Tell you the story about how every babel plugin transform your file inside a blackbox

## Installation

```bash
npm i babel-time-travel -g
```

## Usage

`babel-time-travel` will register a global command named `btt` after a global installation

To use it, simply add your own command after `btt`

> Format: btt [options] -- [your-command]

```bash
btt -- npm run build
btt -- babel src --out-dir lib
btt -- ... # any other command
```

With options

- --filter

  ```bash
  btt --filter axios/lib -- npm run build
  ```

  If babel-time-travel is slow running in your project, you can limit it to only run on certain files by using `--filter` option

Note

- Blackboxed `babel` should run in the same process with your command
- Don't cache any babel transformation result( like babel-loader caching )
- Options like `--filter` should placed before `--`

## Thanks

Highly inspired by [babel/babel-time-travel](https://github.com/babel/babel-time-travel) which supports time travel in browser

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
