Code Skeleton

App.vue – template code : use of v-model, v-on:click, interpolation syntax

<template>
  <div id="container">
    <h3>Weather app using Vue and Open Weather map API</h3>
    <input
      type="text"
      placeholder="Search..."
      v-model="searchQuery"
      class="search-input"
    />
    <div>
      <button v-on:click="callApi()">Submit</button>
    </div>
    <div class="weather-data" v-if="typeof weatherData.main != 'undefined'">
      <div class="desc">{{ todayDate }}</div>
      <div class="details">{{ Math.floor(weatherData.main.temp) }} °C</div>
      <div class="desc">
        Min Temp: {{ Math.floor(weatherData.main.temp_min) }} °C
      </div>
      <div class="desc">
        Max Temp: {{ Math.floor(weatherData.main.temp_max) }} °C
      </div>
      <div class="desc">
        {{ weatherData.weather[0].main }}
        ({{ weatherData.weather[0].description }})
      </div>
    </div>
  </div>
</template>

App.vue – script – use of JavaScript’s fetch() to call the API.

<script>
export default {
  name: "App",
  data() {
    return {
      searchQuery: "",
      base_url: "https://api.openweathermap.org/data/2.5/weather?q=",
      api_key: "3e51fac7d72844baf00526a323947c79",
      weatherData: {},
      todayDate: "",
    };
  },
  methods: {

    callApi() {
      let url = `${this.base_url}${this.searchQuery}${"&appid="}${
        this.api_key
      }${"&units=Metric"}`;
      console.log(url);
      fetch(url)
        .then((response) => response.json())
        .then((data) => this.setWeatherData(data));
    },

    setWeatherData(data) {
      this.weatherData = data;
      let todayDate = new Date();
      this.todayDate = `${todayDate.getDate()}${"/"}${todayDate.getMonth()}${"/"}${todayDate.getFullYear()}`;
    },
  },
};
</script>
