Fetch and download a PDF file with Axios and Javascript
Posted on October 23, 2021
Here the tip to download a binary file, such as a PDF, ZIP or image file with axios:
// within an async function
const res = await axios({
responseType: 'blob',
url: URL_TO_BINARY_FILE
})
// res.data will contains the binary data of the file
Now, if you want to force the download to the user browser, here the very popular trick:
const url = window.URL.createObjectURL(new Blob([res.data]))
const link = document.createElement('a')
link.href = url
link.setAttribute('download', 'myFile.pdf')
document.body.appendChild(link)
link.click()
