Sticky Regex Rewriter

Build a Babel plugin that enforces a Babel 7+ requirement and rewrites sticky regex literals into equivalent constructor calls while leaving other regex literals untouched.

Capabilities

Sticky literal rewriting

• Input const r = /foo/y; becomes const r = new RegExp("foo", "y"); @test
• Input const r = /foo/gy; becomes const r = new RegExp("foo", "gy"); @test

Non-sticky passthrough

• Input const r = /foo/g; stays const r = /foo/g; @test

Babel version gate

• Loading the plugin with a Babel major version below 7 throws a clear error explaining that Babel 7 or later is required. @test

API

export function transformSource(code: string): string;
// returns the transformed source code string after applying the plugin
export function transformFile(filePath: string): string;
// reads a file, applies the same transformation, and returns the transformed code

Dependencies { .dependencies }

@babel/plugin-transform-sticky-regex { .dependency }

Rewrites regex literals using the sticky flag into equivalent RegExp constructor calls while preserving pattern text and all flags. Use this dependency to perform the transformation rather than reimplementing the same logic manually. @satisfied-by
