Build a File Upload API to AWS S3 Bucket | .txt, .jpeg, .png, .pdf 

Thank you for this fast and easy tutorial. Used the method you showed to integrate into an app I created.

Thanks Felix, this was a great tutorial and extremely helpful

Thank you for such a straightforward solution! I was able to follow your tutorial easily and upload a file to AWS S3 without any trouble. Thank you for sharing your knowledge! I have one question though. Is it possible to upload a file to a specific folder within a bucket on AWS S3? If so, could you please explain the process of achieving this? I would greatly appreciate your guidance. Keep up the amazing work!

I love the video! Would you ever consider doing a video on how to upload multiple files at once/uploading an entire folder?

Very helpful! Thank you!

The content helped me! Thanks!

Awesome awesome awesome. The AWS UI has changed a bit but this tutorial works perfectly.

OMG THANK U SO MUCH FOR THIS VIDEO! UR A LIFESAVER BRO THANKSSSS!!!

Thanks for the tutorial. API Gatwway has a limit of max 10MB request payloads. Is the technique described in your video also limited to a max 10MB upload?

great tutorial!

A follow up video of using a presigned url using lambda would also be good.

great stuff! Would love to see this with authorization feature

I am getting access denied error. Could you please share the steps to handle the authentication for the upload in postman?

Can I integrate this api with the api created in the previous video on file-upload ? Cos i'm facing some issues with Postman..the error is simply "Internal Server Error"...

Hi, nice tutorial! I am not a front-end man at all but I would be helped a lot to have an overview how I can trigger this API with a file selected in a file-input in HTML.

For those who, as me, were having your files corrupted on upload, don't forget to set a header for your upload file as - "Content-Type", "image/png"

when I do this from postman, it works, but when I embed the javascript snippet from postman and try to integrate the frontend from my html file, I get told that the access to fetch at the gateway from origin 'null' is denied by the CORS policy? how can I fix this?

On production environment doesn’t run, Cors error

Excellent tutorial. Works great from, postman. When I try uploading from React application, I'am able to upload files but jpeg and png file seem corrupted (text files are fine). Any ideas on how this can be resolved?

Hey bro..its working correctly through postman, but I am getting CORS error while using it through React, can you help me out with this, thanks in advance

Is it possible to get a custom response? Once I upload the image, can I get the file URL or something like that?

Awesome and this works. But m trying to integrate this with a front end html code and this is proving to be very difficult

Thank you so much. But could you please make a video on how to use {proxy+} to upload to s3 folders directly? Please?

I am uploading an application/json file. It does get uploaded but is blank. Any ideas on what i may be missing ?

I did every step but the result show me in postman with error MalformedXML The XML you provided was not well-formed or did not validate against our published schema, anyone can help?

I've created a mobile app which consists of forms, these forms store the text data in MongoDB Atlas and the images in AWS S3, the MongoDB Atlas is a serverless service, but I'm needing a middleware to communicate with it. The AWS S3 is also needing a middleware to upload the images. Currently I'm running this middleware servers on my local machine(Local Host), but I need a serverless service for these two node servers to run 24/7, but I want to only pay for the time that I use these. Please help me Guys, I'm a beginner.

any one tried to put file into nested location of the bucket?

that is also work for uploud videos?

The create policy button is no longer there?

This tutorial is very old and AWS has changed a lot of things. I am unable to add curly braces ({ ) in the resource path because it is a drop down in latest AWS UI.

"message": "Missing Authentication Token"

Invalid mapping expression specified: Validation Result: warnings : [], errors : [Invalid mapping expression parameter specified: method.request.path.filename] How do I solve this?

While using PUT, the file that it can accept is image/png and the file size is 3MB, I have tried with even 1B size and I keep getting: MaxMessageLengthExceededYour request was too big.10240
