home.ejs

如果我们在项目文件的外面的路径运行整个程序会出错：那么如果我们想在任何地方正常运行这个程序呢？
——use views directory
index.js const express = require(‘express‘); const app = express(); const path = require(‘path‘); // tell my app to use express, the teacher is ejs // we don‘t need to require ejs, just set the engine view to ejs app.set(‘view engine‘, ‘ejs‘) app.set(‘views‘, path.join(__dirname, ‘/views‘)) //__dirname is where index.js is located app.get(‘/‘, (req, res) => { res.render(‘home.ejs‘) }) app.listen(3000, () => { console.log("Listening On Port 3000") })
then it will work fine.
