*", "**/*.res", "**/*.resi"],
}root.js
You can add types to Remix's links and meta functions
@module("./style.css")
external styles: string = "default"
let links: Remix.Links.t = () => [Remix.Links.Href({rel: "stylesheet", href: styles})]
let meta: Remix.Meta.t = () => [
Remix.Meta.Content({name: "viewport", content: "width=device-width, initial-scale=1"}),
Remix.Meta.Title({title: "My site"}),
Remix.Meta.Content({
name: "description",
content: "a website",
}),
Remix.Meta.Charset({charset: "UTF-8"}),
]
@react.component
let make = () => {
<html lang="en">
<head>
<link rel="icon" href="data:image/x-icon;base64,AA" />
<Remix.Meta />
<Remix.Links />
</head>
<body>
<main>
<Remix.Outlet />
</main>
<Remix.Scripts />
<Remix.LiveReload />
</body>
</html>
}
let default = makeLoader
To create a typed loader you can use Remix.MakeLoader higher order module (functor). This will create a type for a loader as well as a typed useLoaderData hook that has a typed response.
// _index.res
module Data = {
type t = {posts: Posts.t} // type for the data returned by the loader
type params // route params
type context = { "NODE_ENV": string, "API_KEY": string } // context passed from the server
}
module Loader = Remix.MakeLoader(Data) // create a Loader module for this route
let loader: Loader.t /** use Loader.t to add typing to the exported loader function */= async ({context}) => {
let secret = context["API_KEY"]
let data = await Posts.query(secret)
Loader.json( // this is Remix's json function typed to Data.t
{posts: data}, // if this doesn't match Data.t you'll get a type error
~jsonOptions={
headers: { // you can add headers to the response
"Cache-Control": "max-age=300, s-maxage=3600",
},
},
)
}
@react.component
let make = () => {
let {posts} = Loader.useLoaderData() // the data from the hook is fully typed
<div>
{posts
->Array.map(post => <Post post />)
->React.array}
</div>
}
let default = make // you have to export make as default for route filesActions
To create an action you can use Remix.MakeAction.
module ActionData = {
type t
type context = Env.context
}
module Action = Remix.MakeAction(ActionData)
let action: Action.t = async ({context, request}) => {
/** */
Js.null // actions expect you to return a value or null
}
