How to convert binary image data to URI for same image in nodejs?
0
I am using one API to get a profile photo of a user. This api gets me the binary data for a profile photo.
I need to be able to use this profile photo in form of a https://en.wikipedia.org/wiki/Data_URI_scheme
example:- json that will render an image where value of url should be URI.

"type": "AdaptiveCard",
"version": "1.0",
"body": [
{
"type": "Image",

You need to use btoa().
const imagData = 'data:image/png;base64,' + btoa('your-binary-data');
The 'btoa-atob' module does not export a programmatic interface, it only provides command line utilities.
If you need to convert to Base64 you could do so using Buffer:
Buffer.from('your-binary-data').toString('base64')

btoa() isn't defined in nodejs. I think it works in plain javascript.

Nov 13 at 20:37
I used following code to get URI using buffer. Body = raw image byte received from rest API. var buf = Buffer.from(body); var base64Data = buf.toString('base64') const imageURI = 'data:image/png;base64,' + base64Data; Then i used online convertor to test my URI & it didn't converted to image. I'm guessing this base64 isn't correct. I used another online converter which gives base64 using direct image upload & that works. site24x7.com/tools/datauri-to-image.html any thoughts ?

which version of node are you using? is it possible for you to test the raw binary if that is valid?

Hi Narendra I'm on node v10.10.0 I am using following API to get binary. I confirmed it used REST client Postman & it does gives me image back. In nodejs app it shows me raw bytes which I pass it to Buffer. developer.microsoft.com/en-us/graph/docs/api-reference/beta/api/…
