How to Display Posts from Your Ghost Blog on a Vue CLI Project Using the API

Working with APIs can be daunting, especially when trying to integrate them into your favorite frameworks. If you’re using Vue CLI and want to display posts from your Ghost Blog, things might get a bit tricky. This guide will break down how to pull posts from your Ghost blog using its API and effectively showcase them in a Vue project.

The Initial Challenge

You may be encountering issues getting your posts to display in your Vue application. While the Ghost API works seamlessly within a Nuxt environment or Node context, it can encounter hiccups when used with Vue. Specifically, trying to fetch the posts in the data function could lead to unexpected behavior due to the asynchronous nature of API calls.

The Common Mistake

Here's an example of how you might initially approach the problem:

The crucial point here is that getPosts() returns a promise that is still pending at the time of accessing it in the data function. This results in resultado being assigned a promise rather than the resolved posts.

The Solution: Lifecycle Hooks

Fortunately, there’s a simple fix! You can shift your API call to a Vue lifecycle hook, which is designed for executing code at specific points in the instance's lifecycle.

Step-by-Step Implementation

Setup the Data Function

Initialize your component's data with an empty or null value for resultado. This is where your posts will eventually be stored once they're fetched.

Use the Created or Mounted Hook

Here, we will use the created or mounted lifecycle hook. This allows you to run the asynchronous function to get posts right after the Vue instance has been created or mounted.

With this setup, your Vue instance will first create an empty state for resultado, and then it will fetch and assign the posts once they become available.

Displaying the Posts

After fetching the posts, you can easily render them in your template using the Vue v-for directive. The final setup will look something like this:

Conclusion

Integrating your Ghost Blog’s posts into a Vue CLI project is manageable with a proper understanding of asynchronous operations and lifecycle hooks. By fetching your posts within the created or mounted hooks rather than attempting to resolve them in the data function, you'll be able to display your content without any issues.

Remember, always keep an eye on promises and their resolved values when working with APIs in JavaScript! Happy coding!
