How to add router with query param to router list? - vue.js

Question

I want to add a route with query params.
If the url is blog, then navigate to index page.
If the url includes the author query param, replace a component on the page with the BlogAuthorPage component.
router: {
extendsRoutes(routes, resolve) {
routes.push({
name: 'author-page-detail',
path: '/blog?author=*',
component: resolve(__dirname, 'pages/blog/author-page.vue')
})
}
}

Answer 1

This should not be done in nuxt.config.js's router key but rather in your blog.vue page directly with a component router guard.
The code below should be enough to check if the route does have a author query params and redirect to the blog/author-page page.
<script>
export default {
beforeRouteEnter(to, from, next) {
next((vm) => {
if (vm.$route.query?.author) next({ name: 'blog-author-page' })
else next()
})
},
}
</script>

I use "#nuxtjs/router": "^1.6.1",
nuxt.config.js
/*
** #nuxtjs/router module config
*/
routerModule: {
keepDefaultRouter: true,
parsePages: true
}
router.js
import Vue from 'vue'
import Router from 'vue-router'
import BlogIndexPage from '~/pages/blog/index'
import BlogAuthorPage from '~/pages/blog/author-page';
Vue.use(Router);
export function createRouter(ssrContext, createDefaultRouter, routerOptions, config) {
const options = routerOptions ? routerOptions : createDefaultRouter(ssrContext, config).options
return new Router({
...options,
routes: [
...options.routes,
{
path: '/blog',
component: ssrContext.req.url.includes('/blog?author') ? BlogAuthorPage : BlogIndexPage
}
]
})
}
