TS项目中经常会用到各种第三方JS库，如base64，md5，xxtea，axios，liquidfun等
这里以axios（一个基于 promise 的 HTTP 库）为例，关于axios，请参考：
https://github.com/axios/axios
1导入JS文件
将JS文件拖拽到编辑器的 资源管理器 面板中目标目录下
2引入JS模块
代码引入
import或者require：
import axios from “./net/axios.js”;
import axios = require("./net/axios.js");
import * as axios from “./net/axios.js”;
const axios = require("./net/axios.js");
上面四种方式均可以引入目标模块
关于其中的区别：
帖子里讲述很详细
Q1: import … = require(…) versus const … = require(…)
At runtime (or once the code is compiled), there is no difference between the two syntaxes, the first one is converted to the second one.
With import:
import x = require(‘x’)
This syntax is specific to TypeScript. The constant x is of type given by some typing defined in the imported package or in a package @types/x.
With const:
const x = require(‘x’)
This is a valid syntax in JavaScript and of course in TypeScript. In TypeScript, the constant x is of type any.
Q2: import … from … versus import … = require(…)
How about difference between import x from ‘x’ and import x = require(‘x’)
The syntax import … from … is from the ES6 standard. I suggest to read this introduction to ES6 modules and how to import and export them.
But, in short, the syntax import x from ‘x’ is equivalent to:
import x = require(‘x’).default
(Notice the .default member.)
How to convert import … = require(…) to the ES6 syntax
The ES6 standard states that all exported members can be imported into a single “namespace object module”.
Then the closest standard syntax of import x = require(‘x’) is:
import * as x from ‘x’
This syntax currently works well with the TypeScript transpilation because the code is converted to a const … = require(…).
However: This syntax should be used only in the context defined by the standard. Because, when your code will use a native version of ES6 modules, you won’t be able to import a function or a class that way.
关于require参数：
1.相对或者绝对路径
①路径中包含后缀名，直接根据路径去查找对应文件
②路径中不包含后缀名，则根据路径依次查找后缀为.js/.json/.node的文件。
如果都找不到，就会在路径下查找该名称的目录
2.模块名
①核心模块
②非核心模块
具体的不再赘述，搜索引擎才是最好的老师
编辑器引入
在编辑器中选中脚本文件，面板右侧勾选：导入为插件
ps:在导入JS文件时，编辑器会提示是否设置为插件，可直接选择是
这样Creator 会脚本中的变量和方法放置在全局命名空间
为了不让vs code报错， 需要在代码中添加声明：
declare const axios: any;
当然不添加声明也可以正常运行
只是vs code会提示错误
3使用库文件
成功引入后，就可以调用其方法了
axios.get(url, {
responseType: “arraybuffer”,
})
.then((response) => {
console.log(response);
})
.catch((error) => {
console.log(error);
});
