babel-plugin-transform-vite-meta-hot

library1.0.0jsnpmunverified

A Babel plugin that emulates Vite's import.meta.hot API for non-Vite environments, primarily used in test runners like Jest or Mocha. Version 1.0.0 is the initial stable release (January 2023), with no subsequent updates. It transforms import.meta.hot calls into module.hot equivalents, enabling HMR-like code to run in Node.js. Unlike full Vite presets, this is a focused plugin for HMR simulation only. It ships TypeScript type definitions and is part of the babel-vite suite.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default export

✓ import plugin from 'babel-plugin-transform-vite-meta-hot'

✗ const plugin = require('babel-plugin-transform-vite-meta-hot')

ESM works; CJS require is also supported due to dual package support.

Shows setup, input with import.meta.hot, and transformed output using module.hot.

// Install: npm install --save-dev babel-plugin-transform-vite-meta-hot // In .babelrc or babel.config.js: { "plugins": ["babel-plugin-transform-vite-meta-hot"] } // Source code with Vite HMR: if (import.meta.hot) { import.meta.hot.accept((newModule) => { console.log('HMR update'); }); } // After Babel transform: if (module.hot) { module.hot.accept((newModule) => { console.log('HMR update'); }); } // Use with Jest: add to jest.config.js transformIgnorePatterns or babel config.

Debug

Known issues

gotchaOnly transforms import.meta.hot, not other Vite meta properties like import.meta.env or import.meta.glob.

fix

Use babel-plugin-transform-vite-meta-env or babel-plugin-transform-vite-meta-glob for those respectively.

affects: >=1.0.0

gotchaThe transformation is an approximation; module.hot may not be defined in all environments, causing runtime errors.

fix

Add a conditional check like if (typeof module.hot !== 'undefined') before using the transformed code.

affects: >=1.0.0

deprecatedNo active development; last release 1.0.0 over a year ago. Consider using babel-preset-vite for comprehensive Vite compatibility.

fix

Switch to babel-preset-vite which includes this plugin and others.

affects: >=1.0.0

Errors

Common errors & fixes

SyntaxError: /path/to/file.js: Support for the experimental syntax 'importMeta' isn't currently enabled

Babel parser doesn't recognize import.meta syntax; needs appropriate plugin or preset.

fix

Add '@babel/plugin-syntax-import-meta' or use babel-preset-vite which includes it.
