Note: This describes how Express worked in versions 2 and 3. See the end of this post for information about Express 4. static simply serves files (static resources) from disk. You give it a path (sometimes called the mount point), and it serves the files in that folder. For example, express.static(‘/var/www’) would serve the files … Read more
Easiest way I know of is to use “child_process” package which comes packaged with node. Then you can do something like: const spawn = require(“child_process”).spawn; const pythonProcess = spawn(‘python’,[“path/to/script.py”, arg1, arg2, …]); Then all you have to do is make sure that you import sys in your python script, and then you can access arg1 … Read more
You can have jade include a plain HTML page: in views/index.jade include plain.html in views/plain.html <!DOCTYPE html> … and app.js can still just render jade: res.render(index)
Try adding the following middleware to your NodeJS/Express app (I have added some comments for your convenience): // Add headers before the routes are defined app.use(function (req, res, next) { // Website you wish to allow to connect res.setHeader(‘Access-Control-Allow-Origin’, ‘http://localhost:8888’); // Request methods you wish to allow res.setHeader(‘Access-Control-Allow-Methods’, ‘GET, POST, OPTIONS, PUT, PATCH, DELETE’); // … Read more
If you don’t feel like iterating, try FBFriendModel.find({ id:333 }).remove( callback ); or FBFriendModel.find({ id:333 }).remove().exec(); mongoose.model.find returns a Query, which has a remove function. Update for Mongoose v5.5.3 – remove() is now deprecated. Use deleteOne(), deleteMany() or findOneAndDelete() instead.
There are a few ways of passing data around to different routes. The most correct answer is, of course, query strings. You’ll need to ensure that the values are properly encodeURIComponent and decodeURIComponent. app.get(‘/category’, function(req, res) { var string = encodeURIComponent(‘something that would break’); res.redirect(‘/?valid=’ + string); }); You can snag that in your other … Read more
Try http://localhost:3001/default.css. To have /styles in your request URL, use: app.use(“/styles”, express.static(__dirname + ‘/styles’)); Look at the examples on this page: //Serve static content for the app from the “public” directory in the application directory. // GET /style.css etc app.use(express.static(__dirname + ‘/public’)); // Mount the middleware at “/static” to serve static content only when their … Read more
app.js var express = require(‘express’), dogs = require(‘./routes/dogs’), cats = require(‘./routes/cats’), birds = require(‘./routes/birds’); var app = express(); app.use(‘/dogs’, dogs); app.use(‘/cats’, cats); app.use(‘/birds’, birds); app.listen(3000); dogs.js var express = require(‘express’); var router = express.Router(); router.get(“https://stackoverflow.com/”, function(req, res) { res.send(‘GET handler for /dogs route.’); }); router.post(“https://stackoverflow.com/”, function(req, res) { res.send(‘POST handler for /dogs route.’); }); module.exports … Read more
It passes control to the next matching route. In the example you give, for instance, you might look up the user in the database if an id was given, and assign it to req.user. Below, you could have a route like: app.get(“https://stackoverflow.com/users”, function(req, res) { // check for and maybe do something with req.user }); … Read more
If you are running behind a proxy like NGiNX or what have you, only then you should check for ‘x-forwarded-for’: var ip = req.headers[‘x-forwarded-for’] || req.socket.remoteAddress If the proxy isn’t ‘yours’, I wouldn’t trust the ‘x-forwarded-for’ header, because it can be spoofed.
