SDKs and S3

You've escaped writing code for a while - this one will have you write a lot of code and might take a bit of time, that's okay!

Bun provides integration with AWS S3 with a blazingly fast S3 API.

1. Update the ApiConfig type in config.ts
   1. Import s3 and the S3Client type from bun. Bun.s3 is a default client that uses the environment variables for credentials.
   2. Add an s3Client field to ApiConfig.
   3. Assign the autogenerated s3 client to the s3Client field.
2. Update the S3_BUCKET, S3_REGION, AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY variables in your .env file. If you followed the setup earlier, your keys should be available in ~/.aws/credentials.
3. Complete the (currently empty) handlerUploadVideo handler to store video files in S3. Images will stay on the local file system for now. I recommend using the image upload handler as a reference.
   1. Set an upload limit of 1 GB (1 << 30 bytes). Check our handlerUploadThumbnail as a reference.
   2. Extract the videoId from the URL path parameters
   3. Authenticate the user to get a userID
   4. Get the video metadata from the database, if the user is not the video owner, throw a UserForbiddenError error.
   5. Parse the uploaded video file from the form data
      • Use formData.get() with the key "video" to load the file in memory.
   6. Check that file size does not exceed our upload limit. If it does, throw a BadRequest error.
   7. Validate the uploaded file to ensure it's an MP4 video
      • Use Blob.type and check if the MIME type is "video/mp4"
   8. Save the uploaded file to a temporary file on disk.
      • Use Bun.write to create a temporary file.
      • Remember to remove the temp file when the process finishes.
   9. Put the object into S3 using S3Client.file(). You'll need to provide:
      • The file key. Use the video ID as the key. e.g. <videoId>.mp4
      • The file contents (body). You can use Bun.file() to read the contents of the file in the temporary path.
      • Content type, which is the MIME type of the file.
   10. Update the VideoURL of the video record in the database with the S3 bucket and key. S3 URLs are in the format https://<bucket-name>.s3.<region>.amazonaws.com/<key>. Make sure you use the correct region and bucket name!
   11. Restart your server and test the handler by uploading the boots-video-vertical.mp4 file. Make sure that:
       • The video is correctly uploaded to your S3 bucket.
       • The video_url in your database is updated with the S3 bucket and key (and thus shows up in the web UI)

Run and submit the CLI tests.
