The following is a sample of a readme Setup section for a node postgres stack:

Setup

Clone this repository to your local machine
Install the dependencies for the project
Ensure your PostgreSQL server is running
Create a User for this exercise
Create a database for the exercise with your user as the owner
Copy [do not rename] the example.env file as .env and update .env with the following fields with your database credentials:

Core status codes -- can look at as a checklist when building API

2XX - success case
- 200 - Success - good for GET, often the default https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/200
- 201 - Created - good for POST https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/201
- 204 - No content - successful, BUT server does not send you information besides an "OK, your request succeeded, 204." Sometimes used on create, never used to get data, but more often for liveness endpoints (endpoints checked every 1 second - 10 minutes that just serve to respond "OK 204 I am alive" for monitoring) like www.something.com/health-check, which is used by monitoring or even sites like IsItDown.com - https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/204
4XX - any missing or inacessable resource case "Oops you screwed up."
400 - Invalid Request - textbook "you screwed up". Example route /users/123 exists and accepts params. Howevewr the param must be a number and someoneo does /use

Back to School Shopping Live Interview problems

Welcome to the live interview! We'll be taking this problem set and working on a few additional problems.

Prompt 1 - Find Items

You want to know which items are of the same type. Create a function called findItems that takes the array of items and a type of item as parameters and returns an array of item names.

Interview: Science Questions

You will be writing one additional function to help analyze responses for a science quiz. You will then add a feature onto that function. Your interview will help guide you through this process. As a reminder, each response is represented as an object with the following keys:

question - the question that was asked, represented as a string.
response - the response that was given, represented as a string.
correct - whether or not the response was graded as correct, represented as a boolean.
isEssayQuestion - whether or not the response is an essay question, represented as a boolean.

Data for the entire month is stored in an array. For example:

Building A New File Based Data Connector/Processor

In order to process files of a new type, such as a new type of test we've never processed before, you'll have to define how to process that file within this module. Here are some steps that may help you accomplish this. The majority of this work will occur in the file ~/SzfdData/config/module.config.php and other areas of the SzfdData module.

It is a prerequisite that you have access to our szf code repository to perform these steps. Please get in touch with Jake Alves or another lead engineer to get access to this code repo.

1: Create a schema file by looking at the file you are trying to upload

Some academic tests contain help documentation for the test reports they issue, and some tests do not provide such documentation. Here is an example of the California State Test's documentation for their testing reports.
