Migrate from Polyglot.js to Intlayer

If you are using Airbnb's Polyglot.js, migrating to Intlayer is extremely straightforward using the compat layer.

What to do

Simply run the initialization command in your project:

npx intlayer init

This generates intlayer.config.ts. You can then utilize the bundler plugin alias to transparently redirect Polyglot imports to @intlayer/polyglot.

What it does under the hood

Polyglot.js syntax typically relies on polyglot.t('key', {name}) with %{name} interpolations and smart_count plurals separated by "singular |||| plural".

Under the hood:

• Interpolation: The compat layer handles %{var} placeholders natively.
• Plurals: The string is split at |||| and evaluated against native Intl.PluralRules according to the active locale, mirroring Polyglot's own bucket order per locale.
• Dictionaries: You bypass the need to provide huge JSON configurations to new Polyglot() – Intlayer handles the dictionaries dynamically and prunes them automatically.
