Performance: string methods instead of new URL

[DarkCat09]

We'll get a really good performance boost if we replace new URL, which is used too much often as I see, with string methods. On the other hand, manually parsing URL in some cases is not simple and concise.

Benchmark code

const Benchmarkify = require("benchmarkify")

const benchmark = new Benchmarkify("Benchmark", { chartImage: true }).printHeader()

benchmark.createSuite("URL convert", { time: 10000 })

  .add("URL object", () => {
                const url = new URL("https://dc09.ru/posts/fediverse#comments")
                const hash = url.hash
                url.hash = ""
                return encodeURIComponent(url.toString()) + hash
        })

        .ref("String methods", () => {
                let url = "https://dc09.ru/posts/fediverse#comments"
                const hashIdx = url.indexOf("#")
                if (hashIdx != -1) {
                        return encodeURIComponent(url.substring(0, hashIdx)) + url.substring(hashIdx)
                }
                else {
                        return encodeURIComponent(url)
                }
        })

benchmark.run()

We can use fast-url-parser.

Benchmark code

const Benchmarkify = require("benchmarkify");
const furl = require("fast-url-parser");

const benchmark = new Benchmarkify("Benchmark", {
  chartImage: true,
}).printHeader();

  .createSuite("URL convert", { time: 10000 })
  .add("URL object", () => {
    const url = new URL("https://dc09.ru/posts/fediverse#comments");
    const hash = url.hash;
    url.hash = "";
    return encodeURIComponent(url.toString()) + hash;
  })
  .ref("Fast URL parser", () => {
    const url = furl.parse("https://dc09.ru/posts/fediverse#comments");
    const hash = url.hash;
    url.hash = "";
    return encodeURIComponent(url.toString()) + hash;
  })
  .ref("String methods", () => {
    let url = "https://dc09.ru/posts/fediverse#comments";
    const hashIdx = url.indexOf("#");
    if (hashIdx != -1) {
      return (
        encodeURIComponent(url.substring(0, hashIdx)) + url.substring(hashIdx)
      );
    } else {
      return encodeURIComponent(url);
    }
  });
