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 Intl Tools

A package that provides components to simplify working with react-intl.

Add internationalization and localization capabilities to your React app in 4 simple steps:

  • Wrap your main app with the react-intl-tools' <LocaleContextProvider>
  • Use react-intl's APIs (formatMessage(), <FormattedMessage />, etc) as you would normally
  • Extract and compile your messages with formatjs' extract and compile methods
  • Call react-intl-tools' setLocale() method to update the language

Table of Contents

Installation

  • npm install react-intl-tools

Setup and usage

react-intl-tools comes with two main utilities:

  • LocaleContextProvider is simply a wrapper around <ReactIntl.Provider> component. It takes two props:
    • defaultLocale a string that specifies the default locale to use
    • translations an object that contains the available translations
  • LocaleContext provides a locale string and setLocale(activeLocale) method for working with the active (currently selected) locale.

Using react-intl-tools is as simple as:

  • Wrapping your main app with the LocaleContextProvider and
  • Calling the setLocale() method returned by LocaleContext to update (or switch) the locale.

Example setup

// File: app.js

import React from "react"
import { LocaleContext } from "react-intl-tools"

function App() {
  const { setLocale } = React.useContext(LocaleContext);

  return (
    <div>
      <nav>
        <select value="en" onChange={(e) => setLocale(e.target.value)}>
          <option value="">Select Language</option>
          <option value="en">English</option>
          <option value="fr">French</option>
          <option value="de">German</option>
        </select>
      </nav>

      // Rest of app code goes here
    </div>
  )
}


// File: index.js

import ReactDOM from "react-dom"
import { LocaleContextProvider } from "react-intl-tools"
import App from "./app";

import en from "path/to/translations/en.json"
import fr from "path/to/translations/fr.json"
import de from "path/to/translations/de.json"

const translations = {
  en,
  fr,
  de,
}

ReactDOM.render(
  <LocaleContextProvider defaultLocale="en", translations={translations}>
    <App />
  </LocaleContextProvider>,
  document.getElementById("root")
)

Using the built-in LocaleSelector

react-intl-tools also comes with a <LocaleSelector> dropdown component that you can use in lieu of implementing your own locale switching mechanism.

If your locale switcher is going to be a dropdown (that is, a <select> element), you can use the LocaleSelector component instead.

Let's re-write our app.js file from the previous example to use the LocaleSelector component.

// File: app.js

import React from "react"
import { LocaleSelector } from "react-intl-tools"

const supportedLanguages = [
  { code: "en", name: "English" },
  { code: "fr", name: "French"  },
  { code: "de", name: "German"  },
];


function App() {
  return (
    <div>
      <nav>
        <LocaleSelector languages={supportedLanguages} selectorText="Choose language" />
      </nav>

      // Rest of app code goes here
    </div>
  )
}

Running the examples

  • Run npm run examples
  • Navigate to http://localhost:8080

If you wish to use a different port, use webpack's --port option: npm run examples -- --port PORT
