How to Upload a File on Shopify
From creating videos and optimizing images, to uploading photos and editing 3D models, Shopify apps manage media for all sorts of reasons. If you're developing an app that allows merchants or customers to interact with media, it's likely y'all'll need to implement a feature for uploading media files.
I recently started working on an app to majority manage collection images, and discovered there were many factors to consider, but virtually of the development work went into handling uploads. At that place are a number of steps to implement, including accepting files, storage, and validation. Non to mention upload performance.
With whatever app, allowing users to upload files is generally complicated. There'due south a whole host of concerns, and if the file is simply existence passed along to an API, it tin can feel similar inefficient double handling.
While exploring the Shopify Programmer documentation, the Admin GraphQL API revealed a user-friendly feature: developers can generate temporary URLs that are capable of receiving files directly from users—eliminating the double handling.
"Developers tin generate temporary URLs that are capable of receiving files directly from users—eliminating the double handling."
This ways the app doesn't need to deal with files and the uploads don't travel every bit far. It'southward a huge win for the app and the user experience. In this commodity, nosotros're going to look at the four steps to create an app that allows a user to upload media files directly to Shopify.
Build apps for Shopify merchants
Whether you lot want to build apps for the Shopify App Store, offer custom app development services, or are looking for ways to abound your user base, the Shopify Partner Plan will fix you up for success. Bring together for free and admission educational resources, developer preview environments, and recurring revenue share opportunities.

Building an upload feature into your app
In this case I'll create a procedure to upload and associate images with collections, just the aforementioned general approach could exist applied to other media types, such as video, or 3D model files.
If you'd prefer to skip straight to the finished code, you can find the completed React project in this GitHub repo, or you tin can view the commits to see each step in detail. Otherwise, let's swoop into a high level overview of each step in the process.
1. Setting up the basics
We tin can go started by using the Shopify App CLI to bootstrap a Node.js app. The Shopify App CLI creates an app in your partner account, generates a skeleton React project (with a Rail or Node.js backend), and starts a server with ngrok.
The app can then exist installed into a evolution shop, and you tin access the app from the store admin. The Shopify App CLI tool tin as well exist used to populate your development store with sample products, which nosotros'll need for creating collections that our uploaded images can be practical to.
"The drop zone component allows merchants to upload files by dragging and dropping files into an area on a page, or activating a push button."
The adjacent step is to listing the stores' collections and add together a Polaris drop zone component for each drove. The driblet zone component allows merchants to upload files past dragging and dropping files into an surface area on a folio, or activating a button.
Depending on how your app may be using file uploads, you lot tin can customize the drop zone element to have only specific file types, or trigger the file dialog from an activeness somewhere else on the page.
When using the drop zone chemical element, ensure that you're post-obit all-time practices and inform merchants when a file can't be uploaded, and provide feedback once the file has been dropped and uploading begins.

2. Preparing the mutations
By default, the app generated by the Shopify App CLI includes Apollo Client, a GraphQL client complete with country management. This will let us to use GraphQL to query store information and alter objects. If you're unfamiliar with GraphQL and how information technology can exist used on Shopify to retrieve and work with data, I recommend you check out our developer documentation on GraphQL.
Nosotros'll need to use two GraphQL mutations: stagedUploadsCreate to generate a temporary URL for our images, and collectionUpdate to actually update the collection'south image property on Shopify's side.
The mutations need to exist wrapped in the gql function which will parse them into query documents.
The useMutation hook returns a function that we can phone call when we're ready to execute a specific mutation.

3. Generate the temporary URL
Once a user drops a file onto the drop zone component, we can request a temporary URL by executing stagedUploadsCreate. The mutation expects an input describing the file. Since we're using a driblet zone component, we take admission to the file object to pull the name, type, and size.
Information technology'southward also worth noting here that this mutation accepts an assortment and can generate multiple URLs at once. For my example, the drop zone has been configured to only allow a single file. The response includes a temporary URL along with parameters used for authentication.

4. Fix a form and commence uploading
Now that we accept the URL and hallmark parameters we can create a new form, append each parameter, and suspend the file itself. The actual upload of the image file is initiated with Fetch.
Assuming we receive an OK response, the upload was successful. The final step is to tell Shopify to utilise this new image by executing collectionUpdate, which expects a collection ID and any properties which have changed (in this instance: the collection image).
To examination that nosotros've set all this up correctly, you can upload an prototype via the app, and when you navigate to the Collections expanse of the admin, you'll meet the image has been applied to a drove. If you're displaying a collection paradigm preview in your app, the modify will be reflected immediately cheers to Apollo Customer's land management.

Use GraphQL to upload files for meliorate app functioning
While information technology'due south not ever possible to send a file directly to Shopify, using this approach where it makes sense can improve the functioning of your app and reduce the distance files travel. The GraphQL Admin API also creates opportunities for apps to manage more types of media like videos and 3D models.
This technique demonstrates how dissimilar features of the Admin GraphQL API can be used in conjunction with Polaris components to implement functionality for your app. In that location'south a wealth of functionality to explore in this API that can be used when developing your apps.
