            Cannot read property 'title' of null using vuejs 3
            Asked 2021-May-02 at 17:32

            i am new to vuejs3, i tried using json with vuejs3, i displayed the courses in view blog / index, and when clicking on a course in an index it redirect to details of that course clicks, in my case it gives me error: Uncaught (in promise) TypeError: Cannot read property 'title' of null.

            blog/index.vue

            ...

            ANSWER

            Answered 2021-May-02 at 17:32

            The problem is with your blog/show.vue file.

            Notice how in your data, post is set to null.

            When your component mounts, it attempts to read post.title and post.content but it fails because post does not yet contain those properties.

            The method to retrieve and set the post data is only run after the component has been mounted.

            One way would be to not display the

            and

            tags until post data is no longer null by using an attribute like v-if="post"

            Alternatively, you can set some default values to your post by making it an object:

            I'm using the excellent work of Robin Wieruch to understand how to make a call to an API Endpoint. Here's one of his projects: https://github.com/the-road-to-learn-react/react-hooks-introduction

            Shown below is a modified version of his useDataApiHook-example. With it I wired up two buttons, which then give me 3 ways to query an endpoint. I've chosen to use the same endpoint in all cases but have tested it with different endpoints and it seems to work fine.

            Suppose I don't want to call the query upon component load (and don't want a GET request going out upon load). How would one do that?

            You may pass an empty string to your hook and create a condition that fetch isn't triggered when API endpoint is empty:

            Fetching Reddit posts in React using Axios, weird JSON path
            Asked 2019-Jul-21 at 08:28

            I'm trying to get the titles of reddit posts from a subreddit in React, using Axios for fetching.

            I can fetch the JSON from here, and would like to get the data of each object (post/comment) separately (so I can show titles, post text and the like in the render() part of the component).

            Here's the first lines of that JSON, pretty-printed:

            ANSWER

            Answered 2019-Jul-21 at 08:28

            That's how axios parses the response json object. They store it under their own personal data key. It just so happens that within the json object provided by Reddit, they also have a field called data that holds the children array you want.

            It might be more helpful to name your variables like so:
