babel-plugin-streamline

library2.0.26jsnpmunverified

Babel plugin that enables compile-time transformation of Streamline.js async syntax (callback-, fiber-, and generator-based) within the Babel ecosystem. This package (version 2.0.26, last stable) allows you to combine Streamline's non-blocking control flow with Babel's transpilation pipeline. Key differentiators: integrates Streamline's _ (callback) / fiber / generator modes as Babel plugins, requires matching Babel major version, and is primarily for legacy projects using Streamline.js. Release cadence is low; mainly maintenance updates.

Verified usage

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

plugin

✓ { plugins: ["streamline"] }

✗ { plugins: ["babel-plugin-streamline"] }

Babel plugin name is 'streamline' not full package name

options

✓ { extra: { streamline: { runtime: 'callbacks' } } }

✗ { plugins: [["streamline", { runtime: 'callbacks' }]] }

Options are passed via extra.streamline, not plugin array args

use with generators

✓ { extra: { streamline: { runtime: 'generators' } }, blacklist: ['regenerator'] }

✗ { extra: { streamline: { runtime: 'generators' } } }

Must blacklist regenerator plugin when using generators runtime

Configures Babel to transform Streamline.js callback-style async code using the callbacks runtime.

// Install: npm install babel-plugin-streamline babel-core // .babelrc { "plugins": ["streamline"], "extra": { "streamline": { "runtime": "callbacks" } } } // Input file (app._js) function delay(ms, callback) { setTimeout(callback, ms); } function test() { console.log('before'); delay(1000, _); console.log('after'); }

Debug

Known issues

breakingbabel-plugin-streamline only works with Babel 5.x and 6.x; not compatible with Babel 7+

fix

Do not use with Babel 7; consider switching to @babel/plugin or alternative async transform.

affects: >=2.0.0

gotchaOptions must be placed under babel's extra object, not as plugin arguments.

fix

Set options via extra.streamline in Babel config.

affects: >=0.0.0

gotchaWhen using 'generators' or 'fibers' runtime, you must blacklist Babel's regenerator plugin to avoid conflicts.

fix

Add 'blacklist': ['regenerator'] to Babel config when runtime is not 'callbacks'.

affects: >=0.0.0

deprecatedPackage is in maintenance mode; no active development; consider migrating away from Streamline.js.

fix

Replace Streamline.js with async/await or other modern async patterns.

affects: >=0.0.0

Errors

Common errors & fixes

ReferenceError: _ is not defined

Missing or incorrect require of streamline runtime (e.g., require('streamline').register())

fix

Add require('streamline').register() at entry point or use runtime option 'callbacks' which auto-includes helpers.

Babel 7: Cannot find module 'babel-plugin-streamline'

babel-plugin-streamline is not compatible with Babel 7; npm install may fail or resolve incorrectly.

fix

Downgrade to Babel 6 or use an alternative async transform (e.g., @babel/plugin-transform-runtime).

TypeError: Cannot read property 'transpile' of undefined

Using plugin array syntax with options instead of extra object.

fix

Move options to extra.streamline in Babel config; do not pass options as second element in plugins array.
