Module http da ke jiya a cikin Node zai iya ƙirƙira wajen yanar gida ba tare da ƙarewa ba. A gaske, maf'idoyin gida kaifi su amfani da tsarin irin Express a kansu, amma fahimtar toshe tushen — sai za ka fahimta abin da tsare ke aiki don ka.

Fillushi ya yi aiki domin kowa ajiya. Ka binciki req (url, method, headers) kuma ka rubuta zuwa res (status, headers, body). Lura da cewa ka kulli hanya da parsing gagarau da kannu.
let body = "";
req.on("data", chunk => body += chunk); // body arrives in chunks
req.on("end", () => {
const data = JSON.parse(body); // parse once fully received
});
Tare da toshe http, ma karanta jiki na ajiya ma zai nufin karbar gutsutsu na ruwan ruwan — maru, wanda jiya ne daidai abin da tsare ke ƙirƙira daga nesa.
import express from "express";
const app = express();
app.use(express.json()); // body parsing handled for you
app.get("/", (req, res) => res.json({ message: "Hello" })); // routing handled
app.post("/users", (req, res) => res.status(201).json(req.body));
app.listen(3000);
Express yana ƙara hanya, karbar jiki, tsarake na tsakani, da masu taimakon jiya (res.json, res.status) — canja da manyan layi na toshe http code.
Module http shine tushe wanda kowa imel na yanar gida Node ke ƙura a kansu.
Sanin yadda ake ƙirƙira toshen tushe — kuma ganinsa abubuwan sauri wanda ake buƙata (hanya ta binciki req.url/req.method, ƙarba gutsutsu na jiki, saita headers) — ya kayyade abin da tsare irin Express ke ƙara (hanya, karbar jiki, tsarake na tsakani, masu taimakon).
Wannan fahimta tana taimaka maka error a daidaita matakin kuma ta gane fa me yasa tsare suka zama sauri na gaske don ainihin softwear, wajen toshe http ya ci gaba da kasancewa mai amfani ga ayyukan jiya ko koyon tushe.
