pathpida

pathpida

TypeScript friendly internal link client for Next.js and Nuxt.js.

Breaking change :warning:

2022/11/25

Since pathpida >= 0.20.0 , removed Sapper support.

2022/02/24

Since pathpida >= 0.18.0 , requires TypeSciprt 3.8 or higher for Type-Only Imports.

Features

• Type safety. Automatically generate type definition files for manipulating internal links in Next.js/Nuxt.js.
• Zero configuration. No configuration required can be used immediately after installation.
• Zero runtime. Lightweight because runtime code is not included in the bundle.
• Support for static files. Static files in public/ are also supported, so static assets can be safely referenced.
• Support for appDir of Next.js 13 Layout.

:warning: In the case of .vue file, Query/OptionalQuery type must not contain any reference types.

This is because due to typescript restrictions, types exported from .vue files cannot be imported in plugins/$path.ts. If you want to import types from other files, please use import types with absolute paths.

types/users.ts

export type UserId = number

pages/post/create.vue

<script lang="ts">
import Vue from "vue"

export type Query = {
  userId: import("~/types/users").UserId
  name?: string
}

export default Vue.extend({})
</script>
