Serving Static Fields


We use the following statement to serve static fields

 app.use(express.static("public"));

app.use(express.static(path.join(__dirname,"public")));

index.js

const express = require("express");
const app = express();
const path = require("path");

const port = 8080;
app.use(express.static("public"));
app.use(express.static(path.join(__dirname, "public")));

app.set("view engine", "ejs");

app.set("views", path.join(__dirname, "/views"));
app.get("/ig/:username", (req, res) => {
  let { username } = req.params;
  const InstaData = require("./data.json");
  const data = InstaData[username];
  if (data) {
    res.render("insta.ejs", { data });
  } else {
    res.render("error.ejs");
  }
});
app.listen(port, () => {
  console.log(`server is listening on port ${port}`);
});


insta.ejs
