Waa Maxay backend?

Sharaxaad

Marka aad frontend baratay, tallaabada xigta waa backend-ka. Waxaad ka bilaabaysaa database-ka: sida xogta loo qaabeeyo, loo kaydiyo, loona soo raadiyo. Kadib waxaad dhisaysaa server, badanaa Node.js iyo Express, oo routes leh: mid xogta soo qaadaya, mid cusub abuuraya, mid beddelaya, mid tiraya. Ugu dambayn, backend-ka iyo frontend-ka ayaad isku xiraysaa; markaas ayaad noqonaysaa qof full stack ah oo app dhamaystiran internet-ka saari kara.

Backend-ku wuxuu qabtaa shaqooyinka aan client-ka lagu aamini karin: authentication, ogolaanshaha rol-ka user-ka, xisaabinta lacagta iyo credits-ka, wicitaanka API-yada dibadda, iyo qarinta keys-ka. Sidoo kale wuxuu qabtaa shaqooyinka culus ee gadaal ka socda, sida emails-ka la diro iyo hawlaha jadwalka leh. Xirfadaha xiga marka aasaasku dhammaado waa TypeScript, testing, caching iyo deployment-ka. Waa dhinaca ay ku jiraan go'aannada ugu muhiimsan ee mashruuca.

Tusaale

Copy
app.post("/api/orders", async (req, res) => {
  const user = await hubiUser(req);
  if (!user) return res.status(401).json({ khalad: "Ma gelin" });
  const order = await Order.create({ user: user.id, ...req.body });
  res.json(order);
});

Codsigu wuu yimid, user-ka ayaa la hubiyay, xogtii ayaa database-ka gashay, jawaabna waa la soo celiyay. Hubinta halkaas ayay ku jirtaa, ma aha browser-ka.
