e-mart is an open source full stack online mart complete with real credit checkout. Users can search, sell, add to cart and checkout their favourite grocery items.

This is a full stack JavaScript application built with React.js, GraphQL, Node.js and friends.

The following is the design of the frontend and backend of the application.

The application has five main models:

• Users
• Items
• Orders
• CartItems
• OrderItems

all of which are relational and utilizing the power of relational GraphQL Queries.

The app also includes many server side bits including:

• JWT authentication
• permissions
• sending email
• uploading images
• charging credit cards

Developer skills required to build an online mart with React, GraphQL and some of today's top JavaScript technology.

You should be already familiar with the basics of React - components, state, props, modules and event handlers.

You should be comfortable with both writing and debugging modern JavaScript including arrow functions, classes, promises, async+await and other commonly used parts of ES6.

The backend of the app is written in Node.js. Prior Node.js knowledge is nice, but not required.

The app requires knowledge of GraphQL, Apollo Client, Prisma, databases, or testing React components.

Just as React has transformed the way we build web applications, GraphQL is changing how we build APIs to query and mutate data.

GraphQL is a type-safe query language for APIs and a runtime for fulfilling those queries with your existing data.

What?! It's a replacement for (or addition to) your REST API and Ajax Calls.

GraphQL requires buy-in from both your client and your server — it then puts the power of requesting only what you want into the client and the business logic of finding and filtering that data into backend resolvers.

It enables libraries that make caching, loading, error handling and pagination a breeze.

Complex Relational Data queries and server-side mutations like signing up or checking-out are a snap with GraphQL.

GraphQL is just a standard and can be implemented in any language or framework.
