This option allows specifying the methods for locale detection as follows:\n\n```typescript\ntype LocaleDetector = (\"pathname\" | \"domain\" | \"cookie\" | \"browser\")[];\n\nconst localeDetector: LocaleDetector = [\"pathname\", \"domain\", \"cookie\", \"browser\"];\n```\n\nIf `pathname` is specified, the locale will be automatically detected based on the URL pathname.\n\nThe default value of `localeDetector` will vary depending on the `strategy` value to maintain backward compatibility. For instance, when `no_prefix` is selected, the default value would be:\n\n```javascript\nlocaleDetector: [\"domain\", \"cookie\", \"browser\"]\n```\n\n##### Example Configuration for My Use Case:\n\n```javascript\nstrategy: \"no_prefix\",\nlocaleDetector: [\"pathname\", \"cookie\", \"browser\"]\n```\n\nThis configuration would resolve the issue by enabling locale detection based on pathname while maintaining backward compatibility with existing behavior.\n\nThank you for considering this feature request. I would be happy to provide further clarifications or contribute to the implementation if needed.\n\n\n### Additional information\n\n- [x] Would you be willing to help implement this feature?\n- [ ] Could this feature be implemented as a module?\n\n### Final checks\n\n- [x] Read the [contribution guide](https://nuxt.com/docs/community/contribution) (The contribution guideline of nuxt-modules/i18n is compliant with Nuxt too).\n- [x] Check existing [discussions](https://github.com/nuxt-modules/i18n/discussions) and [issues](https://github.com/nuxt/nuxt/issues).",[3041],{"name":3019,"color":3020},3609,"Add `localeDetector` option to customize locale detection during Vue component rendering","2025-05-16T18:51:35Z","https://github.com/nuxt-modules/i18n/issues/3609",0.70901054,{"description":3048,"labels":3049,"number":3051,"owner":3022,"repository":3023,"state":3024,"title":3052,"updated_at":3053,"url":3054,"score":3055},"### Environment\n\n- Operating System: Darwin\n- Node Version: v22.15.0\n- Nuxt Version: 3.17.3\n- CLI Version: 3.25.1\n- Nitro Version: 2.11.12\n- Package Manager: npm@10.9.2\n- Builder: -\n- User Config: compatibilityDate, devtools, modules, i18n, nitro\n- Runtime Modules: @nuxt/content@3.5.1, @nuxtjs/i18n@9.5.4\n- Build Modules: -\n\n\n### Reproduction\n\nA minimal reproduction of this issue can be found in the following repository: https://github.com/odan-sandbox/nuxt-content-and-i18n-no_prefix-example\n\n\n### Describe the bug\n\nWhen using the `no_prefix` strategy in `nuxt-i18n`, the locale detection based on the URL pathname is not functioning as expected. This results in incorrect locale assignment during SSR/SSG.\n\nFor example, accessing `/en/about` and `/ja/about` should render the corresponding locale-specific content, but instead, both paths are rendered using the default or server locale, ignoring the locale information in the pathname.\n\nThis issue causes problems for multilingual documentation sites using `nuxt/content`, where the content is structured by locale (e.g., `docs/en/about.md`, `docs/ja/about.md`). During SSG, both paths may be generated with the same language content, leading to incorrect output.\n\nIf a PR to resolve this issue is considered appropriate, I would be willing to work on it.\n\n\n### Additional context\n\nRelated: https://github.com/nuxt-modules/i18n/issues/3609\n\n### Logs\n\n```shell\n\n```",[3050],{"name":3019,"color":3020},3619,"Locale detection not working with `no_prefix` strategy","2025-05-19T06:13:27Z","https://github.com/nuxt-modules/i18n/issues/3619",0.7227181,{"description":3057,"labels":3058,"number":3060,"owner":3022,"repository":3023,"state":3024,"title":3061,"updated_at":3062,"url":3063,"score":3064},"### Environment\n\n- Operating System: `Darwin`\n- Node Version: `v22.14.0`\n- Nuxt Version: `3.17.6`\n- CLI Version: `3.25.1`\n- Nitro Version: `2.11.13`\n- Package Manager: `npm@10.9.2`\n- Builder: `-`\n- User Config: `compatibilityDate`, `devtools`, `modules`, `i18n`\n- Runtime Modules: `@nuxtjs/i18n@9.5.6`\n- Build Modules: `-`\n\n\n### Reproduction\n\n[https://github.com/ap-arto/define-i18n-route-issue](https://github.com/ap-arto/define-i18n-route-issue)\n \n1.
