I was trying to download a file from a bucket on Amazon S3. I was wondering if I can write a javascript to download such a file from a bucket. I was googling it, but couldn't find any resources that can help me do that.
Some steps in mind are: authenticate Amazon S3, then by providing bucket name, and file key , download or read the file so that I can be able to display the data in the file.
Maybe you can use AWS Node. As, I can not store my s3 auth keys on client side, I used my server-side scripts to generate a pre-signed url and send it back to client like:. Was getting url is too long My solution was to include a hidden anchor tag, and trigger the click to that tag on ajax success. You can't use the anchor tag right off the bat unless you don't care about handling errors. S3 will respond with an XML error file if something goes wrong, so the browser will automatically display that XML response.
On success in that ajax call is when you know you're clear to try and download the file. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

I am using the below code. Any suggestions to make it work? What about if AngularJS? Instead of that it gives the option to download. Thanks in advance. Hi, I really need your help. I am using Vue.

Whet am i dong wrong? Thank you very much. You are a life saver! Hi Anders Poulsen, could you please help me , I am trying to open the file in new tab of the browser for the download file functionality. My web API is sending the base64 string and when I am calling the web api , I am getting the following error: unexpected token in during parsing the Json. Thanks man. It took me 10 minutes to make my file download through Ajax work with Chrome and completely fruitless to make it work with IE.
Thanks to you it finally worked. Could you please help in this…. I am using this but I have a question. Is there any way to receive a callback once the download is finished? As far as I have tested this, link. For this to work in ie 11 and Edge, there need to be and file extension to this line: window. Thanks for writing such a nice post. In my case, the server streams the file.
From my understanding when creating a blob, we wait for the entire file to be read into the blob and then create a URL from the blob. Is there a way where i can start the download as soon as receive the response stream and not wait for the entire file? I am not able to download the file with its file name in secondry window. Is there any approach to solve this in angular js? Facing this issue on both Chrome and firrefox. Excellent article. Very difficult to find clear examples of fetching PDF files.
