Playground for working with graphql & mongodb

GraphQL & MongoDB exploration

This project is Evan's exploration into writing an Apollo Server based graphQL & Mongo DB integration.

Installation

Prerequisites

• Node v12 & npm 6.x.x

Installation

Set up environment variables for:

• MONGO_DB_USER
• MONGO_DB_PASSWORD

Note: The MONGO_DB_PASSWORD will act as the JWT private signature for the tokens generated from this service. This means tokens are not valid across multiple service instances unless authenticated with the same credentials.

Within the project directory: npm i

Start

npm start

Usage

npm start will spin up the database connection to the MongoDB cluster running in the cloud. This will be served on the port defined in .env (currently set to 4000).

GraphQL playground will be hosted at http://localhost:4000/graphql.

Current operations are all User based, including creating and updating user entries. These operations have access controls in which modifications/reads to a created user can only be done by said user.

The front end code runs on http://localhost:8080.

Authenticating

Receiving a jwt token from the service is done by making a post request to http://localhost:4000/login with the appropriate username and password combination.

The jwt is encoded and signed to work within the service that is running. To utilize the token, add it to the Authorization header as Bearer {token}.
