const routes = [
  { path: "/a/b/c" },
  { path: "/a/b" },
  { path: "/d/:att1/e/:att2" },
  { path: "/d/:att1/e" },
  { path: "/" }
];

const compiled = compile(routes);

matcher(compiled "/a");                   // undefined
matcher(compiled, "/a/b");                // routes[1]
matcher(compiled, "/a/b/c");              // routes[0]
matcher(compiled, "/d/value1/e");                 // routes[3] { att1: "value1" }
matcher(compiled, "/d/value1/e/value2?sort=asc"); // routes[2] { att1: "value1", att2: "value2" }
matcher(compiled, "/");                           // routes[4]

With wildcards

import { compile, matcher } from "multi-path-matcher";

const routes = [
  { path: "/" },
  { path: "/*" },
  { path: "/about" },
  { path: "/login" }
];

const compiled = compile(routes);

matcher(compiled, "/");                   // routes[0]
matcher(compiled, "/index.html");         // routes[1]
matcher(compiled, "/about");              // routes[2]
matcher(compiled, "/login?param=1");      // routes[3]
