view-engine

我已经安装了hbs而不是把手来进行动态模板制作，现在我陷入了这个问题。

Error: Failed to lookup view "index" in views directory "/home/trijay/Desktop/NodeJs/web-server/src/views"

下面是我的app.js代码，并且我已经安装了hbs Express库。任何帮助将不胜感激

// app.js

const express = require('express')
const path = require('path')


const publicPath = path.join(__dirname,'../public')   //for accessing comeplete file

const app = express()   //express being initialised


app.use(express.static(publicPath))
app.set('view engine','hbs')    //use to set handle bars. we need to provide key value pair

app.get('',(req,res) => {
    res.render('index')             //need to provide the hbs file name which you will find in view
})


app.get('/weather',res) => {
    res.send({
        latitude: -57.89,longitude: 78.42,location : 'New Delhi'
    })

})

app.listen(3000,() => {
    console.log('Server Started on port 3000')
})
