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 🙏

React Error Boundary, provider, and hooks for the MONICA browser SDK

Readme

@ah-monica/react

@ah-monica/browser の React adapter。Error Boundary・Provider・hooks を足すだけで、 transport と queue は browser SDK のものをそのまま使う。

対応環境

React ^18.0.0 || ^19.0.0(peer 依存)。@ah-monica/browser が動く browser 環境。

インストール

npm install @ah-monica/browser @ah-monica/react

初期化

client は @ah-monica/browser の createBrowserClient() で作り、MonicaProvider に 渡す。client の options(dsn や environment など)は @ah-monica/browser を参照。

import { createBrowserClient } from "@ah-monica/browser";
import { MonicaErrorBoundary, MonicaProvider } from "@ah-monica/react";

const monica = createBrowserClient({
  dsn: import.meta.env.VITE_MONICA_DSN,
  environment: "production",
});

export function Root() {
  return (
    <MonicaProvider client={monica}>
      <MonicaErrorBoundary fallback={<p>画面を表示できません</p>}>
        <App />
      </MonicaErrorBoundary>
    </MonicaProvider>
  );
}

使い方

MonicaErrorBoundary

render 中のエラーを捕まえて送り、fallback を描く。

| prop | 型 | 説明 | | --- | --- | --- | | children | ReactNode | 保護する subtree | | fallback | ReactNode \| (error: Error) => ReactNode | エラー後に描くもの。省略時は何も描かない | | client | MonicaBrowserClient | 使う client。省略すると MonicaProvider のものを使う | | onError | (error, info) => void | 送信とは別に呼ばれる |

client も Provider も無い場合は送信しない(fallback と onError は動く)。

captureReactException

既存の Error Boundary から呼ぶ。

componentDidCatch(error: Error, info: ErrorInfo) {
  void captureReactException(this.props.client, error, info.componentStack ?? "");
}

component stack は contexts.react.componentStack、tag は integration: "react" で 送る。

useMonica / useMonicaCapture

const monica = useMonica(); // MonicaProvider の client。外で呼ぶと例外
const capture = useMonicaCapture({ tags: { feature: "bots" } });

capture(error, { tags: { action: "open" } });

useMonicaCapture() は既定の capture context と呼び出し時の context を合成して captureException() を呼ぶ。tags と contexts は浅くマージし(呼び出し側が優先)、 breadcrumbs は既定のあとに呼び出し側を繋ぐ。level は呼び出し側が優先。 それ以外の field(user / request / fingerprint)は呼び出し側があればそちらで 置き換える。

送信結果と診断

拒否された送信の扱いは @ah-monica/browser と同じ。onDiagnostic と flush() の戻り値の読み方は TROUBLESHOOTING.md。
