Downloading pdf or any other documents is very common in day-to-day web applications. We often see buttons like Download, Generate Invoice, etc buttons in web applications that makes calls to a GET endpoint which does some computations and downloads pdf or any other document file.
While working on one of the projects I added an endpoint i.e. /generate-invoice(GET) in a Phoenix application. Its job was to do some tabular computation and generate a PDF. I added a link tag to call the endpoint something like this
<%= link "Invoice", to: "/generate-invoice", class: "button" %>
As expected it was working fine but later I noticed a weird behavior. After clicking the Invoice button when I tried to click other buttons or any action that involved javascript, it wasn't working. I thought there was some bug with my endpoint or other code I tried to fix it but things weren't working for me.
When we try to access a GET endpoint that downloads, the browser navigates away from the current page. It doesn‘t know the target will download something, and will therefore shut down the javascript of the current page. Till then I wasn't aware of the download attribute on the link tag. Adding the download attribute on the above link tag helped me in fixing the problem.
<%= link "Invoice", to: "/generate-invoice", class: "button", download: 'invoice.pdf` %>
