VueJS dynamic routes and components

Question

Using cue-cli 3. Is it possible to do this (router.js):

axios.get( `${process.env.VUE_APP_API_DOMAIN}/wp-json/api/v1/routes`).then( r => r.data ).then(routes => {
    routes.pages.forEach( (e) => {
        router.addRoutes([
            {
                path: `/${e.slug}`,
                component: e.template,
            },
        ]);
    });
});

e.template is a string 'Default' and of course VueJS says: route config "component" for path: /privacy-policy cannot be a string id. Use an actual component instead. Tried with Vue.component(e.template) no luck.

What I want to do here is create dynamic routes based on XHR response.

Here is all router.js code:

import Vue from 'vue'
import Router from 'vue-router'
import Home from './views/Home.vue'
import Default from './views/Default.vue'
import Test from './views/Test.vue'
import axios from "axios";

Vue.use(Router);

const router = new Router({
  mode: 'history',
  base: process.env.BASE_URL,
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home
    },
  ]
});

axios.get( `${process.env.VUE_APP_API_DOMAIN}/wp-json/api/v1/routes`).then( r => r.data ).then(routes => {
    routes.pages.forEach( (e) => {
        router.addRoutes([
            {
                path: `/${e.slug}`,
                component: e.template,
            },
        ]);
    });
});

export default router;

Currently I ended up with this solution:

function getComponent(name) {

    let component = null;

    switch(name)
    {
        case 'Default':
            component = Default;
            break;

        case 'Test':
            component = Test;
            break;
    }

    return component;

}

axios.get( `${process.env.VUE_APP_API_DOMAIN}/wp-json/api/v1/routes`).then( r => r.data ).then(routes => {
    routes.pages.forEach( (e) => {
        router.addRoutes([
            {
                path: `/${e.slug}`,
                component: getComponent(e.template),
            },
        ]);
    });
});

Another one more cleaner solution:

const components = { Default, Test }

axios.get( `${process.env.VUE_APP_API_DOMAIN}/wp-json/api/v1/routes`).then( r => r.data ).then(routes => {
    routes.pages.forEach( (e) => {
        router.addRoutes([
            {
                path: `/${e.slug}`,
                component: components[e.template],
            },
        ]);
    });
});

If e.template stores the template string,

You should wrap it as one options object like {template: e.template, props: {}, data: function () {} }, then call Vue.extend to construct the component.

or you can ignore Vue.extend because Vue will call Vue.extend to construct the component automatically.

Check the usage at Vue Guide: Vue.component

Edit as the OP states e.tempate is one component name:

if e.template is the name of component, uses Vue.component(e.template).

Vue.config.productionTip = false
const router = new VueRouter({
  routes: [
  ]
})

Vue.component('test', {
  template: '<div>I am Predefined component -> {{index}}</div>',
  props: ['index']
})

let routerIndex = 1
setInterval(()=> {
  let newComponent = routerIndex%2 ? {template: '<div>I am User -> {{index}}</div>', props: ['index']} : Vue.component('test')
  
  router.addRoutes([{
    path: '/Test' + routerIndex,
    name: 'Test' + routerIndex,
    component: newComponent,
    props: { index: routerIndex }
  }])
  console.log('add route = ', '/Test' + routerIndex, ' by ', routerIndex%2 ? 'options object' : 'Vue.component')
  routerIndex++
}, 2000)

Vue.use(VueRouter)
app = new Vue({
  el: "#app",
  router,
  data: {
    routeIndex: 0
  },
  watch: {
    routeIndex: function (newVal) {
      this.$router.push({'name': 'Test'+newVal})
    }
  }
})

div.as-console-wrapper {
  height: 100px;
}

<script src="https://unpkg.com/[email protected]/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>
<div id="app">
    <p>Current Route Index: {{routeIndex}}</p>
    Test Route: <input v-model="routeIndex" type="number">
    <router-view></router-view>
</div>

Yes e.template is a string coming from backend, and I have tried: component: {template: e.template, props: {}, data: function () {} }, no avail.

RomkaLTU Over a year ago

Yes it's valid, but it;s string. id: 2 slug: "sample-page" template: "Test" title: "Sample Page" type: "page"

RomkaLTU Over a year ago

I mean e.template is a string of component name, not a Template HTML. For example e.template is 'Test' and component is imported like this: import Test from './views/Test.vue'

Sphinx Over a year ago

if so , change it Vue.component(e.template)

Tried that long time before posted this question :) It doesn't renders anything.
