Demo code and slides from my talk "Taming Asynchronous Programming (beyond Promises)"

Description

This project contains the slides for my talk about asynchronous programming with JS and the code samples.

If you want to play with the code, download this project and follow the build instructions.

You can change the port the server is listening

Build

• Install MongoDB if you already don't have it.
• Install NodeJS if you already don't have it (at least 0.8, but I recommend latest stable version).
• Install Grunt 0.4 npm install -g grunt-cli if you already don't have it.
• Change to the code/ directory and issue npm install command.
• Change to the code/lib/es directory and issue npm install command in that directory.
• Go back to code/ and issue grunt command.

Installing and starting the sample DB

• Change to the code/ directory
• Unpack db/sampledb.zip. A sampledb/ directory should appear under db/
• From code/ start mongo with mongod --dbpath db/sampledb/

Starting the server

• From code/ issue node lib/server.js to start the server
• You can access the UI in the following URLs: http://localhost:8081/frp .html, http://localhost:8081/es .html, http://localhost:8081/fp.html and http://localhost:8081/rx.html
• Each URI is the same application but implemented with different approaches
• Try to search for red, shoe, bag, white, etc.

Custom settings

• Change the file config/settings.json and restart the server
• This file contains the configuration for the server:

{
  "dbString":"mongodb://[user:password]@localhost:[port]/sample?w=1",
  "port":[the port nodejs server is listening to],
  "delay":[a delay in milliseconds to emulate network latency, must be > 1]
}
