Scpos Process

简体中文 | English

The full name of scpoProce is Scpos Process, which is a super high-level Promise-like class for saving the asynchronous problem that has bothered the member of Scpos for about two million years. The inspiration of this super high-level class is the Promise in es6. With the await/async, the convenience it brings can be more violent and stimulating.

The Scpos Process can not only run under Node.js, but also be used in HTML page development. The oldest browser it support is IE5 (ES3).

Import

• NodeJS

  const scpoProce = require('scpo-proce');
  // Or
  import scpoProce from 'scpo-proce';

• HTML

  <!--[if IE]><script src="scpo-proce/es3.js"><![endif]-->
  <script src="scpo-proce/main.js"></script>
  <!--[if IE]></script><![endif]-->

  /// <reference path="scpo-proce/global.d.ts" />
  
  console.log(scpoProce);

Tips

• The behavior of Scpos Process is different from ES6 Promise. ScpoProce.then is Not a microtask like Promise.then. Sometimes, callbacks in ScpoProce.then are more like being executed synchronically.

  setTimeout(() => console.log(1));
  
  new Promise((resolve) => {
    console.log(2);
    resolve();
  }).then(() => {
    console.log(3);
  });
  
  console.log(4);
  
  // Promise.then is a microtask.
  // The output will be "2431".

  import scpoProce from 'scpo-proce';
  
  setTimeout(() => console.log(1));
  
  scpoProce((resolve) => {
    console.log(2);
    resolve();
  }).then(() => {
    console.log(3);
  });
  
  console.log(4);
  
  // Just like sync, not a microtask.
  // The output will be "2341".

Experience After Use

• Pretty convenient.

• Quite magical because of its enigmatic performance that seems even better than ES6 Promise.

• Troubling when my callback throwing the error, because there are too many scpoProce's function in the error tracking log.

  I don't know how the Promise solve this problem. Maybe Promise is achieved by the engine rather than JS codes.

More

• In fact, this project is made by Scpos Web-Request. If you are doing HTML development, The Scpos Web-Request is the better choice, including the delivery of parameter that more eerie, the preset configuration that more comprehensive and so on.

  (But it haven't updated for about two hundred years.)
