Getting Started with Vue.js

This integration guide is following the Getting started guide. We assume that you have completed Step 8 and therefore can consume the API by browsing this url.

If you haven't gone through the getting started guide, the way you request a Strapi API with Vue.js 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.

vue create vue-app

Use an HTTP client

Many HTTP clients are available but in this documentation we'll use Axios and Fetch

:::: tabs

::: tab axios

yarn add axios

::: tab fetch

No installation needed

GET Request your collection type

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
