tsro/dist/utils/loadTsConfig.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.

import ts from "typescript";
import { dirname, resolve } from "node:path";
export const loadTSConfig = async (projectRoot, configFile, system) => {
    const configPath = resolve(projectRoot, configFile);
    const { config, error } = configPath
        ? ts.readConfigFile(configPath, system.readFile)
        : { config: {}, error: undefined };
    const { options, fileNames } = ts.parseJsonConfigFileContent(config, system, dirname(configPath));
    return { options, fileNames, configPath, error };
};
