Code Comparison

i18n-ally configuration example:

{
  "i18n-ally.localesPaths": ["locales"],
  "i18n-ally.keystyle": "nested",
  "i18n-ally.sortKeys": true
}

Additional Notes

Both repositories appear to be the same project, as lokalise/i18n-ally is likely a mirror or fork of the original i18n-ally extension. The comparison provided focuses on the features and characteristics of i18n-ally itself, as there are no significant differences between the two repositories.

i18n-ally is a popular extension for managing internationalization in VS Code, offering a wide range of features to streamline the localization process. It supports various file formats and frameworks, making it versatile for different project types. However, its limitation to the VS Code environment and potential complexity for new users should be considered when choosing an i18n solution.

Pros of vue-i18n

• Specifically designed for Vue.js applications, offering seamless integration
• Supports pluralization and datetime localization out of the box
• Lightweight and easy to set up for Vue projects

Cons of vue-i18n

• Limited to Vue.js ecosystem, not suitable for other frameworks or vanilla JavaScript
• Fewer advanced features compared to i18n-ally, such as machine translation integration
• Less extensive IDE support and visual tools for managing translations

Code Comparison

vue-i18n:

import Vue from 'vue'
import VueI18n from 'vue-i18n'

Vue.use(VueI18n)

const i18n = new VueI18n({
  locale: 'en',
  messages: {
    en: { hello: 'Hello' },
    ja: { hello: 'こんにちは' }
  }
})

i18n-ally:

import i18n from 'i18next'
import { initReactI18next } from 'react-i18next'

i18n
  .use(initReactI18next)
  .init({
    resources: {
      en: { translation: { hello: 'Hello' } },
      ja: { translation: { hello: 'こんにちは' } }
    },
    lng: 'en'
  })

While vue-i18n is tailored for Vue.js applications, i18n-ally offers a more versatile solution that can be used across different frameworks and vanilla JavaScript projects. i18n-ally provides more advanced features and better IDE integration, but vue-i18n excels in simplicity and Vue-specific optimizations.

Pros of i18next

• Mature and widely adopted internationalization framework
• Extensive ecosystem with plugins and integrations
• Supports complex pluralization and nesting

Cons of i18next

• Steeper learning curve for beginners
• Configuration can be complex for advanced use cases

Code Comparison

i18next:

import i18next from 'i18next';

i18next.init({
  lng: 'en',
  resources: {
    en: {
      translation: {
        key: 'Hello world!'
      }
    }
  }
});

console.log(i18next.t('key')); // Output: Hello world!

i18n-ally:

import { createI18n } from 'vue-i18n'

const i18n = createI18n({
  locale: 'en',
  messages: {
    en: {
      key: 'Hello world!'
    }
  }
})

console.log(i18n.global.t('key')); // Output: Hello world!

i18next is a standalone library that can be used with various frameworks, while i18n-ally is primarily focused on Vue.js integration. i18next offers more flexibility and features for complex internationalization needs, but i18n-ally provides a simpler setup for Vue.js projects. Both libraries support basic translation functionality, as shown in the code examples.

Pros of go-i18n

• Specifically designed for Go applications, offering seamless integration
• Supports pluralization and ordinal rules out of the box
• Lightweight and efficient, with minimal dependencies

Cons of go-i18n

• Limited to Go language, unlike i18n-ally's multi-language support
• Lacks advanced features like machine translation and collaboration tools
• No visual interface for managing translations

Code Comparison

go-i18n:

import "github.com/nicksnyder/go-i18n/v2/i18n"

bundle := i18n.NewBundle(language.English)
localizer := i18n.NewLocalizer(bundle, "en")

message := localizer.MustLocalize(&i18n.LocalizeConfig{
    MessageID: "greeting",
    TemplateData: map[string]string{"Name": "Alice"},
})

i18n-ally (Vue.js example):

<template>
  <div>{{ $t('greeting', { name: 'Alice' }) }}</div>
</template>

<script>
import { useI18n } from 'vue-i18n'

export default {
  setup() {
    const { t } = useI18n()
    return { t }
  }
}
</script>

Both libraries offer straightforward ways to implement internationalization, but go-i18n is more Go-centric, while i18n-ally provides a more versatile solution for various programming languages and frameworks.

Pros of Polyglot.js

• Lightweight and simple to use, with a small footprint
• Supports pluralization and interpolation out of the box
• Easy integration with JavaScript and Node.js projects

Cons of Polyglot.js

• Limited features compared to more comprehensive i18n solutions
• Lacks advanced functionalities like automatic language detection or context-aware translations
• No built-in support for managing translation files or workflows

Code Comparison

Polyglot.js:

import Polyglot from 'polyglot.js';

const polyglot = new Polyglot();
polyglot.extend({greeting: 'Hello, %{name}!'});
console.log(polyglot.t('greeting', {name: 'John'}));

i18n-ally:

import { useI18n } from 'vue-i18n';

const { t } = useI18n();
console.log(t('greeting', {name: 'John'}));

Summary

Polyglot.js is a lightweight and straightforward internationalization library, ideal for simple projects or when minimal overhead is desired. It provides basic i18n features like pluralization and interpolation.

i18n-ally, on the other hand, is a more comprehensive solution with advanced features such as automatic language detection, context-aware translations, and built-in support for managing translation files. It's better suited for larger projects or those requiring more complex internationalization workflows.

The choice between the two depends on the project's specific needs, with Polyglot.js being simpler to implement but less feature-rich, while i18n-ally offers more advanced capabilities at the cost of increased complexity.

Pros of formatjs

• Extensive documentation and wide community adoption

Cons of formatjs

• Steeper learning curve due to its extensive feature set
• Heavier bundle size compared to simpler i18n solutions
• Primarily focused on JavaScript/React ecosystems

Code Comparison

$t('welcome_message', { name: 'John' })

formatjs:

<FormattedMessage
  id="welcome_message"
  defaultMessage="Welcome, {name}!"
  values={{ name: 'John' }}
/>
