babel-plugin-transform-beautifier

0.1.1 verified Sat Apr 25 auth: no javascript deprecated

A Babel plugin (v0.1.1) that transforms JavaScript conditional expressions (ternary, logical AND/OR) into if/else statements for improved readability. It is a niche tool focused solely on beautifying ternaries, with no updates since 2021 and low maintenance. Unlike general formatters (Prettier) or codemods (jscodeshift), it performs a specific AST transformation. Intended for build-time use in Babel pipelines.

Common errors

error Error: Cannot find module 'babel-plugin-transform-beautifier' ↓

cause Package not installed or missing from node_modules.

fix

Run 'npm install --save-dev babel-plugin-transform-beautifier' and check your babel config plugin name.

error Plugin threw: 'babel-plugin-transform-beautifier' is not a valid plugin ↓

cause Using incorrect import syntax or missing plugin name as string.

fix

In babel.config.js, use plugins: ['babel-plugin-transform-beautifier'] (string, not a function or variable).

Warnings

deprecated Package is unmaintained since 2021. No support for modern Babel (v7.20+). Check for compatibility with your Babel version. ↓

fix Use an alternative like manual refactoring or a custom codemod.

gotcha Only transforms ternary expressions and logical AND/OR in conditional context. Does not beautify other patterns like nested ternaries or switch statements. ↓

fix Review transformed output manually; expected beautification may not apply.

gotcha Plugin may conflict with other Babel plugins that manipulate AST or formatting (e.g., minifiers, other transforms). ↓

fix Ensure plugin order and test output with other plugins in pipeline.
