 # @vintl/nuxt

+## 1.9.1
+
+### Patch Changes
+
+- a26c360: Switch to the official Nuxt module template
+
+  This should resolve any issues with our Nuxt-specific imports, e.g., breakage of the Nuxt injections (added through `provide`s in plugins) due to the invalid `Plugin` type specified by our package (sorry for that!).
+
+## 1.9.0
+
+### Minor Changes
+
+- efdcdb9: Replaced Zod validation with a much simpler normalization and assertion 🚀
+
+  This brings a huge TypeScript performance boost for both maintainers and users of the module.
+
+  Developers using the module will also be happy to discover that each option is now documented (they always were, but documentation was erased from Zod inferred types by TypeScript) and each type used in options can be exported if you need to programatically extend the options.
+
+  Better yet? Common mistakes are still checked and pretty printed!
+
+  See the full explanation for decision to switch from Zod in the commit message.
+
+  🐞 If you stumble upon a bug caused by this switch, please [report them on issue tracker](https://github.com/vintl-dev/nuxt/issues).
+
+### Patch Changes
+
+- 9e42c63: Fixed a typo in message about message that cannot be parsed
+
+## 1.8.1
+
+### Patch Changes
+
+- 114d04a: Switched to a slightly more compatible `#app` augmentation
+
+## 1.8.0
+
+### Minor Changes
+
+- 9d939c1: Switched to using module ID markers
+
+  Previously VIntl for Nuxt kept track of files that were used as locale messages and matched module IDs based on them. This, however, was very unreliable in certain environments.
+
+  With this change VIntl for Nuxt now uses ‘markers’, URL parameters added to the end of imported module IDs. This allows it to very quickly test whether a specific module is imported through a message file and should be processed by the VIntl unplugin.
+
+## 1.7.1
+
+### Patch Changes
+
+- 6479891: VIntl updated to the latest version
+
+  Latest version of VIntl fixes missing type declarations for global properties, like `$t`, `$fmt` and `$i18n`.
+
+  We might add automatic handling for disabling of `controllerOpts.globalMixin` in the future releases. You can follow the status update in [#74](https://github.com/vintl-dev/nuxt/issues/74).
+
+  For now, if you disable global mixin, use the below augmentation to disable these unusable properties:
+
+  ```ts
+  declare global {
+    namespace VueIntlController {
+      interface Options {
+        globalMixin: false
+      }
+    }
+  }
+  ```
+
+## 1.7.0
+
+### Minor Changes
+
+- a9fdc59: Add support for parsing the messages in the error handlers
+
+  With [update to `@vintl/unplugin`](https://github.com/vintl-dev/unplugin/releases/tag/v1.5.0), it's now possible to use `parseMessage` from the error handler's context to parse custom messages or re-parse the current message with any modified options.

Sasha Sorokin	c2eabcef76	Fix TypeScript error about usage of `noEmit` Composite files are not allowed to use `noEmit`, however, we need to prevent TypeScript from compiling the files, as this would override JS files (in our case, eslint.config.mjs). Seems this can be avoided by emitting declarations only. It's not like were actually going to use TSC to build the project...	2024-06-18 13:29:31 +02:00

Sasha Sorokin	624ab8eeff	Export ModuleOptions for Nuxt module builder Without it, Nuxt module builder will attempt to generate the types manually and this obviously is not going to work, because the module project doesn't have a valid Nuxt VIntl configuration, and even if it did, the type would be inferred from this configuration rather than using the actual type. I suppose this was done to fix the issue where they previously inferred the type based on extends TypeScript comparison on the returned module, which would fail in some odd cases because the dependency and Nuxt weren't in sync, so they used different "Module" per se.	2024-06-18 12:32:28 +02:00

Alexander Sorokin	efdcdb988e	Replace Zod with a much simpler normalization and assertion Zod, despite being a somewhat okay library to perform parsing of inputs and their validation, is very tolling on the TypeScript performance. It also bugs TypeScript into emitting huge declarations with erased documentation. Unfortunately, the way this project used Zod to perform parsing, validation and transformation of input module options, has been so tolling on performance that TypeScript language server couldn't keep up anymore and started crashing due to heap errors. The suggestions in editor took seconds to show up. This is a terrible developer experience that made it significantly harder to maintain the project. We could've of course looked into the performance bottlenecks, but I believe it will be only a temporary remedy. TypeScript is just not built for types of such complexity. This is why this commit fully replaces Zod with a much simpler approach to normalization and assertion. Unlike Zod, it's very error prone, and you can cast some incompatible values to any to cause a crash, however I believe most developers won't do that and will use TypeScript. Some of the simple and common assertions are still preserved, so common mistakes will still be caught. If you remember, when you had any errors with your options, you would get Zod validation errors pretty-printed in console. Fear not, this commit also takes care of that and implements pretty printing of the assertion errors. Additional benefit of removing Zod is that all JSDoc documentation is now fully preserved, which means every single option is documented and you no longer have to open the documentation site. You also should be able to import types, normalizers and assertion functions from `@vintl/nuxt/options` in case need doing so arises.	2023-11-25 16:45:07 +01:00

Alexander Sorokin	9d939c1b1b	Switch to using module ID markers Previously VIntl for Nuxt kept track of files that were used as locale messages and matched module IDs based on them. This, however, was very unreliable in certain environments. With this change VIntl for Nuxt now uses 'markers', URL parameters added to the end of imported module IDs. This allows it to very quickly test whether a specific module is imported through a message file and should be processed by the VIntl unplugin.	2023-11-14 04:03:39 +01:00
