Babel Loader Transpiler Cache (node_modules/.cache/babel-loader)

Bottom Line: It is 100% safe to delete node_modules/.cache/babel-loader. Deleting it will NOT delete your React JSX, TypeScript, or JavaScript source code.

What is the babel-loader Cache Folder?

Located at node_modules/.cache/babel-loader in JavaScript projects, this directory is created by Babel Loader when configured with cacheDirectory: true.

Babel transpiles modern ES6+, JSX, and TypeScript code into browser-compatible JavaScript. To avoid re-transpiling thousands of files on every build, Babel saves compiled AST representations into babel-loader. Over active web development, this folder expands to 1 GB to 5 GB+.

• No source code loss: Your src/ files and .babelrc configuration remain 100% safe.
