js-transpiler

library0.0.5jsnpmunverified

A simple Gulp-based automation script for transpiling ES6 JavaScript to ES5 using Babel, with optional linting via ESLint (airbnb-base config). Copies JS files from source to destination, transpiles files that have an `/* eslint-env es6 */` header. Version 0.0.5, last release 2017. No longer actively maintained. Key differentiators: minimal configuration, RequireJS AMD module support, and file-level ES6 detection. Alternatives: direct use of Babel CLI or Webpack.

Install & Compatibility

Code

Verified usage

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

default

✓ const transpiler = require('js-transpiler');

✗ import transpiler from 'js-transpiler';

CommonJS only; no ESM support.

run

✓ const { run } = require('js-transpiler');

Also available as default.run or as named export.

default

✓ import * as transpiler from 'js-transpiler'; transpiler.run(...)

✗ import transpiler from 'js-transpiler';

Default import does not work; use namespace import in TypeScript.

Basic example: copies all JS files from src to dist, transpiling those with /* eslint-env es6 */ header using Babel presets 'env', no linting.

const transpiler = require('js-transpiler'); transpiler.run({ path: { src: './src/**/*.js', dest: './dist' }, useBabel: true, babelrc: { presets: ['env'] }, useLint: false }); // Then run: gulp

Debug

Known issues

deprecatedPackage unmaintained since 2017. Not compatible with modern Babel (>=7) or ESLint (>=6).

fix

Use Babel CLI directly or update to a maintained alternative.

affects: >=0.0.0

gotchaOnly transpiles files with `/* eslint-env es6 */` comment (first line). Other files are copied as-is.

fix

Ensure all ES6 files start with the magic comment, or set `es6Pattern` option to a RegExp that matches.

affects: >=0.0.0

breakingRequires Node >=7, but not tested on Node 10+. May fail due to deprecated Babel 6 APIs.

fix

Upgrade package or use Node 8/9 LTS.

affects: >=0.0.0

gotchaBabel presets and plugins must be installed globally or locally; no automatic installation.

fix

Run `npm install babel-preset-env` (or desired preset) before use.

affects: >=0.0.0

Errors

Common errors & fixes

Error: Cannot find module 'babel-preset-env'

Missing Babel preset dependency.

fix

Run `npm install --save-dev babel-preset-env`.

TypeError: gulp.src(...).pipe is not a function

Gulp v4 breaking change (stream-based instead of callback).

fix

Use Gulp v3 (`npm install gulp@^3.9.1`) or switch to another tool.

Error: ESLint configuration is invalid

Outdated eslint-config-airbnb-base version or missing plugins.

fix

Install compatible eslint and plugins: `npm install eslint@^4.0.0 eslint-config-airbnb-base@^12.0.0`.
