解决在chrome中运行的tensorflow js解决“未捕获（承诺）TypeError：fs.​​writeFile不是函数”的另一种方法

Question

I have been trying to export a variable in the the tensorflow posenet model running in chrome browser in the code snippet below. However reading through discussions , it seems one cannot export a variable using fswritefile in the chrome browser. I was wondering if there is any other possible way to export to json file ? if some one has managed it ?

export function drawKeypoints(keypoints, minConfidence, ctx, scale = 1) {
  for (let i = 0; i < keypoints.length; i++) {
    const keypoint = keypoints[i];

    if (keypoint.score < minConfidence) {
      continue;
    }

    const {y, x} = keypoint.position;
    drawPoint(ctx, y * scale, x * scale, 3, color);
  }
  //console.log(keypoints);
 let test = JSON.stringify(keypoints);
 fs.writeFile('extract.json', test, (err) => {  
  if (err) throw err;
  console.log('Data written to file');
});

Answer 1

fs is a nodejs specific module. It can't be used in the browser. Blob saving to a file is the standard way of writing to a file in the browser environment

Answer 2

Fs is Node.js/commonJS module and you need an equivalent browser-based ES6 supported module. In my personal experience,I had to use Fs wrapper in browser like browserfs , browserify-fs or fs-es6 as a workaround.
