babel-plugin-transform-dirname-filename

library1.1.0jsnpmunverified

Babel plugin (v1.1.0) that rewrites __dirname and __filename to static values at compile time, preserving original source file paths in bundled output. Stable, no recent updates since 2022. Different from other solutions (e.g., webpack.DefinePlugin) as it works specifically with Babel for transpilation, ensuring that after bundling, __dirname and __filename reflect the source file location rather than the output directory. Suitable for Node.js packages distributed as compiled code.

default

✓ // In .babelrc plugins array: 'transform-dirname-filename'

Used as a Babel plugin, not imported in code. Install as devDependency and add to Babel config.

Shows installation, Babel config, and expected behavior: __dirname/__filename are rewritten to source file paths.

// Install: npm install --save-dev babel-plugin-transform-dirname-filename // .babelrc { "plugins": ["transform-dirname-filename"] } // src/index.js console.log(__dirname); console.log(__filename); // Run: npx babel src --out-dir build // Output build/index.js will contain static paths from source

Debug

Known issues

gotchaOnly works with Babel 6.x. For Babel 7+, use @babel/plugin-transform-dirname-filename (fork) or consider alternatives like babel-plugin-transform-dirname-filename (compatible with Babel 7 via wrapper).

fix

For Babel 7, install @babel/plugin-transform-dirname-filename or use the community fork.

affects: >=1.0.0

breakingPlugin rewrites __dirname and __filename at compile time to absolute paths of the source files. This may leak filesystem structure and break if the output is moved or used in a different environment.

fix

Use relative paths or ensure the built output is consumed in an environment with the same source structure.

affects: all

gotchaDoes not transform require() calls. Only __dirname and __filename are replaced.

fix

If you need to transform require paths, combine with other plugins like babel-plugin-module-resolver.

Errors

Common errors & fixes

Error: Plugin/Preset files are not allowed to export objects, only functions. In /path/to/node_modules/babel-plugin-transform-dirname-filename/lib/index.js

The plugin exports a default object, but Babel 7 expects a function. This package is designed for Babel 6.

fix

Use Babel 6 or switch to @babel/plugin-transform-dirname-filename for Babel 7 compatibility.

SyntaxError: Unexpected token / in JSON at position 0

Using plugin in .babelrc with typographical errors (e.g., missing quotes or trailing comma).

fix

Validate .babelrc with a JSON validator or run npx babel --version to check config.
