# babel-udf-helpers
[](https://badge.fury.io/js/babel-udf-helpers)
[](https://circleci.com/gh/yukihirop/babel-udf-helpers)
A tool to create user-defined helpers that can be used in your babel plugin.
The usability is like that of @babel/helpers.
## 📦 Installation
```js
npm install --save-dev babel-udf-helpers
```
## ❤️ Support Version
- node.js (>=10.15)
- typescript target (ES2018)
## 📖 Usage
Use in your babel plugin as follows.
It works the same as babel-helpers addHelper, so you can use it anywhere in your visitor.
```js
import { useDangerousUDFHelpers } from 'babel-udf-helpers';
import helpers from './helpers';
export default function({types: t}){
pre(){
useDangerousUDFHelpers(this, { helpers });
},
visitor: {
Program(path){
this.addUDFHelper("programHelper")
},
ImportDeclaration(path) {
this.addUDFHelper("importHelper")
}
}
}
```
`helpers.js` looks like the following.
```js
import { helper } from 'babel-udf-helpers';
const helpers = Object.create(null);
export default helpers;
helpers.programHelper = helper`
export default function _programHelper(){
return "programHelper";
};
`
helpers.importHelper = helper`
export default function _importHelper(){
return "importHelper";
};
`
```
