require
Introduces the module. Returns the interface exposed by the module via module.exports or exports.
If you need to introduce a module from another subpackage, you can configure the callback function to fetch the module asynchronously. If the asynchronous fetch fails, the error callback function will be triggered.

Note
path
string
yes
You need to introduce the relative path of the module file relative to the current file, or the npm module name, or npm modules path. Absolute path is not supported
You need to introduce a relative path to the module file relative to the current file, or the npm module name, or the npm module path. Absolute paths are not supported by default, you can customise the path mapping by configuring resolveAlias.
callback
function
no
Asynchronous loading success callback function, the callback function parameters for the successful loading of the module
Asynchronous loading success callback function, the callback function parameter is the successfully loaded module.
error
function
no
Asynchronous load failure callback function, the parameters of this callback function are the error message and module name
Asynchronous load failure callback function, the parameters of this callback function are error message and module name.
require.async Chained calls
It can be used by chaining calls.
require
    .async('path/to/mod')
    .then((mod) => {
        console.log(mod)
    })
    .catch(({ errMsg, mod }) => {
        console.error(`path: ${mod}, ${errMsg}`)
    })
Sample Code
Calls within the same package
// common.js
function sayHello(name) {
  console.log(`Hello ${name} !`)
}
function sayGoodbye(name) {
  console.log(`Goodbye ${name} !`)
}


module.exports.sayHello = sayHello
exports.sayGoodbye = sayGoodbye
var common = require('common.js')
Page({
  helloMINA: function() {
    common.sayHello('MINA')
  },
  goodbyeMINA: function() {
    common.sayGoodbye('MINA')
  }
})
Asynchronous Calls Across Subpackages
// subpackage/common.js Subcontracting common files
export const sayHello = () => console.log("hello")
// pages/index.js main package page
let common;
require('../../subpackage/common.js', (mod) => {
    common = mod
}, ({ errMsg, mod }) => {
    console.error(`path: ${mod}, ${errMsg}`)
})
