i am new to backend web development and i was practicing on a project in nodejs and express.js Below is the code of my app.js file
const express = require("express")
const bp = require("body-parser")
const app = express()
app.set("view-engine", "ejs")
app.get("/", (req, res) => {
const date = new Date()
const curDay = date.getDay()
let day = ""
if (curDay === 6 || curDay === 0){
day = "weekend"
} else{
day = "weekday"
}
res.render("list", {kindOfDay: day})
})
app.listen(3000, () => {
console.log("Listening on port 3000")
})
And below is the code of my list.ejs file
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta charset="UTF-8">
<title>To-Do List App</title>
</head>
<body>
<h1>It's a <%= kindOfDay %>!</h1>
</body>
</html>
When i try to run the app using nodemon app.js command it throws me an error back which says
Error: No default engine was specified and no extension was provided. at new View (/storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/view.js:61:11) at Function.render (/storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/application.js:570:12) at ServerResponse.render (/storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/response.js:1012:7) at /storage/emulated/0/todo-list-app-ver_1/app.js:15:7 at Layer.handle [as handle_request] (/storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/router/layer.js:95:5) at next (/storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/router/route.js:137:13) at Route.dispatch (/storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/router/route.js:112:3) at Layer.handle [as handle_request] (/storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/router/layer.js:95:5) at /storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/router/index.js:281:22 at Function.process_params (/storage/emulated/0/todo-list-app-ver_1/node_modules/express/lib/router/index.js:335:12)
Expected output should be
it's a weekday
or
it's a weekend
i don't know what's causing the error. My node version is 16.13.0 and my express version is 4.17.1
You have typo in app.set("view-engine", "ejs") instead should be app.set("view engine", "ejs") and it Works like a charm ;-)
const express = require("express");
const app = express();
app.set("view engine", "ejs");
app.get("/", (req, res) => {
const date = new Date();
const curDay = date.getDay();
let day = "";
if (curDay === 6 || curDay === 0) {
day = "weekend";
} else {
day = "weekday";
}
res.render("list", { kindOfDay: day });
});
app.listen(3000, () => {
console.log("Listening on port 3000");
})
