express使用html模板

app.js中代码

var createError = require('http-errors');

var express = require('express');

var path = require('path');

var cookieParser = require('cookie-parser');

var logger = require('morgan');

var bodyParser = require('body-parser');

var indexRouter = require('./routes/index');

var usersRouter = require('./routes/users');

var ejs = require('ejs');

var app = express();

// view engine setup

app.set('views', path.join(__dirname, 'views'));

app.set('view engine', 'html');

app.engine('html',ejs.__express)

app.use(logger('dev'));

app.use(express.json());

app.use(express.urlencoded({ extended: false }));

app.use(cookieParser());

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

app.use('/', indexRouter);

app.use('/users', usersRouter);

app.use(bodyParser.json())

app.use(bodyParser.urlencoded({

  extended: true

}))

// catch 404 and forward to error handler

app.use(function(req, res, next) {

  next(createError(404));

});

// error handler

app.use(function(err, req, res, next) {

  // set locals, only providing error in development

  res.locals.message = err.message;

  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page

  res.status(err.status || 500);

  res.render('error');

});

module.exports = app;

路由文件中的代码index.js

router.get('/',function(req,res){

    res.type('html')

    res.render('index')

})
