Advanced tools
Package description
The @babel/plugin-transform-member-expression-literals package is a Babel plugin that transforms member expressions with literal properties into a form that can be more efficiently minimized. This means that it will convert object properties accessed with a literal (e.g., obj['property']) into dot notation (e.g., obj.property), which can be shorter and more optimized in the context of JavaScript code minification.
Transform member expressions with literal properties to dot notation
This feature automatically converts member expressions that use literal strings for accessing properties into dot notation. This is particularly useful for code minification and optimization.
obj['property'] // Before transformation
obj.property // After transformationSimilar to @babel/plugin-transform-member-expression-literals, this plugin focuses on transforming object properties that are literals into a more minifiable form. However, it specifically targets properties in object definitions rather than member expressions. It's another tool in the Babel ecosystem for optimizing JavaScript code.
While not a Babel plugin, uglify-js is a widely used JavaScript minifier that includes transformations similar to what @babel/plugin-transform-member-expression-literals offers. It can convert member expressions with literal properties into dot notation as part of its minification process, among many other optimizations.
