Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Adapter for using pico-di with Remix + express.

npm version Socket


pico-di を Remix + express 環境で使うためのアダプタです。

Features

pico-di-remix-express には pico-di に加えて以下の機能があります:

  • action / loader インジェクション
  • リクエスト毎のスコープ
  • シングルトンサービスの対応
    • ライブリロードできます
    • (開発ビルドにおいて) リクエスト間であってもシングルトンサービスがシングルトンであることを保証します

Installation

Remix + express (@remix-run/express) に対応しています。

Node.js

npm から入手できます。インストールするには:

$ npm install pico-di-remix-express

Usage

サービスは全て ~/services ディレクトリ以下にまとめ、~/services/index.ts でそれぞれインポートします。プロバイダ作成関数をエクスポートする必要があります。

// /app/services/index.ts

import { createGetProvider } from "pico-di-remix-express";
import Service1 from "./Service1";
import Service2 from "./Service2";
import Service3 from "./Service3";

type Context = {
	service1: Service1,
	service2: Service2,
	service3: Service3,
};

// `getProvider` という名前にしておきます。
const getProvider = createGetProvider<Context>(builder => builder
	.addSingleton("service1", Service1)
	.addScoped("service2", Service2)
	.addTransient("service3", Service3));

export {
	getProvider,
	type Context,
	type Service1,
	type Service2,
	type Service3,
}

/app/entry.server.tsx の修正

先ほどの getProvider という関数を ~/entry.server.tsx からエクスポートする必要があります。このエクスポートは pico-di-remix-express がサービスプロバイダを取得するために必要です。

// /app/entry.server.tsx

export { getProvider } from "~/services";

// ...

/server.js の修正

action / loader でサービスを使う

import { type LoaderArgs, type ActionArgs } from "pico-di-remix-express";
import { type Context } from "~/services";

export const loader = ({
	context: {
		service1,
		service2,
		service3,
	},
}: LoaderArgs<Context>) => {
	// ...
};

export const action = ({
	context: {
		service1,
		service2,
		service3,
	},
}: ActionArgs<Context>) => {
	// ...
};
