Getting Started

You will need to install the following in order to get this project up & running locally

• Node.js
• pnpm
• NVM
• Docker

use correct package manager and npm versions

Corepack is a tool installed as part of your Node.js installation that allows you to install and manage multiple package manager versions in your environment based on per-project configuration (via the packageManager field in package.json).

We use corepack to ensure that everyone is using the same version of PNPM to avoid any issues when people are using different versions of PNPM.

corepack enable
nvm install
nvm use

If for some reason the above corepack command doesn't work, you can install PNPM manually by running:

PNPM_VERSION=$(node -e "console.log(require('./package.json').engines.pnpm)")
curl -fsSL https://get.pnpm.io/install.sh | env PNPM_VERSION=$PNPM_VERSION sh -

This will install the package manager version specified in the package.json file. You can check that this has been installed by running:

pnpm -v

Install dependencies

Install the project's PNPM dependencies by simply running:

pnpm i

Running the server

cd into the api directory for the following commands

cd apps/api

setup databases

docker-compose up

you will then need to generate the prisma client and run migrations to create the tables in your database

pnpm db:generate && pnpm db:migrate

start the server

pnpm dev

You can validate that the server is running by visiting http://localhost:8000/api/healthcheck in your browser. If everything is setup ok, you should see a response with the following body:

{
  db: true,
  cache: true,
  status: "OK"
}

Documentation

Documentation of all endpoints can be found by visiting http://localhost:8000/docs. We use zod-to-openapi to transform the validation schemas that the server uses into openAPI specs for swagger to present

Running integration tests

pnpm t

This will setup the test database, run the integration & unit tests, and then finally reset the test database.

Running end-to-end tests

First you'll need to install playwright browsers if you haven't already

make e2e-install-browsers

Run all tests

make e2e-local

Run one test

tests=test-name make e2e-local
