So, To demonstrate this loader function. we will create a component for login or register and then send a request to the server. while sending a request to the server we will show a loader animation or image on the page of login. so let's start.

Step: 1 Create a Login or Register component

Here I create login component 

Login.vue

<template>
  <div >
    
     <div v-if="loading">
      <!-- here put a spinner or whatever you want to do when request is on proccess -->
      <div ></div>
    </div>

    <div v-if="!loading" >
      <div >
        <div >
          <div >Login vue</div>

          <div >
            <form>
              <div >
                <label for="email" >E-Mail Address</label>

                <div >
                  <input id="email" type=email v-bind: v-model="email" required autofocus>
                  <small >{{ error }} </small>
                </div>
              </div>

              <div >
                <label for="password" >Password</label>

                <div >
                  <input id="password" type=password v-model="password" required>
                  <router-link :to="{ name: 'email' }" >Forget Your Password ?</router-link>
            
                </div>
              </div>
              <div >
                <div >
                  <button type=submit @click="handleSubmit">
                    Login
                  </button>
                </div>
              </div>
            </form>
          </div>
        </div>
      </div>
    </div>
  </div>
</template>

After that add CSS code for Loader image.

 <style type=text/css>
        .js #loader { display: block; position: absolute; left: 100px; top: 0; }
        .se-pre-con {
            position: fixed;
            left: 0px;
            top: 0px;
            width: 100%;
            height: 100%;
            z-index: 99;
            background: url("//wpamelia.com/wp-content/uploads/2018/11/ezgif-2-6d0b072c3d3f.gif") center no-repeat #fff;
        }
    </style>

Add Vue Code

<script>
 
    export default {
        data(){
            return {
                email : "",
                password : "",
                error    : "",
                loading: false,
                name: 'vue-title',
                props: ['title'],
            }
        },
        methods : {
            handleSubmit(e) {
                e.preventDefault()
                if (this.password.length > 0){
                     this.loading = true ;
                    axios.post('api/login', {
                        email: this.email,
                        password: this.password
                      }).then((response) => {
                        
                        let is_admin = response.data.user.is_admin
                        localStorage.setItem('user',JSON.stringify(response.data.user))
                        localStorage.setItem('jwt',response.data.token)
                        this.loading = false;
                        if (localStorage.getItem('jwt') != null){
                            this.$emit('loggedIn')
                            if(this.$route.params.nextUrl != null){
                                this.$router.push(this.$route.params.nextUrl)
                            }
                            else {
                                if(is_admin== 1){
                                    this.$router.push('admin')
                                }
                                else {
                                    
                                    this.$router.push('dashboard')
                                }
                            }
                        }
                      })
                      .catch(error => {
                        console.error(error);
                        this.loading = false
                        if (error.response.status == 401){
                            this.error = error.response.data.error
                        }
                      });
