DWD Wk 3

In class notes:

git branch  (tells you what branch you are on)
git status (gets status/tells you where you are)
git checkout master (goes back to master)
git checkout -b (creates new branch)
touch.gitignore (create .gitignore file)
touch "filename" (creates a new file)


Steps for creating branch:
1. git branch fileName
2. git checkout (like cd for branches)
3. git add .
4. git commit (push locally)
5. git push (push to github)
  • need to put node modules as git ignore

 

Helpful Resources:

 

Heroku Notes:

  • easily create sites
  • heroku takes our packages –> hosts at new url for us
git push heroku master
heroku logs -t

heroku needs below code in js file: 
"var port = process.env.PORT || 8000;"

 

SQL Notes:

  • SQL stores database for you. SQL Database is a set of tables, like a spreadsheet.
  • Different SQL datatypes: numbers, strings, binary data (just use text field)
  • Connect to database, define fields
  • Talk to it through node. Need to install database client library
  • One database per project
  • psql connects: a terminal-based front-end to PostgreSQL. It enables you to type in queries interactively, issue them to PostgreSQL, and see the query results. Alternatively, input can be from a file or from command line arguments.

SQL Steps:

  • in command line: Brew install postgresql
