Getting Started with Vue.js

This integration guide is following the Quick Start Guide. We assume that you have fully completed its "Hands-on" path, and therefore can consume the API by browsing this url (opens new window).

If you haven't gone through the Quick Start Guide, the way you request a Strapi API with Vue.js (opens new window) remains the same except that you will not fetch the same content.

Create a Vue.js app

Create a basic Vue.js application using Vue CLI (opens new window).

vue create vue-app

Use an HTTP client

Many HTTP clients are available but in this documentation we'll use Axios (opens new window) and Fetch (opens new window).

yarn add axios

No installation needed

GET Request your collection type

Execute a GET request on the restaurant Collection Type in order to fetch all your restaurants.

Be sure that you activated the find permission for the restaurant Collection Type.

Example GET request with axios

import axios from 'axios';

axios.get('http://localhost:1337/restaurants').then(response => {
  console.log(response);
});

Example GET request with fetch

fetch('http://localhost:1337/restaurants', {
  method: 'GET',
  headers: {
    'Content-Type': 'application/json',
  },
})
  .then(response => response.json())
  .then(data => console.log(data));

Example response

[
  {
    "id": 1,
    "name": "Biscotte Restaurant",
    "description": "Welcome to Biscotte restaurant! Restaurant Biscotte offers a cuisine based on fresh, quality products, often local, organic when possible, and always produced by passionate producers.",
    "created_by": {

      "username": null
    },
    "updated_by": {
      "id": 1,
      "firstname": "Paul",

    "updated_at": "2020-07-31T11:37:16.975Z",
    "categories": [
      {
        "id": 1,
        "name": "French Food",
        "created_by": 1,
        "updated_by": 1,
        "created_at": "2020-07-31T11:36:23.164Z",
        "updated_at": "2020-07-31T11:36:23.172Z"
      }
    ]
  }
]

Example

./src/App.vue

<template>
  <div id="app">
    <div v-if="error">
      {{ error }}
    </div>
    <ul v-else>
      <li v-for="restaurant in restaurants" :key="restaurant.id">
        {{ restaurant.name }}
      </li>
    </ul>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  name: 'App',
  data () {
    return {
      restaurants: [],
      error: null
    }
  },
  async mounted () {
    try {
      const response = await axios.get('http://localhost:1337/restaurants')
      this.restaurants = response.data
    } catch (error) {
      this.error = error;
    }
  }
}
</script>

./src/App.vue

<template>
  <div id="app">
    <div v-if="error">
      {{ error }}
    </div>
    <ul v-else>
      <li v-for="restaurant in restaurants" :key="restaurant.id">
        {{ restaurant.name }}
      </li>
    </ul>
  </div>
</template>

<script>

export default {
  name: 'App',
  data () {
    return {
      restaurants: [],
      error: null,
      headers: {'Content-Type': 'application/json'}
    }
  },
  methods: {
    parseJSON: function (resp) {
      return (resp.json ? resp.json() : resp);
    },
    checkStatus: function (resp) {
      if (resp.status >= 200 && resp.status < 300) {
        return resp;
      }
      return this.parseJSON(resp).then((resp) => {
        throw resp;
      });
    }
  },
  async mounted () {
    try {
      const response = await fetch("http://localhost:1337/restaurants", {
        method: 'GET',
        headers: this.headers,
      }).then(this.checkStatus)
        .then(this.parseJSON);
      this.restaurants = response
    } catch (error) {
      this.error = error
    }
  }
}
</script>

POST Request your collection type

Execute a POST request on the restaurant Collection Type in order to create a restaurant.

Be sure that you activated the create permission for the restaurant Collection Type and the find permission for the category Collection type.

In this example a japanese category has been created which has the id: 3.

Example POST request with axios

import axios from 'axios';

axios
  .post('http://localhost:1337/restaurants', {
    name: 'Dolemon Sushi',
    description: 'Unmissable Japanese Sushi restaurant. The cheese and salmon makis are delicious',
    categories: [3],
  })
  .then(response => {
    console.log(response);
  });

Example POST request with fetch

fetch('http://localhost:1337/restaurants', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    name: 'Dolemon Sushi',
    description: 'Unmissable Japanese Sushi restaurant. The cheese and salmon makis are delicious',
    categories: [3],
  }),
})
  .then(response => response.json())
  .then(data => console.log(data));

Example response

{
  "id": 2,
  "name": "Dolemon Sushi",
  "description": "Unmissable Japanese Sushi restaurant. The cheese and salmon makis are delicious",
  "created_by": null,
  "updated_by": null,
  "created_at": "2020-08-04T09:57:11.669Z",
  "updated_at": "2020-08-04T09:57:11.669Z",
  "categories": [
    {
      "id": 3,
      "name": "Japanese",
      "created_by": 1,
      "updated_by": 1,
      "created_at": "2020-07-31T11:36:23.164Z",
      "updated_at": "2020-07-31T11:36:23.172Z"
    }

PUT Request your collection type

Execute a PUT request on the restaurant Collection Type in order to update the category of a restaurant.

Be sure that you activated the put permission for the restaurant Collection Type.

We consider that the id of your restaurant is 2. and the id of your category is 2.

Example PUT request with axios

import axios from 'axios';

axios
  .put('http://localhost:1337/restaurants/2', {
    categories: [2],
  })
  .then(response => {
    console.log(response);
  });

Example PUT request with fetch

fetch('http://localhost:1337/restaurants/2', {
  method: 'PUT',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    categories: [2],
  }),
})
  .then(response => response.json())
  .then(data => {
    console.log(data);
  });

Example response

{
  "id": 2,
  "name": "Dolemon Sushi",
  "description": "Unmissable Japanese Sushi restaurant. The cheese and salmon makis are delicious",
  "created_by": null,
  "updated_by": null,
  "created_at": "2020-08-04T10:21:30.219Z",
  "updated_at": "2020-08-04T10:21:30.219Z",
  "categories": [
    {

      "name": "Brunch",
      "created_by": 1,
      "updated_by": 1,
      "created_at": "2020-08-04T10:24:26.901Z",

    }
  ]
}

Conclusion

Here is how to request your Collection Types in Strapi using Vue.js. When you create a Collection Type or a Single Type you will have a certain number of REST API endpoints available to interact with.

We just used the GET, POST and PUT methods here but you can get one entry, get how much entry you have and delete an entry too. Learn more about API Endpoints.
