Presets
See src/presets.
TypeScript
In order to properly hint types for auto-imported APIs
|
AutoImport({
dts: true // or a custom path
}) |
ESLint
π‘ When using TypeScript, we recommend to disableno-undefrule directly as TypeScript already check for them and you don't need to worry about this.
If you have encountered ESLint error of no-undef:
|
AutoImport({
eslintrc: {
enabled: true, // <-- this
},
}) |
|
// .eslintrc.js
module.exports = {
extends: [
'./.eslintrc-auto-import.json',
],
} |
FAQ
Compare to unimport
From v0.8.0, unplugin-auto-import uses unimport underneath. unimport is designed to be a lower-level tool (it also powered Nuxt's auto import). You can think unplugin-auto-import is a wrapper of it that provides more user-friendly config APIs and capabilities like resolvers. Development of new features will mostly happen in `unimport`` from now.
Compare to vue-global-api
You can think of this plugin as a successor to vue-global-api, but offering much more flexibility and bindings with libraries other than Vue (e.g. React).
Pros
- Flexible and customizable
- Tree-shakable (on-demand transforming)
- No global population
Cons
- Relying on build tools integrations (while
vue-global-apiis pure runtime) - but hey, we have supported quite a few of them already!
