• This file contains all the required modules, establish the mongoose connection and GraphQL file contains mongoose user schema model that represents set of informations for user record in database.
• js hereâ€s an example of a user type that define GraphQL User Schema.
• js file write a very simple GraphQl user query and mongoose query used inside to retrieve user list of data from mongodb database.
• # Create New User – Creating a new user add a mutation with fields of user name args and resolve method which will be invoked by the GraphQL execution engine in order to create user for the request.
• # Update User – Update existing user we create a mutation with fields of user ID and username that we need to update and resolve method which will be invoked by the GraphQL execution engine in order to update user for the request.

@CloudBoostio: A CRUD app with Apollo, GraphQL, #NodeJs, Express, MongoDB, Angular (v5)
#JavaScript

Nowadays I’ve started learning GraphQL from a big brother’s inspiration. And trying to make a simple CRUD application using Apollo, GraphQL, NodeJs, Express, MongoDB, Angular5.

GraphQL is a data query language developed internally by Facebook in 2012 before being publicly released in 2015. It provides an alternative to REST and ad-hoc web service architectures. It allows clients to define the structure of the data required, and exactly the same structure of the data is returned from the server. It is a strongly typed runtime which allows clients to dictate what data is needed. This avoids both the problems of over-fetching as well as under-fetching of data.

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. Send a GraphQL query to your API and get exactly what you need, nothing more and nothing less. GraphQL queries always return predictable results. Apps using GraphQL are fast and stable because they control the data they get, not the server.

Before starting, Verify that you are running at least node 6.9.x and npm 3.x.x by running node -v and npm -v in a terminal/console window. Older versions produce errors, but newer versions are fine.

Now let’s talk about the Github Repo, you will see two folders, one is for the client side that build by latest version of Angular 5 with Apollo GraphQL and…
