To handle file uploads in React, you can use the following steps:
Create a file input field: You will need a file input element that lets the user choose a file. You can create this in your component like this:
Handle file selection: The
handleFileChange
function captures the selected file and stores it in the state (file
).Submit the file: In the
handleSubmit
function, we use theFormData
API to append the file to a form data object. This object can then be sent as part of the request body when calling an API endpoint usingfetch
.Handle the response: After the file is uploaded, you can handle the response as needed (e.g., show a success message or handle errors).
You can adjust the endpoint (
/upload-endpoint
) and any additional form fields according to your requirements.
