Installation

npm i remix-easy-mode zod

Usage

Resource Route

import type { DataFunctionArgs } from "@remix-run/server-runtime"
import { dataFunctionHelper, useAction } from "remix-easy-mode"
import { z } from "zod"

const schema = z.object({
  someUserInput: z.string(),
})

// this is like a TRPC procedure
export const action = (ctx: DataFunctionArgs) => {
  return dataFunctionHelper({
    ctx,
    schema,
    bouncer: async ({ ctx, csrfToken }) => {
      // (1) throw error or (2) return user session
    },
    fn: async ({ input, session }) => console.log({ input, session }), // typesafe!,
  })
}

// return hook from your resource route to use on client
export function useExample() {
  return useAction<typeof action, typeof schema>({
    path: "/resource-route",
    schema,
    onSuccess: (res) => console.log(res), // typesafe!,
  })
}

Client-side Form

import { InputHelper } from "remix-easy-mode"
import { useExample } from "./resource-route"
import { StyledInput } from "./your-custom-input-component"

export default function Index() {
  const { Form, fields } = useExample()

  return (
    <div>
      <Form
        csrfToken="whatever" // optional
        onSuccess={(res) => console.log(res)} // typesafe!
      >
        <InputHelper {...fields.someUserInput.props} component={StyledInput} />

        <button>Submit</button>
      </Form>
    </div>
  )
}
