Current repo's version is
This course has been completed on 26/01/2022 - Certificate

Why it has not any updated dependencies?

After finishing its related Udemy course, I archive this repository and unarchive it when I start a new training and add a link in the Other practice repos section referring to its new repo. But I don't update any associated dependency due to technology changes during the years between each practice, and the produced code which works with the mentioned requirements.

Requirements

Node v16.13.2 or above
A relational database (like PostgreSQL or MySQL, for example) (for 3-prisma)
pgAdmin or any relational database client (for 3-prisma)

Repo structure

1-exercises: Exercises related to Andrew's course.
2-apollo: Server and Client projects from Apollo's Tutorial to understand an end to end implementation.
3-prisma: Prisma learning and integration with a GraphQL server.
4-testing: How to create and run unit tests for a GraphQL server

Setup

After cloning the repo, go to the created folder and install the node packages.

git clone https://github.com/NicolasOmar/graphql-practice.git
cd graphql-practice
npm run setup-all

setup-all is the command to install all the projects, but if you want to do it one by one, you can change that last line for one of the following:

App Setup	Command
All	`npm run setup-all`
Exercises	`npm run setup-exercises`
Apollo tutorial	`npm run setup-apollo`
Prisma exercises	`npm run setup-prisma`
Unit testing	`npm run setup-testing`
