React: user-uploaded pics?

Folks, I’m working on a blog in React, kind of a WordPress clone, I guess, and I want users to be able to upload pictures. Any basic ideas on how to do this?

I’m thinking the form to make a post should have an input form, maybe something like this?

<input type="file" name="myImage" accept="image/*" />

But then how would that be stored in React? I’m thinking the form submission should create an <Image src="{image} alt="image /> thing that will go in the <Post />.

Also, the picture will eventually be stored in the Firebase Real-Time database that the blog is hooked up to. If you want to look at what I have so far, it’s here:


Hey there,

great work so far!

I think some better questions are:

  • Why do I want to store it in React?
  • Does that make sense?

I’m thinking the form submission should take data, put it somewhere, and the presentation layer, e.g. a React component, should render an output from the data.

Thanks, I think you’re right! I had been coding this in a pattern:

  1. store it in the component
  2. refactor it to store it in the App
  3. refactor it to store it in the database

trying to do it in steps so I had control every step. This worked fine for strings and numbers, but maybe it’s not viable in this case.

I managed to get it hooked directly up to Firebase storage and have got it more or less working locally.

Alright, that makes sense!

You should put an onChange function to your file input and then store it in the state.

// say we have [files,setFiles] state

// That is if you want to preview the image to the user.
// [image,setImage] state

You can then store that file state in firebase, they have a detailed documentation on this on their storage documentation.

Thanks, I’ll read that more carefully and give it a try.
