Ryan, thanks for pointing me in the right direction. I fleshed out your answer (2nd paragraph) a little bit with some code and it works. In this scenario these code snippets are put in my express app: // set up plain http server var http = express(); // set up a route to redirect http … Read more
The rewire module is definitely the answer. Here’s my code for accessing an unexported function and testing it using Mocha. application.js: function logMongoError(){ console.error(‘MongoDB Connection Error. Please make sure that MongoDB is running.’); } test.js: var rewire = require(‘rewire’); var chai = require(‘chai’); var should = chai.should(); var app = rewire(‘../application/application.js’); var logError = app.__get__(‘logMongoError’); … Read more
Express API reference covers this case. See status and send. In short, you just have to call the status method before calling json or send: res.status(500).send({ error: “boo:(” });
A quick solution from the internet search was npm config set strict-ssl false, luckily it worked. But as a part of my work environment, I am restricted to set the strict-ssl flag to false. Later I found a safe and working solution, npm config set registry http://registry.npmjs.org/ this worked perfectly and I got a success … Read more
In many environments (e.g. Heroku), and as a convention, you can set the environment variable PORT to tell your web server what port to listen on. So process.env.PORT || 3000 means: whatever is in the environment variable PORT, or 3000 if there’s nothing there. So you pass that to app.listen, or to app.set(‘port’, …), and … Read more
Which OS are you using? If it’s Ubuntu you’ll need to install the build-essential package: $ sudo apt-get install build-essential Then try to install the package again.
You can either set the timeout when running your test: mocha –timeout 15000 Or you can set the timeout for each suite or each test programmatically: describe(‘…’, function(){ this.timeout(15000); it(‘…’, function(done){ this.timeout(15000); setTimeout(done, 15000); }); }); For more info see the docs.
Per the Express (Version 4+) docs, you can use: res.status(400); res.send(‘None shall pass’); http://expressjs.com/4x/api.html#res.status <=3.8 res.statusCode = 401; res.send(‘None shall pass’);
You could also just overload the default console.log function: var fs = require(‘fs’); var util = require(‘util’); var log_file = fs.createWriteStream(__dirname + ‘/debug.log’, {flags : ‘w’}); var log_stdout = process.stdout; console.log = function(d) { // log_file.write(util.format(d) + ‘\n’); log_stdout.write(util.format(d) + ‘\n’); }; Above example will log to debug.log and stdout. Edit: See multiparameter version by … Read more
new Buffer(number) // Old Buffer.alloc(number) // New new Buffer(string) // Old Buffer.from(string) // New new Buffer(string, encoding) // Old Buffer.from(string, encoding) // New new Buffer(…arguments) // Old Buffer.from(…arguments) // New Note that Buffer.alloc() is also faster on the current Node.js versions than new Buffer(size).fill(0), which is what you would otherwise need to ensure zero-filling.
