tsro/dist/utils/checkLib.js

TypeScript Remove Orphaned (tsro) is a CLI utility and library for TypeScript projects that detects and removes files containing invalid imports — imports that refer to nonexistent entities or nonexistent modules.

export const checkLib = (importPath, aliases) => {
    const aliasPattern = aliases.map((alias) => alias.replace("*", "(.*)"));
    const match = importPath.match(new RegExp(`^${aliasPattern}$`));
    const isSourceFile = importPath.startsWith("./") || importPath.startsWith("../") || match;
    return !isSourceFile;
};
