rollup-plugin-flow-no-whitespace

library1.0.0jsnpmunverified

A Rollup plugin that removes Flow type annotations from JavaScript files without leaving extra whitespace. Current stable version 1.0.0. Useful for developers using Flow type checking who want to produce clean output after stripping types, avoiding double spaces or blank lines that other plugins may leave. Minimal and focused utility, likely with low release cadence.

Verified usage

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

default

✓ import flowNoWhitespace from 'rollup-plugin-flow-no-whitespace'

✗ const flowNoWhitespace = require('rollup-plugin-flow-no-whitespace')

ESM default import; CommonJS require works but not recommended.

flowNoWhitespace

✓ import flowNoWhitespace from 'rollup-plugin-flow-no-whitespace'

✗ import { flowNoWhitespace } from 'rollup-plugin-flow-no-whitespace'

Named import does not exist; use default import.

plugin usage

✓ export default { plugins: [flowNoWhitespace()] }

✗ export default { plugins: [flowNoWhitespace] }

Must call the default export as a function to instantiate the plugin.

Shows how to import and use the plugin in a Rollup configuration to remove Flow types without whitespace artifacts.

import flowNoWhitespace from 'rollup-plugin-flow-no-whitespace'; export default { input: 'src/index.js', output: { file: 'dist/bundle.js', format: 'cjs' }, plugins: [flowNoWhitespace()] };

Debug

Known issues

gotchaMust use as a function call, not a reference

fix

Use flowNoWhitespace() with parentheses in the plugins array.

affects: >=1.0.0

gotchaOnly removes Flow type annotations, does not handle other transformations

fix

Consider using other plugins for additional transformation needs.

affects: >=1.0.0

deprecatedFlow is not as widely used as TypeScript, may not receive updates

fix

Consider migrating to TypeScript or using a more maintained plugin.

affects: >=1.0.0

gotchaMay not work with Rollup v3 or v4 without adjustments

fix

Check compatibility; plugin was likely built for Rollup v2.

affects: >=1.0.0

breakingWhitespace removal behavior might differ from other type-stripping plugins

fix

Test output thoroughly to ensure whitespace is as expected.

rollup-plugin-flow-no-whitespace is not a plugin

Forgetting to call the exported function

fix

Use flowNoWhitespace() instead of just flowNoWhitespace

Unexpected token (X:Y) in file with Flow type annotations
