Identify and use libraries for software projects

For this example we will be looking at Kelsey’s Galvanize Games, she used express, path, serve-favicon, morgan, cookie-parser, body-parser, method-override, dotenv, hbs, knex, and pg.

• express – is the server framework that allows us to do simple routing and support for connecting middleware.
• path – module providing utilities to set file and directory paths.
• serve-favicon – middleware for serving a favicon.
• morgan –  is used for logging request details.
• cookie-parser – parse cookie header and populate req.cookies with an object keyed by the cookie names. Optionally you may enable signed cookie support by passing a secret string, which assigns req.secret so it may be used by other middleware.
• body-parser – parses request bodies and in this repos case it parses the data into json. This is needed so that we will have manipulatable data when we make a call to our database in a json format.
• dotenv – stores configuration in the environment separate from code. this is necessary to seperate how the code runs when not run locally using the specified variables put into dotenv.
• hbs – is the view engine to display data, this allows us to use html syntax like normal to structure the layout of UI
• knex – is the SQL query builder that allows easy communication between expresss and our db.
• method-override allows us to use PUT, PATCH, DELETE so that we can do more than just GET and POST
• pg – is the relational database used to store and manipulate the data tables.
