vue-router this.$route.params is empty

I'm trying to get a variable called project_id from the address bar using vue-router. I've initialized a router like so:

import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App'

Vue.config.productionTip = false
Vue.use(VueRouter)

/* eslint-disable no-new */
const router = new VueRouter({
  routes: [
    { path: '/project/:project_id', component: App }
  ]
})

new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

And tried to access this.$route.params.project_id from within my App.vue componenet:

<template>
  <div id="app">
    <img src="./assets/logo.png">
    <div id="center_bar">
      oh: {{this.$route.params.project_id}}
    </div>
  </div>
</template>

<script>
import ProjectList from './components/ProjectList'
import ProjectAboutBox from './components/ProjectAboutBox'

export default {
  name: 'App',
  created() {
    console.dir(this.$route.params)
  },
  components: {
    ProjectList,
    ProjectAboutBox
  }
}
</script>

However, when I write this.$route.params to the console, I see that it is an empty object.

I didn't see anyone who encountered something similar, so my guess is that I'm missing something very basic, but I can't figure out exactly what it is.

In addition, if I console.dir(this.$route) I'm seeing that fullPath is "/", even though I'm accessing http://localhost:8080/project/kljkjkj/

EDIT:

I have also found that when I create a <router-link> that leads to the address I want to parse, then clicking on it make the whole thing work, just accessing it directly by typing the address in the address bar fails

I come across a similar problem.

When manually enter url or refresh the browser, the $route object is not populated.

After some investigation, I found that if a lazy-loading route is matched:

For components outside 'router-view': the $route object is not being populated even in the 'mounted' hook, but is populated later in the rendering process.

For components inside 'router-view': the $route object is populated and available immediately

My fix is to use 'computed' property instead of 'data' when try to access variable inside the $route object.

Version: "vue": "^2.6.11", "vue-router": "^3.2.0"

Node: Changing the mode from 'hash' to 'history' doesn't help in my case.

Default vue-router is hash mode. You can try visit http://localhost:8080/#/project/kljkjkj/

You can change to history mode

const router = new VueRouter({
  mode: 'history',
  routes: [{ path: "/project/:project_id", component: App }]
});

when in <template>you don't need to refer this.

have you tried:

<template>
  <div id="app">
    <img src="./assets/logo.png">
    <div id="center_bar">
      oh: {{$route.params.project_id}}
    </div>
  </div>
</template>

?

Also, I see that you are not using a <router-view>:
