uploading a uri or should it be converted? - node.js

Question

I am sending image data from my react native application to my node js backend which i want to upload to S3 . I want to know exactly which format i must change the data to in order to upload it to my S3 . Below is the formdata which i am logging in my backend at the moment .
[
'file',
{
uri: 'file:///var/mobile/Containers/Data/Application/CA974BC6-6943-4135-89DE-235BC593A54F/Library/Caches/ExponentExperienceData/%2540lb2020%252Fmy/ImagePicker/D7119C77-60D0-46CC-A194-4F1FDE0D9A3D.jpg',
type: 'image/jpeg',
name: 'hi.jpg'
}
]
My backend has this code below also . Would making the above code equal file work ? if not , suggestions will be appreciated .
const params = {
Bucket:"myarrowbucket", // bucket you want to upload to
Key: "filename"+".png",
Body: file,
ContentType:'image/png',
ACL: "public-read",
};
I have tried uploading and the image doesnt open correctly on S3 or gives me Error: Unsupported body payload object
Updated code - - no path found error
app.post("/upload", async (req, res) => {
const uri = (req.body._parts[0][1].uri)
const file = uri.substring(7);
const fileStream = fs.createReadStream(file);
const params = {
Bucket:"myarrowbucket", // bucket you want to upload to
Key: "filename"+".png",
Body: fileStream,
ContentType:'image/png',
ACL: "public-read",
};
const data = await client.upload(params).promise();
return data.Location; // returns the url location
});

You need to provide a stream to the S3 client.
app.post("/upload", fileUpload(), async (req, res) => {
const uri = (req.body._parts[0][1].uri)
const file = uri.substring(7);
const params = {
Bucket:"myarrowbucket", // bucket you want to upload to
Key: "filename"+".png",
Body: Buffer.from(req.files[0].data, 'binary'), <-- PROVIDE DATA FROM FORM-DATA
ACL: "public-read",
};
const data = await client.upload(params).promise();
return data.Location; // returns the url location
});
You can use a library like form-data to handle the form data conversion.
