# Week 10

Quick Takes on Important Web Dev Topics

*Sit with your project groups*

----

# Project 2

- Project 2 due in less than 2 weeks (12/2)! Start Coding!
- Identify your Minimum Viable Product (MVP)
- Assure that tasks and expectations are clearly defined
- Reach out as you need help! Checkoffs are happening

----

# Project Presentations

- Will be in exactly 2 weeks, next class
- Live presentation: If your code is deployed and very difficult to error
- Videos: Everyone else. Saves us time from the inevitable random errors
- Videos will be due prior to class

---

# Deployment

----

# What happens when you run 'rails server'

- You are hosting a webserver on your own computer
- The real world can't send requests to your computer!
- Heroku = great service to host on someone else's computers

----

# Did our heroku deploy work??

---

# HTML and CSS: A Super Cursory Overview

----

# Disclaimer

- We mention this part of web dev because it's important
- Still not within the explicit scope of the class
- TA's won't necessarily be able to help

---

# Webhooks!

----

# What are they?

- Usually we get requests from users
- Can tell other webservers to ping you!
- It's two SERVERS talking to eachother, not users
- Messenger Bot, Github, IFTTT
- [Damn I love the internet](https://github.com/realadeel/awesome-webhooks)

# Facebook Messenger Bot

----

# Building a Facebook messenger bot

1. When someone sends this bot a message, facebook will send you a request
2. That request will give you a conversation ID
3. Your Bot sends POST request to facebook with conversation ID and response

----

# Overview

Step 1: Add a route and controller for messaging

Step 2: Tell facebook to send us messages at that route

Step 3: Parse requests and get conversation data

Step 4: Use faraday to respond via a POST request!

----

# Connecting to Facebook

Step 1: Register on Facebook

Step 2: Create new Whales app

Step 3: Set up routes and test receiving messages!

Step 4: Use faraday to send back messages with a POST request!

# Moral of the story:

> You don't need to have read every book to be resourceful. Knowing that the library exists and how to read its catalog is good enough
- The web is so much more fun when you're not alone
- "There's an App for that" => "There's an API for that"

# Project Work Time

- Make sure to split tasks with your team
