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 🙏

What does it look like?

// app/._index.tsx
import { ActionFunctionArgs, json, type MetaFunction } from '@remix-run/node';
import { Form, useActionData, useLoaderData } from '@remix-run/react';
import { useT } from 'remix-intl';
import { getT } from 'remix-intl/server';

export const meta: MetaFunction = ({ location }) => {
  const { t } = getT(location);
  return [{ title: t('title') }];
};

export default function Index() {
  const { locales } = useLoaderData<typeof loader>();
  const actionData = useActionData<typeof action>();
  const { t } = useT();

  return (
    <div>
      <h1>{t('create_todo')}</h1>

Configuration

1. Create files

Create i18n config file

app/i18n.ts

// app/i18n.ts
import { createInstance } from 'i18next';
import type { GetLocalesRes, GetMessagesRes, IntlConfig } from 'remix-intl/types';
import { setIntlConfig } from 'remix-intl/i18n';

const defaultNS = 'remix_intl';
const i18next = createInstance({ defaultNS, ns: [defaultNS], resources: {} });
i18next.init({
  defaultNS,
  ns: [defaultNS],
  resources: {},
});

async function getLocales(): Promise<GetLocalesRes> {
  // you can fetch dynamic locales from others API
  return { locales: ['zh-CN', 'en'] };
}

async function getMessages(locale: string, ns?: string): Promise<GetMessagesRes> {
  // you can fetch dynamic messages from others API
  const messages = await fetch(
    `http://localhost:5173/locales/${locale}/${ns || 'index'}.json`
  ).then((res) => res.json());
  return { messages, locale, ns };
}

export const intlConfig: IntlConfig = {
  mode: 'search',
  paramKey: 'lang',
  cookieKey: 'remix_intl',
  defaultNS,
  clientKey: 'remix_intl',
  defaultLocale: '',
  getLocales,
  getMessages,
  i18next,
};

setIntlConfig(intlConfig);

export default i18next;

Create i18n cookie file

app/i18n.server.ts

// app/i18n.server.ts
import { createCookie } from '@remix-run/node';
import { intlConfig } from './i18n';

export const i18nCookie = createCookie(intlConfig.cookieKey);

Create i18n navigation components file

app/navigation.tsx

// app/entry.client.tsx
import { RemixBrowser } from '@remix-run/react';

export function Layout({ children }: { children: React.ReactNode }) {

        {/* --- 4.ADD THIS END --- */}
      </body>
    </html>
  );
}

export default function App() {
  return <Outlet />;
}

Create i18n messages

public/locales/en/index.json

{
  "hi": "Hello"
}

public/locales/zh-CN/index.json

{
  "hi": "您好"
}

Usage

Different mode: segment or search

segment mode: https://example.com/locale/path

search mode: https://example.com/path?lang=locale

Default is search mode, you can update mode in app/i18n.ts config file.

If you choose segment mode, don't forget add file prefix ($lang). to your routes files

paramKey

Default is lang, you can change to others you like.

Switch different languages

No need refresh page example:

import { SwitchLocaleLink } from '~/navigation';

const langs = [
  {
    text: 'English',
    code: 'en',
  },
  {
    text: '简体中文',
    code: 'zh-CN',
  },
];

export default function LanguageSwitcher() {
  return (
    <div>
      {langs.map((item, idx) => {
        return (
          <SwitchLocaleLink key={item.locale} locale={item.code} query={{ idx }}>
            {item.text}
          </SwitchLocaleLink>
        );
      })}
    </div>
  );
}

Refresh page example:

import { SwitchLocaleLink } from '~/navigation';

const langs = [
  {
    text: 'English',
    code: 'en',
  },
  {
    text: '简体中文',
    code: 'zh-CN',
  },
];

export default function LanguageSwitcher() {
  return (
    <div>
      {langs.map((item) => {
        return (
          <SwitchLocaleLink reloadDocument key={item.locale} locale={item.code}>
            {item.text}
          </SwitchLocaleLink>
        );
      })}
    </div>
  );
}

Link, NavLink and useNavigate

import { Link, NavLink, useNavigate } from '~/navigation';

export default function LinkNavigate() {
  const navigate = useNavigate();
  return (
    <div>
      {/* /docs?lang=[locale] */}
      <Link to="/docs">Documents</Link>
      {/* /docs?lang=[locale] */}
      <NavLink to="/docs">Documents</NavLink>
      <button
        onClick={() => {
          /* /docs?lang=[locale] */
          navigate('/docs');
        }}>
        Go to Documents
      </button>
    </div>
  );
}

useT and useLocale

In React components, we can use useLocale to get current locale code,

and useT can get t function to translate:

import { useLocale, useT } from 'remix-intl';

export default function RemixIntlExample() {
  const locale = useLocale();
  const { t, locale: sameWithLocale } = useT();
  // or const { t,  locale: sameWithLocale } = useT(namespace);

  return (
    <div>
      <h1>{t('i18n_key')}</h1>
      <p>current locale: {locale}</p>
    </div>
  );
}

getT and getLocale in meta / loader / action

Out of react components, like inside meta, loader or action, we can use getT to get t function and translate:

import { getLocale, getT } from 'remix-intl/server';

// in `meta`
export const meta: MetaFunction = ({ location }) => {
  const { t, locale } = getT(location); // `getT` can receive location object or string pathname?search
  // or const { t, locale } = getT(location, namespace);
  const sameWithLocale = getLocale(location); // `getLocale` same paramater with `getT`

  return [{ title: t('i18n_key') }];
};

// in `loader`

export const loader = async ({ request }: LoaderFunctionArgs) => {
  const { t } = getT(request.url);
  const locale = getLocale(request.url);
  return json({ title: t('i18n_key'), locale });
};

// in `action`
export async function action({ request }: ActionFunctionArgs) {
  const body = await request.formData();
  const { t } = getT(request.url);
  if (!body.get('title')) {
    return json({ errors: { title: t('required') } });
  }
  return redirect(request.url);
}
