[@alienalien9288]

Hi!, great video, one question tho, after sending the images (sdkv3) and then we get the 'results', is there anyway for me to get the objectUrl for that image, so then i can add it to my UserModel?

[@senduranravikumar3554]

Ithuthaan naa search paneedu irunthan.. thanks naa

[@mohammedraqeeb4392]

Thank you

[@trevorg2069]

Should you also use the package file-type to determine file type based on the magic number or signature and then compare that with the mimetype provided by multer and reject the request if they dont match?

[@anilpoudel5974]

Sir suppose I have AL3 file in my desktop and I need to convert that format and read using third party API how I will upload file in that API and retrieve that file in particular format without the use of any object just normally passing desktop file.

[@milon27]

is it good to use multer, i read that multer store the full file in memory instead of using stream.what do you think?

[@critical-games]

Nice tutorial! But can you explain how to serve these files as public urls to the front end ? If you have front end app where you show 1000 photos to a single visitor, do you have to pay for 1000 requests to AWS? Where is the "next video" you mention in this video? Thank you!

[@ericdelmermillen]

Very helpful video: I'm now able to post to my S3 bucket from postman but am unable to post when calling from my react app. I'm having trouble attaching the files correctly so that they are available on the req.files. Any help would be appreciated.

[@abhijeetshikharvlog1444]

Can u tell how u image crop and upload

[@EricMillen]

This video helped me implement photo uploading from my node app but now I'm stuck on deleting. Any chance you have a tutorial on that?

[@EkUntoldKahaani]

Using the Javascript v3 how i could retrieve link to the image uploaded to s3? I want store the link in mongoDB

[@maheshgowripatnam6340]

Hi All, upload works perfectly but I need the uploaded response back, can any one help me how to return the images response.

[@peterkerr9685]

Hi there, am trying to use Multer and getting an error saying "Unexpected end of form", anyone have any idea why this would happen?

[@Shin-jj3qt]

How to get the location link of the image?

[@venkatsurya4438]

How to delete the s3 bucket upload file ??

[@WaseemAhmad-mf3wh]

Hi Sanjeev, can you please guide me a bit i want to make that file url secure so that only paid user can access the url, how can i do this?

[@SanjeevThiyagarajan]

Look up s3 oresigned urls

[@carlosphilips9879]

so how can you validate two images with two different mimetypes lets say one is and audio and the other is an image

[@darentok8608]

you use if ( file.mimetype.split("/")[0] === "audio" || file.mimetype.split("/")[0] === "video" ) { cb(null, true); } comparing them with or || or you can be more specific and not split it just audio/mpeg or even video/mpeg

[@MOVIE-KIDA]

what if file too small or empty ??

How to upload excel file ?

[@rambideunt]

How about using/hosting it ourself using MinIO? If this video is gold, then the MinIO one would be diamond!

[@SanjeevThiyagarajan]

minio is s3 compatible api, so nothing really changes

[@parikshithshivaprakash5523]

[@tvssaini]

Using memory storage before uploading to S3 is not a good idea. It will not scale very well.

[@alienalien9288]

why not? whats the diference between memory and disk?

[@tvssaini]

@@alienalien9288 Memory Storage = RAM and Disk Storage is equivalent to Hard Disk. Disk storage is slow and costly and Memory Storage is fast but very very costly. When many people try to upload a files at the same time, it can cause your application to run out of memory. Possible solution is to use PreSigned URL to upload files to S3.

[@alienalien9288]

@@tvssaini i read something about, when it goes to memory, then if u send it to s3 its removes the buffer from the memory immideiatly?

[@tvssaini]

@@alienalien9288 Yes that is true. It all depends upon the amount of memory your server has. My original point was it is not ideal solution if your app has thousands or millions of users. Solution works for sure but it will cost you a lot. i.e. not scalable.

[@alienalien9288]

@@tvssaini oh ok, btw ive implemented cloudfront and now have a domain and want to save the url of the image to my mongodb, but results doesnt give the url or imagename, do you know how i can get it?
