A progressive Node.js framework for building efficient and scalable server-side applications.

👉 Description

Try to fix bugs:

• ✔️ client side fetch graphql api
• ❌ server side(SSG) FAIL to fetch graphql api
• ❌ postman FAIL to fetch graphql api

👉 Usage

Init

Follow ./env/example.env to define env variables. Make sure you have .env, developmnet.env and production.env files set up.

Also, mongo db have different URI format by version. Our .env is following the second one. See more on config.service.ts

# 1. mongodb://[username:password@]host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[database][?options]]
# 2. mongodb+srv://[username:password@]host[/[database][?options]]

Test w/ JWT auth guard

In GraphQL Playground add the http header as below, when testing protected GQL query / mutation, which is only accesible after authentication

{
	"Authorization" : "Bearer <encodedJWT>"
}

• Crash Course - First taste
• Crash Course - w/ MongoDB
• Crash Course - mongoose -- my notes
• Crash Course - Authentication

notion	note
module
ㄴ Contorller	handling incoming requests and returning responses
ㄴ Provider	service you provide, called by controller
ㄴ Model	as a class property
ㄴ ❓imports
❓Interceptors	@injectable()

Coding strategy

1. Write method in Controller (.controller.ts) 🡪 What's the req and res
2. Write method in Provider (.service.ts) 🡪 How to impliment the logic like how to process datas from db and return them.
