Vue.js Pattern for Async Requests: Using Renderless Components

Lukas Hermann on August 04, 2019

Most Vue apps need asynchronous HTTP requests and there are many ways to realize them: in the mounted() lifecycle hook, in a method triggered by a ... [Read Full]

Hey, I wanted to introduce this in project in my work. Is this solution working well with post, delete and put requests? My project is really complex. Does it scale well?

 

You might be interested in my article about this very same topic (funnily enough also inspired by the same podcast episode): Building Renderless Components to Handle CRUD Operations in Vue.js

 

Whoooa, good solution.

I am trying to reproduce your solution and a question has come up. my goal is to pass data torouter-view, I am now passing as props, but I do not know if it is the best solution?

On each page I have a variable corresponding to the page that will work this data.

Do you have any suggestions?

question

Passing props to <router-view> is fine in my opinion!

ty :p

a problem occured. On some pages, the props data is expected to be an object, but on others it is an array.

I thought I'd give the property multiple types, or is there a better solution?

Solution

props: {
    data: Object | Array
},
 

I read your article several months ago. Great content. I even sent the link to my coworkers! Although I was affraid to introduce it to our code.
Now I have found another post and started to think about it more seriously.
But probably I will use it in a new project.

 

This is awesome and a really smart solution! Have you tried this with server-side form validation?

Thanks! No, haven't used this extensively myself yet.

 

I am only using it with get requests. post and put tend to have additional validation steps which I usually do the regular way.
As for scaling: using the renderless component with get requests scales exceptionally well. It works just as well for small components as for really large lists with many parameters and changing options.

 
 

Great article. Thanks!

Just one point - I think we should start to use Vue.js Function API to wrap this logic as described here:

Thanks! As soon as the first early version of Vue 3 is available I will update this article with the new syntax.

 

You might want to use multiple words for a component name.

This recommendation is considered essential as a means to prevent conflicts with existing and future HTML elements (since all HTML elements are a single word):

Lukas,

Great article, I have a quick question. You advocate doing your API calls in the mounted() hook. I've always read that you should kick off async stuff in created(). Your thoughts?

Hi Ken,

in fact, I don't know myself which one is better, mounted or created hook. I pretty much picked one at random :)
