How to use UUID in applet

Just introduce and use it directly in the mini program like other packages.

Tips:

If the mini program does not support third-party packages, you need to write your own method to export.

This method is available for personal testing. The format of the generated uuid is:

 7b611f1e-6a5f-4501-b658-27295f275066

Create file—_uuid.js

const uuid = function () {
  var s = [];
  var hexDigits = "0123456789abcdef";
  for (var i = 0; i < 36; i++) {
    s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1);
  }
  s[14] = "4"; // bits 12-15 of the time_hi_and_version field to 0010
  s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1); // bits 6-7 of the clock_seq_hi_and_reserved to 01
  s[8] = s[13] = s[18] = s[23] = "-";
 
  var uuid = s.join("");
  return uuid
}

// 需要导出
module.exports = {
    uuid
}

Use:

// 引入
// 使用相对路径引入创建的文件
const util = require('../utils/_uuid.js');

// 使用时直接使用即可
getUUid() {
    const uuid = util.uuid();
    // 可打印值看看
    // `7b611f1e-6a5f-4501-b658-27295f275066`
}
