This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).

### Getting Started

When first getting set up you'll firstly want to install the existing dependencies. To do this, simply run

```bash
npm install
# or
yarn install
```

First, run the development server:

```bash
npm run dev
# or
yarn dev
# or
pnpm dev
```

Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.

This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.

## Learn More

To learn more about Next.js, take a look at the following resources:

- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.

You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!

## Deploy on Vercel

The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.

Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.

We currently have a development version, found at https://assessment-model-dev.vercel.app, and a production version at https://assessment-model.vercel.app, however the production version is missing a significant number of environmental variables, which will need to be added.

# Drizzle ORM

We're using Drizzle ORM to interface with our AWS Postgres database. Documentation on getting set up can be found [here](https://orm.drizzle.team/docs/installation-and-db-connection/postgresql/node-postgres)

## Schemas

In order to get started with Drizzle, a schema needs to be created. Schemas can be added src/app/db/schema as typescript files. See the documentation on how to set
up schemas but effectively, Drizzle allows you to define schemas as typescript code, which allows for simple, type safe schema definitions.

## Creating Migrations

To create a migration, a command has been set up in package.json. Simply run

```bash
npm run migration:generate
```

Or with yarn/pnmp accordingly.

Note, there seems to be a bug with Drizzle which is documented [here](https://github.com/drizzle-team/drizzle-orm/issues/803).

The workaround is to open up `tsconfig.json` and comment out `"target": "es5"`, and replace it with `"target": "ESNext"`. This should hopefully only
be a temporary workaround required.

## Pushing migrations

To push migrations, another command has been set up in package.json, since drizzle-kit currently does not support pushing for Postgres out of the box.

Run

```base
npm run migration:push
```

Which will commit changes to the database. The database changes will be pushed to the **public** schema, whereas a meta record will be pushed to the **\_\_drizzle_migrations** schema.

## Inserting users into the database

In order to insert a user into the database, simply run

```
npm run create_users -- {email} {firstName}
```

Since we're using just the built in process arguments to read command line arguments, the ordering of arguments needs to be email address and then name

# Cypress Testing Documentation

This document provides an overview of how to perform end-to-end testing using Cypress for the login functionality of the application. The testing code is based on the provided code snippets.

## Prerequisites

Node.js installed on your machine
Cypress installed as a dev dependency in your project

## Test Execution

To execute the login tests, follow these steps:

1. Run

```bash
npm run test:e2e:open
```

Which will open Crypress test runner

2. Select the tests that you want to run. At the time of writing, only login tests have been completed

## Key files

The key files that are at play for testing are documented here. Because of some issues testing next-auth and setting cookies, a custom command to set
the JWT, and avoid the functionality defined in the signIn function as defined in `src/app/api/auth/[...nextauth]/route.ts`

**cypress/plugins/index.js** is a standard file, required by cypress to journey through the Google Oauth flow

**cypress/figtures/session.json** is a user fixture that is used to log in a user in the login tests

**cypress/support/commands.ts** creates a custom login user command which sets a JWT and allows us to actually authenticate. `cy.intercept` only mocks the client side behaviour of the apis and therefore does not set any cookies, do this function does this manually.

# Generating pre-signed urls

In our terraform stack, we have a module called `s3_presignable_bucket` which contains the definition for our bucket which we will use to store retrofit plan input csv's in.

We will generate a pre-signed url and then make a post request to that endpoint to store that data to s3. Part of that process is the creation of an AWS IAM role which contains
the permission set to access the bucket, `rerofit-plan-inputs-<stage>`. The name of this IAM role is `s3_presign_role_<stage>` and for our NextJS application, as it's hosted outside of AWS (for the moment), we need to generate a set of access credentials to give the application access to this bucket. The access key and secret key are automatically generated and stored in AWS secrets manager under `dev/presign_frontend/access_key` and `dev/presign_frontend/secret_key` and need to be set in the environment for the pre-sign api to store csv data to aws.
