Implemented User registration and authentication mechanism along with JWT access token and refresh token mechanism using Node, Express, GraphQL

About GraphQL

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

Libraries Used:

1. apollo-server-express
2. graphql
3. express
4. mongoose
5. bcryptjs
6. jsonwebtoken
7. joi
8. nodemon
9. dotenv

ES Modules in Node

We us ECMAScript Modules in the backend in this project. Be sure to have at least Node v14.6+ or you will need to add the "--experimental-modules" flag.

Also, when importing a file (not a package), be sure to add .js at the end or you will get a "module not found" error.

You can also install and setup Babel if you would like.
