Getting Setup

Installing project dependencies

This project uses NPM to manage software dependencies. NPM Relies on the package.json file located in the root of this repository. After cloning, open your terminal and run:

npm install

tip: npm i is shorthand for npm install

Installing useful tools

1. Postbird

Postbird is a useful client GUI (graphical user interface) to interact with our provisioned Postgres database. We can establish a remote connection and complete actions like viewing data and changing schema (tables, columns, ect).

2. Postman

Postman is a useful tool to issue and save requests. Postman can create GET, PUT, POST, etc. requests complete with bodies. It can also be used to test endpoints automatically. We've included a collection (./udacity-c2-restapi.postman_collection.json ) which contains example requsts.

Running the Server Locally

To run the server locally in developer mode, open terminal and run:

npm run dev

Developer mode runs off the TypeScript source. Any saves will reset the server and run the latest version of the codebase.
