Express not handling conditionals-CodePudding

I am new on Express. I have the following code:

const { response } = require("express");
const express = require("express");
const app = express();
app.get("/api/products/:id", function (req, res) {
  const id = req.params.id;

  if (id === 1) {
    res.json(id);
  }
});

However, every time I set the conditional if the server don't respond and just stay processing. Am I doing something wrong?

CodePudding user response：

req.params are always strings;

app.get("/api/products/:id", function (req, res) {
  const id = req.params.id;

  if (id === '1') { // look here, the single quotes around 1 -> '1'
    res.json(id);
  } else {
    res.json({message: 'Wrong param'}) // respond also if id is not '1', otherwise the client will still wait for a response when param is different by '1'
  }
})
