webpack-remove-code-blocks

library0.10.1jsnpmunverified

A webpack loader plugin that removes blocks of code marked with special comment labels (e.g., `/* devblock:start */.../* devblock:end */`) from files processed by webpack. Current stable version 0.10.1 supports webpack >=3.0.0 and Node.js >=18. It allows multiple named block definitions, optional replacement text, and modes to skip removal based on webpack's `mode` option. Differentiates from alternatives by supporting custom labels, prefixes, and suffixes, and being actively maintained.

Verified usage

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

default export (plugin instance) loader function

✓ module.exports = { module: { rules: [ { test: /\.js$/, use: 'webpack-remove-code-blocks' } ] } }

✗ Use via require('webpack-remove-code-blocks') as a constructor or class.

The package exports a loader function directly, not a class or object. Use it as a string or object in webpack rules.

loader path in webpack config

✓ loader: 'webpack-remove-code-blocks'

✗ loader: require.resolve('webpack-remove-code-blocks')

The loader name is a string; webpack resolves it from node_modules.

options object for custom blocks

✓ options: { blocks: ['debug', { start: 'devblock_start', end: 'devblock_end', prefix: '/*', suffix: '*/' }] }

✗ Options passed as a separate argument or via plugin syntax.

Options are passed as an object under the `options` key in the rule's use array.

Shows basic webpack configuration to remove code blocks labeled `devblock` from .js files, with input and expected output.

// webpack.config.js module.exports = { module: { rules: [ { test: /\.js$/, exclude: /node_modules/, use: [ { loader: 'webpack-remove-code-blocks', options: { blocks: ['devblock', 'debug'] } } ] } ] } }; // Input file: app.js /* devblock:start */ console.log('remove me'); /* devblock:end */ console.log('keep me'); // Output: 'keep me' block only

Debug

Known issues

breakingVersion 0.9.0 drops support for Node.js 16 and contains massive refactoring; may break older configs.

fix

Upgrade to v0.10.1 or ensure Node.js >=18. Check block definitions as option format may have changed.

affects: >=0.9.0 <0.10.0

breakingVersion 0.9.0 changes versioning and is described as a 'candidate for the initial release'; may introduce incompatibilities with earlier v0.1.x.

fix

Review changelog for breaking changes; update block options if using custom start/end labels.

affects: >=0.9.0 <0.10.0

deprecatedNode.js 16 support dropped in v0.9.0.

fix

Use Node.js >=18 for v0.9.0+.

affects: >=0.9.0

gotchaLoader name is 'webpack-remove-code-blocks' not 'webpack-remove-block' (similar package).

fix

Verify spelling in webpack config; use 'webpack-remove-code-blocks'.

affects: all

gotchaIf no `blocks` option provided, default blocks may not be defined; the loader may process nothing.

fix

Always specify at least one block label (e.g., `blocks: ['devblock']`).

affects: >=0.1.0

Errors

Common errors & fixes

Module not found: Error: Can't resolve 'webpack-remove-code-blocks'

Loader name typo or missing npm install.

fix

Run `npm install --save-dev webpack-remove-code-blocks` and ensure the loader name is exactly 'webpack-remove-code-blocks'.

TypeError: loader is not a function

Using require() result as a constructor or plugin instead of a loader string.

fix

Use loader: 'webpack-remove-code-blocks' in the webpack rule, not as a plugin or function.

No blocks removed from output

Missing `blocks` options or wrong comment syntax.

fix

Add `options: { blocks: ['devblock'] }` to the rule and use correct comment syntax: `/* devblock:start */ ... /* devblock:end */`.

Error: Mode removal not working

Mode option expects array of webpack mode strings; may be misconfigured.

fix

Check docs: mode value should be an array like `['development']` to skip removal in that mode.
