Step by Step Express

The intent of this project is to take you step-by-step through the process of building an Express app, documenting the changes as bite-sized chunks that you'll ideally be able to pick up and iterate upon rapidly.

Step Zero

• Initalize the repo with the universal documents that we should have in every project

Read more in the Step Zero README.md

Step One

• Set up a very basic HTTP server + add the dependencies

To run the Step One code:

# make sure your current working directory is the main directory of this repo
cd step-one
node app.js

Read more in the Step One README.md

Step Two

• Set up a very basic HTTP server + add the dependencies

To run the Step Two code:

# make sure your current working directory is the main directory of this repo
cd step-two
node app.js

Read more in the Step Two README.md

Step Three

• Start parsing the querystring passed to the web app and – if the querystring id is present – passing that value to the API we're hitting, via the request module.

To run the Step Three code:

# make sure your current working directory is the main directory of this repo
cd step-three
node app.js

Step Four

• Add view rendering with handlebars (via express-handlebars)
• Create our first view
• Start rendering comics with handlebars on the /comic path

To run the Step Four code:

# make sure your current working directory is the main directory of this repo
cd step-four
node app.js

Read more in the Step Four README.md

Step Five

• Call Express's static method to serve CSS
• Create the /static directory + add our CSS file to it

To run the Step Five code:

# make sure your current working directory is the main directory of this repo
cd step-five
node app.js

Read more in the Step Five README.md

Step Six

• Add Added error handling
• Add port detection (process.env.PORT) that allows us to ship it to Auzre
• Add favicon.ico to make browsers happy

To run the Step Six code:

# make sure your current working directory is the main directory of this repo
cd step-six
node app.js

Read more in the Step Six README.md

Step Seven

• Dockerized
  • Add Dockerfile
  • Add .dockerignore
• Add host variable to detect if HOST environment variable is defined, defaulting to 0.0.0.0 if not.
  • Express now listens to the host as its host
• Add start npm script, which can be called with npm start

To run the Step Seven code:

# make sure your current working directory is the main directory of this repo
cd step-seven
node app.js
