使用 node.js 在哈巴狗（玉）上显示来自编码 base64 的图像

Question

How to decode this data (I'm not sure if what type is this) and display the image. I'm using pug as template engine.

Here is the data that I need to display as an image:

/9j/4AAQSkZJRgABAQEAYABgAAD/4QBaRXhpZgAATU0AKgAAAAgABQ...and so on

I tried this code in my node.js but it doesn't work

var img = Buffer.from(image).toString('base64');

The variable image is from this response:

While this code is for passing data to.pug file

res.render('getsurveyemployeeimg', {
   surveyId: results[0].surveyId,
   empNo: results[0].empNo,
   empName: employee.result.fullnameEn,
   empImg: img,
   date: created,
   answers: results
});

.pug file

img(src="data:image/jpg;base64,#{empImg}")

I always keep on getting broken image icon as an output

Code is for passing data to.pug file:

res.render('getsurveyemployeeimg', {
   surveyId: results[0].surveyId,
   empNo: results[0].empNo,
   empName: employee.result.fullnameEn,
   empImg: image,
   date: created,
   answers: results
});

.pug file should look like this:

img(src="data:image/jpg;base64," + empImg)

After that, everything should work if empImg actually contains a base64 image.
