    Thanks so much. Finally understand how to use multer because of you. I like how you explain how to make request from normal front-end HTML, React as well as Postman. Everything was easy to understand and the most important thing is that all of that was step-wise and in one video. Keep making videos like this one.

    Hey man, thanks for the video! Really helpful.
    Say, how do you handle errors in multer, specifically in the diskStorage engine? you pass a null to the cb function, which is where the error should be, but it's not explained exactly why that is, or what to do with it. I checked the multer documentation also, it's not explained (crappy documentation is a terrible, terrible thing).

      @the_full_stack_junkie  7 дней назад

      @@Pets-px3lu would probably do it in 2 steps uploading the images and receive back the urls. Then when linking images to another entity you can save the details with the entity as part 2.
      Between these 2 steps you can do many things with naming and ordering, so it really depends on the use case. But its always possible to make an endpoint only for uploading images. And respond with the url, filename etc and then do the ordering of the images in the 2 step.

    This is really good I used multer in one of my project to upload image on server and deployed on heroku it was initially working..but after few hours when I reopened it image was gone...rest all the data where coming from backend...I don't know is the problem with multer or heroku??

    • @the_full_stack_junkie
      @the_full_stack_junkie  3 года назад +1

      Hey man so basically heroku dont allow you to store images for a long period of time once the dyno goes to sleep it clears any additional files stored. Would recoomend using an AWS S3 bucket to store your images in and then store the url to that bucket containing the assets in your database. You wil still be able to use multer the same as in the video you wil just need to hook up jou storage to work with AWS and there are many videos and tuts online showing how to do this. Hope this helps

      Yes this is possible you would then just need to create for example different multer instances.

      Initially I just think the folder destination could only be set in advance for every multer instance, so I was just thinking of sending the files to the assigned destination first, then just move them to the "new" dedicated folder later on in a callback at the Express route, but I don't know if that would be resource efficient.
