# mine-jsjs
一个ts实现的js解释器
## 安装
```bash
$ npm install mine-jsjs
```
## 使用方法
```javascript
import { run } from 'mine-jsjs'
run(code, options)
```
直接跑代码
```javascript
import { run } from 'mine-jsjs'
run(`console.log("hello world!")`)
// hello world!
```
直接跑ast节点
```javascript
import { run } from 'mine-jsjs'
run(
{
"type": "Program",
"start": 0,
"end": 26,
"body": [
{
"type": "ExpressionStatement",
"start": 0,
"end": 26,
"expression": {
"type": "CallExpression",
"start": 0,
"end": 26,
"callee": {
"type": "MemberExpression",
"start": 0,
"end": 11,
"object": {
"type": "Identifier",
"start": 0,
"end": 7,
"name": "console"
},
"property": {
"type": "Identifier",
"start": 8,
"end": 11,
"name": "log"
},
"computed": false
},
"arguments": [
{
"type": "Literal",
"start": 12,
"end": 25,
"value": "hello world!",
"raw": "'hello world!'"
}
]
}
}
],
"sourceType": "module"
}
)
// hello world!
```
参数选项
`options.injectObj`: 通过这个对象可以将外部变量注入到内部代码
例子:
```javascript
import { run } from 'mine-jsjs'
const str = 'hello'
run(`console.log(hello + ' world')`, { hello: str })
// hello world
```
`options.module`: 按照module的方式运行code，运行后会返回内部代码export的变量
例子：
```javascript
import { run } from 'mine-jsjs'
run(`
exports.hello = 'hello'
`)
// { hello: 'hello' }
```
