开始

后端

  1. cd tasklist && npm init #创建项目

  2. npm install mongojs express ejs body-parser --save

  3. touch server.js

    var express = require('express')
    var path = require('path')
    var bodyParser = require('body-parser')

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

    var port = 3000;
    var app = express();

    app.set('views', path.join(__dirname, 'views'));
    app.set('view engine', 'ejs');
    app.engine('html', require('ejs').renderFile);

    app.use(express.static(path.join(__dirname, 'client')));
    app.use(bodyParser.json());
    app.use(bodyParser.urlencoded({extended: false}));


    app.use('/', index);
    app.use('/api', tasks);

    app.listen(port, function () {
        console.log('Server started on port' + port)
    });
  1. mkdir routes && cd routes

  2. touch index.js

    var express = require('express')
    var router = express.Router();

    router.get('/', function (req, res, next) {
        res.render('index.html');
    });
    module.exports = router;
  1. mkdir views && cd views && touch index.html

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
        HELLO WORLD
    </body>
</html>
  1. touch tasks.js

var express = require('express')
var router = express.Router();
var mongojs = require('mongojs')
var db = mongojs('mongodb://localhost:27017/nodeapp', ['tasks'])

router.get('/tasks', function (req, res, next) {
    db.tasks.find(function (err, tasks) {
        if (err) {
            res.send(err);
        }
        res.json(tasks);
    });
});

router.get('/task/:id', function (req, res, next) {
    db.tasks.findOne({_id: mongojs.ObjectId(req.params.id)}, function (err, task) {
        if (err) {
            res.send(err);
        }
        res.json(task);
    })
});

router.post('/task', function (req, res, next) {
    var task = req.body;
    if (!task.title || !(task.isDone + '')) {
        req.status(400);
        res.json({
            "error": 'Bad Date'
        });
    } else {
        db.tasks.save(task, function (err, task) {
            if (err) {
                res.send(err);
            }
            res.json(task);
        });
    }
});

router.delete('/task/:id', function (req, res, next) {
    db.tasks.remove({_id: mongojs.ObjectId(req.params.id)}, function (err, task) {
        if (err) {
            res.send(err);
        }
        res.json(task);
    })
})

router.put('/task/:id', function (req, res, next) {
    var task = req.body;
    var updTask = {};

    if (task.isDone) {
        updTask.isDone = task.isDone;
    }
    if (task.title) {
        updTask.title = task.title;
    }
    if(!updTask) {
        res.status(400);
        res.json({
            "error": 'Bad Data'
        })
    } else {
        db.tasks.update({_id: mongojs.ObjectId(req.params.id)}, updTask, function (err, task) {
            if (err) {
                res.send(err);
            }
            res.json(task);
        });
    }
})

module.exports = router;
