Uploading Files to AWS S3 in React with @aws-sdk/client-s3: Seeking a Clear Example

Other Questions NPM
1

I’m facing challenges uploading files to AWS S3 in my React application.

I tried using packages like react-s3 and react-aws-s3 but encountered errors with my implementation. I then discovered the @aws-sdk/client-s3 library; however, I have not come across a detailed configuration guide. Below is a revised code snippet demonstrating a possible approach to file uploads using this package:

import { S3Client, PutObjectCommand } from '@aws-sdk/client-s3';

const s3Options = {
  bucket: 'MyBucketName',
  region: 'us-east-1',
  credentials: {
    accessKeyId: 'YOUR_KEY',
    secretAccessKey: 'YOUR_SECRET'
  }
};

export const uploadToS3 = async (file) => {
  const client = new S3Client(s3Options);
  const command = new PutObjectCommand({
    Bucket: s3Options.bucket,
    Key: file.name,
    Body: file
  });
  try {
    const response = await client.send(command);
    return response;
  } catch (error) {
    console.error('Upload error:', error);
    throw error;
  }
};

const handleFileUpload = async (fileData) => {
  try {
    const result = await uploadToS3(fileData);
    console.log('Upload successful:', result);
    return result;
  } catch (err) {
    console.error('Error during upload:', err);
  }
};

Any feedback or improved configurations would be greatly appreciated.

hey, i solved my s3 upload isues by checking my region & credntials. retrying on netwrk errrs made a huge difference. double-check your config! hope this helps.

hey, check if your file meta (like content type) is added, might be causing issues; also some creds might be off. i had similar probs and adding extra headers solved it for me, hope it helps!

I have faced similar scenarios and noticed device-specific issues can also result from subtle configuration oversights. While your code seems to capture the primary logic, one improvement I made was including explicit metadata such as ContentType to ensure file properties are correctly interpreted by S3. Additionally, double-checking bucket policies helped me bypass permission pitfalls that are not immediately obvious in the SDK setup. Examining detailed SDK logs further assisted in isolating any discrepancies between expected and actual request parameters. Testing with postman or CLI can also validate if the problem is within the configuration or elsewhere in your environment.

I encountered similar challenges when integrating AWS S3 in my React project. Indeed, it is crucial to verify that your bucket policies and CORS configurations are set appropriately to allow the desired operations. I found that adding explicit metadata, like ContentType, helped S3 correctly interpret my uploads. In my case, refocusing on precise error log details allowed me to isolate permissions issues that were not initially evident. The debugging process reinforced the importance of confirming each step of the configuration to ensure all S3 operations can be performed without oversight.
