Installation

$ npm install --save-dev @babel/plugin-proposal-pipeline-operator

Usage

With a configuration file (Recommended)

{
  "plugins": [["@babel/plugin-proposal-pipeline-operator", { "proposal": "minimal" }]]
}

The Pipeline Proposal is one of three competing implementations. Which implementation the plugin should use is configured with the "proposal" option. This option is required and should be one of:

• "minimal" – Minimal Pipeline
• "smart" - Smart Pipeline - Added in v7.3.0
• "fsharp" - F#-Style Pipeline - Added in v7.5.0

When one of the implementations is accepted, it will become the default and the "proposal" option will no longer be required.

Via CLI

$ babel --plugins @babel/plugin-proposal-pipeline-operator script.js

Via Node API

require("@babel/core").transform("code", {
  plugins: [
    [
      "@babel/plugin-proposal-pipeline-operator",
      {
        "proposal": "minimal"
      }
    ]
  ]
});
