Mzawadie API SDK

This package contains all queries and mutations that are used in our sample storefront. It can be used for semi-custom or fully-custom (with ability to extend existing queries) storefront solutions.

:warning: Note: Mzawadie SDK is still under heavy development and its API may change.

Setup

Setup

Custom implementation

npm install @mzawadie/sdk @apollo/client graphql

Create new mzawadie client by using our built-in pre-configured apollo client:

import { createMzawadieClient } from '@mzawadie/sdk'

const client = createMzawadieClient(API_URL)

Usage

React

We provide a custom hook per each query that have near identical API to react-apollo but are dynamically typed, with built-in error handling.

In your root file:

import { MzawadieProvider } from '@mzawadie/sdk'

const App = () => {
    const { authenticated, user, signIn } = useAuth();
    
    const handleSignIn = async () => {
        const { data, dataError } = await signIn("admin@example.com", "admin");
        
        if (dataError) {
            /**
            * Unable to sign in.
            **/
        } else if (data) {
            /**
            * User signed in successfully.
            **/
        }
    };
    
    if (authenticated && user) {
        return <span>Signed in as {user.firstName}</span>;
    } else {
        return <button onClick={handleSignIn}>Sign in</button>;
    }
};

const rootElement = document.getElementById('root')

const config = { apiUrl: "http://localhost:8000/graphql/", channel: "" };
const apolloConfig = {
    /* 
        Optional custom Apollo client config.
        Here you may append custom Apollo cache, links or the whole client. 
        You may also use import { createMzawadieCache, createMzawadieClient, createMzawadieLinks } from "@mzawadie/sdk" to create semi-custom implementation of Apollo.
    */
};

ReactDOM.render(
    <MzawadieProvider config={config} apolloConfig={apolloConfig}>
        <App />
    </MzawadieProvider>,
    rootElement
)

Using with NodeJS and other frameworks

npm install @mzawadie/sdk @apollo/client graphql

Then use createMzawadieClient to get Mzawadie api methods and internal config variables like channel and Apollo client.

import { createMzawadieClient } from "@mzawadie/sdk";

const client = createMzawadieClient({
    apiUrl: "<MZAWADIE_GRAPHQL_URL>",
    channel: "<CHANNEL>",
});

const { auth, config, _internal } = client;

Finally, API methods can be used:

const { data } = await auth.login({
    email: "admin@example.com",
    password: "admin",
});

if (data.tokenCreate.errors.length > 0) {
    /**
     * Unable to sign in.
     **/
} else if (data) {
    /**
     * User signed in successfully.
     **/
    const userData = api.auth.tokenCreate.user;
}

Features

We provide an API with methods and fields, performing one, scoped type of work. You may access them straight from MzawadieAPI or use React hooks, depending on which setup do you select.

API object	React hook	Description
`MzawadieAPI.auth`	`useAuth()`	Handles user authentication and stores data about the currently signed in user.
`MzawadieAPI.cart`	`useCart()`	Collects products to cart and calculates their prices.
`MzawadieAPI.checkout`	`useCheckout()`	Uses cart and handles the whole checkout process.
`MzawadieAPI.products`	`useProductDetails()`, `useProductList()`	Obtains products.
`MzawadieAPI.collections`	`useCollectionDetails()`, `useCollectionList()`	Obtains collections.
`MzawadieAPI.categories`	`useCategoryDetails()`, `useCategoryList()`, `useCategoryAncestorsList()`, `useCategoryChildrenList()`	Obtains categories.

Local development

Our aim it to build SDK, highly configurable, as a separate package, which you will not require modifications. Although if you want to alter the project, especially if you want to contribute, it is possible to develop storefront and SDK simultaneously. To do this, you need to link it to the storefront's project.

$ cd lib
$ npm link
$ cd <your storefront path>
$ npm link @mzawadie/sdk

Notice that in our example storefront webpack is configured to always resolve react to ./node_modules/react. It may seem redundant for the most use cases, but helps in sdk's local development, because it overcomes npm's limitations regarding peer dependencies hoisting, explicitly telling webpack to always have one and only copy of react.

Configuration

Set environment variables:

export API_URI=https://your.mzawadie.instance.com/graphql/
export TEST_AUTH_EMAIL=admin@example.com
export TEST_AUTH_PASSWORD=admin

Development

Download repository
Install dependencies: npm i
Now you can start files watcher with: npm run start

Production build

npm run build

Tests

Tests are located at /test directory. To start the test suite:

npm run test

All communication with API is prerecorded using Polly.JS. Unless requests changed or code executes new ones, no requests to API will be made.

Changes in /recordings directory should be reviewed before committing to make sure that changes in communication are intentional.

Code quality

The project has configured Prettier and ESLint. To check your code:

npm run lint

Fetch current GraphQL schema

npm run download-schema

Command will overwrite introspection.json with server schema, based on API_URL variable.

Updating TS types

GraphQL Code Generator is an automatic tool that converts schema to TS types. After changing schema file run:

npm run build-types

@mzawadie/sdk

Usage no npm install needed!
