Meteor Babel Helpers

0.0.3 verified Sat Apr 25 auth: no javascript maintenance

This package provides runtime helper functions used by meteor-babel to transpile JavaScript and TypeScript code within the Meteor framework. Version 0.0.3 is current and tied to Meteor's Babel integration. The package is a fork/subset of @babel/runtime helpers and is published automatically as part of the Meteor Babel toolchain. It is not intended for standalone use; it ships as a dependency of meteor-babel and is bundled into Meteor apps. There have been no updates since 2021, though Babel upstream has released newer versions. Key differentiator: it is the exact set of helpers used by Meteor's build system.

Common errors

error Cannot find module 'meteor-babel-helpers' ↓

cause Manually installing the npm package does not make it work; it must be installed via Meteor's package system.

fix

Remove manual installation. Ensure you are in a Meteor project and run 'meteor update' to get the correct helper package.

error Missing helper: "extends" ↓

cause The package is not present or not properly linked in the Meteor app.

fix

Run 'meteor npm install --save meteor-babel-helpers' (if using npm) but prefer 'meteor add meteor-babel-helpers' if available. Typically Meteor adds it automatically.

Warnings

gotcha This package is not for direct use; it's a runtime dependency of meteor-babel. Importing or relying on it explicitly is not supported and may break in future Meteor versions. ↓

fix Do not install or import this package manually. Let Meteor's build system manage it.

deprecated No updates since 2021; Babel upstream has newer helper versions. Meteor may update this package eventually. ↓

fix Wait for a newer Meteor release that updates this package, or use Meteor 2.x which may pin helpers.

Install

npm install meteor-babel-helpers

yarn add meteor-babel-helpers

pnpm add meteor-babel-helpers

Imports

extends
```
import 'meteor/meteor-babel-helpers'; const x = extends();
```
Helpers are auto-injected by Meteor; manual import is unnecessary and rarely used.
objectSpread
```
import 'meteor/meteor-babel-helpers'; const obj = objectSpread({}, {a:1});
```
Not intended for direct import; included here for documentation completeness.

typeof

import 'meteor/meteor-babel-helpers'; const type = typeof('x');

Replacement for typeof operator; primarily used internally.

Quickstart

Demonstrates that this package is not user-facing, only a runtime dependency.

// This package is not meant to be used directly.
// It is automatically installed by meteor-babel when needed.
// In a Meteor app, you don't need to install or import it manually.

// If you must verify it's present:
import 'meteor/meteor-babel-helpers';
// The helpers are then available globally (e.g., __extends, __assign, etc.).

// Example: using a helper (auto-injected by Babel)
class Child extends Parent {} // transpiled to use _inherits

// To check the version number:
const pkg = require('meteor-babel-helpers/package.json');
console.log(pkg.version); // 0.0.3
