# nodejs 使用

* 先创建文件夹
```
yarn init -y
```
* 添加依赖库
```
yarn add @@polkadot/api
yarn add @@polkadot/keyring
yarn add @@polkadot/util-crypto
```

### 添加es2015支持
#### 安装第三方工具:
* 在任意目录下执行，全局安装babel-cli 和 browserify:
```shell script
yarn global add babel-cli browserify

```

* 在工程项目下面执行
```shell script
yarn add babel-preset-es2015
```

* 在项目跟路径下面新建 .babelrc 文件，内容如下
``` 
{
  "presets": [
    "es2015"
  ]
}
```
* 在项目目录下执行
```shell script
babel src -d lib
```
npx babel src/new_index.js -d lib
node ./lib/src/new_index.js

npx babel test/testIcp.js -d lib
node ./lib/test/testIcp.js

npx babel test/testIcpTransfer.js -d lib
node ./lib/test/testIcpTransfer.js

npx babel test/testOffLineTransfer.js -d lib
node ./lib/test/testOffLineTransfer.js

npx babel src/icp_node_server.js -d lib
node ./lib/src/icp_node_server.js
```
执行有可能报错，显示不是内部命令，需要将 yarn global bin 的返回结果添加到path变量中
```
