Uploading Files to S3 Bucket usign deno-s3-lite-client
Hello, I have been trying to make a file upload controller with deno's s3 lite client but I am facing an issue with uploading the content type of my file. In their documentation, i can read that the way to use the putObject() fucntion is like this:
Deno.test({
name: "putObject() can stream a large file upload",
fn: async () => {
// First generate a 32MiB file in memory, 1 MiB at a time, as a stream
const dataStream = ReadableStream.from(async function* () {
for (let i = 0; i < 32; i++) {
yield new Uint8Array(1024 * 1024).fill(i % 256); // Yield 1MB of data
}
}());
const key = "test-32m.dat";
const metadata = { "Content-Type": "test/streaming", "x-amz-meta-custom-header": "This is a custom value!" };
const response = await client.putObject(key, dataStream, { partSize: 5 * 1024 * 1024, metadata });
assertEquals(response.etag, "ca6d977b6e7dc87ab5c5892e124c7277-7");
const stat = await client.statObject(key);
assertEquals(stat.metadata, metadata);
},
});
And in my code I have it like this:
try {
// Read the file as an ArrayBuffer
const buffer = await fileData.arrayBuffer();
// Convert ArrayBuffer to Uint8Array
const fileArrayBuffer = new Uint8Array(buffer);
("Uploading file to S3 with filePath:", filePath);
// Use contentType option to set the Content-Type header directly
const metadata = {
"Content-Type": fileData.type,
};
// Upload the file using the S3 client
await s3Client.putObject(filePath, fileArrayBuffer, { metadata});
console.log("Upload successful");
// Verify the uploaded file's metadata
const stat = await s3Client.statObject(filePath);
console.log("Uploaded file metadata:", stat.metadata);
return filePath;
Can you tell where the problem is from here?4 replies
