Raycast Effect

This library allows you to create Raycast Extensions using Effect.

Getting Started

1. Follow the "Create your first extension" guide
2. Convert to a module (because I don't know how to properly package Typescript packages, plz help).
   • Add "type": "module", to your package.json
   • Change module to node16 in tsconfig.json
   • Add "moduleResolution": "node16", in tsconfig.json
3. Create a ./src/lib/Runtime.ts file:

   import { NodeContext, NodeHttpClient } from "@effect/platform-node";
   import { Layer, ManagedRuntime } from "effect";
   import Raycast from "raycast-effect";
   
   // Compose your runtime here by adding services with Layer.merge
   export const Runtime = ManagedRuntime.make(
     pipe(Raycast.layer, Layer.merge(NodeContext.layer), Layer.merge(NodeHttpClient.layer)),
   );
   
   export const effectCommand = Raycast.command(Runtime);
   export const effectView = Raycast.view(Runtime);
   export const useEffectFn = Raycast.use(Runtime);

Creating Views

import { Effect } from 'effect'
import { effectView, useEffectFn } from './lib/Runtime.js'
import { LaunchProps, Arguments, Detail } from '@raycast/api'

export default effectView(
  Effect.fn(
    function* (params: LaunchProps<{ arguments: Arguments.ViewCommand }>) {
      // define a callback
      const callback = useEffectFn(
        Effect.fn(function* (/* define some arguments */) {
          // do some stuff
        },
          // Catch callback errors here with Effect.catchTag
        )
      )

      // return a view here
      return <Detail />
    },
    // Catch errors here with Effect.catchTag
  )
)

Creating Commands

import { Toast } from "@raycast/api";
import { effectCommand } from "./lib/Runtime.js";
import { Effect } from "effect";
import Raycast from "raycast-effect";

export default effectCommand(
  Effect.fn(
    function* () {
      const now = new Date();
      yield* Raycast.Clipboard.copy(now.toLocaleDateString());
      yield* Raycast.Feedback.showHUD("Copied date to clipboard");
    },
    Effect.catchTag("@raycast/ClipboardError", (e) =>
      Raycast.Feedback.showToast({
        title: "Something went wrong...",
        message: e.message,
        style: Toast.Style.Failure,
      }),
    ),
  ),
);
