Lightweight TypeScript library for type-safe errors-as-values

function withError(callback) {
    try {
        const result = callback();
        const isPromise = result instanceof Promise;
        if (!isPromise) return getSuccess(result);
        return result.then(getSuccess).catch(getFailure);
    } catch (error) {
        return getFailure(error);
    }
}
const getFailure = (error)=>({
        error: error instanceof Error ? error : new Error(String(error))
    });
const getSuccess = (data)=>({
        data
    });
export { withError };
