I had an image file on my filesystem and I wanted to put it inside an HTML page using the data-uri format so I could embed it into the page itself.
Here’s how I did it:
const imageData = fs.readFileSync(fileLocation, 'binary')
const src = `data:${contentType};base64,${Buffer.from(
imageData,
'binary'
).toString('base64')}`
In my case I just download that image from the Internet, so I retrieved contentType
from the response headers:
const contentType = response.headers['content-type']
In the end I was able to use src
inside an img tag like this: <img src={src} />
