I'm trying to render a template in Vue 3. The template contains a component, which is locally registered on the instance.
import template from './template'
import RenderlessPagination from "./RenderlessPagination";
import {h, resolveComponent} from 'vue'
export default {
name: 'Pagination',
components: {RenderlessPagination},
provide() {
return {
Page: () => this.value,
perPage: () => this.perPage,
records: () => this.records
}
},
render() {
const RLPagination = resolveComponent('renderless-pagination');
return h(RLPagination, {
slots: {
default: function (props) {
return props.override ? h(
props.override,
{
attrs: {props}
}
) : template(props)(h)
}
}
})
},
props: {
value: {
type: Number,
required: true,
validator(val) {
return val > 0;
}
},
records: {
type: Number,
required: true
},
perPage: {
type: Number,
default: 25
},
options: {
type: Object
}
},
data: function () {
return {
aProps: {
role: "button"
}
}
}
}
This results in a following run-time warning:
resolveComponent can only be used in render() or setup()
In addition the renderless-pagination
component is not compiled, but just added as-is to the HTML:
<renderless-pagination slots=[Object Object]></renderless-pagination>
As you can see I am using resolveComponent
in the render
function, which makes me wonder why it complains, and why the renderless-pagination
component is not compiled.
I checked the value returned from the resolveComponent
call, and it just returns the component's name, i.e renderless-pagination
.
What am I missing here?
EDIT:
Following @skirtle's comment I have removed the duplicate Vue instance from the package, using the externals
option in webpack
.
However, I am still receiving the same error:
resolveComponent can only be used in render() or setup()
Relavant webpack
config:
output: {
path: path.resolve(__dirname, './dist'),
publicPath: '/dist/',
filename: 'vue-pagination-2.min.js',
library:'Pagination',
libraryTarget: "commonjs"
},
externals: {
vue: {
root: 'Vue',
commonjs: 'vue',
commonjs2: 'vue',
amd: 'vue'
}
}
Thanks to @skirtle's comment I have removed the duplicate Vue instance but was still getting the same error.
What ended up working is passing the component instance itself to the
h
function, like so:I suppose that's what
resolveComponent
does behind the scenes... Oh,well
