Usage
With a configuration file (Recommended)
{ "plugins": ["@babel/plugin-proposal-record-and-tuple"] }
Via CLI
$ babel --plugins @babel/plugin-proposal-record-and-tuple script.js
Via Node API
require("@babel/core").transformSync("code", { plugins: [["@babel/plugin-proposal-record-and-tuple"]], });
Options
importPolyfill
boolean
, defaults to false
.
By default this plugin only transforms the proposal syntax, using the Record
and Tuple
globals:
let a = #[1, 2, 3]; // ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ let a = Tuple(1, 2, 3);
You either need to load a polyfill, or you can pass the "importPolyfill": true
option to inject imports to @bloomberg/record-tuple-polyfill
, maintained by the proposal authors:
{ "plugins": [ [ "@babel/plugin-proposal-record-and-tuple", { "importPolyfill": true } ] ] }
let a = #[1, 2, 3]; // ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ ⬇ import { Tuple as _Tuple } from "@bloomberg/record-tuple-polyfill"; let a = _Tuple(1, 2, 3);
Don't forget to add @bloomberg/record-tuple-polyfill
to your dependencies!
polyfillModuleName
string
, defaults to "@bloomberg/record-tuple-polyfill"
.
If you wish to inject imports to a polyfill different from @bloomberg/record-tuple-polyfill
, you can use this option to specify its name.
