Error while using image-watermark in node.js

Question

I am using image-watermark for adding watermark to a file on server side node.js and it is producing an error.

I tried installing modules image-watermark, imagemagick, and other dependencies. At first, I faced a problem similar to this. But, this problem was resolved by installing ImageMagick into my system and now that is resolved from this answer.

Now, I am getting an error in the following code:

const watermark = require('image-watermark');
const imagePath = path.resolve(__dirname,'./relative/path/to/image');
watermark.embedWatermarkWithCb(imagePath, { 'text': 'sample watermark' }, 
function (err) {
    if (!err)
      console.log('Succefully embeded watermark');
    else {
      //I am getting error here.
      console.log(err);
    }
});

The image file should be exported with a watermark. But, instead I am getting this error:

{ Error: Command failed:
    at ChildProcess.<anonymous>(...\node_modules\imagemagick\imagemagick.js:88:15)
    at emitTwo (events.js:131:20)
    at ChildProcess.emit (events.js:214:7)
    at maybeClose (internal/child_process.js:925:16)
    at Process.ChildProcess._handle.onexit 
(internal/child_process.js:209:5) timedOut: false, killed: false, code: 1, 
signal: null }

I used this answer to get to the root cause of the error. Without that I got Error: spawn ENOENT error only.

just for discard, try the following: - sudo node your_app.js — ene_salinas, May 29 '19 at 05:20

I prepare a basic example for you:

download the code here

Pre-requisite:

install imagemagick in SO
install ghostscript in SO (for pdf files)

Ex. for mac:

brew install imagemagick
brew install ghostscript (for pdf files)

The steps are the following:

- You must enter the folder ./stackoverflow/56353310/

- npm install

- node index.js

The output must be something like that:

any question please let me know.

This works fine if I am using it on a different module. Also, this doesn't work for **pdf** – Sushant Paudel May 30 '19 at 10:29
@SushantPaudel I edited the answer, basically you need to install ghostscript for pdf files, do you need anything for close this question? let me know. – ene_salinas May 30 '19 at 19:31
