    window.location.reload();
   });
  }
 }
};
</script>

helper.js

export const server = {
 baseURL: 'http:localhost:3000'
}

main.js

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

Vue.config.productionTip = false

new Vue({
 router,
  render: h => h(App)
}).$mount('#app')

I expect that enough info and you can help me to fix them

Answer 1

Use string template to build your url correctly like below;

axios.delete(`${server.baseURL}/blog/delete?postID=${id}`).then(data => {

Then server and id will be used and errors will be fixed.
